Steel sheet , concrete surfacce , subway surface roughness machine

Product Details

The shot blasting machine was first applied to the removal of surface sticking and oxide scales from cast steel and cast iron castings. Almost all steel castings, ash castings, ma steel parts, and ductile iron parts are shot blasted. This is not only to remove oxide scale and sticky sand on the casting surface, but also is an indispensable preparation process before the quality inspection of the casting. For example, the large gas turbine casing must be strictly shot blasted before the non-destructive inspection to ensure the inspection result. reliability. In general casting production, shot blasting is an indispensable technique for discovering casting surface defects such as subcutaneous pores, slag holes, and sticking, cold septa, and peeling. Surface cleaning of non-ferrous metal castings, such as aluminum alloys, copper alloys, etc., in addition to removing oxide scales and finding surface defects in castings, the more important purpose is to remove shot burrs and obtain decorative surface quality by shot blasting. , get comprehensive results. In the production of metallurgical iron and steel, shot blasting is a technological method for ensuring the combination of mechanical or chemical removal of the phosphors used to obtain high productivity in the mass production of steel. In the production of silicon steel sheets, stainless steel sheets, and other alloy steel sheets and strips, annealing must be performed during the cold rolling process before shot blasting or pickling treatment to ensure the surface roughness and thickness accuracy of the cold rolled steel sheets.
