Refractory Bricks Manufacturing Process

The production process of refractory bricks consists of five parts.

  1. Firstly, crushing. The purpose of this process is to check whether the classification of the particles is clear after the raw material of refractory bricks for sale is crushed, whether the supercritical particles are completely removed, and whether the particle size distribution meets the predetermined requirements.
  2. Secondly, balching. The procedure confirms that the formula and weighing is correct, feeding sequence is in compliance with the regulations, and the type, concentration, and amount of the bonding agent meet the requirements.
  3. Thirdly, pressing. The main point of this step is to check whether forming tool conforms to the type and size specified by the brick types, whether the molding pressure is appropriate, and whether the molding operation is standardized.
  4. Fourth, drying. Drying speed, drying time and drying speed are strictly controlled according to regulations. After drying, check whether the body of refractory bricks is dry and cracked, and if so,  pick it out.
  5. Last but not least, firing. This key step must strictly implement the thermal operation system and  firing system, heating rate, firing atmosphere, holding time, and kiln loading methods.

Refractory Brick Properties

The general properties of refractory bricks for sale include chemical mineral composition, microstructure, mechanical properties, thermal properties, and high temperature use properties. Some of them are measured at room temperature, such as porosity, bulk density, true density, and compressive strength. we can predict refractory bricks status at high temperatures according to these properties, and others are measured at high temperatures, such as refractoriness, thermal shock stability, slag resistance, high temperature volume stability and so on. These features reflect the state in which the refractory brick is at a certain temperature, or the relationship between its interaction with the outside world at that temperature. Refractory bricks usually have the following properties:

  • High Refractoriness
  • Excellent Refractoriness Under Load
  • Volume Stability at High Temperature
  • Good Thermal Shock Resistance
  • Better Corrosion Resistance
  • Good wear-resistance

Classification Of Refractory Bricks For Sale 

Depending on the constituent material, refractory bricks for sale can be classified as below:

  1. Alumina silica fire bricks

Alumina silica brick series consist of high alumina bricks, silica bricks, mullite bricks, corundum bricks and fireclay bricks, etc. All of them are a kind of acid refractory materials containing Al2O3 and SiO2. What’s more, they have good performance in high refractoriness, thermal shock resistance and abrasion resistance and so on.

  1. Magnesia brick series

Magnesia bricks are alkaline products with MgO content of more than 80%. Magnesia bricks generally can be classified into sintered magnesia bricks and chemically bonded magnesia bricks. Magnesia bricks can also be classified magnesia carbon bricks, magnesia chrome and magnesia spinel bricks bricks if further divided.

  1. Insulating fire brick series

Insulating fire brick belongs to a kind of lightweight thermal insulation refractory materials, which is made of high-quality clay as the main raw material through high-temperature sintering. Insulating fire bricks are mainly used for insulating layer of kiln and furnace to prevent the temperature losing. It mainly includes mullite insulation fire bricks, lightweight insulating fire brick, high alumina insulating refractory brick and alumina bubble insulating fire brick,etc.

  1. Acid proof brick

The main component of acid proof bricks is silica, which forms a large amount of mullite under high temperature roasting, which is a substance with high acid resistance. Acid-resistant brick has widely applied in the steel non-ferrous materials, glass chemical industry and chimney flue, such sites.

  1. Series of Alkali-resistant bricks

Alkali-resistant brick is a new type of alkali-resistant clay (or semi-silica) refractory with excellent alkali corrosion resistance. It covers common type alkali-resistant brick, high-strength type alkali proof brick, arch type alkali-resistant brick and insulation type alkali-resistant brick.
