1800 degree high alumina sk34 refractory clay brick muffle furnace fireclay bricks sk34 for fireplace
Products Description
1800 degree high alumina sk34 refractory clay brick muffle furnace fireclay bricks sk34 for fireplace
is a kind of insulation material adopting organic matter as ignition loss substance in order to increase the porosity of refractory, which has such advantages as high porosity, small volume density, good insulation effect, high mechanical intensity, small thermal conductivity and long service life. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.
Feature
1.Low coefficient of linear expansion
2.Low thermal conductivity,
3.Strong resistance to the acid slag erosion,
4.Excellent thermal shock resistance,
5.High Refractoriness under load,
6.Low high-temperature creep rate.
