We all know that refractory bricks are made of special materials. Normal bricks cannot withstand very high temperatures. Therefore, it is necessary to use such high-strength, high-temperature resistant materials as masonry for various industrial furnaces. In industrial production, almost all high-temperature furnaces require refractory bricks. Such as glassworks, iron making, steel making, refining furnace, electric furnace, drying equipment, muffle furnace, etc.
Rongsheng Refractory Bricks For Sale – for Industrial Thermal Furnaces. Refractory bricks for white ash kiln are relatively simple. Due to its low calcination temperature requirements, the maximum temperature does not exceed 1300 ℃. Therefore, the refractory brick lining used is generally high alumina refractory bricks. Lightweight insulation bricks can be used for the heat insulation layer. The brick thickness of the white-ash shaft kiln is relatively large. The thickness of 250m3 white-ash shaft kiln bricks can reach 1000mm. The brick thickness of the rotary kiln is only about 200mm. In addition, refractory concrete can also be used. In recent years, special high-alumina refractory bricks have also been used in the calcination zone of shaft kilns, such as abrasion-resistant high-alumina refractory bricks.
The size of refractory brick is usually adopted the standard type whose type is 230 *114* 65. The price of refractory bricks for sale varies according to its type, with ordinary clay refractory bricks for sale at a lower price and magnesia carbon bricks being the most expensive. You must buy the refractory bricks satisfying all your needs at a competitive price in RS factory. Click for more details.
The production process of refractory bricks consists of five parts.
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.
Secondly, balching. The procedure confirms that the formula and weighing is correct, the feeding sequence is in compliance with the regulations, and the type, concentration, and amount of the bonding agent meet the requirements.
Thirdly, pressing. The main point of this step is to check whether the 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.
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.
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.

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.
High Alumina Refractory Bricks
Refractory bricks usually have the following properties
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.
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.
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.
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.
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.
