Method for compounding concentration of emulsion used for rolling mill and compounding device

Abstract

The invention relates to a method for compounding concentration of emulsion used for a rolling mill, wherein the process of adopting crude oil to prepare the emulsion is realized by flow-controlled adding process of crude oil and the process of adopting desalted water to prepare the emulsion is realized by flow-controlled adding process of desalted water. The crude oil is transferred to an emulsion main tank from a crude oil tank through a dispensing pump and a flow meter is adopted to monitor flow data of the crude oil and the flow data is sent to a control processing unit; and the desalted water is transferred to the emulsion main tank from a desalted water tank through a desalted-water pump and a flow meter is adopted to monitor the flow data of the desalted water and the flow data is sent to a control processing unit. The compounding device comprises the crude-oil tank, the dispensing pump, the desalted water tank, the desalted water pump, the emulsion main tank, two flow meters and two control processing units. With the invention, the concentration of the emulsion can be easily controlled and the precision is high; the operation is simple, convenient and feasible and the maintenance is convenient; both contamination and waste can be reduced; the manufacturing cost can be reduced; and the lubricating effect of the emulsion is good and the service life of rollers can be prolonged.

Description

technical field [0001] The invention relates to the field of cooling and lubricating systems for metallurgical equipment, in particular to a method and a preparation device for preparing the concentration of emulsion in a rolling mill. Background technique [0002] At present, the emulsion is generally used as the cooling and lubricant of the continuous rolling mill to cool and lubricate the strip and rolls; the emulsion also has the functions of energy saving, cleaning, rust prevention, and shape control. The high-quality emulsion has a good cooling effect, which can take away the heat generated in the rolling process in time, and obtain better plate shape control; its good lubricating effect can better lubricate the roll and reduce the rolling force. Reduced roll wear, thus extending service life and saving electricity. [0003] The emulsion is made of crude oil and desalinated water. Different rolling products and specifications require different emulsion concentrations,...
