Sintering and reduction furnace are tailored to PM industry for the reduction of Fe, Cu, Co, Mo and W metal powders from respective oxides, also for the calcination and final reduction of Cobalt oxilate, APT and other metal salines.

       The equipment has a large output and a relatively simple structure and it is easy to adjust process parameters and control product quality, so it has been used as upgrading equipment replacing the old generation of furnaces, such as two-tube, four-tube and multi-tube reduction furnaces. It consists of feeding, reduction, slow cooling, cooling and unloading zones.
       Feeding zone includes feeding platform and entrance to muffle. On feeding platform there is a small feeding cart shuffling right and left to ensure well distributed feeding on the steel strip.
       The muffle in reduction zone is made of SUS310S high temperature resistant stainless steel. The muffle shell is corrugated to increase its strength and is placed on a SiC plate, on which the muffle slides as it expands when heated.
       Entrance at the feeding zone is sealed hermetically by a roller or by a gas curtain+ fiber curtain, leading to small gas consumption and nice seal.
       Material convey system consists of steel belt, transmitting device and multi-grade tension device. The belt speed is adjustable through the stepless frequency regulator.
      Temperature close-loop control system includes thermocouples, intellectual digital PID adjustor and SCR to ensure precise control of temperatures.

  Main specification and accessories:

    Note: Production capacity is calculated with following parameters:

             1. Iron power apparent density: 2.3~2.6g/cm3, generally calculate at 2.5g/cm3;

             2. Iron powder reduction time: 65~75min, generally calculate at 65min;

             3. Iron powder thickness on the belt: 30~35mm, generally calculate at 33mm;

             4. Iron powder width on the belt: belt width(mm) reduce 100mm

             5. Equipment utility:90%
