Problems solved by technology

[0003] At present, there are two main types of rolling oils for cold-rolled ultra-thin plates on the market: one is rolling oil based on natural animal and vegetable esters. This product has good lubricity, but poor detergency
Unable to achieve the requirement of bright annealing without degreasing treatment
It is suitable for high-load and high-speed rolling, with good lubrication, but the problem is that it is poor in cleanliness, and the rolling mill system is prone to a large amount of sediment, which pollutes the environment and affects appearance and work efficiency.
The cleanliness of annealing is poor, and the finished board with excellent surface quality cannot be obtained
The other type is rolling oil based on mineral oil. This product has excellent detergency and can be annealed directly without degreasing. Can not meet the rolling requirements under high pressure and high speed conditions

Abstract

The invention provides a rolling oil for a cold-rolled ultra-thin sheet. The rolling oil comprises, by weight, 75% to 82% of synthetic ester, 4% to 8% of a surfactant compound, 1.5% to 4% of a phosphide anti-wear agent compound, 7.5% to 15% of a sulfide extreme-pressure antifriction agent compound, 0.75% to 1.25% of a metal deactivator and 0.25 % to 0.75% of an anti-rust agent. The invention also provides a preparation method for the rolling oil applicable to the cold-rolled ultra-thin sheet. Compared with the prior art, the rolling oil provided by the invention has the advantage of capacity of improving lubricity, annealing detergence and detergency and reducing cost.

Description

technical field [0001] The invention relates to the field of rolling oil, in particular to a rolling oil applied to cold-rolled ultra-thin plates and a preparation method thereof. Background technique [0002] As the demand for extremely thin plates (thickness 0.12-0.18mm) in the cold rolling industry is increasing, the requirements for the surface quality of cold rolled sheets are becoming more and more stringent. With the rapid development of cold-rolling equipment and related technologies, the production of cold-rolled sheets is now high-speed and large-scale. This puts forward higher requirements on the lubricity, detergency, annealing detergency, stability and other properties of rolling oil. [0003] At present, there are two main types of cold-rolled thin plate rolling oils on the market: one is the rolling oil based on natural animal and vegetable esters. This product has good lubricity, but poor detergency. The requirement of bright annealing without degreasing tr...
