What are basic refractories?
Basic refractories are materials that have a high resistance to alkaline materials and are commonly used in applications where they will come into contact with basic substances such as lime, concrete, and cement. They typically consist of magnesia, dolomite, or chrome oxide as the main component, providing excellent resistance to high temperatures and chemical attack from basic compounds. Basic refractories are used in industries such as steelmaking, cement production, and glass manufacturing.
What is use of refractories?
Refractories are heat-resistant materials used in various industries to line furnaces, kilns, and other high-temperature processing equipment. They provide insulation and protection against extreme heat, chemical corrosion, and mechanical stress, allowing these industrial processes to operate efficiently and safely at high temperatures.
Why you used carbon refractory at blast furnace?
Carbon refractories are used in blast furnaces because of their high resistance to heat and thermal shock. They can withstand the extreme temperatures and chemical reactions that occur during the iron-making process. Additionally, carbon refractories have good thermal conductivity, allowing them to efficiently transfer heat in the furnace.

When was Harbison-Walker Refractories Company created?
Harbison-Walker Refractories Company was created in 1905.
What are refractory mineral?
Refractory refers to inorganic non-metallic materials that above 1580 ℃ refractoriness. Refractory variety, usually divided according to the level of ordinary refractoriness refractory (1580 ~ 1770 ℃), advanced refractories (1770 ~ 2000 ℃) and grade refractory (2000 ℃ above); divided by the chemical properties of acidic refractories, neutral and basic refractories refractories. In addition, there are special occasions for refractories.
Do steel investment foundries make use of clay refractories?
Steel investment foundries make use of clay refractories

What are refractories?
Refractories are generally ceramic materials that are capable of withstanding high temperatures. The bulk of refractory materials consist of single or mixed high melting point oxides of elements such as silicon, aluminum, magnesium, calcium and zirconium.
What is refractory?
Acid refractories are refractories that are composed principally of silica and reacts at high temperatures.
