Abstract
The invention discloses a no-pickling cold drawing processing method of a steel wire, which comprises the following steps of: (1) selecting a steel wire blank with the external diameter of 5.50 for spheroidizing annealing, (2) performing cold drawing for the first time, (3) performing annealing treatment: annealing temperature at 680-700 degrees and heat preservation period for 5h, then shutting down a furnace, cooling a steel wire rope to below 250 degrees, discharging, naturally cooling in air, (4) performing cold drawing for the second time, and (5) oiling and packaging. The method does not adopt any chemical method, but adopts a pure mechanical method, thereby greatly lowering a pollution level.
Description
Technical field
The present invention relates to a kind of steel wire non pickling cold-drawing processing method.
Background technology
The steel wire rope that the object that wire cold-drawing is processed makes outside dimension larger, through processing, is reduced into the steel wire rope that external diameter is less.The step of current wire cold-drawing processing method is as follows roughly successively: steel wire base, spheroidizing, first time pickling, cleaning, neutralize, dry, first time cold-drawn, annealing, second time pickling, cleaning, neutralize, dry, second time cold-drawn, oil, pack.First time pickling is in order to remove the oxide skin on steel wire base, and second time pickling, in order to remove the oxide skin after wire annealing, relies on hydrochloric acid or sulfuric acid solution to remove like this, has serious pollution, and also have the injury of health to operator to environment.And after pickling, also need to carry out electrolytic phosphating or chemical phosphatization, be coated with last layer phosphate layer on the surface of steel wire rope, so also need to rely on Phosphating Solution, have serious pollution to environment, and also have the injury of health to operator.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of without the steel wire non pickling cold-drawing processing method adopting any chemical method, adopt pure machinery, greatly can reduce the pickling-free cold-drawn of pollution level processing.
Technical scheme of the present invention is, provides a kind of steel wire non pickling cold-drawing processing method with following steps: it comprises the following steps:
(1), selection external diameter is the first spheroidizing of steel wire rope of φ 5.50mm;
(2), first time cold-drawn: carry out cold-drawn by the machine drawing of a connection, after steel wire rope enters successively through one group of directive wheel for stretching steel wire rope, about one group be dislocatedly distributed and all horizontal by the steel brush of 45 degree, one group of running roller, another organize be dislocatedly distributed up and down and all horizontal by 45 degree steel brush, another organizes running roller; Then successively in four groups hole size be respectively φ 4.70mm, φ 4.16mm, φ 3.66mm, φ 3.26mm dog wear mould, make finally to become the steel wire rope that external diameter is φ 3.26mm; Steel wire rope linear speed through connection machine drawing is 140 ~ 170 ms/min; Open the dust catcher of connection machine drawing simultaneously;
(3), annealing in process: annealing temperature 680 ~ 700 degree, temperature retention time 5 hours, closes stove afterwards, and steel wire rope is cooled to less than 250 degree and comes out of the stove, in atmosphere naturally cool;
(4), second time cold-drawn: carry out cold-drawn by the machine drawing of an other connection, after steel wire rope enters successively through one group of directive wheel for stretching steel wire rope, about two groups be dislocatedly distributed and all horizontal by the steel brush of 45 degree, one group of running roller, another organizes and to be dislocatedly distributed up and down and all horizontal by the polishing cloth (4) of 45 degree; Then successively in four groups hole size be respectively φ 3.00mm, φ 2.66mm, φ 2.34mm, φ 2.12mm dog wear mould, make finally to become the steel wire rope that external diameter is φ 2.12mm; Steel wire rope linear speed through connection machine drawing is 140 ~ 170 ms/min; Open the dust catcher of connection machine drawing simultaneously;
(5), oil, pack.
After adopting above method, the present invention compared with prior art, has the following advantages: due to the oxide skin not adopting any chemical method to remove steel wire rope surface, and directly adopts many group steel brush machineries to remove, eliminate and have serious pollution to environment, and eliminate the actual bodily harm to operator.Again owing to changing original phosphorating treatment into oiling treatment, which also eliminates and have serious pollution to environment, and eliminate the actual bodily harm to operator.
