用途: 高速钢、锻模钢、不锈钢的淬火回火，不锈钢、耐热合金钢、Be-Cu溶体化及时效处理、退火，磁性处理，铜氧焊，烧结等。
Applications: high-speed steel, die steel , the quenching and tempering of stainless steel, stainless steel, heat-resistent alloy steel,  the solution and aging treatment of Be-Cu, annealing , magnetic processing, brazing ,sintering.
对流加热系统之优点:
在低温区域(T < 850˚C) 急速升温及持温，缩短热处理制程时间。
大型模具或大量处理时，可确保加热均匀。
缩小工件内外温差，应力消除容易，有利于降低变形量。
可用于退火或光辉回火处理。
The Advantages of Convection Heating System:
Rapid heating and holding are carried out in the low-temperature zone (T < 850˚C) and the duration of heat treating processes are reduced. 
Uniform heating can be ensured during the heat treating of the large-size die-casting dies or workpieces in bulk processing.
Reduce the temperature difference between the inside and the outside of the workpiece. With the ease of stress-relieving, the deformation can be easily reduced.
Annealing and bright tempering can be carried out.
