Key Points for Selecting and Using Lightweight Insulating Refractory Bricks
Lightweight insulating refractory bricks achieve energy conservation and consumption reduction through efficient thermal insulation, and their lightweight characteristics reduce structural load. When selecting lightweight insulating bricks, it is crucial to focus on the operating temperature, ambient atmosphere, and mechanical and chemical corrosion conditions, and to match the brick's material, density, strength, and thermal conductivity accordingly. Correct selection and in
Types of Refractory Materials Used in Different Parts of the Heating Furnace
A heating furnace is a device (industrial furnace) used in the metallurgical industry to heat materials or workpieces (usually metals) to rolling or forging temperatures. It can be divided into continuous heating furnaces and chamber heating furnaces. Heating furnaces are widely used in many industries, including petroleum, chemical, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, and pharm
Materials, Properties, and Applications of High-Alumina Bricks and Magnesia Bricks
Material and Chemical Properties 1. High-alumina bricks belong to the aluminosilicate system, with an Al₂O₃ content of 45%–90%. The matrix is mainly corundum and mullite. Chemically neutral, they can withstand both weak acid and weak alkali corrosion. 2. Magnesia bricks belong to the magnesia system, with MgO ≥ 87%. The main crystalline phase is periclase. Alkaline materials exhibit extremely high inertness to strong alkali slag and iron corrosion, but readily react with a
Advantages of Using Dolomite Bricks Extensively in the High-Temperature Zone of Cement Kilns
Dolomite bricks are primarily composed of dolomite. They are made from a single raw material: sintered dolomite (MgO·CaO). The theoretical composition of the pure raw material is 42% MgO and 58% CaO; the total amount of SiO2, Al2O3, and Fe2O3 is less than 3%. Based on its main components, this brick is prone to hydration. Without waterproofing treatment, dolomite bricks typically decompose into fragments within 2-3 weeks. This presents significant challenges to their use. How
