Natural Gas High Working Temperature Heat Treatment furnace Car Bottom Furnace

1. Working mechanism

The trolley furnace is a batch type operation furnace. The structure of the car bottom furnace: the furnace bottom is a movable trolley.

Before heating, the trolley is charged outside the furnace, and the work parts are placed on a support iron, and then the trolley is pulled into the furnace by the traction mechanism for heating. After heating, the trolley is pulled out of the furnace by the traction mechanism for unloading. Or use a crane to lift the heated workpiece to the forging equipment for processing.

2.Technical Parameters

3.Structure Introduction
The shell of this series of electric furnace is welded with steel plate and section steel, and the bottom of the furnace body is connected with the trolley light rail. Users do not need basic installation, but only need to put it on the flat cement ground.

3.1 furnace body

The furnace body steel structure is made from 8# -12#U steel and steel plates.

3.2 furnace lining

The lining material is 1200℃ high aluminum refractory fibre compacted block. The thickness of the high temperature refractory layer is of 355mm.

3.3 bogie

The bogie is comprised of heat preservation material, bogie frame and moving mechanism. The refractory layer is divided into 3 sub-layers, i.e., 1st top high-alumina brick layer, and 2nd and 3rd layer with both light clay bricks.

3.4 sealing

The sealing between the bogie and the furnace body adopts a refractory fiber sealing block, which is pressed by an electric cylinder lever, and works in conjunction with the electric cylinder of the furnace door.

3.5 furnace door

The furnace door is comprised of all-fiber lining and steel structure shell. The door is built with silicate aluminum compressed fiber blocks same as that for the furnace body.

3.6 burning system

The burning system is comprised of Krom high speed burners, proportional combustion control system, gas valve, solenoid valve, burner control box, etc.

3.7 control system

The control cabinet is controlled by electric button, and anti overturning device is installed to ensure convenient use.

Note:The furnace for heat treatment system adopts energy saving fiber cotton as furnace lining, and the energy-saving effect is more obvious, up to about 30%.
