Refractory brick
Description:
Hard calcium silicate composite brick (Special plate for steel ladle
The product is an inorganic material, with hard calcium silicate as the main crystal phase and stable physical and chemical properties.
The base material of the product is made by autoclaving and hydrothermal synthesis of siliceous and calcareous materials. It is uniformly distributed with a large number of micrometer and nano-scale pores, with a porosity of 77% to 85%, and has excellent thermal insulation performance.
The product is a backing insulation functional material. Due to its performance, it cannot be used as the working layer of the furnace lining.
The product contains no asbestos or other toxic and harmful components. It contains no biological nutrients, will not rot or mold, and poses no risk of pest or rodent damage.
