(1) The bottom of the trolley furnace is a movable trolley. Before the workpiece is heated, the trolley is loaded outside the furnace; when the workpiece is heated, the trolley is moved into the furnace by the traction mechanism; after the workpiece is heated, the traction mechanism Pull the trolley out of the furnace for unloading. The operation is more convenient, and it is suitable for heating large workpieces and workpieces with complex shapes.

(2) The furnace temperature of the trolley furnace can complete a complete heating cycle in the furnace according to the process requirements. The heating process can be adjusted arbitrarily within a large range.

(3) The heated workpiece of the trolley furnace can be loaded within the effective range of the trolley, and is not limited by geometry, size, and weight.

(4) The temperature difference between the furnace temperature of the trolley furnace and the temperature of the heated X pieces is small.

(5) The trolley furnace is a periodic heating furnace, which is usually used for intermittent operation, so the heat storage loss is large. The large movable furnace door of the movable trolley is not easy to seal, the heat loss is large when the trolley is released, and the thermal efficiency of the trolley furnace is not high.
