 How to polish the steel coil

　　1. When the steel coil is polished, mechanical polishing can be used. This method is generally manual, which is to make the uneven position of the steel coil smooth. In the process, props such as sandpaper and oil stone strips will be used to mechanically polish the steel coil. Polishing can improve the quality of the steel coil surface.

　　2. When polishing the steel coil, chemical polishing can also be used. This polishing method uses chemical reactions to smooth the raised position of the steel coil. The biggest advantage is that there is no need to use too complicated Equipment, and the polishing effect is good.

　　3. Electrolytic polishing can also be used for steel coil polishing. Although the principle is very similar to chemical polishing, the polishing effect of electrolytic polishing will be better, because this polishing method uses electrolytic solution to The convex position on the surface of the steel coil becomes flat.

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...
