Chrome Corundum Castable Refractory
Chrome corundum castable refractory is a kind of quality monolithic refractory with chrome corundum as the main material. It is manufactured with a combination of high-quality refractory aggregate, fine powder, binders and additives, and after advancement in production technology, a single use for many purposes can be realized.
The mechanical property of the chrome corundum monolithic cast refractory is greatly improved, and it has excellent thermal shock resistance. It is widely used in electric furnace lining and other thermal equipment lining. It is also used in various non-ferrous metal smelting furnaces, chemical industry furnaces, metallurgical furnaces and other high-temperature furnaces.
The production process of chrome corundum cast refractory is to uniformly mix and knead the refractory aggregate, steel slag, corundum, boron nitride, graphite, additive and binder according to a certain proportion, and then vibration to make the slurry uniform and compact, and then after energy-saving drying. And sintering, finally solidify into a monolithic refractory material.
Chrome corundum castable refractory has high temperature strength, good thermal shock resistance and excellent wear resistance, so it can be used as a refractory material with excellent properties. Chrome corundum castable refractory is easy to construct, good in air tightness and insulation, good corrosion resistance and high strength after hardening and sintering, and it is suitable for the construction and maintenance of electric furnace and other thermal equipment.
In addition to the high temperature strength and good thermal shock resistance, chrome corundum cast refractory also has certain shock absorption and abrasion resistance, therefore, it can avoid the damage caused to the lining in the periodic operation of the furnace. In the use of chrome corundum monolithic refractories, attention should be paid to the heat-resistant grade and the use temperature, so as not to cause any damage to the refractory material in the use process.
In view of these advantages, chrome corundum cast refractory is also used in high temperature kiln linings, such as in a variety of ceramic kiln linings, furnace linings, and non-ferrous metal smelting furnace lining, metallurgical furnace lining, chemical industry furnace lining, and so on.
In the construction of chrome corundum cashable refractory, if improper construction operation is adopted, it will cause a series of problems, such as uneven abrasion, inability to meet the requirements of endurance and other issues, resulting in uneven insulation effect and shortening the service life of refractory. Therefore, before the construction, careful planning and careful construction are necessary to ensure the service life of refractories and the reliable, economical and efficient production of users. Generally speaking, strictly following the specifications and the requirements of the construction drawings is enough to ensure the effective and reliable service life of refractories.
