How to effectively prevent crucible corrosion (as shown in figure)?

Longhua technology reminds you:

1, as far as possible to the furnace slag to slag outside the furnace, such operation is to reduce the probability of crucible corrosion;The other is to save the slag refining process and the incubation waiting time after the end.（www.longhuamachine.com/www.diecastingmachinechina.com）

2.Choose the solvent with low content of sodium and chlorine when removing slag, refining, deterioration and covering.Crucible is porous, sodium, chlorine will accelerate the corrosion of the pores to form holes.（www.longhuamachine.com/www.diecastingmachinechina.com）

3.The temperature of slag removal and refining aluminum solution should reach 720 ~ 730℃, because if the temperature is not enough, the solvent cannot react quickly and will be absorbed on the inner wall of the crucible, accelerating the corrosion of the crucible.（www.longhuamachine.com/www.diecastingmachinechina.com）

4. Timely clean the slag on the walls and bottom of the crucible. First, the expansion rate of the slag is larger than that of the crucible when the slag is too thick and the temperature rises, which will lead to the cracking of the crucible;Second, the solvent adsorption or precipitation on the residue of the crucible will accelerate the corrosion of the crucible;Third, please clean in the high temperature phase to prevent physical damage to the crucible.（www.longhuamachine.com/www.diecastingmachinechina.com）
