Good Plasticity High Temp Fe2O3 Refractory Brick Mortar
Definition:
Refractory cement mortar base stock is hard chamotte, combined with soft fire clay or chemical bond, mainly used in blast furnace, hot-blast furnace, coking furnace, soaking pit furnace, heat exchange, boiler and furnace seam and repair constructed by fire clay bricks.
Refractory cement mortar is of high fire resistance, strong glass erosion resistance, good operational performance, strong bonding property, good water retaining property & workability and without sediment by making into slurry. Its combination with ceramic under high temperature improves all properties further. High packing density and less water consumption make compact structure of brickwork.
Refractory cement mortar is normally divided into four types according to physical and chemical indexes. It is mainly the auxiliary product for fire clay brick construction, with the refractoriness of 1580~1750℃, water content of ≤6%. The Fe2O3 content in refractory mortar for blast furnace construction shouldn’t be over 2.5%.
Advantage:
(1) Good plasticity and convenient construction;
(2) Great bonding strength and strong corrosion resistance;
(3) High refractoriness, up to 1650℃±50℃;
(4) Good resistance to slag intrusion;
(5) Good to spalling
Application:
1. coke ovens
2. glass furnaces
3. blast furnace hot blast stove
4. metallurgy
3. building materials
3. machinery
4. petrochemicals
5. glass
6. boilers
7. electricity
8. steel,
9. cement, etc.
