采用现场试验与实验室试验相结合的方法,经百余次配方筛选后,选出YD-1、YD-2两种乳液配方,测定了乳液的油膜强度和摩擦系数,研究了乳液的浓度、pH、值、温度以及不同加工率等对拉拔力的影响。乳液可用于铜及黄铜薄壁管材拉拔加工,其拉拔力与菜油相当,与国内部分单位所使用的乳液相比,拉拔力可降低14～18％,与日本用于铜及其合金拉拔加工的一些油剂比较,其拉拔力相当或较优。采用浸液法拉拔管材可以避免管材表面氧化膜对拉拔力的影响,且可简化工艺,无废液排放。
Using the combination of field test and laboratory test, the formula of YD-1 and YD-2 was selected after screening more than one hundred times. The oil film strength and friction coefficient of the emulsion were measured. The emulsion concentration, The influence of pH, value, temperature and different processing rate on drawing force. Emulsion can be used for copper and brass thin-walled tube drawing process, its pulling force and vegetable oil quite, and some domestic units used in the emulsion, the drawing force can be reduced by 14 to 18%, with Japan for copper and its Alloy drawing processing some of the oil, the drawing force quite good or better. The use of immersion pipe drawing pipe can avoid the pipe surface oxide film on the pulling force, and can simplify the process, no waste discharge.
