Refractory in metallurgy industries The metallurgical industry relies on the refractory industry for building materials. The ceramic industry also takes the metallurgical industry as the main refractory material market. In this country, they consume more than half of the total output. According to a study conducted at 1W$, open hearth furnaces absorb more than one-third of refractory bricks, blast furnaces and heating furnaces each account for about 7%, cupolas and smelting f

Types of Refractory Materials and Their Applications Silica : Pure silica melts at a very high temperature, namely 1713°C, but when it comes in contact with alkaline substances, it forms silicates, some of which melt easily. Therefore, the presence of alkali in silica used as a refractory material should be avoided. Silica occurs in the form of quartzite, Dinas rock and ganister. Ganister is a rock with a high content of natural silicon (98% SiO2). In the ready state, it is u

Insulation and Refractories Thermal insulators are poor conductors of heat and have low thermal conductivity. Insulation materials are used in buildings and manufacturing processes to prevent heat gain or loss. Although its main purpose is economy, it also provides more precise process temperature control and personnel protection. Prevent condensation on cold surfaces and the resulting corrosion. These materials are porous and contain a large number of inactive air pockets. T
