Description
Technical field
The present invention relates to a kind of blast furnace tuyere small sleeve preceding cap spin forming devices and its technique, belong to blast furnace process equipment
Technical field.
Background technique
Blast furnace tuyere small sleeve used at present, is all the small set being made by metallic copper, and blast furnace tuyere small sleeve is in furnace
Cylinder position.The hot wind that temperature is 1100 DEG C~1200 DEG C sprays into blast furnace in tuyere small sleeve, and tuyere small sleeve is easy by hot wind melting loss,
The slag iron corrosion dripped causes service life very short, such as handles and is easy not in time to cause safety or production accident, give blast furnace
Production cause great inconvenience.
Currently, the moulding process of preceding cap used in blast furnace tuyere small sleeve is to squeeze to be made on heavy-duty press using copper rod,
It is this to be had the following deficiencies: using preceding cap obtained by extrusion process
1, front end will appear indetectable tiny slag inclusion, interlayer, crackle, these tiny defects are in punching press, welding, pressure testing
Process that it is extremely difficult be tested out, but in tuyere small sleeve use process, the front end of tuyere small sleeve can be made to generate tiny
Cracking reduces air port thermal radiation resistance ability, air port is caused quickly to be scrapped；
2, extrusion length is no more than 380mm, because of the limitation of punch process itself, the extensibility of material has certain pole
Limit cannot process deep barrel-shaped product；
3, the inner wall of cap, generates the drawing trace of certain depth before draft process convex mould can be pulled, and this drawing trace quantity is excessive, and
Unavoidably, the tensile strength of cap before influencing；
4, because squeezing preceding cap limited length, this results in the water cavity space at tuyere small sleeve rear portion huge, and huge water cavity can produce
Raw excessive slough, also reduces out water speed, causes head resistance to increase, influences to radiate；
5, the gas that rear portion water cavity remains in more greatly back cavity will be more, and air port is fine copper product, and fine copper is thermally conductive fast, either wind
Mouth front end or rear end, Anywhere existing influences thermally conductive factor, just will affect the heat dissipation effect of air port entirety, accumulates over a long period
The crystal structure and fatigue strength of material and weld seam will be reduced.

A kind of preceding cap flow forming and molding process of blast furnace tuyere small sleeve, comprising the following steps:
Step 1 prepares copper cake blank；
Step 2, heating copper cake blank；
Step 3 places copper cake blank；
Step 4, shear spinning copper cake blank.
In step 4:
Start spinning cranking wheel control system, spinning wheel not active rotation itself, spinning wheel with copper cake blank by connecing
The frictional force that touching generates passively rotates, and spinning wheel, the revolving speed of copper cake blank and core model and blast furnace tuyere small sleeve are revolved with preceding cap
The revolving speed of the live spindle of press forming device is identical, and speed is 120~260r/min；
The position that spinning wheel contacts copper cake blank first is between the step of matrix and tail top end, then spinning wheel along with X
The axial track operation in 4.1 degree of angles, angle are identical as the gradient of matrix.
The step 4 divides three phases to carry out spinning: falling, pattern and extension；
The three phases are as follows:
1st stage was that copper cake blank was fallen, and the X axis amount of feeding of 4 spinning of this stage point, each spinning wheel turns for 2mm/,
1~1.5mm is thinned in each spinning copper cake blank thickness, and each spinning all fell copper cake blank, until copper cake blank is whole
Cone cylinder shape is presented in body；The inner wall and core model of cone cylinder have certain gap, and gap is 5~7mm, this stage blank thickness is thinned 4
~6mm, this stage need time-consuming 9~11 minutes, this stage main motor revolving speed is 35~45r/min；
2nd stage is that spinning wheel is applied to the cone cylinder inner wall that the 1st stage was formed on core model by rotary squeezing；This stage point
The X-axis amount of feeding of 4 spinning, each spinning wheel turns for 2mm/, and 2mm, this stage blank thickness is thinned in each copper cake blank thickness
Be thinned 8mm, the 4th spinning cone cylinder inner wall is applied on core model completely, i.e. pattern, this stage main motor revolving speed be 115~
125r/min；
3rd stage be copper cake blank wall thickness continue it is ironed, extend spinning conic tube in the X-axis direction；This stage point 3~
4 spinning, except the X-axis amount of feeding of last time spinning wheel is in addition to 1mm/ turns, remaining each spinning copper cake blank thickness is thinned
1.5mm；This stage main motor revolving speed is 195~205r/min, and barrel lenght and wall thickness all reach prescribed requirement i.e. only.
In step 2:
Copper cake blank is put and is heated to 850 °~870 ° into heating furnace, heating time is 3 hours, keeps the temperature 2 hours.
In step 3:
Copper cake blank is sling in heating furnace, copper cake blank is put the core to blast furnace tuyere small sleeve with preceding cap spin forming device
On mould；
The X-axis of the preceding cap spin forming device of tail top edge blast furnace tuyere small sleeve of the preceding cap spin forming device of blast furnace tuyere small sleeve
Direction is mobile, and tail top is moved at copper cake blank, and the tail top cover cylinder on tail top is pressed on copper cake blank on the end face of core model, tail top
First part insertion copper cake blank centre bore carry out to just, then the second part and Part III on tail top are to copper cake blank
It is squeezed, forms copper cake blank to the poroid of in-flanges.
After the invention adopts the above technical scheme, compared with prior art, have the advantage that using produced by the present invention
It is strong that the preceding cap of blast furnace tuyere small sleeve is less prone to relatively fine crackle, preceding cap compactness, and preceding cap is in deep tubular, the rear portion water cavity of preceding cap
Water cavity is short, and space is small, is suitable for that the water cavity of size reduces the delay of cooling water, increases the rate of output water of cooling water, the resistance of head
Power is smaller, increases rate of heat dispation；
Prolonged the service life 2-3 times using the preceding cap of blast furnace tuyere small sleeve produced by the present invention relative to cap before punching press, uses the longevity
It orders longer Qiang Xuanqian cap and reduces replacement；
Moulding process of the blast furnace tuyere small sleeve of the present invention with preceding cap flow forming and molding process relative to cap before punching press saves material, is not required to
Want secondary operation precision controllable, the Qiang Xuanqian cap of deep tubular is relative to the thermally conductive raising 30% of cap before short tubular punching press；
It being applied in combination using preceding cap, back seat and the baffle of blast furnace tuyere small sleeve produced by the present invention, cooling water channel is extended,
Water flow velocity improves, and heat transfer speed is accelerated, and good cooling results make tuyere small sleeve front end water cavity water flow velocity and tuyere small sleeve entirety water
Flow more tends to rationalize, through in 1080M3Blast furnace scene water testing, measure average water flow be 25-27 M3/h。
It can achieve 500mm using the length of the preceding cap of blast furnace tuyere small sleeve produced by the present invention, and cap is maximum before squeezing
Length is 350mm, 3000M3Above blast-furnace tuyere length is 600mm to 700mm, if preceding cap is short to make rear portion backwater cavity mistake
Greatly, air port can be bent from backwater cavity in use process.If reaching the Qiang Xuanqian cap of 450mm or more using length, make rear portion
Return water cavity length shortens, and water cavity space reduces, and backwater cavity position is not in bending phenomenon.
