Detailed Description

Taking a tunnel type mould shell roasting furnace of 15 m as an example, the kiln is 1 m wide and the pitch is 2 m, and the production process comprises the steps of furnace feeding, heating, loading, transferring and the like. The chain type stepping mechanism of the kiln car in the transferring stage of the casting area is shown in fig. 1, and comprises parts such as a chain type stepping machine 3, a stepping machine bracket 5, the kiln car 6, a casting area track 13 and the like. The stepper brackets 5 are arranged on two sides of the casting area track 13, the chain stepper 3 is provided with a driving rod 2, and the driving rod is arranged on the stepper brackets 5.
