A , heating process and technical requirements

1 Use: matched with 2500 ton press, forging the billet of the front axle of the automobile;

2 workpiece material: medium carbon steel

3 Heating temperature: 1250 ° C

4 Temperature difference requirements: radial temperature difference ≤ 60 ° C, first and last temperature difference ≤ 80 ° C;

5 heating part: overall heating

6 Typical blank size:

B. Overview of the overall design plan:

1. Power: The total frequency of 2 medium frequency heating furnaces is 1000KW, and the nominal frequency is 500hz.

2. Configure the sensor model and structure: GTR-190×2500, the basic parameters are as follows:

3. Furnace structure: The furnace body is made into double working position, each station is 500kw, combined heating, they are staggered by one time beat, complementary feeding, alternating discharging, combined heating time of 180 seconds, when running alone The beat is 360 seconds.

4. Material preparation method: The ground hoist is used to lift the blank to the storage rack. The storage bin can store 4 materials at a time;

5. Feeding mode: using cylinder pushing material, step feeding method;

6. Discharging method: the discharging end uses roller conveyor to pick up the blank;

7. Temperature detection and sorting: The infrared burner is equipped with an infrared thermometer to perform three-point selection on the ultra-high temperature, ultra-low temperature and normal temperature of the billet.

8, the overall structure as shown in the figure:
