Development of Mathematical Model for Heat Transfer Analysis of Cylindrical Induction Furnace Wall

Mechanical Engineering

Furnace are most almost continuously used for melting of materials. Induction Cylindrical and spherical furnaces are more invaluable as no fuel is required. The purpose of the furnaces is to chemically reduce and physically convert iron oxides into liquid iron it is called as hot metal. Handling of furnace unit is not simple issue. It is a difficulty to search out life cycle of Induction type cylindrical furnace wall beneath load variant. The Induction type cylindrical furnace wall is made-up of silica ramming mass by experimental study which is one variety of refractory material. During the furnace operation various hazards like fire and explosion, furnace gases is more hazardous and explosive in a nature arise. The issue of induction type cylindrical furnace wall loses its properties after some cycles and hours. The problem comes from this Induction type cylindrical furnace is losing its life cycle and disturb production schedule in industries so we needed proper life span of the furnaces. The failure happens because of cyclic thermal stress due to heating and cooling cycle in furnaces. The problem of these furnaces will occur by computational heat transfer analysis by mathematically method. It is explicit finite difference analysis method. We also work on modification and the area of efficiency, cost, material used in furnace and analysis by mathematically solution. We made mathematical model on Turbo C^(++) software and analysis of cylindrical induction furnace. By which we have find life cycle of furnace wall with various types of refractory materials used making furnace wall. We found forecasting life span of cylindrical and furnace by used of finite difference method and divided in nodes. We are plotted output values on stress v/s life cycle graph.
