Casting Mold Powder Features
This kind of mold powder is produced by washed low-carbon graphite as the base material and other fluxes. The casting powder has good lubrication and thermal insulation performance, and can quickly form a three-layer structure after contact with molten steel. It plays the role of lubricating mold wall, preventing secondary oxidation of molten steel and heat preservation of steel ingot head, which has strong adaptation performance and is better than other power plants ash, carbon rock -based, and red mud base type. It can be used for protective casting of steelmaking mould, which is effective in improving the surface quality and tail quality of ingot and prolonging the service life of ingot mold.
Casting Mold Powder Applications
Insulating the molten steel surface of the mould to avoid solidification of molten steel
Insulating air to prevent secondary oxidation of molten steel
Absorbing the inclusions floating in the molten steel, purifying the molten steel
Forming a slag film between the solidified shell and the inner wall of the mould to achieve good lubrication
Improving heat transfer between the mould and the shell to prevent surface cracks.
Usage and dosage
1. The bottom of the steel ingot mold.
2. The amount of mold powder per ton of steel is 1.5-3 kg.
