Tap Hole Brick Introduction:

Taphole brick is made of high purity fused magnesia and large crystal magnesia, mixed with high purity flake graphite and added with special antioxidant and resin binders,usually shaped by cold isostatic presses. The Tap Hole Brick of converter is one of the most important technical indexes of steel melting, which directly affects the melting period, productivity and slag retaining,therefore affects the quality of steel.Our whole Tap Hole Brick achieve multiple people laying the furnace, improve the speed of laying, shorten the whole laying time, the Tap Hole Brick repair material reduced, and reduce the steel flow to improve the quality of molten steel, reduce the steel process temperature drop, enhance the Tap Hole Brick erosion resistance and mechanical erosion resistance.

Tap Hole Brick Advantages:

1.Tap hole brick is characterized by good oxidation resistance

2.high strength, good corrosion resistance

3.good integrity, easy replacing and long life 

4.Tap hole brick is ideal material taphole of large and medium furnace
Tap Hole Brick Influence：
The taphole life is one of the important indicators of the converter sliding plate slag blocking technology. The taphole is easily damaged due to frequent direct erosion and violent erosion of high-temperature molten steel and high-oxidizing slag, combined with the effects of rapid cold and heat. The length of its life directly affects the converter smelting cycle, steelmaking productivity and slag retaining effect, which in turn affects the quality of steel. The integrity of the tap hole directly controls the amount of slag in the converter, and has a direct impact on the alloy yield and the next refining process.

Measures to improve the application of refractory materials:

1. Improve and optimize the material and structure of the skateboard to greatly increase the service life

2. Measures to improve the overall life of the taphole port during the converter tapping process
