〔産業上の利用分野〕
本発明は、塑性加工用の金属製バイブ、線材等の酸洗法
に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a pickling method for metal vibrators, wire rods, etc. for plastic working.
従来、ステンレス鋼パイプ、鉄パイプ、＠線等の金璃材
料を伸線、引抜き等の方法により冷間塑性加工するに際

。Conventionally, when cold plastic working metal materials such as stainless steel pipes, iron pipes, and wires by methods such as wire drawing and drawing, these metal materials are subjected to pickling, water washing, neutralization, temporary rust prevention, and lubrication treatment. Alternatively, the plastic workability is improved by performing pickling, water washing, chemical conversion treatment, water washing, neutralization, temporary rust prevention, and lubrication treatment.
この工程における酸洗は、脱鑓及び脱スケール性を向上

及び酸洗液中への金属材料物搬入による酸洗液の温度低
下の問題があった。The pickling in this step may be carried out by maintaining hydrochloric acid or nitric-fluoric acid at a temperature of 30 to 40°C and sulfuric acid at a temperature of 50 to 70°C in order to improve descaling and descaling properties. In order to maintain heating at this temperature, the heating tube is heated by immersing it in the pickling solution, but since the temperature near the heating tube is much higher than the average temperature of the pickling solution, the heating tube may be corroded by the pickling solution.
There was also the problem of a drop in the temperature of the pickling solution due to the introduction of metal materials into the pickling solution.
又金属材料表面に付着している油脂、潤滑剤等の異物が
原因となって、金属材料を酸洗するとその表面に酸洗む

った。Also, pickling metal materials has the disadvantage that pickling causes uneven pickling on the surface and shortens the life of the pickling solution due to foreign substances such as oils and lubricants adhering to the surface of the metal material. Ta.
本発明は、酸洗液による加熱管の腐食、酸洗液の金属材

いる。The present invention aims to solve the problems of corrosion of heating tubes due to pickling liquid, temperature drop due to pickling liquid carrying metal materials, uneven pickling on the surface of metal materials, and shortening of the life of pickling liquid. .

。As a result of various researches to solve the problems described in MU, the non-inventor discovered that if the metal material for plastic working is treated in advance with hot water at a temperature equal to or higher than that of the pickling solution and then pickled, the above problem can be solved. We found that this problem could be solved and solved this problem.
この湯水の温度は、外気による酸洗液の温度低下及び温
度維持を考慮して、酸洗液の温度よりも５〜２０℃高く
維持するのが好ましい。The temperature of the hot water is preferably maintained at 5 to 20° C. higher than the temperature of the pickling solution, taking into account the temperature reduction and temperature maintenance of the pickling solution due to outside air.
湯洗水に、脱脂性を向上させるために界面活性剤を添加

湯水温度と略同程度になる時間行えば良いが、その時の
作業の状態によってもつと長く処理してもかまわない。The treatment method using hot water is carried out by immersion method, spray method, etc. In continuous work, the treatment time should be the time when the metal material temperature is approximately the same as the hot water temperature, but the treatment time may vary depending on the work at that time. Depending on the situation, it may be possible to process for a longer period of time.

う。Effect] When metal materials for free processing are treated with hot water at a temperature equal to or higher than that of the pickling liquid at 30 to 70°C, foreign substances such as oils, fats, lubricants, etc. attached to the metal material temperature are removed. Moreover, the temperature of the metal material becomes about the same as that of hot water. When the metal material is carried into the pickling solution for the next step, the temperature of the pickling solution is maintained by the temperature of the metal material itself. During this time, the temperature of the hot water is adjusted so that the set temperature of the pickling solution can be maintained.

により加熱する。At the start of pickling work, if the temperature of the pickling liquid cannot be maintained at the set temperature due to intermittent work, etc., the pickling liquid is heated using a heating pipe or the like provided in the pickling liquid tank.

It was immersed in a 12-13% sulfuric acid solution for 20 minutes. There was almost no temperature fluctuation in the sulfuric acid solution during immersion. Next, it was removed from the sulfuric acid solution, washed with water, treated with phosphate, and its surface condition was observed. As a result, a phosphate film was uniformly formed.

た。This treatment was carried out at a rate of 23 to 27 coils per day for one year. As a result, in order to smoothly proceed with the pickling work for derusting and descaling, it was necessary to discard and renew the sulfuric acid solution for 15 to 6 days at a time. The heating tube used was a Teflon-coated iron tube, which could be used for 1 year without needing to be replaced.

Also g
The phosphate film formed on the 4 wires was uneven, and the sulfuric acid solution had to be disposed of and renewed once every 4 to 5 days. The heating tube had to be replaced twice a year due to cracks in the Teflon coated skin and corrosion of the iron material.

。In the invention, by treating the metal for plastic working (original material) with hot water, foreign substances such as oils and lubricants on the surface are removed, so uniform etching can be achieved during pickling. The life of the pickling solution can be extended because foreign matter does not get mixed into the pickling solution.The temperature of the metal material carried into the pickling solution is heated by hot water at a temperature equal to or higher than that of the pickling solution. The temperature of the pickling solution can be easily adjusted.Since the pickling solution does not need to be heated much by the heating tube, corrosion of the heating tube due to heating can be prevented.
