What is the best refractory material?

Hafnium carbide is the most refractory binary compound known, with a melting point of 3890 °C. The ternary compound tantalum hafnium carbide has one of the highest melting points of all known compounds (4215 °C).

What is refractory manufacturing?

Refractory manufacturing involves four processes: raw material processing, forming, firing, and final processing. Firing involves heating the refractory material to high temperatures in a periodic (batch) or continuous tunnel kiln to form the ceramic bond that gives the product its refractory properties.

What is refractory business?

The Indian refractory industry is a Rs 9,000 crore market, with major players such as TRL Krosaki, Dalmia OCL, RHI Magnesita India. About 75\% of the refractories manufactured using magnesia, alumina or silica is used with the rest being consumed by cement and glass, ceramics, petrochemicals and boiler industries.

What is refractory made of?

Refractories are produced from natural and synthetic materials, usually nonmetallic, or combinations of compounds and minerals such as alumina, fireclays, bauxite, chromite, dolomite, magnesite, silicon carbide, and zirconia.

Which refractory has high conductivity?

Of the refractory materials normally used in tonnage quantities, silicon carbide exhibits the highest thermal conductivity.

What are the requirements of good refractory?

A good refractory should have high RUL value. It is defined as the ratio of its pore volume to the bulk volume. Porosity is an important property of refractory bricks, because it affect many other characteristics like chemical stability, strength, abrasion- resistance and thermal conductivity.

What does a refractory contractor do?

The Contractor is responsible for the correct installation of the installed refractory. Installing Contractor (or manufacturer) is responsible for providing a proper material dry-out procedure for the refractory material installed.

How many types of refractories are?

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

What is the difference of Rul and creep?

Refractoriness under load (RUL) is a measure of the deformation behavior of refractory ceramic products subjected to a constant load and increasing temperature. The creep in compression test is also carried out in the machine to a maximum temperature of 1700°C.

What is neutral refractory?

i. A refractory that is neither strongly basic nor strongly acid, such as chrome, mullite, or carbon.

What is refractoriness casting?
