GHDG-800 고정 플래시 맞대기 레일 & 투표율 용접기에는 높은 DC 전원 공급 장치가 장착되어 있습니다.. 그것은 짧은 레일을 용접하기 위해 고정 플랜트에서 사용하도록 설계되었습니다. 500 미터 이상, 뿐만 아니라 레일에 대한 투표율 (such as high-manganese steel frogs) and large alloy parts. This versatile welding machine can weld any type of rails and frogs, ensuring accurate alignment and preventing rail slippage during the upset forging process. It also provides stable and uniform power supply performance. The GHDG-800 can be configured for continuous welding, pulsation welding, and preheating welding processes.
파트 A: Basic Information
The machine consists of various components including a water-cooling system, 유압 시스템, 용접 주회로, 전기 제어 시스템, 용접 헤드, software system, and other parts.
파트 B: Scope of Application
This welding machine is primarily used for flash butt welding of large profiles, especially for welding turnouts and rails.
파트 C: How It Works
The welding machine features four independent clamping devices that accurately hold irregularly shaped workpieces in a horizontal position. It also has a centering function to adjust the relative position of the workpieces for precise butt welding. 용접 중, a strong DC current is supplied through the clamping electrode to reduce welding resistance. Once the welding surface reaches the required temperature, upsetting is performed to complete the welding process. The upsetting mechanism ensures even distribution of forging pressure for precise welding.
파트 D: Welding Range
The GHDG-800 is capable of welding turnouts and rails that comply with national standards in China, the European Union, 러시아, 미국, and other countries. This includes various combinations such as rails and rails, and rails and turnout frogs with austenitic or high-manganese steel spacers. The machine can weld cross sections up to 16,000 mm2 with a tensile strength of 800-1300 해당 없음 / mm2. The welding efficiency can reach a maximum of 20 joints per hour.
