The composition and basic requirements of the crystallizer assembly
The crystallizer assembly is a key part of the continuous casting machine, and its structural performance directly affects the production and quality of the continuous casting billet. All enterprises are actively exploring according to the actual use of their continuous casting machines, and by optimizing the combination of the parts and components of the crystallizer assembly to meet the ever-increasing demand for continuous casting production.
The crystallizer assembly is mainly composed of the following parts: copper mould tube, outer water jacket, diversion water jacket, upper and lower sealing flanges, various sealing rings, foot roller device, foot roller area spray device. The core part is the copper mould tube, and other parts are assembled around the copper tube.
In order to obtain qualified casting billets, the basic conditions that the crystallizer crystaline assembly should meet are:
(1) It has good thermal conductivity, so that the molten steel can quickly condense and form.
(2) It has good wear resistance to extend the life of the crystallizer , reduce the maintenance workload and the time of replacing the crystallizer , and improve the operation rate of the continuous casting machine.
(3) It has sufficient rigidity, especially in the case of chilling and heating, and a large temperature gradient. Small deformation is required.
(4) The structure is simple, compact, easy to manufacture, easy to disassemble and assemble, and easy to adjust. The cooling water circuit can be connected by itself for quick replacement; the dead weight is small to reduce the inertial force when the mold is vibrating and reduce the drive of the vibration device Power, and make the crystallizer vibrate smoothly.
