The role of casting coke in the pouring process
Reduce inclusions and porosity
Inclusions and porosity are common problems in the foundry industry, which can reduce the strength and toughness of castings and affect the density and quality of castings. Casting coke can be used to reduce inclusions and porosity by reducing ash, sulfur content, volatile matter, etc.
Improve the effect of metal liquid deoxidation
There are some unstable elements in the metal liquid, such as carbon, sulfur, phosphorus, etc., which are easy to react with the oxygen in the air to produce oxides. Casting coke can improve the effect of metal liquid deoxidation and reduce the content of unstable elements.
Maintaining temperature
In the casting process, in order to ensure fluidity needs to maintain a certain temperature of the metal liquid. Casting coke has good thermal conductivity, can maintain the temperature of the metal liquid in the casting process.
