Coal mining pick/drill bit induction brazing complete equipment

The welding and quenching of the shearer picks can complete the compounding process at one time: first put the tooth body into the coil of the induction heating device to heat and weld the carbide cutter head, the frequency range is 15-25KHZ, the temperature is 840-920 ℃, and the temperature is constant. The time is 5-10 minutes, and then directly put the welded tooth body with the cutter head into the nitrate salt tank at 260—290°C for quenching and cooling, and the composite process can be completed. The main advantage of this process is that it does not need to add salt. The heating process of the bath furnace improves the toughness of the cutter head, prolongs its life, improves work efficiency, reduces power consumption, and reduces equipment investment.

The main components of the coal mining pick/drill bit induction brazing complete set of equipment:

1) The automatic conveying material structure is composed of: frame, speed control motor, sprocket, chain, asbestos plate, stainless steel bracket, speed regulator, electrical control, etc.

2) Intermediate frequency power supply composition: 200KW main control cabinet, special furnace for pick welding process, etc.

(3) The composition of the nitrate furnace: stainless steel plate or ordinary steel plate as the inner tank, insulation layer, outer shell, transmission mechanism, melting nitrate heating part, cooling part, stirring device, temperature control device, electrical control, material hook, etc.

Energy saving effect of coal mining pick/drill bit induction brazing power supply

Shift production of 10 tons of forgings saves 80-100 kWh per ton, and the shift saves 560-700 yuan in electricity costs; monthly electricity costs are saved by more than 20,000 yuan; double-shift or three-shift production, monthly electricity costs are saved by more than 40,000-60,000 yuan. The equipment investment can be recovered within a few months.

Features of coal mining pick/drill bit induction brazing complete set of equipment:

⑴The comprehensive mechanical performance of the pick body is stable and the strength is high;

⑵The welding seam is full and full, the appearance is exquisite, and the welding strength is high;

⑶ Save labor and time, only need two people to load and unload, and operate a complete set of equipment;

⑷ Save electricity, saving more than 30% of electricity compared with traditional technology;

⑸Improve efficiency: different models can produce 4-6 finished picks per minute;
