Iron & steel industry consumes close to %75 of the refractories manufactured around the globe. The consumption speed of refractories in the iron& steel industry is very high. In regards to global consumption figures of refractories, total refractory material consumption of the sector is calculated to be 10kg per ton of liquid steel manufactured. This figure may shift depending on each country. It is possible to measure the performance life of refractories both in years (ex: ladle bricks) and in days (ex: blast furnace bricks) depending on the unit processors they are used at. Refractory products with very diverse characteristics and structures are being used during the steel production process taking place in integrated and mini mill plants alike. These products may be refractory bricks of various shapes and dimensions as well as castables with alumina silicate or basic material based.
Dolomite is a cost effective alternative to magnesia carbon refractories and yield to higher number of heats, especially for the si-killed steel production. The lower carbon content of doloma products enable cleaner steel production. Their lower thermal conductivity also make dolomite a better option in preventing the heat loss of ladles. Shipped in sets, dolomite bricks require lower storage costs for leftover bricks.
