Abstract

The invention relates to a novel cold forging processing lubricant capable of reducing waste liquid and a preparation method thereof. The lubricant is prepared from the following components in percentage by mass: 30 to 50 percent of base oil, 10 to 20 percent of lubricant, 20 to 40 percent of phosphoric acid, 15 to 30 percent of extreme pressure agent, 5 to 10 percent of ferric salt, 1 to 5 percent of coupling agent and 1 to 5 percent of deionized water. The method is mainly used for the drawing process after phosphating of the surface of the steel pipe; the lubricant can form a compact reaction film with the surface of the steel pipe at a certain temperature for a certain period of time; the effects of reducing friction, improving lubrication, improving production efficiency, saving energy and reducing generation of waste liquid in the metal cold forging machining process are achieved, the novel cold forging processing lubricant belongs to an environment-friendly product, and the drawn steel pipe is mainly used for automobile steering columns, pipes for transmission shafts, engine oil and gas pipes, pipes for fluid pipelines, mechanical hydraulic pipes and the like.

Description

technical field [0001] The invention relates to the field of steel pipe phosphating and drawing, in particular to a novel cold forging lubricant for reducing waste liquid and a preparation method thereof. Background technique [0002] Steel pipe is a kind of economical steel, which is used in various industries such as transportation and machinery manufacturing. It can reduce weight, save metal by 20-40%, and realize factory-like mechanized construction. In the drawing process of steel pipe, the choice of lubricant is particularly important. [0003] The traditional steel pipe drawing is a process of phosphating and saponification. Through the action of phosphating solution, a dense phosphating film is produced on the surface of the steel pipe, which can eliminate the friction between the steel pipe and the mold. After washing, cold drawing is carried out. A large amount of waste water and waste residues are produced, which does not meet the requirements of energy conservat...
