Bubble Alumina
Product Number:
As is known, bubble alumina is a high-temperature resistant refractory material. The bubble alumina SHUO CHENG offers possesses extremely high mechanical strength (several times higher than that of general light goods), well suitable for blast furnace with an up to 1800℃ temperature.
Besides, the bubble alumina can be used as high temperature and extremely high temperature insulation materials, high-heat-resistant lightweight aggregate refractory concretes, high temperature castables, etc. In addition, the lightweight refractory material is extensively applied in high temperature and extremely high temperature kilns like gasifier for petrochemical industry, reaction furnace for carbon black industry, induction furnace for metallurgical industry and so on, achieving very satisfactory energy-saving performance.
