Melt Surface Insulation Powder - Isotherm Powder - Radex

Isotherm Powder In steel mills, ladles and tandis are used to transport the melt from a specific location furnace. Depending on the conditions, the type of body design and refractory spatulas and tandis as well as ambient temperature drop conditions are different. Boil lid due to the use of alumina masses and spending time to repair and install refractory materials has a higher cost than the use of isotherm powder. It is added on the surface of the melt. The main task of this powder is to insulate the surface of the melt to prevent the temperature drop and the melt is oxidized by the atmosphere. The isotherm powder used with a suitable chemical composition must have good thermal conductivity and viscosity to have a good performance. Insulation of the melt surface reduces melting costs by reducing the furnace melt discharge temperature and less corrosion of furnace refractories, ladles and ovens, and increases the absorption of molten non-metallic impurities. Isotherm consumption depends on the tonnage of the steel, the design of the pot and the tensile and the casting time. Isothermal powder becomes integrated when it is placed and spread on the molten surface of steel and begins to insulate the molten surface. When casting time is increased for any reason, this powder plays an important role in controlling the temperature drop. Isolation Melt the surface in the traditional way is done by raw and fried rice bran, which is associated with contamination and respiratory problems for employees. Raw rice bran, when placed on the surface of the melt, first takes the temperature of the melt to burn itself and creates a lot of smoke, and after burning, begins to isolate the molten surface. Due to the problem of water shortage and drought in the country and Also, the problems facing agriculture are facing the supply of rice bran. Rice bran is not always readily available and was scarce in some seasons. Due to its low weight and high volume, rice bran needs more transportation and therefore higher transportation costs. It also needs more storage space than the isotherm because it is bulky.

In continuous casting after transferring the pots from the melting section to the continuous casting unit, simultaneously with the discharge Intramuscular melting In casting, to prevent a drop in the temperature of the melt inside the patellar tendon, it is necessary to add a suitable coating to the melting surface to prevent heat loss of the melting due to radiation, conductivity, convection. This task is performed by a layer of solid and sintered powder. In addition, it protects the melt against surface oxidation and absorbs some of the impurities in the melt. This powder reduces the temperature drop of the melt in the pan and the tandish, and this causes better control of the casting speed, reduces the amount of oxygen in the melt and in general improves the casting conditions with better control. It is clear that preventing the drop in melt temperature has a significant effect on economic production, reducing energy consumption, increasing the refractory life of the pan and tandem. This material also prevents re-oxidation of steel by the atmosphere and due to the high ratio of calcium oxide to silica in this powder, it reduces the oxygen in the melt and also prevents the nozzle from being blocked by alumina impurities and desulfurization is better.

The consumption of this powder is approximately 0.5 to 1 kg per ton and it must be poured on the surface of the melt and stored in a completely dry environment without moisture.
