Features：

- The bogie hearth tempering furnace is mainly used for tempering of high-chromium cast steel rolls, welding surface repair after rolling, eliminating welding stress tempering and tempering for other purposes, using microcomputer program process curve automatic temperature control cabinet, automatic high-precision execution of the best back Fire craft curve.

- The bogie hearth tempering furnace adopts composite furnace lining or full fiber insulation, and the furnace body and the trolley pass the self-sealing mechanism to reduce the heat convection loss of the trolley furnace, thereby realizing the efficient heat preservation performance of the trolley furnace. The tempering trolley furnace adopts multi-zone heating, and the stainless steel thermal circulation fan is installed on the top of the furnace. The hot air is circulated at high speed. The hot air inner circulation stainless steel air guiding system uniquely designed by our heat treatment technology center is installed inside, and the temperature uniformity is very high.

Bogie hearth tempering furnace features:

1. The inside of the furnace is heated by the ocr25A/5 strip heating element.

2. The top of the furnace can be reciprocated by the high-pressure centrifugal fan through the air-conducting inner cover to make the furnace temperature uniform. An eccentric axial fan can also be used to recirculate the airflow in the furnace to achieve uniformity of furnace temperature.

3. The tempering furnace lining adopts an aluminum silicate fiber module structure. No heat storage, no gaps, insulation seal.

4. The furnace door is lifted up and down by an electric hoist. The principle of the spring lever presses the sealing furnace mouth by its own weight. Scientific and advanced.

5. The trolley is driven by an electric cycloidal pinwheel reducer with one or more sets of drive wheels and corresponding passive wheels on the inner and outer double tracks.

6. The furnace bottom heating element is coated with a steel plate bottom plate of ZG30Cr18Mm2sizN alloy. The upper block is superimposed between the block and the block to ensure that the scale does not fall into the heating element slot.

7. The thyristor is triggered by the PID intelligent zero-crossing. The programming instrument can be equipped with a 485 communication interface and connected to a computer for remote control. Cluster control. There is no paper recorder and paper recorder, over temperature alarm function.
