MgO Magnesia Crucibles for Melting Steel

The crucible is widely used in industries such as non-ferrous metals, aviation, precision casting, and high-energy magnetic materials. It is an ideal melting container for steel in medium frequency furnaces and high-frequency induction furnaces.

Capacity: 0.2kg-300kg

Material: There are high-purity fused magnesia and high-purity fused synthetic magnesium aluminum spinel.

Due to its high temperature, smooth inner working surface, and good resistance to erosion and peeling, this crucible can improve the purity of molten steel and reduce the inclusion rate of products. Therefore, it is an ideal melting container for high-precision products such as high-temperature alloy precision casting.
