Abstract
The invention discloses a method for horizontal continuous casting, Pilger rolling and continuous drawing of a copper alloy condenser tube. The method comprises the following steps of: 1) obtaining a tube blank in a horizontal continuous casting mode, and performing pre-straightening, tube blank face milling and Pilger cold rolling on the tube blank; 2) if the tube blank is made of brass, performing online continuous annealing and cam coupled stretching, then performing the online continuous annealing again, and entering step 4); 3) if the tube blank is made of white copper, performing direct coupled stretching; and 4) performing plate stretching on the tubular product for two times, and then performing joint stretching, finishing, cleaning, and final annealing to obtain a finished tubular product. The method can reduce the process steps of intermediate cutting, intermediate annealing, intermediate pickling and intermediate transfer, thereby effectively preventing products from transfer bump injuries, greatly improving the product quality, multiplying the production efficiency, eliminating metal pickling loss, and greatly reducing the production cost.
Description
Technical field
The present invention relates to a kind of preparation method of copper-alloy pipe-material, relate in particular to a kind of copper alloy condenser pipe horizontal casting-Pilger rolling-continuously elongated method.
Background technology
In the prior art, the copper alloy condenser pipe production technology is referring to accompanying drawing 1, tradition copper alloy condenser pipe production technology is: adopt the solid ingot casting of vertical D.C.casting explained hereafter, the scale sawing is the long short ingot of 400-600mm, to lack ingot and be heated to 800-1000 ℃ (it is different and different to look alloy species), obtain hollow bloom in the enterprising eleven punch 11 extruding of double-acting extruding machine.It is rolling that pipe is carried out carrying out after scale sawing, aligning, the pickling Pilger.Need be cut into the short tube of 4-6m to rolling pipe, with after annealing, pickling, system head, stretching; Pipe after the stretching also needs to be cut into the short tube of 4-6m, annealing once more subsequently, pickling, system head, stretching; 3-5 time so repeatedly, technological process is long, and the production passage is many; Extruding heating, annealing repeatedly, energy consumption is high; The loss of extrusion process frock is big, cost is high; The pickling process metal loss is big.Particularly product property low, can't production overlength copper alloy condenser pipe.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of copper alloy condenser pipe horizontal casting-Pilger rolling-continuously elongated method, it can address the above problem.
Above-mentioned purpose realizes by following proposal:
A kind of copper alloy condenser pipe horizontal casting-Pilger is rolling-continuously elongated method, it is characterized in that, and said method comprising the steps of:
1) mode by horizontal casting obtains pipe, described pipe is carried out face is milled in pre-straightening, pipe, Pilger is cold rolling;
2) if the pipe material is a brass, then carry out carrying out on-line continuous annealing once more after on-line continuous annealing, the stretching of cam bigeminy, enter step 4) afterwards;
3), then carry out direct bigeminy and stretch if the pipe material is a copper-nickel alloy;
4) tubing is carried out 2 passage dishes and stretches, join afterwards draw, finishing, cleaning, finished products obtain finished product tubing.
Can be referring to following flow chart accompanying drawing 2, according to said method, it is characterized in that: in step 1), the pipe of producing is the copper-nickel alloy pipe, use the intermediate frequency (IF) smelting stove of 500Hz to carry out melting, this smelting furnace capacity 3t, melting rate 1.8t/h, power 750Kw, and the copper-nickel alloy pipe specification that obtains is Ф 88 * 10mm/mm; Holding furnace adopts main frequency furnace, capacity 5t, power 250Kw.
According to said method, it is characterized in that: in step 1), the pipe of production is a brass pipe blanks, uses power frequency smelting furnace to carry out melting, the capacity 4t of this smelting furnace, melting rate 2.0t/h, power 550Kw, and the brass pipe blanks specification that obtains is Ф 96 * 11 mm/mm; Holding furnace adopts main frequency furnace, capacity 5t, power 250Kw.
According to said method, it is characterized in that in step 1), pipe mills face size 0.2-0.3 mm/mm.
Use method of the present invention to reduce process procedure 60% than traditional handicraft; Improve casting lumber recovery about 9%; Omit ingot casting heating-perforation extrusion process, be equivalent to improve operation lumber recovery 10-12%; Reduce ingot casting heating-extrusion process energy consumption 800KWh/t, reduce compression tool loss and 450 yuan/t of personnel's wage cost copper; Cut in the middle of reducing, intermediate annealing, middle pickling and middle transhipment operation, effectively prevent goods transhipment bump injury, product property increases substantially, production efficiency is multiplied, and has eliminated the acid-washed metal loss, production cost reduces significantly.
