When using continuous casting equipment, the most fearful thing is that some accidents occur. This is a kind of damage to the operation process, equipment quality and personnel safety. When the flow rate of the cooling water around the outer wall is uneven, it is easy to happen. At that time, it is necessary to use refined copper water jacket technology.
Refined copper water jacket technology:
The uniformity of the gap between the water jacket and the mold is very important. During production, it is absolutely necessary to ensure that the external dimensions of the copper pipe and the internal dimensions of the water jacket maintain a precise tolerance. In order to solve the problem of precision control of the shape and size of the inner cavity of the water jacket, almost all of the copper pipes currently used in steel mills are produced by extrusion molding technology, and the control of the inner, shape and size of the copper pipe has reached very high precision. If the copper pipe production technology can be used to produce the water jacket, this problem will be easy to handle.
No need for welding, but simple pure machining and general mechanical assembly methods can complete the connection problem between the flange and the copper water jacket. This is the refined copper water jacket technology, which is my country's independent intellectual property rights. This technology has been successfully applied in the continuous casting production of steel plants such as Xuanshan Iron and Steel, Pudong Iron and Steel, Chenggang, Jiuquan Iron and Steel, and it is also the national patent technology of China Metallurgical Continuous Casting Company.
Because this mold is the main component of the continuous casting machine, it is called the "heart" of the continuous casting equipment. This technology can effectively solve multiple problems. The traditional manufacturing process is extrusion molding, because the forming mechanism does not match the tube billet. The strain characteristics make it difficult for the shape, dimensional accuracy, and internal and external hardness to reach the high-efficiency application scale.

In continuous casting, low corrosion resistance often occurs, which directly leads to uneven composition and will eventually affect the smelting quality. In or
