Welding cinder ladle manufacture craft provided by the present invention is as follows:

Whole cinder ladle is made, board selection low-alloy high-strength plate Q345 makes, according to user environment temperature, the material of sheet material is carried out respectively corresponding selection from Q345B to Q345E, each parts respectively blanking are made, first trunnion seat assembly 1 first welds and assembles, then with behind Cylinder assembly location weld, cylindrical shell 2 (can adopt 1～3 pitch circle frustum docking by pressing machine press forming, every section of frustum of a cone adopts 2～6 sections of compactings to form), gussets etc. adopt numerical control blanking, at the bottom of flat bag, (see accompanying drawing 20, 21) adopt the preparation of low-alloy high-strength plate, finished product directly and cylindrical shell 2 weld.At the bottom of spherical bag, (see accompanying drawing 5,12) and adopt two kinds of methods to make: a kind of method is hot-forming, then with barrel soldering (because spherical bag Bottom Shape is simple, select bag end internal diameter 1000mm～1300mm, have forming mould to use more, significantly reduce manufacturing cost).Wherein barrel designs, according to the difference of load, volume, selects 60-100mm low-alloy high-strength plate to make; While adopting hot press forming technology to make at the bottom of spherical bag, bag each portion of the end can be made into uniform thickness, guarantee the support strength at the bag end and save material.Another kind is meticulous casting, uses the material close with cylindrical shell performance perameter, will at the bottom of bag, be optimized design, alleviates to greatest extent the bag weight at the end; Bag end weight only accounts for approximately 10% of gross weight.When adopting castmethod to make at the bottom of spherical bag, owing to belonging to foreign material welding, while weld seam carry load, whether weldquality is related to production can safe operation, therefore in order to ensure wrapping the reliable of the end and cylindrical shell weld seam, must consider from many-sides such as bag basal cross section, the structure of wrapping the end and cylindrical shell docking site coordination portion, overall construction design.Consider the bag supporting capacity at the end, the bag end is made into variable cross-section, the bag end, is consistent with thickness and the cylindrical shell of cylindrical shell joint, and from wrapping end upper edge hole to wrapping end lowest part thickness progressive additive, thickness is from 60-150mm.At the bottom of spherical bag and outside the butt weld of cylindrical shell, horizontal ring flat-plate 3 (seeing accompanying drawing 5) is set, horizontal ring flat-plate 3 is according to the difference of cinder ladle volume, take different thickness and ring flat-plate width, horizontal ring flat-plate 3 thickness 40-300mm, horizontal ring flat-plate 3 width (diametric(al)) are 100-300mm, at the bottom of spherical bag is held on the inclined-plane of horizontal ring flat-plate 3, share the load of bag end butt weld, horizontal ring flat-plate 3 has longitudinal gusset 5 (seeing accompanying drawing 1) of the thickness 40-80mm of circumference uniform distribution 6-12 bar to form reticulated structure up and down simultaneously, the load of bag end butt weld is shared by longitudinal gusset, act on cylindrical shell, strengthen the structural strength at the bag end and cylindrical shell position, (when wrapping the end and cylindrical shell butt weld place, expose with the vertical load of copper ashes in the bag butt weld shared bag at the end, example is structure as shown in figure 31, during all longitudinal gussets process butt welds, can offer fabrication hole, avoid butt weld, the bag end and the stressed of cylindrical shell butt weld are shared by longitudinal gusset), at the bottom of spherical bag, be designed to one side V-butt with the weld seam of cylindrical shell, groove angle 30-50 °, b is 3-10mm, through intensity, calculate, and consider the constructional feature of weld at the bottom of spherical bag, the bag end 8, is designed to fillet weld with the horizontal ring flat-plate 3 outside cylindrical shell 2 butt welds, foot welding height is 0.7 times of this thinner component thickness in position, and the structural strength of support from integral network structure, horizontal ring flat-plate 3 inclined-planes, the end and cylindrical shell combining site being guaranteed to wrap in three aspects of weld seam design is reliable.In addition, can also dock welding peripheral hardware with cylindrical shell 2 at the bag end 8 and put coaming plate 401, as shown in figure 28, coaming plate 401 welds with the bag end 8 and cylindrical shell 2 respectively, coaming plate 8 width are adjusted according to cinder ladle volume size, coaming plate thickness 40～100mm, and coaming plate can not only be shared the load of the bag end and cylindrical shell butt weld, simultaneously can adjust coaming plate width, make fillet weld position at the bottom of coaming plate and cylindrical shell and bag away from the heat affected zone of wrapping the end and cylindrical shell butt weld.Sometimes because cinder ladle physical dimension is subject to site technique condition restriction, when the bag end and cylindrical shell joint can not arrange ring flat-plate, the load of bag end butt weld place is shared by the circumferential uniform longitudinal gusset of cinder ladle outer wall, though this structural strength compared with the cinder ladle of [Dan slightly a little less than, but force analysis shows the cinder ladle intensity of this structure and meet service requirements, and the reparation that this structure design also makes to wrap the butt weld of the end and cylindrical shell is improved.

In the present invention, at the bottom of flat bag back welding connects cinder ladle and spherical bag cinder ladle all with cooling module, the quantity of the ring of two kinds of structure cinder ladles and similar.Facts have proved, in the situation that outer wall bipassage ring adds cooling-part, at the bottom of the cooling time of flat welding cinder ladle and spherical bag, cinder ladle approaches, in the situation that at the bottom of flat bag, cinder ladle outer wall ring flat-plate all adds cooling-part, cooling temperature that flat welding cinder ladle is cast cinder ladle is low 3 ℃～and 4 ℃, cast cinder ladle corresponding cooling time few about 10 hours.And spherical bag back welding connect cinder ladle will further improve flat welding cinder ladle in shortcoming slightly not enough aspect cooling performance, spherical structure of ladle bottom heat-dissipating space is large, and water coolant is more easily arrived wrap at the end.There is three kinds of water-cooleds, water-cooled+air cooling, air cooling mode in cinder ladle process of cooling simultaneously, due to water-cooled, water-cooled+air cooling, three kinds of types of cooling of air cooling, cooling efficiency successively decreases, the average cooling power of setting water-cooled, water-cooled+air cooling, air cooling is 1:0.5:0.25, set up desirable heat dissipation model, model cooling line from Figure 25 can find out, flat cinder ladle middle and lower part speed of cooling is slower.By Analysis deterrmination, improve the direction that structure design improves cooling efficiency, be about to flat change spherical bag at the bottom of.At the bottom of spherical bag, make the type of cooling of cinder ladle bottom change water-cooled+air cooling into by original air cooling, cooling efficiency significantly improves, and has solved the problem that flat cinder ladle middle and lower part volume is large and cooling conditions is poor.Welding in addition cinder ladle casts cinder ladle and can be easily at the ring flat-plate of cinder ladle outer wall, installs cooling-part additional, the water coolant that makes to go out from cinder ladle overflow is almost all collected and drains into cinder ladle outer wall, flow area and water amount all surpass casting cinder ladle, by making the original not welding cinder ladle of heating/cooling device cast cinder ladle long deficiency cooling time, become strong point.As shown in figure 29, water coolant in cylindrical shell flows out from the overflow groove of cylindrical shell upper edge hole, through water-blocking groove drainage, water coolant all drains into upper ring plate, because upper ring plate top arranges water collection sheet, therefore water coolant can not flow out from the edge of pressed on ring, and can only flow down from bypass channel or the tapping hole of ring flat-plate circumference uniform distribution, under each bypass channel or tapping hole of ring flat-plate, all correspondence is provided with a minute water plate, water coolant is from the bypass channel of ring flat-plate flows down along cinder ladle outer wall, through a minute water plate resistance gear, water coolant flows down along cinder ladle outer wall from minute water plate both sides, play the effect that increases water coolant flow surface, water coolant from minute water plate current of pressed on ring after, along cinder ladle outer wall, flow to second ring flat-plate, water is the same with first flowing of second ring flat-plate, per pass ring flat-plate all arranges coaming plate and divides a water plate, structure is identical, the flow pattern of water is identical.Minute water plate that the most lower one ring flat-plate configures, can be with flanging, to water coolant is more drained into cinder ladle bottom.

The present invention optimizes the cooling-part that cinder ladle outer wall arranges, and the water coolant that cinder ladle is overflowed is all collected, and successively drains into cinder ladle outer wall, and water coolant is flowed along cinder ladle outer wall, realizes the complete sufficient utilization of secondary of water coolant, at the bottom of particularly adopting spherical bag, keeping to greatest extent, welding cinder ladle structural strength is high, weldability is good, under the good prerequisite of reparation property, make to weld cinder ladle bottom heat radiation space and become large, make water coolant can arrive cinder ladle bottommost, greatly shorten cinder ladle cooling time, improve all transfer efficients of user's cinder ladle, overcome the not welding cinder ladle of heating/cooling device and compare the inferior position on cooling time with casting cinder ladle, simultaneously because welding cinder ladle outer wall has ring, from cinder ladle, the water coolant of overflow is under the drainage of refrigerating unit, along cinder ladle outer wall, flow down, can overcome the defect that casting cinder ladle outer wall can not install cooling-part additional, the flow area of welding cinder ladle outer wall is maximized, and Novel welding cinder ladle outer wall flow area is greater than casting cinder ladle, , greatly improve the cooling efficiency of cinder ladle, this will be less than casting cinder ladle the cooling time that make the welding cinder ladle at the bottom of spherical bag.Make to weld the multiple demand that cinder ladle can meet different user, will in copper ashes retarded cooling process, better be applied.
