Assembly
technology for big blocks of full refractory fiber and light type steel construction are adopted in the new type
furnace. The furnace body has the advantages of light weight, good heat insulation, easy installation and long use life. The developed automatic adjustable high speed burners has the advantages of burning process under control, high outlet speed, sufficient burning, forced circulation of gas in furnace and new heat supply method about large energy concentrate heat supply, strengthening convection heat transfer and pulse type heat supply is made. The developed
technology of central exhaust, pressure automatic controlling in furnace, full seal of furnace body can control heat current in furnace effectively. New controlling method of heat current in furnace is made and the uniformity of temperature field in furnace is increased. The heat
treatment technical curve could be calculated, operated, displayed and stored by means of the computer automatic control system. So the whole procedure is under control and high precision heat treatment is achieved. Varies of new type furnace such as movable furnace body assembly type, local assemble taking apart type, loading on truck type are developed. Different type of furnace could be selected according to different technical request, different size of work-piece and different installation site. Great breakthrough has been made in heat treatment furnace technology in China. Obvious effect is achieved in aspect of increasing precision of heat treatment, energy conservation and environmental protection. The integrative technology of new type furnace has caught up with and even exceeded the foreign advanced level. But the status of heat treatment furnace applications nowadays is rather behindhand. Application of new technology should be greatly pushed.
