Although the stainless steel anti-skid plate has high hardness and anti-rust performance, it may malfunction during use. Therefore, if the stainless steel anti-skid plate purchased by consumers has defects, there is no need to make a fuss. A common failure of stainless steel anti-skid plates is the appearance of white spots due to small cracks on the surface.
Shrinking cavity: The shrinking cavity formed when the molten steel shrinks in the mold is called the shrinking cavity. Lateral cracks: refers to the lateral cracks that appear on the surface of the non-slip stainless steel sheet (usually on the surface of the steel ingot). The depth is usually shallow and can be eliminated by fine grinding. Longitudinal cracks: refers to the longitudinal cracks on the surface of the stainless steel anti-skid plate, usually at the upper part and corners of the steel ingot. The upper part of the crack is very deep, and it is difficult to eliminate it by grinding.
Scarring: On the surface of the stainless steel anti-skid plate, the splashing and adhesion of shell-shaped or spherical metal is called scarring, and the scarring mainly appears on the lower part of the stainless steel anti-skid plate. Thick skin: When the edge of the low-power test piece has irregular dark color and looseness, a large number of oxide inclusions (mainly ferrous oxide) will accumulate around it, which is called overturning.
Net-like structure: The net-like protrusions on the surface of the stainless steel anti-skid plate are called net-like structures. Pits: The pits on the surface of the steel ingot are called pits. Secondary pouring: reconnection marks can be seen around the surface of the stainless steel anti-skid plate. Flash: The metal flakes that exist at the head or tail of the steel ingot and are perpendicular to the surface of the steel ingot are called burrs. Fin: A thin sheet perpendicular to the surface of the stainless steel anti-skid plate is formed on the surface of the steel ingot, which is called a fin.
Bubbles: Bubbles are caused by poor degassing and deoxidation of molten steel or wet raw materials in the molten steel injection system. Defects are usually divided into subcutaneous bubbles and internal bubbles. Prevention method: the molten steel oxidation boiling reduction deoxidation is better, the furnace and all refractory materials in contact with the molten steel should be dry, the tapping trough, prototypes, molds, etc. should be dry, the stainless steel anti-skid plate mold rust spots should be cleaned, and the oil should be thin and even.
