Product Description

Roof of Electric arc furnace Corundum Refractory Casting Preformed Block
The Description:
The prefabricated parts of EAF furnace cover are developed for prolonging the service life of EAF furnace top. There are two kinds of high aluminum and corundum.
The prefabricated parts of the furnace cover are characterized by high temperature resistance, corrosion resistance, no peeling and high softening temperature under load.
The material is divided into high aluminum, corundum, chrome corundum, mullite, etc., with convenient construction and easy installation.
High power electric furnace triangle using high aluminum, mullite, corundum, ultra high power using chrome corundum, corundum.
Up to 500 furnaces are used.
The Physical and Chemical Technial Index Classify:

Chemical composition
Al2O3:≥92%,MgO:<1.0%,СаО:<1.0%,Cr2O3:<2.0%,SiO2:<2.0%
Physical Index
Bulk Density	3.1g/cm3
Cold Crushing Strength	70Mpa
Refractoriness	1700ºC

There are many kinds of refractory prefabricated parts, which can be divided into various types such as high temperature resistance, acid and alkali corrosion resistance, and wear resistance according to different uses. Among them, the high-temperature refractory prefabricated parts are the most widely used, such as tunnel kiln, oil refinery, metallurgical industry, glass industry, power industry, etc., need to use refractory prefabricated parts for heat insulation.
The Feature:

1) Low porosity, low hot-wire expansion rate, good thermal shock stability. Can fully meet the needs of coke oven door;

2) Easy to use, can quickly disassemble the furnace door, reduce the time wasted due to maintenance;

3) Reduce the heat loss caused by the loosely sealed furnace door and save energy:

4) Basically eliminate the air pollution caused by the furnace door is not strict, and achieve environmental protection.
