Converter and electric furnace gunning materials have the characteristics of high adhesion rate and good corrosion resistance at high temperature, especially in rotating furnaces.
Furnace, electric furnace later use effect is better. This product can be carried out in the furnace temperature between 300~1700C
For gunning, the amount of water added is generally about 15%, and it can also be adjusted according to the furnace temperature to achieve satisfaction
use effect. In the process of transportation and storage, attention should be paid to moisture-proof, so as not to agglomerate and affect the use effect.
The fruit has a shelf life of two months.

Converter and electric furnace gunning material construction requirements
1. Dry gunning is used, and water is added to the gun head.
2. Air pressure 5-8kg/cm, water pressure 4-5kg/cm.
3. When spraying, the distance between the gun head and the surface of the construction body should be kept 0.8-1m.
4. The thickness of one shot should not be greater than 30-50mm.
5. This material is suitable for hot repair of various converter furnace trees
The unshaped refractory material used when repairing the lining of thermal equipment by spray construction method is called refractory gunning material. It is made of a refractory set with a certain particle gradation
Acid resistant refractory gunning material is used for spraying of blast furnaces, hot blast stoves, hot blast pipes, flue protection layers, working layers, etc.
In the blast furnace smelting process, blast furnace taphole clay, as a key plastic material, plays a vital role. This article will introduce in detail the product characteristics, working principle and innovation of blast furnace taphole clay in improving furnace stability and production efficiency.
Special Acid-proof Brick
Lightweight acid-proof Brick
Acid resistant brick is the ideal choose for your project with their features of proof pressure, corrosion resistance, easy to clean and acid-base resistance.
Anchor bricks are anchor bricks for industrial kilns. The electric furnace roof is a furnace roof structure supported by metal hanging bricks and refractory bricks. Therefore, the leakage of reactive gas and hot gas in the furnace will damage the metal hanging parts, thereby causing furnace damage. roof collapse accident. Anchor bricks are also called hanging bricks and anchors.
The high-alumina bricks are mainly used in the regenerator of the hot blast stove. The lattice bricks with a certain structure are arranged in an orderly manner, and the upper and lower through holes of the lattice bricks can allow the gas to pass through.
