RUT340 Coke Oven Door Castings
Coke oven doors are made of
vermicular graphite cast iron RUT340, placed at the ends of a coke-oven coking chamber. These doors are often times provided with a sealing strip to assure the coking chamber is sealed shut so that by-products of the coking process, such as carbon gases, do not escape the coking chamber and pollute the atmosphere.
Vermicular graphite irons have certain advantages over the older members of the cast iron family viz. gray, ductile and malleable irons:
-
The tolerable content of sulfur in VG iron is much higher than in ductile iron;
-
The temperature range in which the reaction material is effective is very wide in VG iron as compared to SG iron.
