Continuous Casting Mould Powders – IspatGuru

 · This mould powder forms a layer having a total depth of 100 mm to 150 mm. Due to the high temperature of the liquid steel, well above the melting point of the powder, a temperature gradient forms in the vertical direction through the powder. On the top there is the newly added mould powder, forming a powder layer.

Borosilicate glass

Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass. Such glass is subjected to less thermal stress and can withstand temperature differentials ...
