Coke is the key ingredient to reduce iron ore to pig iron within the blast furnace in integrated iron and steelmaking plants. The iron output performance of the blast furnace, which runs continuously over many years, is very much dependent on the quality of the coke used in the iron making process.

The coke oven is a key process used to make coke from powdered and blended coal and needs careful control of the furnace atmosphere to ensure that volatile components are removed correctly without complete combustion.

The working life of the refractories used in coke making can be reduced significantly by the repeated actions of thermal and mechanical shock damage and particulate errosion as well as having to operate at temperatures between 1,200-1,300°C. 

Fibretech's range of stainless steel and polypore fibres help to improve refractory life by significantly improving toughness or crack resistance and wear characteristic and are used in many areas of the coke oven – reducing maintenance down-time, improving operating efficiency and lowering refractory costs by improving refractory performance. They can also be used with refractory to make effective intermediate gunning repairs between re-lines.
