Essay

The thesis is devoted to choice of modes, saving energy, of heat of metal in chamber heating furnaces equipped with regenerative torches. The chamber furnace equipped with regenerative torches with ball regenerators is built a tested. Mathematical models of the heating chamber furnace with regenerative torches and ball regenerator based on the circuit of a stratum of heat exchange are developed and realized as the programs on personal computers, their adaptation is made. The settlement way also experimentally establishes main parameters of use of fuel and economies of fuel from application of regenerative torches. The parameters of burning of fuel in furnaces equipped with regenerative torches are determined for want of which the satisfactory uniform of heating of ingots of a large mass on length of the furnace is reached. The best value of specific thermal potencies of chamber furnaces with traditional brick regenerators and with regenerative torches is determined from the point of view of the savings of energy. The circuit of the supersize heating furnace with deep thermal and chemical salvaging of ejections is developed which differs by that all elements of the circuit are industrially tested and can be designed with the help of authentic techniques. The ecological expediency of development of the given direction of construction of furnaces is shown. The new approximate solution of heating of skew fields of the correct form in a reverse flow with gases is obtained which differs from known before approximate solutions by simplicity of application and higher order of exactitude.
