Abstract

METHOD OF MANUFACTURING TON-SHEET ROLLED STEEL AND TINS, including the operations of cold rolling strip on the mill, supplying lubricant coolant and rolling up the rolled strip into a roll, due to the fact that, in order to improve the quality of the sheet and reduce energy consumption, during the process of winding strips in a roll in interturn. the space is injected with a lubricant-detergent in the form of an aqueous Dyson liquid solution.

Description

The invention relates to the processing of metals by pressure, in particular to the cold rolling of sheet steel coil and tin. The closest in technical essence and the achieved result to the invention is the method of cold rolling of coiled steel sheet, in which an aqueous solution of a detergent, for example, stearox 6 is fed to the last one or two mill stands. However, the known method is characterized by an insufficient decrease in pollution and an increased load on the electric motors of the mill stands up to. The aim of the invention is to improve the quality of the sheet and reduce the progress of electric power. The aim is achieved according to the method of producing sheet steel coil and tin, including the operation of cold rolling the strip on the mill, feeding lubricant cooling means and winding the rolled strip into a coil during winding the strips into the coil are introduced into the intertrench space by a lubricant-detergent in the form of an aqueous solution of Dyson fluid. The drawing shows a scheme for the production of sheet steel and tin sheet steel. The strip 1 is rolled in the work rolls 2 having the support rollers 3 and, through the intermediate roller 4, is wound on a drum 5 of a winder. During the winding process, washing solution 7 is sprayed from the collector to the strip with the formation of an excess of 8 solution. The solution 7 after coiling is left in the gap between the coils 9, The method is carried out on the five-blade and reversing mills 1200 during cold rolling, more. tons of sheet steel grade EZ thickness of 0.33-06 mm. The strips of rolled steel rolled into coils at the same time as a CV feed into the interturn space of an aqueous solution of a 1-2% concentration of DiSon lubricant. After removing the coils from the coilers, they were kept in the warehouse for 1-3 days, and then received for subsequent technological operations. After processing the strips on the brushing machine: samples were taken from batches of finished sheets to control the quality of the n (3 surfaces. The control showed that the surface of the sheets and strips is distinguished by high purity and gloss, and also has a uniform texture. The surface roughness corresponded to the ninth class according to GOST 2789- 73. The destructive method makes it possible to reduce the contamination of cold-rolled transformer steel by 2.7-3 times, improve uniformity and improve surface quality, increase the output of higher grades of finished transformer sheets It became 13%.
