Tap hole clay composition The quality of the raw materials of the taphole mud has a great impact on the quality of the taphole clay. Now large blast furnaces basically use high-purity raw materials to improve the quality of the taphole mud, which is generally composed of the following materials: Silicon carbide SiC has the characteristics of corrosion resistance, high temperature resistance, high ...

Taphole clay has been subjected to higher demands due to the development of blast-furnace smelting technologies. Taphole clay is no longer a consumable refractory but a functional one. It is not only responsible for sealing the taphole but also protecting the bottom side walls of furnaces and maintaining the stability of tapholes [1,2,3,4]. During operation, molten iron-slag constan...

ASC castables for iron troughs are generally low-cement or ultra low cement castables, which are mainly composed of Al2O3 aggregate, SiC, carbon, cement and various additives.     (1) Al2O3 aggregate Al2O3 aggregate is the main component of the castable and is the particle skeleton of the castable. Al2O3 aggregate mainly includes fused white corundum, brown corundum, sub-white corundum, ...

What is mullite?   Mullite is mainly composed of aluminum oxide and silicon oxide. It is a general term for aluminosilicate minerals. It is a mineral formed by aluminosilicate under high temperature conditions. Mullite is also formed when aluminosilicate is artificially heated. In recent years, my country has continuously increased the clean utilization of coal resources. The fly ash produced...

What affects the price of calcined bauxite?   Calcined bauxite is a bauxite material that has been heated at high temperatures. Bauxite, also known as bauxite, is a mineral rich in aluminum oxide, the main component of which is hydrated aluminum oxide, usually containing some impurities. In industrial applications, bauxite is a very important raw material.   The main factors affecting th...

Problems and solutions in the use of taphole clay   For steel mills, perfect waterless taphole clay should meet the following requirements: easy to make clay, easy to open, easy to maintain the iron taphole depth, the iron tapping time meets the requirements of blast furnace, no splashing and no smoke during the iron tapping process, etc.   In fact, it is impossible for any supplier...

Lightweight experiment of mullite refractory castable     With the implementation of the dual carbon strategy, the requirements of high-temperature industries for energy conservation and environmental protection are becoming more and more stringent, and the research and use of lightweight refractory materials are increasing. Mullite castables have excellent properties such as high load s...
