Introduction of Mullite Refractory Brick Types and Characteristics

Mullite refractory bricks are made of synthetic mullite, according to the specific gravity of the product requirements, adding organic compound fillers, vacuum extrusion molding, high temperature sintering synthesis of lightweight mullite products. With its characteristics of light weight and excellent thermal insulation performance, mullite lightweight refractory bricks are widely used in the hot surface refractory lining or insulation layer of a variety of thermal equipment, creating conditions for improving the energy efficiency of the equipment.

The choice and price of refractory bricks | Technology Frontiers

When choosing refractory bricks, if you pay too much attention to the price of refractory bricks, you will enter a misunderstanding. When choosing a product, it is necessary to consider the use, use effect, quality, use time, etc., and then the price. If you choose a product without quality assurance because of the price problem, this may cause unnecessary losses.

Why can refractory brick fire?

Refractory brick is an inorganic non-metallic material with a refractoriness of not less than 1580 ℃. It is the basic material for high-temperature technology, the structural material for thermal equipment such as masonry kilns, and the functional material for manufacturing some high-temperature containers and components or for special functions.

The firing process of refractory bricks

The development of a reasonable kiln loading map is a prerequisite to ensure the quality of the kiln, but if the kiln loading operation is improper, it will also reduce the qualified rate of the shape of the fired products. Therefore, in the production of refractory materials, the basic requirement for the quality of the kiln is to ensure that the bricks are flat, stable and straight, and to avoid bonding between the bricks due to high temperature firing, and to reduce the distortion of the fired products. In order to achieve the above requirements, the kiln is usually filled with a layer of sand with a grain size of 0.5~3mm evenly between each layer of bricks. Products of different nature have different requirements for sand filling in kilns. Usually clay bricks and high alumina bricks use silica sand, bauxite chips, rice husk or rice husk ash. Silica brick uses waste silica brick sand or silica sand; Magnesia brick uses magnesia sand or chrome ore sand.

Another use of waste refractory bricks

Heat-resistant concrete is a kind of special concrete that can withstand high temperature for a long time (above 200 ℃) and maintain the required physical and mechanical properties under high temperature. The heat-resistant concrete used in the lining of industrial kilns instead of refractory bricks is also called Refractory concrete. The cement used in this test is aluminate cement, because the chemical composition of the cement contains more Al₂ O₂, which has a higher sintering strength and refractoriness after sintering at about 1000 ℃ to produce ceramic bonding.
