 Surface treatment process of medium-thick carbon steel plate

　　In the manufacturing industry of many professional mechanical equipment and large structural parts, carbon steel plates are widely used. For example, in engineering, energy, and mining machinery industries, many products use steel plates with a thickness of 6-20mm. Hollow flat sheet, and most of them are sheet with a porosity of 30%. And so on. After these carbon steel plates are cut by plasma cutting or oxygen cutting, various flashes, slag and burrs are left on the cutting edge. These slag and burrs must be removed (Figure 1), and the sharp edges must also be removed Rounded corners.

图片
Introduction to 20 # carbon steel plate       20 # belongs to superior carbon steel, which complies with GB/T711 standard. 20% of 20 # steel refers to carbon content, which is 0.2%, belonging to low carbon steel. Steel can be divided into low carbon steel, medium carbon steel and high carbon steel. Mild steel - carbon content is generally less than 0.25%; Medium carbon steel - carbon content is generally between 0.25 and 0.60%; High carbon steel - carbon content is generally greater than 0.60%. 　　Domestic and international correspondence of 20 # steel plate: refer to the corresponding steel grade: China's GB/JB standard steel grade is 20, China's Taiwan CNS standard steel grade S20C, Germany's DIN standard material number 1.0402, Germany's DIN standard steel grade CK22/C22. British BS standard steel grade IC22, French AFNOR standard steel grade CC20, French NF standard steel grade C22, Italian UNI standard steel grade C20/C21, Belgian NBN standard steel grade C25-1, Swe...
