product characteristics and uses

refractory clay is refers to the refractoriness is greater than 900 ℃, can do refractory clay and used as refractory bauxite. they besides have high refractoriness, under high temperature conditions can keep the stability of the volume, and has the ability of slag resistance and thermal shock resistance, and certain mechanical strength, and therefore very firm after calcination. is complete in kind and clay minerals, fenbumian wide, according to the nature and purpose can be divided into ceramic clay, refractory clay, clay brick and tile clay and cement. hard clay often show block or plate shape, generally not immersed in water dispersion, high refractoriness, as the main raw material of refractory products. refractory clay of hard clay is used for production of blast furnace refractories, ironmasters, hot blast stove, the ladle lining brick, brick. in the ceramic industry, hard clay and semi-rigid clay can be used as a manufacturing daily-use ceramics, building ceramics and industrial ceramics raw materials.
