[0002] The crystallizer is a very important part of the continuous casting machine. It is a cylindrical tank container with forced water cooling. The wall of the crystallizer is equipped with a jacket or a coil is installed inside the crystallizer to heat or cool the solution in the tank. The crystallizer usually needs to use a protective device when in use. The protective device includes an argon protective device and a dust cover. The argon protective device can prevent the loss of oxygen and easily oxidized elements in the billet, and the dust cover can prevent dust from entering the crystallizer and affecting the quality of the billet.

[0003] In order to prevent the loss of oxygenated and easily oxidizable elements in the steel billet and dust from entering the crystallizer to affect the quality of the steel billet, the prior art generally adopts a method of sleeve-mounting an argon protection device penetrating the upper and lower ends on the top of the crystallizer, thereby forming an argon protection on the top of the crystallizer, and then setting a protective cover on the argon protection device to prevent dust from entering the crystallizer. However, since the argon protection device and the dust cover are both heavy and the crystallizer is relatively high, the installation of the argon protection device and the dust cover becomes very difficult.
