Classification knowledge of Best refractory clay manufacturers

2021-11-30 15:24

Best refractory clay manufacturers refer to clay that can be used as refractory materials with a refractoriness greater than 1580°C and bauxite used as refractory materials. In addition to their high refractoriness, they can maintain volume stability under high temperature conditions, and have slag resistance, resistance to rapid cold and rapid heat, and certain mechanical strength, so they are extremely firm after calcination. Best refractory clay manufacturers are mainly used in the metallurgical industry, as the raw material for the production of shaped refractory materials (bricks of various specifications) and unshaped refractory materials, with an amount of about 70% of all refractory materials. So do you know the classification knowledge of Best refractory clay manufacturers? Let's take a look at it briefly!
Best refractory clay manufacturers are divided into four types: soft clay, semi-soft clay, hard clay and high alumina clay according to plasticity, ore characteristics and industrial use. Soft clay is generally earthy, easy to disperse in water, and can form a plastic mud mass after being mixed with liquid; semi-soft clay has poor dispersibility, and its soaked part can also form a plastic mud mass after being mixed with liquid . These two clays are often used as bonding agents when making refractory products. Hard clay is often in the form of blocks or slabs, and is generally not immersed in water, with high refractoriness, and is the main raw material for refractory products. High alumina clay has high content of Al2O3, high hardness and specific gravity, and high refractoriness. It is often used to make high-grade clay products.
The above is a brief introduction to the classification knowledge of Best refractory clay manufacturers.
