types of refractory materials

Adding lime will increase the green strength of silica refractory. They are formed from a metamorphic rock. Non-fired refractory products are refractory materials that are made of granular, powdered refractory materials and suitable binders but are directly used without being fired. Clay bricks are a widely used refractory material. Fired refractory products are refractory materials obtained by kneading, molding, drying and high-temperature firing of granular and powdery refractory raw materials and binders. For example, basic refractories are best used when the refractory environment is also basic or … Refractories are inorganic, nonmetallic, porous, and heterogeneous. Siliminate based High Alumina Refractory: If Siliminate is used, the resultant product will have, If Mullite is more, then the resultant product will have, If bauxite is used, the resultant product will have, If corundum is used, the resultant product will have. They are acidic refractories, they resist acidic slag attack but attacked by basic slags. Brick is a practical lining material for refining furnaces, electric furnaces, glass melting furnaces and cement rotary kilns. Fused cast is the process in which the raw materials are heated up to 2000◦ C, cooled and casted. Finishing: They have good thermal shock and good corrosion resistance. The price of one aluminum based monolithic refractory brick is $ 20-90 per brick. Silica brick is a refractory material containing at least 93% SiO2. They have good thermal spalling resistance. It is an essential basic material to ensure the production and operation of the above-mentioned industries and the development of technology. They also act as mineralizer (Enhance the phase transformation of silica). Actually, there are some other classification standards of refractory. Types of Refractory Metals and Their Applications. Magnesium bricks are mainly used in open-hearth furnaces, electric furnaces, and mixed iron furnaces. Oven Drying is done for 150-250◦ C for 20 to 30 hrs. Good wear-resistance, drags-resistance and alkali corrosion resistance. 4 Uses of Copper Tungsten Alloy You Mightn't Know. Price: The fired refractory bricks are visually inspected for presence of cracks or any defects. Zirconia bricks are the bricks which have more than more than 65% of ZrO2. Magnesia brick is one type of common refractory material. What Can Molybdenum Compounds be used for? Silica refractory products consist of 93% silica. We provide customers with high-quality refractory metals at a very competitive price. The price of magnesia chrome refractory is $ 400-1300 per ton. The price of one refractory brick is $400-1300 per ton. The casting material is mostly used in various industrial furnaces. Monolithic refractories are the unshaped refractories. They are the most widely used … High alumina refractory contains more than 45% Al2O3. The raw material is quality rocks. Refractory materials generally refer to the inorganic nonmetal materials with a refractory degree of 15800C or above. Manufacturing Process: Chemical classification of a refractory material refers to whether it is a basic, acidic or neutral material. Metal with High Melting Point | Top 10 Metals with High Melting Points, 6 Uses of Molybdenum | Facts About the Applications of Molybdenum, Features & Applications of Tungsten Crucibles, Properties & Applications of Molybdenum Copper Alloy, Factors Affecting the Performance of Tungsten Powder. The inspected refractory bricks are then tested to check if it is having some specific property to use that brick in some fields. They resist alkali slag attacks.

They are used in mining, metallurgical industries. They have high corrosion and erosion resistance, good thermal shock resistance and high volume stability and used for normal carbon and high carbon steel production. The price of zircon refractory is $ 25000-65000 per ton. The price of magnesia based carbon refractory brick is $ 900-1300 per ton. The price of the low iron insulating brick is $80-720 per ton. Firing: They are often used in masonry blast furnaces, hot blast stoves, glass kilns, rotary kilns, etc. Insulating bricks are lightweight bricks with low thermal conductivity. They have high refractoriness, Thermal stability at high temperature and slag resistance. Types of Refractories: Refractories are used in all kinds of industries with the furnace to reduce the heat loss. There are refractory metals that have ultra-useful capabilities such as acting as outstanding radiation shields as well as chemical catalysts.
