Liaocheng Jin Qing steel pipe advanced production and testing equipment is the necessary guarantee for the manufacture of quality products, so the company attaches great importance to the modernization of production equipment to ensure the leading level in the industry. The production equipment made of foreign advanced technology has high precision, wide range of production specifications and flexible specifications. It is more advanced than the general automatic rail pipe unit, and equipped with advanced automatic control system and online quality inspection system. To ensure the stable and reliable quality of products, precision seamless steel pipe is a kind of high precision steel pipe after cold drawing or hot rolling treatment. Because of internal and external wall seamless steel pipe, no oxide layer has the advantages of precision seamless steel tubes under high pressure without leakage, high precision, Gao Guangjie, cold bending deformation, flaring, flattening without cracks, so precision steel tube, precision seamless steel tube, precision bright tube, precision cold-rolled steel mainly used in the production of pneumatic or hydraulic components of the products, such as cylinder or oil cylinder, are used in precision seamless steel tube.
Precision grinding is the chemical composition of tube carbon C, Si, Mn, silicon manganese, phosphorus, sulfur S P Cr Cr precision grinding tube application to save steel, improve the processing efficiency, have important significance to reduce the machining process or equipment investment, can save costs and working hours, improve the production and utilization of materials at the same time, to improve product quality, reduce the cost, which has important significance to improve economic benefit.
Grinding tube is a through cold drawing or after hot rolling processing of a high precision steel pipe materials. Because the internal and external wall of the precision steel pipe has no oxide layer, it has high pressure, no leakage, high precision, high finish, cold bending, no expansion, flattening, no cracks, etc., so the products mainly used to produce pneumatic or hydraulic components, such as cylinders or cylinders, can be seamless tubes. Chemical composition of grinding tube with carbon C, Si, Mn, silicon manganese, phosphorus, sulfur S P Cr Cr.
The company has grinding tube set 4, production of 30--600 grinding tube (RC tube cylinder tube). The company production of grinding tube (tube model cylinder tube) roughness can reach Ra less than about 0.08 m in diameter, roundness correction, ovality can be less than or equal to 0.01mm, improve the surface hardness, the deformation is eliminated, the hardness increased HV more than 4 degrees, after machining residual stress layer, improve the fatigue strength. 30%, improve the matching quality, reduce wear and prolong the service life of parts.
