TB-C
For furnace bottoms of glass melting furnaces and parts of the tank block that
come into contact with glass, it is common to use AZS fused cast refractories
or alpha/beta alumina fused cast refractories. For furnaces with increased thermal
insulation, molten glass penetrates through joints in the fused cast refractories.
Furnace bottoms and lined bricks of tank blocks come into contact with glass that
flows in through the joints. Refractories used in these situations must have high
corrosion and pollution resistance against molten glass. Most suitable is tank
block that is carefully-selected clay-type materials, produced under appropriate
condition. Tank block is produced in a large mold to prevent further molten glass
penetration. |

RG-35
This fireclay brick uses special ingredients which is formed at high pressure
and fully sintered, so that it has very low porosity and is highly heat-resistant.
It is also highly alkali resistant and creep resistant. It is particularly suitable
for the lower parts of regenerator checkers, rider arch and middle and lower parts
of regenerators walls. |
|
RG-34
This product is fireclay brick that is dense and highly alkali-resistant. It is
suitable for lower parts of regenerator walls. |
|
 |
| Using carefully-selected quality ingredients, these stable quality
chamotte bricks are produced using a highly quality-controlled system. We offer
SK-34 and SK-32, depending on heat-resistance.
They are widely used in glass melting furnaces' melter, back-up material for working
end walls and walls/furnace bottoms of lower parts of regenerators. |
