50 years to the early 60s, began to use soap powder as the top of the powder, that is, sodium stearate-based ordinary soap made of dry powder products, designed for use when drawing. This is more economical and convenient than using industrial soap, but the adhesion is serious.
In the early 1970s, the chemical plants in Yingkou City of Tianjin began to develop dry-drawing lubricants for use in drawing steel. They produce calcium soap products with good adsorption, high thermal viscosity, to prevent adhesion performance, easy to use, cheap and so on. Therefore, the popularity of faster, but also to adapt to the already improved wire drawing speed. And some manufacturers made of complex soap for drawing different products, but also achieved very good results. 80 years with the implementation of the reform and opening up policy, some of China's metal products enterprises from foreign advanced countries to introduce a number of the world's advanced level of high-speed drawing machine, at the same time, through digestion, absorption, localization, new high-speed wire drawing machine increased. At that time, China's drawing lubricant can not be these new high-speed drawing machine to play out the effectiveness. Therefore, seeking to adapt to the high-speed drawing machine, developed to adapt to different drawing conditions of a variety of professional lubricants were put on the agenda, and increasingly attention. After years of testing, research, at present, China's drawing lubricant development has made remarkable achievements.
