Detailed Description

Application 1200 three zones tube furnace is mainly used for preparation of rare earth, electronic lighting, crystal annealing, biological ceramics, electronic ceramics, special alloy, magnetic materials, precision casting, vacuum sintering of metal heat treatment and other industries, protective atmosphere sintering, vacuum coating, CVD experimental measurement, material composition, etc. Feature 1.Good quality high temperature three zones tube furnace ,heating element embedded in the chamber wall.When heating,tube furnace can ensure uniform temperature in the furnace. 2.Three zones tube furnace uses advanced lightweight aluminum oxide material molding.Compared with traditional tube furnace,the weight is reduced 40%.Heating preservation effect is good,heating faster,save energy. 3.Used double deck ventilation cooling structure,tube furnace works in high temperature,and the furnace shell sueface keep low temperature to advoid scald the operating personnel,safety is greatly increased.
