What are refractory materials examples?

The typical refractory materials include fireclay refractories, high alumina refractories, silica brick, Magnesite refractories, Chromite refractories, Zirconia refractories, Insulating materials and Monolithic refractory.

What are refractory raw materials?

Minerals commonly used for refractories include (but are not limited to) alumina, bauxite, graphite, kaolin, magnesia and zirconium. These minerals are produced globally but, in some cases, not always of grades suitable for refractory applications (e.g., alumina and bauxite).

Why is it important to understand the corrosion of refractories?

Refractories are subjected to chemical degradation at high temperature caused by their environment, which can be significant, if not catastrophic. Corrosion is a complex matter, which will remain a recurrent topic, always to be considered. So, understanding the corrosion of refractories is crucial to extend campaign lifetime.

What are the different types of alumina refractories?

Corundum based High Alumina Refractory Less than 5% SiO 2 Less than 3% Fe 2 O 3 and TiO 2 High corrosion resistance High thermal conductivity Electric arc furnace roof In petrochemical industry Price of high alumina refractory brick is $100-500 per ton. Magnesite is a group of carbonate mineral.

Which is the best type of refractory for glass?

Fused cast is the process in which the raw materials are heated up to 2000 ◦ C, cooled and casted. These refractory have 0% porosity. They have Strong glass corrosion resistance and high thermal shock stability. Good wear-resistance, drags-resistance and alkali corrosion resistance.

How is the manufacturing process for refractory brick?

Most of refractory brick has this similar manufacturing process except one or two. The raw material for the refractory brick is processed to remove the impurities. Then the processed raw materials are mixed is done in Muller or counter flow mixer for 10-20 minutes. Shaping is done by pressing or casting.
