Continuous casting machine is an important metallurgical equipment widely used in industries such as steel and non-ferrous metals. The normal operation of the continuous casting machine cannot be separated from the support and guarantee of various accessories. Next, let's learn about the relevant knowledge of continuous casting machine accessories.
Firstly, the most important type of continuous casting machine accessories is the crystallizer. The crystallizer is the core component of the continuous casting machine, playing a direct role in affecting the quality of the billet. It is composed of crystallizer shell, crystallizer lining, crystallizer water jacket, etc. The shell of the crystallizer is generally made of stainless steel material, which has the characteristics of high temperature resistance and corrosion resistance, and can withstand work in high-temperature and high-pressure environments. The lining of the crystallizer is generally made of refractory materials, which can effectively prevent the wear of the inner wall of the crystallizer. The crystallizer water jacket is cooled by circulating water to maintain the temperature of the crystallizer and ensure the cooling effect of the billet.
Secondly, another important component in the accessories of the continuous casting machine is the tension leveler. A tension straightening machine is a device used to pull the casting billet out of the mold and perform tension straightening. It consists of components such as a tension straightening mechanism, tension straightening roller group, tension straightening roller bearings, etc. The tension and straightening mechanism is generally driven by hydraulic pressure, which can provide sufficient tension to ensure the pulling out and straightening process of the casting billet. The tension straightening roller group uses a combination of multiple rollers to achieve uniform tensile force on the casting billet and avoid local deformation. The tension roller bearing is a key component that bears the gravity and working force of the roller, and needs to have good wear and corrosion resistance.
In addition to the crystallizer and straightening machine, there are many other important components in the accessories of the continuous casting machine. For example, a pouring mechanism is used to separate the slag from the billet, ensuring the quality of the billet; Positioner, used to accurately locate the casting billet, enabling the continuous casting machine to work stably; The billet changing mechanism is used to remove the solidified billet from the mold and prepare for the next continuous casting.
The quality and performance of continuous casting machine accessories are directly related to the operation effect and product quality of the continuous casting machine. Therefore, when selecting accessories, attention must be paid to their material, process, and manufacturing process selection. Generally speaking, accessories should have properties such as high temperature resistance, wear resistance, corrosion resistance, and be able to adapt to the high-temperature and high-pressure working environment of continuous casting machines. In addition, it should also have good dimensional accuracy and surface quality to ensure the assembly and use effect of accessories.
In short, the accessories of the continuous casting machine are essential components for the normal operation of the machine, which directly affect the working effect and product quality of the machine. When selecting accessories, attention must be paid to their quality and performance to ensure that they can adapt to high-temperature and high-pressure working environments, and have good dimensional accuracy and surface quality. Only in this way can the normal operation of the continuous casting machine and high-quality product output be guaranteed.
