What is the effect of the ingredients of the intermediate frequency furnace lining material on the application?

The lining of the intermediate frequency furnace is made of refractory bricks. Because the working conditions of each part of the lining are different, the raw materials and functions of the refractory bricks selected are also different. For example, the upper and middle linings of the furnace body are mainly considered wear-resistant, and the lower part of the furnace body and the furnace waist are mainly considered to be resistant to resistance. For thermal shock damage and alkali metal corrosion, primary slag corrosion with high FeO is considered for the hearth, and for the hearth and the bottom of the furnace, the resistance to mechanical erosion of molten iron and the differential thermal expansion of refractory bricks are primarily considered.

The batching includes two aspects: charge weight and batching composition. Hongda, who has many years of experience in intermediate frequency furnace charge, takes the oxidation method as an example to illustrate that if the carbon content is too high, the amount of ore will be added or the oxygen time will be extended.

Ingredients: Prohibition of ingredients will easily lead to improper control of chemical components during the exercise process or lack of casting castings, and may also cause excessive addition and consumption. If the chemical components of the charge are prohibited, it will bring difficulties to the exercise operation, and in severe cases, the exercise will not be carried out. .Generally, the ingredients are made according to the steel grades, equipment conditions, existing raw materials and different training methods.

Hongda, who has many years of experience in intermediate frequency furnace charge, takes the oxidation method as an example to illustrate that if the amount of carbon is too high, the amount of ore will be added or the time of oxygen consumption will be extended; the amount of carbon If it is too low, it is bound to increase carbon after melting; if S and P in the charge are too high, it will bring great difficulties to the operation before the furnace, not only extending the training time, but also severely corroding the furnace lining, and sometimes even stopping the training. In order to prevent the above situation , It is important to master the chemical composition of steel materials and ferroalloys before ingredients.
