Problems solved by technology

Its disadvantages are: 1) Milling hundreds of bosses on the back side of the copper plate, the processing difficulty and cost can be imagined. When it is important, the platform needs to be processed into a streamlined structure, which is very difficult to process, and the entire copper plate Milling, milling off a lot of copper wastes a lot of raw materials, copper materials are expensive to process and the cost of preparing mold copper plates is extremely high
2) After the crystallizer copper plate reaches the service life, it needs to be replaced with a new mold copper plate. It is necessary to take out hundreds of bolts from the boss, and it is necessary to process the new copper plate into a copper plate with several bosses on the back. Boss needs to be processed, and the processing cost is extremely high
3) Although setting the boss on the copper plate can increase the contact depth between the inner thread of the boss and the bolt, but if a larger screw hole is set in the boss, a thin wall will be formed around the boss and the connection will not be firm. If you want to increase the bolt and The firmness of the screw hole can only be reduced by reducing the thread diameter of the boss, but the reduction of the bolt diameter also cannot achieve the required firmness. We can only set more bosses on the copper plate, and setting more bosses will reduce the The contact area between the copper plate and water reduces the cooling performance

Description

technical field [0001] The invention relates to the field of metallurgical continuous casting equipment, in particular to a liquid-cooled crystallizer for convenient metal continuous casting. Background technique [0002] The crystallizer in the prior art, such as a liquid-cooled crystallizer disclosed in CN03127762.4 for metal continuous casting, comprises a crystallizer plate (1) of copper or copper alloy, which is connected with an adapter plate by means of fixing bolts (14) or water tank connection. The crystallizer is characterized in that the fixing bolts (14) are fixed on a platform (7) protruding from the mold plate (1) on the coolant side (6), the platform at least partly protrudes between the crystallizer plate (1) and The coolant gap formed between the adapter plate or the water tank has a streamlined shape adapted to the coolant flow direction (S). The advantage is that the crystallizer plate is supported on the adjacent adapter plate or the adjacent water tank...
