What is acid refractories?
Acid refractories are a type of ceramic material that can withstand high temperatures and harsh chemical environments with a high resistance to acidic corrosion. They are commonly used in industries like steel production, petrochemicals, and glass manufacturing where acidic conditions are prevalent. Acid refractories are typically made from silica and alumina as main components.
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.
What compound consists of aluminium and oxygen?
Aluminum oxide (Al2O3) is a compound consisting of aluminum and oxygen. It is commonly known as alumina and occurs naturally as the mineral corundum, which is a very hard crystal used in abrasives and refractories.
Is k3po4 acidic or basic?
No. K3PO4, potassium phosphate is a salt and it is basic.
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.
What is main purpose of refractories of boiler furnace?
one of the main purpose of refractories in the boiler furnace is to
When was Harbison-Walker Refractories Company created?
Harbison-Walker Refractories Company was created in 1905.
How do you determine the max temperature of high alumina refractories?
If the furnace is lined with refractories and the charge is full a 60% alumina will be 1600C.
Do 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.
