EAF Taphole Brick(Tap-hole Block)

EAF Taphole brick use low silica,high calcium,high purity fused magnesia sand and large crystal fused magnesia sand as raw material,mixed with big size high purity graphite, added many composite additives like metal and borides. Bonded with thermosetting and thermoplastic phenolic resin.High density,high strength,high purity,good resistance to molten steel mechanical erosion, high temperature resistance and oxidation resistance.

EAF Taphole Brick Introduction:

Taphole brick is molded at isostatic pressing, with fused magnesia and graphite as raw material. It is characterized by good oxidation resistance, high strength, good corrosion resistance, good integrity, easy replacing and long life and it is ideal material taphole of large and medium EAF. Tap-hole bricks are made from fused large crystal magnesite, high purity graphite, powdered metal anti-oxidants and resins. The mono tap-hole blocks are shaped through isostatic pressing and the split tap-hole blocks are shaped through machine pressing.

Tap-hole blocks is generally composed of the outlet block and sleeve brick (also called pipe brick). Tap-hole blocks is covered outside the sleeve brick, which is used to protect the sleeve brick and support the converter brick when the sleeve brick is changed, so as to facilitate the replacement of sleeve brick. Common block brick has pre-formed good finalize the design products, also have the spot with brick directly masonry and become.

We are always to improve the service life of the refractories used in EAF, reduce our customers’ production costs, and improve their profitability. We can design and supply a complete set of refractory materials for EAF, from EAF roof, magnesia carbon bricks for working lining, magnesia bricks for permanent lining, cold ramming mass for EAF bottom, taphole bricks, hot repair mass for EAF.

EAF Taphole Brick Advantages:

Taphole brick is molded at isostatic pressing, with fused magnesia and graphite as raw material. Taphole brick is characterized by good oxidation resistance, high strength, good corrosion resistance, good integrity, easy replacing and long life and it is ideal material taphole of large and medium EAF.

Compared with these steel outlet blocks, split and integral steel outlet blocks can be installed directly after assembling with sleeve bricks in masonry because they are pre-formed, with fewer steel leakage channels and high safety factor. The steel outlet block brick is generally built with working layer brick in the converter shell, and permanent layer magnesite brick is built on site in other places, and filled with ramming material around. The structure is loose, and there are many steel leakage channels, but the cost is relatively low.
