What is the difference between clay refractory brick and high alumina refractory brick
First, there is a difference in the material, one is clay, one is high aluminum.
Clay tiles, also known as sintered refractory brick, are man-made small blocks for construction. The fireclay refractories are made of clay (including shale, coal gangue and other powder) as the main raw material. They are processed, formed, dried and roasted. Solid and hollow respectively.
alumina brick is a kind of refractory, the main component of this refractory brick is AL2O3.
Alumina content of 48% or more of a neutral Refractory company refractory material. From bauxite or other alumina content of the higher raw materials formed and calcined. High thermal stability, refractoriness above 1770 ℃. Slag resistance is good for masonry electric furnace, glass melting furnace, cement rotary furnace lining.
High load and soft creep high alumina brick [1] is a high grade refractory made of superfine bauxite, fused corundum and fused mullite as the main raw material. The product has high-temperature creep, corrosion resistance, thermal shock stability, etc., suitable for large and medium-sized hot stove.

Aluminum Carbon Long Nozzle (Ladle Shroud)
 |
Aluminum Carbon Long Nozzle (Ladle Shroud) |
Introduction
Based on function categories, Changxing Refractory aluminium carbon long nozzles(also called Ladle Shroud, Long Nozzle) can be classified into preheating refractory nozzle, non-preheating refractory nozzle, argon blowing nozzle and not argon blowing nozzle; and according to material quality, ladle shroud are mainly classified into aluminum carbon, aluminum-zirconia carbon and alumina-magnesia carbon. This kind of refractory nozzle is provided with good liquid steel washing resistance performance and liquid steel erosion performance in the course of use, which can effectively prevent oxidation of air to liquid steel and its spatter.
Advantages and Application
Changxing Refractory ladle shroud enjoys performances of purifying liquid steel, prevent liquid steel oxidation, with good liquid steel washing resistance and erosion resistance.
