Problems solved by technology

[0003] The huge steel production has enabled a large number of small and medium-sized cold-rolling enterprises to survive, but most of the cold-rolling lubricating materials they use are still relatively outdated. They use ordinary emulsions and auxiliary lubricants for lubrication. The auxiliary lubricants cannot be recycled, and the finished products are annealed. The detergency and environmental performance are poor, and ordinary emulsions contain a large amount of formaldehyde fungicides, which are harmful to the environment and human body
At the same time, the relatively low lubricating performance will lead to shortened roll life, fast replacement cycle of rolling mill bearings, and high comprehensive energy consumption of rolling mills, which are contrary to my country's energy-saving and emission-reduction related policies.

Abstract

The invention belongs to the technical field of lubricating materials and discloses a lubricating material for cold rolling and its preparation method and use. The lubricating material for cold rolling comprises, by mass, 20-60% of base oil, 0.3-1% of an anti-oxidant, 20-60% of a lubricant, 3-10% of an extreme pressure agent, 0-5% of an antirust agent, 1-3% of a purification dispersant, 3-9% of an emulsifier, and 2-6% of an anionic surfactant. The lubricating material is especially suitable for a four-roller four continuous rolling unit having the size of 650mm and high lubricity requirements, does not contain chlorinated paraffin, prevents stress corrosion on a cold-rolled finished product, and has excellent lubricity. Compared with the common emulsion on the current market, the lubricating material reduces a rolling force by 7-10%, prolongs a roller service life by 10-15%, reduces comprehensive energy consumption by 10-15% and effectively prolongs a rolling mill bearing service life.

Description

technical field [0001] The invention belongs to the technical field of lubricating materials, in particular to a lubricating material for cold rolling and a preparation method thereof. Background technique [0002] In recent years, my country's steel industry has developed rapidly. In 2012, the steel output reached 700 million tons, ranking first in the world. More and more new metal processing equipment, new technologies and new processes have been applied in domestic enterprises. In 2009, the State Council promulgated the steel industry and non-ferrous metal adjustment and revitalization plan, which further clarified the tasks of enterprise technological progress and production energy conservation and emission reduction, and accelerated the transformation of the steel industry from large to strong. It is also predicted that my country's crude steel demand may enter the peak arc top area during the "Twelfth Five-Year Plan" period, and the highest peak may appear in the per...
