The utility model content
To the above-mentioned defective that prior art exists, the utility model aims to provide a kind of sintering furnace that is specially adapted to refractory metals such as tantalum class that can realize quick cooling.
To achieve these goals, the utility model adopts following technical scheme: sintering furnace comprises furnace shell, stove inner support, heat-insulation layer, refrigerating gas access equipment and cooling system, and said stove inner support and heat-insulation layer are provided with passage; Said cooling system can be communicated with the formation closed-loop path with the furnace chamber that said furnace shell forms.
As the improvement to the present technique scheme, said cooling system comprises the cooling circuit that is connected with cold-producing medium.
Compare with prior art; The utility model is owing to adopted technique scheme; Cooling effect to sintering furnace is outstanding, has shortened sintering cool time and whole sintering period greatly, has overcome the restriction of sintering period length to the production capacity performance; Improve the utilization rate and the production efficiency of sintering furnace, thereby increased the output and the benefit of product greatly.
