Problems solved by technology
For a long time, traditional formulations have used chlorinated paraffin and ordinary mineral oil as the main ingredients, but with the high toxicity of chlorinated paraffin and the destruction of the ecological environment, people especially hope to use new non-toxic main ingredients to replace it
However, for a long time, replacing chlorinated paraffin with oil-soluble phosphate and sulfur-containing compounds has not yet reached the ideal effect of traditional formulations, and the odor of oil-soluble phosphate and the (toxicity) of its ortho isomers are difficult to separate and remove. Its popularization and application has been challenged and limited

The invention discloses a water-soluble rolling oil used as a liquid state composition for lubricating, cooling and resisting rust during the rolling of stainless steel, comprising 15-25 percent of castor oil, 50-62 percent of purified water, 3-7 percent of coupling agent, 3.5-4.0 percent of addition agent and 13-25 percent of addictive. The water-soluble rolling oil is prepared by the steps of saponifying the castor oil, the coupling agent and the addition agent and then adding the addictive and mixing. The addictive comprises an antiwear agent, an antioxidant, an antirusting agent, a pH adjusting agent and a defoaming agent. The liquid state composition has the advantages of favorable lubrication performance, high cleanliness, excellent glossiness of a rolled plate surface, strong cooling effect, no toxicity, no combustion and favorable biodegradation rate and is especially suitable for fine rolling process oil (agent) of stainless steel plates.
Description
Technical field: [0001] The invention relates to a liquid composition used for lubricating, cooling and rust prevention in the rolling process of a stainless steel continuous rolling mill. Background technique: [0002] In the stainless steel rolling process, the use of lubricant is the key to improving the surface quality of the plate, obtaining a satisfactory rolling reduction rate (25-30%), prolonging the service life of the roll (machine), and realizing environmental protection and energy saving. For a long time, traditional formulations have used chlorinated paraffin and ordinary mineral oil as the main ingredients, but with the high toxicity of chlorinated paraffin and the damage to the ecological environment, people especially hope to use new non-toxic main ingredients to replace it. However, for a long time, replacing chlorinated paraffin with oil-soluble phosphate and sulfur-containing compounds has not yet reached the ideal effect of traditional formulations, and t...
