According to the characteristics of the steel industry, the best insulation material should meetthe three conditions of high temperature resistance, low high temperature thermal conductivityand low space occupancy. (eramic fiber products can perfectly meet the insulation needs of thesteel industry with low high temperature thermal conductivity, strong thermal shock resistancelight weight and easy cutting characteristics.Ceramic fiber products are widely used in the steel field, They can be used for kiln backinginsulation and as ladles, They play a role in heat insulation in heating furnaces, continuousannealing furnaces, galvanizing lines, kiln cars and other equipment in the steel industry.
