interpret the technology of refined copper water jacket used in continuous casting
The uniformity of the gap between the water jacket and the crystallizer is very important, and it is absolutely necessary to ensure that precise tolerances are maintained between the external dimensions of the copper pipe and the internal dimensions of the water jacket during production.In order to solve the problem of the shape and size precision control of the water jacket cavity, the copper pipes used in large quantities in steel mills are almost all produced by extrusion molding technology, and the control of the copper pipe, shape and size has reached very high precision.If copper pipe production technology can be used to produce water jackets, this problem is easy to handle.
Without welding, but with a simple pure mechanical processing and general mechanical assembly method, can complete the connection problem between the flange and copper jacket, this is refined copper jacket technology, is China's independent intellectual property rights.This technology has been successfully applied in the continuous casting production of Xuansteel, Pusteel, Chengsteel, Jiusteel and other steel mills, and is also the national patent technology of MCC continuous casting company.
Because this is a major part of the continuous caster crystallizer, known as the "heart" of continuous casting equipment, through this technology can effectively solve the problem of multiple, traditional manufacture technology for extrusion forming, because the forming mechanism of pipe strain characteristics is not consistent, make its appearance, dimensional accuracy, and hardness are difficult to reach out and efficient use of scale。
