Production process of aluminum carbon brick and its damage mechanism in steel industry

Aluminum carbon brick belongs to the range of aluminum carbon refractory materials. The so-called aluminum-carbon refractory refers to the carbon composite refractory formed by combining alumina raw materials and carbon raw materials, and in most cases, other raw materials such as silicon carbide and metal silicon, bonded with an organic binder such as asphalt or…

What Are Refractories?

Refractories are ceramic materials designed to withstand the very high temperatures (in excess of 1,000°F [538°C]) encountered in modern manufacturing. More heat-resistant than metals, they are used to line the hot surfaces found inside many industrial processes. In addition to being resistant to thermal stress and other physical phenomena induced by heat, refractories can withstand…

Factors affecting the high temperature mechanical properties of self-bonded SiC refractories

The thermal conductivity, oxidation resistance, and alkali corrosion resistance of self-bonded SiC refractories are superior to Si3N4 bonded SiC refractories. This article focuses on analyzing the high-temperature mechanical properties of self-bonded SiC refractories, as follows: 1. High-temperature mechanical properties of self-bonded SiC refractories without catalyst Figure 1 shows the high-temperature flexural strength of self-bonded SiC…

Exploration on Reuse of Waste Refractory Materials Used in Iron and Steel Industry

Application status of waste refractory materials in the steel industry Refractory material are widely used in the iron and steel industry. Metallurgical industry or building material production enterprises need to purchase a large number of refractory materials required for high-temperature operations to ensure continuous production. In the production process of iron and steel enterprises, a…

Why do most furnaces in the steel-making industry use magnesium-calcium refractories materials?

The main chemical composition of magnesium-calcium refractories The main chemical components of calcium-based refractory materials are MgO and CaO, and the main phases are periclase and Calcite, which brings together the advantages of MgO and Ca0. Table 1 shows the thermodynamic properties of several common oxide refractory materials. Compared with magnesium-chromium refractory materials, the magnesium-calcium…

How to test the refractoriness of commonly used refractory materials? With refractoriness value

What is refractoriness? Refractoriness refers to the property of resisting high temperature without melting under no load and reflecting the high-temperature characteristics of raw materials. The meaning of refractoriness is different from the melting point. The general refractory raw materials are composed of multiple mineral phases and are not single pure substances, so there is…
