Sunrise Refractory High Quality Thermal Insulation Refractory Material for Sales

Date:2019-10-18 11:23 | From:Zhengzhou Sunrise Refractory | Author:admin
As a kind of high-efficiency thermal insulation refractory material, refractory fiber has the characteristics of soft fiber and high strength of general fiber, and can be processed into various products, such as felt, wire rope, belt, carpet, etc., and has the performance that ordinary fiber does not have. Such as partial oxidation resistance, corrosion resistance, high temperature resistance, etc., to make up for the shortcomings of the general refractory material is too brittle.
The refractory fiber has a small bulk density, usually 0.1 to 0.2 g/cm3, which is 1/20 to 1/10 of that of ordinary clay bricks and 1/10 to 1/5 of light clay bricks. Therefore, the use of refractory fiber instead of refractory bricks can reduce the weight of the furnace and reduce the thickness of the furnace wall. In addition, the refractory fiber is lower than the heat, which is only 1/72 of the ordinary refractory brick and 1/42 of the lightweight clay brick. Therefore, it is often used as a batch kiln lining, which can significantly reduce heat storage loss, save fuel and increase heating rate.
Refractory fiber products are increasingly used in industrial kilns and have achieved significant energy savings. For continuous operation of the furnace, the use of refractory fiber products can save 3% to 10%. For intermittent operation of thermal equipment, the use of fiber refractory energy-saving is more obvious, energy saving can reach 10% to 30%, or even higher. The masonry method of refractory fiber products has a great influence on its thermal insulation effect. When the lining is used, the direction of the fiber is perpendicular to the direction of heat flow, and the radiant heat is increased. Under the same conditions, the thermal conductivity of the lining is increased by 20%~30%; when used as a lining, the fiber direction and heat flow The direction is consistent and the thermal conductivity is mainly determined by the thermal conductivity of the product.
