In Mainland China, there are many different types of kilns used in many fields such as crude oil, chemicals, building materials, electricity and machinery. Therefore, the Henan Lite refractory brick products used in the kiln are also various and change according to the specific requirements of the kiln. Heat treatment furnace is the general name of industrial furnace, which performs various metal surface treatments on metal workpieces. The ambient temperature is generally lower than the ambient temperature of the furnace. The heat treatment furnace can also choose various types of electric furnaces, but the furnace and the atmosphere in the furnace must be more strictly controlled.
The ordinary heat treatment furnaces in my country at this stage are made of various refractory insulation materials, heat insulation materials, etc., because the heat treatment furnace must maintain good heat preservation, heat stability, furnace stability, and faster heating speed. , Energy-saving, convenient actual operation and other features.
Henan Lite refractory bricks can be used in hot blast stoves and heating conversion equipment in the iron and steel industry. Refractory bricks have the advantages of high density, high compressive strength, good wear resistance, good corrosion resistance, low thermal expansion coefficient, high grinding efficiency, low noise, long service life, and zero pollution. Refractory brick is a high-quality grinding medium mainly used in various CNC grinders. Refractory bricks are generally divided into two types, namely unshaped refractory insulation materials and special-shaped refractory insulation materials.
The commonly used raw materials of Henan Lite refractory bricks and their application components are simply classified as: clay bricks, used as refractory bricks on the top of the heat treatment furnace, mainly used for the lining of iron-chromium-aluminum resistance wires and the aluminum lining of the controllable vacuum heat treatment furnace High bricks are used for high-temperature furnace linings, electric heating element bricks and salt furnaces; corundum bricks, high-alumina products for bricks, high-temperature furnace electric heating elements, bottom furnaces or furnaces, used for vacuum furnace tubes.
At the same time, Henan Lite refractory bricks are very important raw materials used, which have the actual effect of constructing the entire skeleton of the heat treatment furnace. Therefore, the fire resistance of refractory insulation materials, the continuous high temperature compressive strength and the maintenance of good reliability are also required. The safety factor of refractory insulation materials we mentioned during this period includes three aspects: thermal stability, volume reliability and chemical reliability.
