Refractory Corundum Mullite Ceramic Push Plate With High Working Temperature
Good thermal shock resistance Cordierite mullite refractory plates / brick / board / kiln shelves for sanitary ceramic kiln Plain Batts are the most common type of primary kiln furniture, usually produced by semidry pressing, but can also be made by pressure casting. Extruded batts can be split into three categories as follows.
Lots of sizes and shapes with the thickness of 25mm,30mm,38mm,45mm,70mm and width under 700mm,length under 1650mm.
Extra Large Batt, Extra Thin Batt, Plain Batt, Perforated Batt, Grooved Batt,Trapezoid Batt, Recessed Batt, Full Disc, Half Disc and Special Batt are also workable according to the design of the customers.
Product Description
1.Low bulk density, low thermal conductivity, good thermal insulation performance.
2.Corundum-Mullite Refractory Bricks allow direct contact of fire, suitable ofr various atmosphere.
3.Good integrity with furnace lining, long service life, easy operation, could be shaped freely.
Product specification: standard form, normal standard, shaped and special shaped bricks.
Corundum-Mullite Refractory Bricks Can be used in various kilns because of its cheapness and general tray package. Among all of the refractory materials, it is the most widely used.

Features:
(1) strong resistance to erosion and scouring of molten iron and slag;
(2) good thermal shock resistance and re-burning volume
(3) strong anti-oxidation ability;
(4) easy to construct, can be quickly baked without bursting, easy to repair and dismantle;
(5) when used, no harmful gas, no sticky iron, long life. These features make them complementary and should be compatible with each other.
