Abstract

The utility model provides a plant for continuously galvanizing tubes by heat. The utility model adopts the continuous production line plant to overcome the problem that galvanized steel tubes cannot be continuously produced in the prior art. Along the direction of the production line and close to steel tubes are sequentially connected an uncoiler (1), a crop shear (2), a first pinch roll (3), a steel plate welder (4), a pinch roll (5), a disc type repeater (6), a second pinch roll (7), a straightener (8), a roll forming machine (9), a straight seam welder (10), a preheating cleaner (11), a zinc bath (12), a circular air knife (13), a cold air sweeper (14), a steel tube pinch roll (15), a cut-to-length following shear (16) and a stacking machine. The stacking machine is provided with two stackers, one of the stackers is in use, the other stacker is spare, the production efficiency is increased, and the cost is saved.

Description

A kind of equipment of continuously and thermally galvanizing pipe

Technical field

The utility model belongs to and is coated with zinc-plated field in the metallurgy industry, relates in particular to the production field of pot galvanize.

Background technology

The employing that the production of domestic original galvanized pipe now has is electroplated, and the employing galvanized sheet that has is welded, and adopts the method galvanized pipe of electro-galvanizing, thickness of coating is difficult to control, and coating is thinner, and production rate is slow, the cost height, and pot galvanize adopts cage to soak zinc-plate process mostly, and steel pipe is cut into the length that needs, and is placed on to immerse the zinc pot in the cage, galvanizing in this way, the zinc layer that is plated is the two sides, and practical application just outer surface of steel tube need zinc-platedly, the double side zinc coating waste is serious; Technology with the galvanized sheet welding is roll-forming on heat zinc coating plate in addition, is welded, and postwelding is mended zinc coating then in the reconditioning of steel pipe seam place in the commissure.Zinc-plated on steel pipe, low with these several mode production efficiencys, can not continuous production, complex procedures, production cost is big, and labour intensity is big.

Summary of the invention

Low in order to overcome domestic original galvanized pipe production efficiency of equipment, the production cost height, can not continuous production, labour intensity is big, the mode that the utility model adopts the production unit of working continuously is zinc-plated and shear that all processes is all online to be finished to being welded into steel pipe from uncoiling, collection uncoiling, leveling, roll-forming, welding, cleaning, cold wind purging, cutting to length, buttress material equipment are one, be used for the full continuous automatic production of hot dip galvanizing pipe, can continuous production, thereby improved production efficiency, filled up domestic blank.

The technical scheme in the invention for solving the technical problem is: adopt a kind of equipment of continuously and thermally galvanizing pipe, along the production line direction by steel band connect successively that Abrollhaspel 1, crop end cut that 2, first pinch roll 3, steel plate welding machine 4, pinch roll 5, disc type kink 6, second pinch roll 7, equipment for straightening 8, roller pressing forming machine 9, Straight seam welding machine 10, pre-warm wash 11, zinc groove 12, the air knife 13 that goes in ring, cold wind purge 14, steel pipe pinches 15, fixed length cuts 16 subsequently, stacking apparatus.

In the described zinc groove 12 zinc pump and nozzle are arranged.

Described fixed length is cut the parts that have the cut-to-length parts in 16 and move with steel pipe subsequently.

Described stacking apparatus has two stackers, the using and the reserved.

The beneficial effects of the utility model are: the configuration of this continuously and thermally galvanizing pipe apparatus for production line can be finished from uncoiling zinc-plated and shear that all processes is all online to be finished to being welded into steel pipe, collection uncoiling, leveling, roll-forming, welding, cleaning, cold wind purging, cutting to length, buttress material are one, realize the online full continuous production of whole process of production; Reduced middle-chain, saved manpower, the method with the continuous zinc coating pipe has reduced zinc consumption, has reduced production cost, has improved production efficiency, has improved the level of automation of producing, and has saved manpower and materials, has improved quality of coating.

Embodiment

Entrance: earlier coil of strip is placed on the Abrollhaspel 1 with the coil of strip car, wrench is cut 2 with crop end and is cut wrench, flatten by steel plate welding machine 4 through first pinch roll 3, cutting 2 with last coil of strip through crop end, to cut the steel plate afterbody of irregular magnetic tape trailer welded together, change the locality of steel band by pinch roll 5, make steel band become vertical direction and enter disc type kink 6 by horizontal direction, steel band enters disc type kink 6, during normal uncoiling, disc type kink 6 storings, when change of lap welds, disc type kink 6 blowings satisfy the requirement of unit quantity-produced;

Process section: steel band comes out to turn to through second pinch roll 7 from disc type kink 6, make steel band become horizontal direction by vertical direction, through equipment for straightening 8, steel band is carried out straightening processing, eliminate the defective of steel strip surface, help next step soldering of steel band, enter roll-forming machine equipment 9, behind roll-forming, be rolled into steel pipe, be welded into steel pipe through Straight seam welding machine 10, the steel pipe seam place of postwelding is polished flat with sander, enter pre-warm wash 11, with cleaning through the tank liquor after the preheating, wash the iron scale of steel tube surface, steel band enters rinse stage then, washes the remaining tank liquor of steel tube surface off, then steel pipe enters the oven dry section, and hot-air seasoning is removed the moisture of steel tube surface.Steel pipe behind hot-air seasoning is through pinching, enter zinc groove 12, the zinc pump is arranged in the zinc groove 12, zinc liquid sprays to steel tube surface to zinc liquid through the zinc pump by the nozzle that goes in ring, unnecessary zinc liquid flows back in the zinc groove 12, zinc pipe after the spraying is through the air knife 13 that goes in ring, blow unnecessary zinc liquid off, thus the thickness and the uniformity coefficient of the air knife air output of gate ring promoting the circulation of qi cutter 13 control zinc coating, the quality of control zinc coating.The key of decision steel pipe finished product.

Outlet section: the steel pipe after zinc-plated purges 14 postcooling through behind the annular air knife through cold wind, pinching 15 through cooled steel pipe through steel pipe enters fixed length and cuts 16 subsequently, fixed length is cut 16 subsequently and is followed the steel plate walking, the length that requires according to required steel pipe customizes, shear steel pipe, the steel pipe scale is become fixed length, to reach the production needs, steel pipe after the fixed length enters two stackings 17, this equipment is used for carrying the finished product to length steel pipe, and shared two, the using and the reserved, when a stacking apparatus reaches the stacking height discharging of regulation, by handling equipment fished pipe is delivered to another stacking apparatus, continue stacking, satisfy unit quantity-produced needs, save the production time, improved production cost.
