Problems solved by technology

What's more serious is that this rolling oil contains aromatic hydrocarbons-aromatic hydrocarbons are a kind of carcinogens, which seriously affect the physical and mental health of workers, become moldy and smelly in summer, pollute the environment, and the waste liquid cannot meet the requirements of the three wastes treatment Emission Standards
The surface of the steel plate produced by using this rolling oil can not reach the ideal smoothness. Therefore, it is urgent to study a new type of rolling oil to meet the needs of the steel rolling market.

Abstract

The invention belongs to the technical field of rolling oil, and discloses rolling oil used in the process of machining metals and a preparation process for the rolling oil. The rolling oil is technically characterized in that the rolling oil is prepared by stirring phosphoric acid, triethanolamine, a lubricant, a pH value regulator, sodium thiosulfate, Ninol, an antirusting agent, an emulsifier and water. The rolling oil does not contain mineral oil or aromatic hydrocarbon, so the rolling oil is favorable for the health of operators; and when the rolling oil is used for producing steel plates, friction force between rolled workpieces can be reduced effectively. The rolling oil has the characteristics of reducing calendaring loads effectively in the calendaring process, ensuring the glossiness of the rolled workpieces and relieving abrasion between the workpieces.

Description

technical field [0001] The invention belongs to the technical field of rolling oil, and relates to a rolling oil used for lubricating and rust-proofing when rolling steel and steel plates and a preparation process thereof. Background technique [0002] Rolling oil is a kind of oil used in metal material processing or rolling process to reduce the friction between the rolled piece and the roll, reduce the rolling load during the rolling process of the metal sheet, and ensure the smoothness of the rolled piece. Taste. At present, the rolling oil used in our country is still based on the mechanical oil as the carrier, and is formulated with various organic additives. This rolling oil product is a product of World War II. It has not been developed for more than 60 years. It competes with the world for mineral oil that is both valuable and non-renewable, and at the same time, it is expensive. What's more serious is that this rolling oil contains aromatic hydrocarbons-aromatic h...
