Precision ring

Use intelligent controlled atmosphere roller type quenching and tempering automatic production line, adopt electric heating, quenching in enclosed nitrate quenching tank. Nitrate cleaning liquid can be reused after separating by salt water separator. This is green production without salt emissions. The whole line is automatic controlled by computer, the cooling speed of salt bath is adjustable, with good harden ability, good surface quality, small deformation. It is suitable for thin and large bearing rings heat treatment. The product quality is stable, with low energy consummation, no pollution and high production efficiency. Use intelligent controlled atmosphere net belt quenching and tempering automatic production line, suitable for the martensitic quenching for small and medium-sized bearing ring with large quantities. The protection atmosphere in quenching furnace is controlled by computer. The products have no decarburization and good surface quality. This line suit for different heat treatment requirement by adjusting the heat treatment parameters and have high production efficiency. Its had regular form, high precision and geometric accuracy, low allowance and tolerance, high material usage. It can save material above 10%. The good quality can improve the usage life.
