Problems solved by technology

[0002] Before the fully synthetic rolling fluid was used, the process lubricant used in the four-high rolling mill was usually an emulsion, but the surface quality after rolling was poor, and the temperature control equipment needed to be turned on and maintained at a temperature of 45-55 °C, and stirring was required. Prevent spoilage and rancidity
Another point is that the four-roll rolling mill uses the emulsion to change the liquid, the period is short, and it only takes 1 to 2 months to replace it all. Frequent liquid changes have an impact on production, and the overall cost of using the emulsion is high. Emulsion for improvement

Abstract

The invention relates to a novel milling liquid for a four-roll mill and a preparation method thereof. The novel milling liquid for the four-roll mill at least comprises the following components by volume percent: 15 to 25% of polyols, 25% to 35% of trithylenetramine, 5% to 10% of inorganic alkali, 8% to 10% of additive and the balance of water. The novel milling liquid for the four-roll mill changes emulsion into completely synthesized liquid, has long service life which is 6 to 7 times longer than that of the emulsion; and the liquid can not easily generate degeneration, rancidity or bacteria and completely contains no emulsifier or mineral oil.

Description

technical field [0001] The invention relates to a rolling liquid for metal processing and a preparation method thereof, in particular to a novel four-high rolling mill rolling liquid and a preparation method thereof. Background technique [0002] Before the fully synthetic rolling fluid was used, the process lubricant used in the four-high rolling mill was usually an emulsion, but the surface quality after rolling was poor, and the temperature control equipment needed to be turned on and maintained at a temperature of 45-55 °C, and stirring was required. Inhibit deterioration and rancidity. Another point is that the four-roll rolling mill uses the emulsion to change the liquid, the period is short, and it only takes 1 to 2 months to replace it all. Frequent liquid changes have an impact on production, and the overall cost of using the emulsion is high. Emulsions are improved. Contents of the invention [0003] The purpose of the present invention is to overcome the defec...
