Mullite types of refractory bricks

Mullite types of refractory bricks
Product Detailed
Refractory brick density: 0.6-1.25g/cm3 temperature: 1260/1430/1540/1650/1760 degree Al2O3: 37-77% size: 230x114x65/75m

ZIBO JUNXU TECHNOLOGY CO,LTD  is the professional manufacturer and exporter of refracotry and insulation material . Our products mainly include insulating brick, refractory brick, refractory castable, ceramic fiber products. For insulating brick, the production capacity is 300tons per month, primarily export to SPAIN, USA, ITALY, TURKEY,AFRICA etc.

JM insulating brick, using high pure mullite as raw material, is made by adding alumina powder according to different type and then sintering in high temperature. JM insulating brick is the new energy saving material for insulation.

CHARACTERISTIC:Low densityHigh purityLow thermal conductivityExcellent thermal shock resistance

APPLICATION:glass industries iron & steel industriesceramics industries non-ferrous metals industrieselectrolytic Aluminum industries power generation industriesHeat surface fireproof lining other fire-proof back lining
