              One, single supply a pair of two switched systems


               




              Advantage:


              Small investment


              Small floor area


              Two furnace body one with a prepared, there is a certain flexibility


              When a change of furnace lining, to ensure the continuity of production


              Disadvantages:


              At any time, the power supply cabinet can only be connected with a furnace body to work.


              The power supply cabinet is connected to the two furnace body by a pneumatic switch, and the furnace body is selected by an operating switch.


              If two furnace bodies are to be used at the same time, it is required to switch between the two furnace bodies frequently by the pneumatic switch.


              The pneumatic switch will be a failure point.



              Two system two, dual power drag


               


              Advantage:


              Two furnace body can work at the same time, a melting, a heat preservation.


              No external switch


              Small floor area.


              The total power can be arbitrarily distributed among two furnace bodies.


              Two furnace body can also be a use of a prepared, there is a certain flexibility.


              When a change of furnace lining, to ensure the continuity of production


              Disadvantages:


              Price is more expensive


              Three, single power supply three to two switch type system

               

              Advantage:


              Three dual use of the stove body, there is a certain flexibility


              At any time, when a furnace relining, ensure two furnace production at the same time small area


              Disadvantages:


              At any time, the power supply cabinet can only be connected with a furnace body to work.


              The two power supply cabinet is connected with the three furnace body by a pneumatic switch, and the selection of the furnace body needs to be realized through the operation switch.


              If three furnace bodies are to be used at the same time, it is required to switch between the three furnace bodies frequently by the pneumatic switch.


              The pneumatic switch will be a failure point.

              Four, single supply a pair of all change type system


               

              Advantage:


              Completely separate melting system, no influence on each other, working independently.


              With the increase of the demand, the number of the system can be increased without limitation, and the operation of the original system is not affected.


              Disadvantages:


              The power supply cabinet can not be switched between the furnace body and the furnace body.


              Expensive price
