Embodiment Construction

[0031] The preparation method of cold rolling emulsion of the present invention mainly comprises the steps:

[0032] (1) Dissolving the emulsifier in the regenerated lubricating oil to obtain an oil phase;

[0033] (2) Dissolving other surfactants such as bactericides in water to obtain an aqueous phase;

[0034] (3) Fully mix the oil phase and the water phase (for example, at a stirring speed of 500-900 rpm) with a mass ratio of X:(100-X) (mixing time is 60-120 minutes, preferably 100 minutes) to A cold rolling emulsion is obtained, wherein X is between 48-60, preferably between 52-54.

[0035] The raw material oil used in the present invention comes from the waste lubricating oil produced by Baosteel’s cold rolling process. Since the waste lubricating oil contains impurities such as metal and oil sludge, it must undergo a series of physical and chemical removal of impurities, and then be obtained by molecular distillation. Regenerated lubricating oil with the physical para...

Abstract

The invention provides a cold-rolling emulsion and a preparation method thereof. The cold-rolling emulsion comprises an oil phase and a water phase which are sufficiently mixed, wherein the oil phase comprises reclaimed lubricating oil and an emulsifying agent accounting for 4-8% of the mass percentage of the cold-rolling emulsion, and the hydrophilic-lipophilic balance value of the emulsifying agent is 3.5-5; the water phase comprises water and a bactericide accounting for 0.3-1% of the mass percentage of the cold-rolling emulsion; the mass ratio of the oil phase to the water phase is X: (100-X), wherein X ranges from 48 to 60. According to the invention, the reclaimed lubricating oil is used as a raw material which is mixed according to a proper oil-to-water ratio, and proper surfactants such as the emulsifying agent, the bactericide and the like are added, so that the cold-rolling emulsion with favorable stability, friction performance, annealing detergency and rheological property is obtained, the quality of the cold-rolling emulsion is ensured, meanwhile, the production cost is greatly reduced, the energy is saved, and the loss is reduced.

Description

technical field [0001] The invention relates to a cold rolling emulsion and a preparation method thereof. Background technique [0002] Cold rolling emulsion is a stable emulsion produced by emulsifying mineral oil, emulsifier and other surfactants through a series of process conditions. It has good lubricating properties and can reduce rolling pressure when used in steel cold rolling. Reduce rolling energy consumption and roll consumption, cool rolls and strips, and control strip shape. Compared with rolling oil, cold rolling emulsion has good surface cleanliness after rolling and annealing. The rolling process lubrication technology meets the needs of energy saving, clean production, and product quality improvement in the current steel rolling production through the above functions of the cold rolling emulsion. [0003] With the continuous development of the steel sheet market, people's requirements for the quality of the sheet are improving, so the market for cold-rolled...
