Corundum Brick High Temperature Resistant Alumina Refractory Brick
Overview
Corundum brick is a high grade alumina based refractory material with an alumina content of over 90 percent. It is made of high purity corundum raw materials through fine grinding high pressure forming and high temperature sintering. Featuring excellent high temperature stability strong mechanical strength and superior chemical inertness corundum brick has become one of the most widely used refractory products for industrial high temperature furnaces.
Key Features
Corundum brick owns outstanding high temperature resistance and can work stably under long term ultra high temperature conditions up to 1800 degrees Celsius. It features ultra high mechanical strength and excellent abrasion resistance, which can effectively resist continuous mechanical friction, material impact and scouring during long term furnace operation. The product also shows great resistance to high temperature oxidation, acidic flue gas and acid slag erosion, maintaining stable chemical performance in complex high temperature atmospheric environments. In addition, it has extremely low thermal creep deformation under constant high temperature load, paired with excellent thermal shock resistance. It can withstand frequent and drastic temperature rises and falls without generating cracks, peeling or structural damage, greatly improving the overall stability and safety of furnace lining operation.
Product Types
According to different production processes and raw materials corundum bricks are divided into multiple common types including sintered corundum bricks fused corundum bricks white corundum bricks and brown corundum bricks. Different types of corundum bricks are available to meet diverse working condition requirements of different industries.
Application Range
Corundum bricks are widely applied in various high temperature industrial kilns and thermal equipment across metallurgy, building materials, chemical industry, electric power and other core industrial fields. They are the preferred lining refractory materials for glass furnaces, rotary cement kilns, ceramic roller kilns and various industrial heating boilers. They also serve as durable and reliable refractory linings for high temperature chemical reaction furnaces, industrial heat treatment furnaces and power plant boiler combustion chambers. Different from basic refractory products, corundum bricks perform excellently in high temperature oxidation, acidic corrosion and weak alkaline working environments. They can effectively resist material erosion and high temperature aging, significantly extend the service life of furnace linings, and ensure long term stable and efficient operation of various industrial high temperature furnaces.
Advantages
Compared with ordinary refractory bricks corundum bricks have higher refractoriness better wear resistance and stronger corrosion resistance. With compact and uniform internal structure they reduce furnace body heat loss and improve overall thermal efficiency. Their reliable performance greatly reduces furnace maintenance frequency and saves production costs for enterprises.
