A mass of iron alloy powder mixed with an exothermic agent (an oxidizer mixed with iron-silicon powder or aluminum particles) . It will give off heat when it is added to the molten steel, so as not to reduce the temperature of the molten steel. The main varieties of ferro-alloys are ferro-chromium, ferro-silicon, ferro-manganese, ferro-tungsten, ferro-molybdenum and ferro-niobium. The shapes of heating ferroalloy are cylindrical, spherical, square, brick and so on. Each piece weighs from a few hundred grams to a few kilograms. Its melting point is close to that of Matrix ferroalloy, and its calorific value is generally 800 ~ 1000 KJ / kg.

The ferro-alloy is ground fine and mixed with heating agent, which is called heating ferro-alloy. It can be used in the form of press block, ball shot and so on, and has great exothermic effect when it interacts with liquid steel. The basic condition for the successful use of ferro-alloys in alloy steel production is that they can be burnt to obtain slag with good fluidity. If the resulting slag is liquid enough, the metal can melt rapidly even when the ignition point of the briquette is lower than the melting point of the ferroalloy.

These principles today more than ever form the basis of our success as an internationally active mid-size company for Refractory Metallurgical Fused Calcium-Aluminate Refining Slag for Refining Steel with Al2O3 52%Min. We are adhering to the business tenet of 'professional technology, honest management, and fair trade'. In the long-term operation, we have won the trust and support of many enterprises and established a good reputation in the industry. Ours team will do best for you always.
