Grinding on a stainless steel
Grinding is the final finishing of the metal, which is produced on grinding lines. Grind the stainless steel in hot-rolled etched form, in heat-treated cold-rolled etched forms, and also after cold rolling. Depending on the class of the grinding machine, the metal surfaces can be grinded at various levels. Modern grinding lines can carry out two-sided grinding of the surface of stainless steel, while eliminating various defects in the outer layer.
In the process of grinding on the production lines, the upper layers of stainless steel are removed in a qualitative and even manner. Grind rolled metal materials with visible defects in the form of scratches, scuffs, scuffing, shallow captures, and also stainless steel grades, for which improvement of the surface category is necessary. According to GOST 2789, for hot rolled coils of stainless steel that have been processed on a grinding line, the roughness should decrease from the Ra level of 20−10 μm to the Ra level of 1.25−0.63 μm.
With their help they produce grinding of stainless steel. They have abrasive belts with different grain sizes. On the last passages, the graininess of the grinding bands is reduced. Cold-rolled steel in the first passages is ground with belts of reduced grain size.
Carried out before and after polishing the treated strip. The measurement determines the value of the layer of material taken. To obtain the required quality, stainless steel can be subjected to repeated grinding. In many respects, the qualitative level of grinding of stainless steel depends on the correct tension of the metal strip on the line. Well-adjusted machines and the use of additional tools make it possible to increase the quality of work and to reduce the time required for the grinding process.
Grinding with abrasive paper
This abrasive material has a fabric or paper substrate, which is coated with a different grain size. For wet sanding use waterproof skins. Abrasive coatings of skins can be made of corundum, silicon or glass. The surface of products made of stainless steel of complex shape is best liable to grinding with the help of a skin on a linen basis, because during processing it is better adjacent to curved surfaces. The finest grained skins are marked «0» and are used for grinding products from stainless steel at the final stage.
In the warehouse of Electrovek-Steel LLC there is a wide range of high-quality rolled metal of standard and non-standard sizes. We supply stainless steel products in retail and wholesale. All batches of the product have a quality certificate for compliance with the requirements of standards and technical conditions of operation. In the certificate, the manufacturer, the drawing number and the name of the parts, the alloy grade, the mechanical properties of the parts, the chemical composition and the results of additional tests are noted. The implementation of orders — in the shortest possible time. Discounts are given to wholesale buyers.
