Alkali Resistant Brick for Arc Furnace Definition
 
Alkali resistant fire brick for Arc furnace has the advantages of high load softening temperature, high temperature structure performance and good thermal shock stability, at the same time, Alkali resistant bricks for Arc furnace has the advantages of strong corrosion resistance, easy peeling and wear resistance. Refractory alkali resistant bricks overcomes the shortcomings of poor thermal shock resistance of common high aluminum bricks, low erosion resistance of cement clinker, low softness of phosphoric acid bricks. Firebrick is produced by adding an additive to increase the compressive strength. The alkali resistant fire bricks product has the characteristics of high strength, stable volume, good alkali corrosion resistance. Alkali resistant brick is relatively common in cement kiln preheater, decomposition furnace, tertiary air duct. Alkali resistant bricks are mainly used in open hearth furnaces, oxygen-blowing converters, electric furnaces, non-ferrous metal smelting equipment and glass industries, as well as some high temperature equipment.

Alkali Resistant Brick for Arc Furnace Application
 
1. Ordinary type alkali resistant bricks are mainly used in cement kiln preheaters, decomposition furnaces, and other air ducts.
 
2. High strength alkali resistant bricks are mainly used in cement kiln preheaters, decomposing furnaces, tertiary air ducts, vertical ascending flue, cyclone straight tubes and cones.
 
3. The arch type alkali-resistant brick is mainly used for the cement kiln preheater and the tertiary air duct of the decomposition furnace.
 
4. The heat insulating alkali resistant brick is mainly used for the kiln mouth, kiln door cover and cooling machine of the cement kiln.
 
Alkali Resistant Brick for Arc Furnace Principle of Erosion
 
Alkali fireproof bricks of the mechanism alkali corrosion resistance is that it reacts with metal oxides at high temperatures to form a highly viscous liquid phase, forming a glazed protective layer covering the surface of the brick to block surface pores to prevent penetration and erosion of alkali gold. To the purpose of alkali corrosion resistance.
 
Alkali Resistant Brick for Arc Furnace Transportation Precautions
 
The transportation and storage of alkali resistant bricks must be protected against moisture, so as not to react with water in the air and reduce the performance of alkali resistant fire bricks.
