Thermite Welding Supplies: Crucible Lining
are sintered in very high temperature, so it should be protected from any moisture at all time, otherwise it may cause failure when welding.
Crucible Lining Description
Crucible liner technical specifications
1. Magnesia crucible liner matches UIC60 rail thermal conductivity part.
2. Crucible liner MgO >96%.
3. Service life more than 30 hot melt welding joints, which depends on the welding operator.
4. Magnesia crucible liner bottom hole diameter is 32mm, due to heating process, tolerance ±0.5mm is allowed.
5. The crucible is sintered at a very high temperature, so it should always be protected from moisture, otherwise it may lead to welding failure.
6. The physicochemical analysis of the magnesia crucible liner is as follows.
