Refractories are generally divided into two types, namely unshaped refractories and shaped refractories. Unshaped refractories are also called castables, which are mixed powdered particles composed of a variety of aggregates or aggregates and one or more binders. They must be mixed with one or more liquids and mixed evenly during use. Strong liquidity. Shaped refractory materials generally refer to refractory bricks, the shape of which has standard rules, and it can also be temporarily processed as needed when building and cutting.
Refractory bricks are generally made of refractory soil. Refractory soil has strong adhesion and refractoriness. Therefore, refractory soil is widely used in refractory masonry. If a high level of fire resistance is required in building fire protection, use Refractory cement masonry, the refractoriness of refractory cement is about 500 degrees higher than that of refractory soil.
