Welding preheating of the middle groove of the scraper machine
The direct discharge multi port heating torch is mainly designed for heating thick plates before welding to prevent hydrogen induced cracking. The cross arrangement of fire ports can effectively cover both sides of the weld seam, ensuring uniform heating around the weld seam and improving welding quality. It can also be used in conjunction with automated welding lines.

Preheating of hydraulic support fillet welds before welding
Install two single head heating torches at the front end of the automatic welding of the fillet weld, and heat the diagonal weld to quickly raise the temperature on both sides of the weld to 120-180 ℃ to prevent hydrogen induced cracking during the welding process.

Welding preheating of the digging head tool holder
The direct discharge multi port heating torch is mainly designed for heating thick plates before welding to prevent hydrogen induced cracking. The fire can be evenly distributed around the knife holder, ensuring that the knife holder is evenly heated. Simultaneously, welding and preheating can be synchronized.

Water cooled quenching of scraper chain wheel
The water-cooled quenching gun is mainly used for surface hardening treatment of shafts, keys, and friction positions between sprockets and circular chains. By controlling the quenching time, different thicknesses of hardened layers are achieved.

Flame heating platform
The flame heating platform is mainly used for cutting wear-resistant steel plates and preheating before welding to prevent the generation of hydrogen induced cracks. The heating platform can evenly heat the entire steel plate interface to avoid local overheating in the area in contact with the heat source. The maximum temperature at which the steel plate is heated should not exceed 220 ℃, otherwise the crystal structure of the wear-resistant steel plate will be changed.

Preheating for middle groove plate welding
The middle groove plates need to carry ore or coal from the pit bottom to the ground, so the welding of the groove plates and the edge plates must be strong and impact resistant. We design and manufacture a double-row flame heating platform specifically for preheating the grooved and edge plates.
