Refractory Products

At Wedge India we offer wide range of Refractory products made of wide range of raw materials and products that are designed to withstand high temperatures and harsh conditions. These products are used in various industries for lining furnaces, kilns, reactors, and other high-temperature equipment. Here are some common types of Wedge Refractory Products:

1. Refractory bricks: Refractory bricks are solid, shaped blocks made from refractory materials such as fire clay, alumina, silica, magnesite, and chrome. They come in various shapes and sizes, including standard bricks, arch bricks, wedge bricks, and special shapes. Refractory bricks are used for lining the walls, floors, and roofs of high-temperature applications.

2. Refractory castables: Refractory castables are mixtures of refractory aggregates, binders, and additives that are typically mixed with water to form a slurry. They are then poured or gunned into place to create a monolithic lining. Refractory castables offer flexibility in installation and are used for various applications, including furnace linings, kiln linings, and repair work.

3. Refractory fibers: Refractory fibers are lightweight and flexible materials made from ceramic or mineral fibers. They are used for insulation purposes in high-temperature applications. Refractory fibers can be woven into mats, blankets, papers, or boards, and they provide excellent thermal insulation and energy conservation in furnace linings, kiln linings, and other heat-intensive equipment.

4. Refractory mortars: Refractory mortars, also known as refractory cements, are specialized cementitious materials designed for bonding and sealing refractory bricks and other refractory materials. They have high temperature resistance and are used for joining and repairing refractory linings.

5. Refractory coatings: Refractory coatings are thin layers of refractory material that are applied to the surface of refractory linings to enhance their performance. These coatings can improve resistance to erosion, thermal shock, and chemical attack. They are commonly used in industries such as steelmaking and petrochemical processing.

6. Refractory monolithics: Refractory monolithics refer to unshaped refractory materials that are installed in a plastic or semi-plastic state and then harden in place. They include materials such as ramming mixes, gunning mixes, and plastic refractories. Refractory monolithics offer easy installation and are used in areas where traditional brickwork is not feasible or cost-effective.

7. Refractory precast shapes: Refractory precast shapes are custom-designed refractory products manufactured in a controlled environment. They are prefabricated to specific shapes and sizes before being delivered to the site. Refractory precast shapes offer precision and efficiency in installation and are used in complex furnace linings, ladles, and other specialized applications.

Here are some common types of refractories you buy at Wedge India

1. Fireclay refractories: These are made from fire clay, which is a type of clay rich in alumina and silica. Fireclay refractories are versatile and widely used. They have good thermal shock resistance and are suitable for applications with temperatures up to 1,600°C (2,912°F). They are commonly used in fireplaces, chimneys, and low-temperature industrial applications.

2. High alumina refractories: These refractories are made from high-alumina content materials, typically containing 45% to 95% alumina (aluminum oxide). High alumina refractories have excellent resistance to high temperatures and abrasion. They can withstand temperatures up to 1,800°C (3,272°F) and are commonly used in steelmaking, glass manufacturing, and other applications involving high temperatures and harsh chemical environments.

3. Silica refractories: Silica refractories are made from silica (silicon dioxide) and have a high silica content. They have good resistance to acidic materials and are commonly used in the glass industry and certain chemical processes. Silica refractories can withstand temperatures up to 1,700°C (3,092°F).

4. Magnesite refractories: These refractories are made from magnesite (magnesium oxide) and have high resistance to basic materials. Magnesite refractories are used in applications such as steelmaking, cement production, and non-ferrous metal refining. They can withstand temperatures up to 2,000°C (3,632°F).

5. Chrome refractories: Chrome refractories are made from chromium oxide and have excellent resistance to corrosion and erosion. They are used in applications involving molten metals and in environments with high alkali content. Chrome refractories can withstand temperatures up to 1,700°C (3,092°F).

6. Carbon refractories: Carbon refractories are made from carbon or graphite and have excellent resistance to high temperatures and chemical attack. They are used in applications such as electric arc furnaces and ladles for steelmaking, as well as in the production of non-ferrous metals. Carbon refractories can withstand temperatures above 2,500°C (4,532°F).

7. Zirconia refractories: Zirconia refractories are made from zirconia (zirconium dioxide) and have high resistance to thermal shock and chemical corrosion. They are used in applications that require resistance to molten metals, glass, and slags. Zirconia refractories can withstand temperatures up to 2,700°C (4,892°F).
