How Can We Improve the Corrosion Resistance and Wear Resistance of High-Alumina Castables?
The proportion of high-alumina castables in the lining field of monolithic refractory lining materials is the largest. But in the harsh working atmosphere of the kiln lining, how can we enhance the corrosion resistance of the high-aluminum castable to meet Read More …
Working Conditions of Different Types of Refractory Castables
With the increasing use of refractory castables, there are indeed certain methods and skills on how to choose the material of the castable or what index of castable to choose. This is mainly because the working conditions of different types Read More …
Selection of Al2O3-SiC-C (ASC) Refractory Materials Bonding Agent
Al2O3-SiC-C (ASC) refractory Materials have excellent characteristics such as high strength, strong thermal shock stability, resistance to acid and alkali slag erosion, and good erosion resistance. Therefore, it is widely used as a refractory lining material for blast furnace iron Read More …
Discussion on the Problems of Aluminum Magnesium Castables in Ladle Application
Aluminum Magnesium Castables are a general term for refractory castables with alumina and magnesia as the main components. Broadly called alumina-magnesia refractory castable, generally referred to as alumina-magnesia castable. Application Range of Aluminum Magnesium Castables in Ladle Lining The use Read More …
What is the Relationship Between the Ratio of High Alumina Castables and Indicators
The monolithic refractory material is an inorganic non-metallic material with a refractoriness of 1580℃, which is mainly used in metallurgy, chemical industry, and electric power industry. As a branch of unshaped refractory materials, refractory castables are developing relatively quickly, and Read More …
What is the Ability of Magnesia Bricks to Transfer Heat?
Magnesite brick is an alkaline refractory with a magnesium oxide content of more than 90% and periclase as the main crystal phase. Generally, it can be divided into two categories: sintered magnesia bricks (also called fired magnesia bricks) and chemically Read More …
What are the Wear-Resistant Refractory Materials for CFB Boilers?
At present, wear-resistant refractory materials of circulating fluidized bed boilers in China can be divided into the following three categories according to their functions. (1) Bricks, castables, plastics, and mortar made of wear-resistant refractory materials. (2) Bricks, castables, and mortars Read More …
Servel Kinds of Phosphate Bonded Refractory Castables
Phosphoric acid and acidic oxides hardly react and harden at room temperature. Therefore, it is not suitable as a binder for acidic refractory materials. Phosphoric acid reacts with amphoteric oxides (such as Al2O3) at room temperature to form a hard Read More …
Damage Mechanism and Cause Analysis of Refractory Castable for Water-cooled Beam
Because the working conditions of the refractory castable for water-cooled beams are very bad, the thickness is relatively thin, generally 50-60mm. It is only connected to the water-cooled beam by metal anchoring hooks. Under high-temperature conditions, it is affected by Read More …
