Customized Intermediate Manufacturing Process Vessel Crystallizer Manufacturer

To prevent molten steel from sticking to the inner wall of the mold during condensation, reduce friction resistance during billet drawing, improve the surface quality of the billet, and extend the service life of the mold, lubrication of the inner wall of the mold is also necessary in production. Lubrication is the use of liquid lubricants or protective slag with a boiling point higher than the temperature of the inner wall of the mold (about 200 ℃). During the vibration process of the mold, they are continuously brought into the inner wall below the steel liquid level and form an oil gas film or slag film between the steel or billet shell and the inner wall of the mold to lubricate the inner wall.
