Embodiment Construction
[0021] The present invention will be further described below in conjunction with accompanying drawing of description and specific embodiment:
[0022] A method for improving the surface cleanliness of cold-rolled steel strips in the present invention uses a chemical agent to clean the upper and lower surfaces of the steel strip. %, 1-3% of hydroxyethylidene diphosphonic acid, and 1-2% of polyoxyethylene nonionic surfactant, the above values are volume percentages.
[0023] One achievable way is to dip the chemical agent into the absorbent cotton and then contact the surface of the steel strip to generate relative motion, so as to clean the surface of the steel strip.
[0024] Another achievable way is: after spraying the chemical agent on the surface of the steel strip, use absorbent cotton to contact with the surface of the steel strip and generate relative motion, so as to clean the surface of the steel strip.
[0025] Such as figure 1 , figure 2 As shown, a special eq...
