Floating particle brick Heat-insulating Refractory Materials Iron and steel smelting
Refractory fired from refractory clay or other refractory materials. Light yellow or brown. It is mainly used in building smelting furnace and can withstand high temperature of 1580 ℃ - 1770 ℃. Also known as refractory brick. Refractory of certain shape and size. According to the preparation process, it can be divided into sintered brick, non sintered brick, fused cast brick (fused cast brick) and refractory and heat insulation brick; According to the shape and size, it can be divided into standard brick, ordinary brick, special-shaped brick, etc. It can be used as structural materials for high-temperature building materials, building kilns and various thermal equipment. It can withstand various physicochemical changes and mechanical effects at high temperature. Such as refractory clay brick, high alumina brick, silica brick, magnesia brick, etc.
Drift bead brick characteristic is mechanical strength is high, thermal conductivity is inferior, working temperature is inferior also, do not exceed the test temperature of change of reburning line. Therefore, this kind of product is used in metallurgy, machinery, chemical industry, petroleum, building materials, light industry, power and other departments of industrial kiln protection, generally can save 15%-40% energy, especially for intermittent operation of the furnace energy saving effect is the most significant. The mechanical strength is high, the thermal conductivity is low, the working temperature is low, does not exceed the refiring line change test temperature.
Floating particle brick
Floating particle brick, with drift bead as the main raw material made of heat insulation refractory products. Drift bead is aluminum silicate glass hollow bead which is flotation from fly ash of thermal power plant. It is light, thin wall, hollow, smooth surface, high temperature resistance, good heat insulation performance. By using these excellent characteristics of drift bead, light heat insulation refractories with excellent heat insulation performance can be made. Production of drift bead brick can be semi - dry forming.
