Yantai Dongruitai Welding and Cutting Equipment Co., Ltd. is one of the leading manufacturers and suppliers of heavy duty flame cutter in China. We are committed to providing high quality customized machines with low price. Welcome to wholesale the newest heavy duty flame cutter made in China here from our factory. 1 years warranty is available.
Different from standard automatic flame cutting equipment focused on lightweight batch processing, the heavy duty flame cutter is specially engineered for heavy-load, large-span and high-intensity industrial cutting scenarios. It adopts an integrally cast thickened gantry frame and stress-relief welding technology, effectively resisting mechanical fatigue and deformation caused by long-term heavy cutting operation. Professional oxy-fuel thermal cutting technology ensures high-quality molding of ultra-thick carbon steel plates, making it the core processing equipment for large steel structure factories and heavy machinery manufacturing enterprises.

Key Features & Industrial Advantages
This heavy-duty flame cutting equipment focuses on long-term operational stability, solving common issues of frame vibration, precision degradation, and inability to withstand prolonged heavy-load operations in ordinary cutting machines.
Anti-deformation frame:
The whole machine adopts thickened wall plate and integral stress-relief process. Even under long-term large-span reciprocating operation, the gantry remains stable without vibration or offset, maintaining cutting accuracy.
Professional thick plate cutting capability:
Optimized oxy-fuel flame ratio and high-pressure torch structure ensure smooth cutting sections for 6-200mm thick carbon steel, no slag hanging or excessive taper, reducing heavy polishing workload.
High-precision synchronous drive system:
Dual-side servo synchronous control realizes precise linkage, effectively avoiding diagonal deviation during large-format cutting and ensuring consistent dimensional tolerance of large workpieces.
Heavy-duty adaptive lifting structure:
300mm super-large lifting stroke adapts to uneven thick plate surfaces and height changes of super-thick workpieces, ensuring stable torch position during cutting.
Working Principle & Core Technology
This industrial cutting device adopts mature thermal oxygen cutting process. It uses high-temperature flame to heat the local part of carbon steel plate to combustion temperature, and uses high-pressure oxygen flow to blow away molten steel slag to form neat cutting seams. Equipped with intelligent constant-temperature flame control technology, it automatically adjusts flame power according to plate thickness changes, avoiding cutting penetration failure or over-burning defects. The high-rigidity gantry dynamic balance technology ensures no jitter during high-speed and long-distance travel, realizing high-precision heavy-duty cutting.
Application Scenarios
Targeting heavy industrial manufacturing fields that require large-format and super-thick plate processing:
Large steel structure engineering: Cutting of super-large structural plates, bridge steel plates and building support base plates.
Industrial-grade durable configuration: All core transmission and electrical components adopt industrial standard configuration, resisting high temperature and dust in heavy workshop environments, with ultra-long service life.
With ultra-wide processing span and super strong load-bearing capacity, the large flame cutting machine is perfectly suitable for one-time forming cutting of super-large and super-heavy steel plates that ordinary small cutting equipment cannot handle.
Heavy equipment manufacturing: Thick plate blanking for mining machinery, metallurgical equipment and large forging auxiliary parts.
Boiler and pressure vessel industry: Processing of thick-wall container steel plates and boiler tube sheet blanks.
Steel distribution & processing center: Bulk processing of various super-thick carbon steel profiles and large-format sheet parts.
Engineering machinery base production: High-precision cutting of thick steel base plates and load-bearing structural parts.
