Embodiment 1～12

[0032]Heat the water to 35°C, and add the required amount of lubricant, extreme pressure agent, rust inhibitor, penetrant, pH value regulator, cleaning agent, cleaning aid and defoamer in turn while stirring, and adjust the pH value to 10 ~11, stop stirring and heating after fully stirring for 1.5 hours, filter and fill after standing for 2 hours.

[0033] The specific components and their contents in each composition are shown in Table 2-Table 4. Wherein, the content of each component is the number of parts. In each embodiment, deionized water is used to supplement 100 parts, and the content of component water is omitted.

[0034] In Table 2 to Table 4, EL-20 is castor oil polyoxyethylene 20 ether, EL-30 is castor oil polyoxyethylene 30 ether, HEDTA is sodium diamine triacetic acid, STPP is sodium tripolyphosphate, EDTA-4Na Tetrasodium edetate, EO / PO polyether is ethylene oxide / propylene oxide copolymer, AEO-6 is fatty alcohol polyoxyethylene 6 ether, AEO-9 is fatty alcohol ...

Embodiment 13

[0047] The compositions of [Examples 1 to 12] were diluted with water and used in the rolling lubrication process of cold-rolled steel sheets. When rolling a medium and narrow strip with a minimum rolling thickness greater than 0.4 mm, the dilution concentration is 4% by weight; when rolling a medium and narrow strip with a minimum rolling thickness of less than 0.4 mm, the dilution concentration is 7% by weight. During the rolling process, it is convenient to use, there is no maintenance in the stable state during the use process, and the steel plate is clean after rolling.

Abstract

The invention relates to a water-soluble rolling liquid composition and application thereof. The water-soluble rolling liquid composition mainly solves the problems of low cooling performance of pure oil type rolling liquid and low emulsion stability and low detergency of emulsion type rolling liquid in the prior art. The water-soluble rolling liquid composition comprises the following components by weight: a) 3 to 30 parts of lubricating agent; b) 0.5 to 10 parts of extreme pressure additive; c) 5 to 30 parts of antirusting agent; d) 0.1 to 5 parts of penetrating agent; e) 0.1 to 10 parts of cleaning agent; and f) 15 to 92.3 parts of water. Through the adoption of the technical scheme, the problem is solved well and the water-soluble rolling liquid composition can be applied to the rolling and lubricating procedure of a cold-rolled steel plate.

Description

technical field [0001] The invention relates to a water-soluble rolling liquid composition and its application. Background technique [0002] With the continuous improvement of the cold rolling process, more and more high-speed rolling mills are put into use, so the selection of the cold rolling liquid used in the rolling process is becoming more and more important. Adding rolling fluid between the rolled material and the plastically deformed roll has many benefits, such as reducing friction, reducing wear, obtaining the desired surface finish, etc. When selecting the most suitable rolling liquid, it is necessary to comprehensively consider factors such as rolling process conditions, rolling materials and target product quality requirements. [0003] At present, the common cold rolling fluids are mainly divided into two categories: one is base oil or oily agent, which is directly applied after adding various additives; the other is based on base oil or oily agent. Add vari...
