Abstract

The invention relates the hot roll oil. The invention uses biodegradation oil as base oil, uses ester as oiliness agent, and adds extreme-pressure agent, antirusting agent, anti-oxidant and metallic purifying agent. The technology comprises the following steps: mixing base oil, adding addition agent, heating to 50-70Deg.C, stirring them, filtering, and packaging. The invention has the advantages of improving surface finishment of steel plate, modifying surface state of roll, extending life, reducing draught pressure of rolling mill and motor working current, saving energy, environment protection and improving accuracy of measurement.

Description

technical field [0001] The invention relates to an oil for hot rolling process, which uses biodegradable synthetic oil as base oil, high-viscosity complex ester as oily agent, and then adds extreme pressure antiwear agent, antirust agent, antioxidant and metal deactivator Synthetic environment-friendly hot rolling oil made of additives such as Background technique [0002] In the process of steel rolling production, especially in the production process of hot-rolled steel plates, the rolls are in contact with the red hot (about 800-1000°C) steel plate surface, and the temperature of the roll surface is very high. With the increase of rolling volume, due to high temperature and high pressure The phenomenon of cracking and rusting on the surface of the roll is more common. In order to reduce the surface temperature of the working rolls of the rolling mill, prevent the roll surface from rusting, prolong the service life of the rolls, and improve ...
