| Coke oven is a large chambered refractory structure in which the coke, one of the indispensable raw materials for iron making, is produced.
Generally the lower portion of the furnace is regenerator and the upper one is partitioned vertically into many coking chambers and combustion chambers, which are arranged alternatively.
Coal charged into the coking chamber is heated by two hot side walls partitioning the adjacent combustion chamber of 1100 ? 1350 deg C then is carbonised at approximate 1000 deg C.
Silica bricks, which show sufficiently high refractoriness under load and reliable volumetric stability, are highly recommended to construct both chambers.
The generic requirements of coke oven refractory bricks are:- Excellent mechanical strength at high temperature, e.g. hot modulus of rupture
- Excellent volumetric stability?
The life cycles of coke oven being long (30-40 years), it is very important that the materials used conform to excellent quality, high precision dimensional accuracy and tolerance. SGRL supplies high quality and reliable silica bricks too meet all the requirements from it?s customers. |
