Characteristics of steel grit: moderate hardness, strong toughness, impact resistance, can be used repeatedly for several times in a row, long life, good rebound, strong adhesion, fast cleaning speed, low sand consumption, no breakage, high brightness of the cleaned workpiece, and good technical effect.
Shape: angular gray-brown or light blue granular, specification range: 0.2mm-4.0mm.
Raw materials: scrap iron + iron alloy, composition: carbon 0.85-1.20%, silicon ≥0.40%, manganese 0.60-1.20%, sulfur ≤0.05%, phosphorus ≤0.050%, the remaining main components are iron,
Purpose: Used for sand cleaning, rust removal, oxide scale surface cleaning, etc.
Processing technology: The raw materials are melted into a liquid state through an electric furnace. After special treatment such as atomization, the product is shaped into a sphere. It is then dried, dusted, and screened. After screening, the spheres with a diameter of over 2.0 mm are professionally ground into mixed types of various particle sizes through crushing equipment. The angular steel grit is then screened to produce steel grit products of various specifications, followed by heat treatment, finally drying, screening and packaging.
