1,Product description:
The tundish gunning material produced by magnesia sand and olivine sand plus a variety of additives has superior performance. It is a heat hardening or gas hardening refractory with strong adhesion. It can obtain a thicker gunning layer with high density, low rebound rate and good application effect.
The tundish gunning material produced by our company has the following characteristics
1) it can resist the thermal stress generated in the tundish system
2) the linear change rate is positive and has crack self-healing performance,
3) the lining body surface is smooth and conducive to the stripping of the working layer
4) it has strong corrosion resistance
5) comprehensive masonry of the tundish lining can effectively improve the service life of the tundish
