Natural gas forging heating furnaces and heat treatment furnaces, with their advantages of high efficiency, energy saving, environmental protection, safe operation, long service life, and high cost-effectiveness, have been widely used in the forging and foundry industry, becoming important heating equipment in modern industrial production.
The heating furnace uses advanced internal heat storage technology, which recovers heat from high-temperature flue gas to achieve efficient energy recycling and utilization. This technology enables the furnace to achieve uniform heating, rapid temperature rise, and precise temperature control, effectively reducing temperature fluctuations, ensuring the quality of workpiece heating, and ensuring that nitrogen oxide (NOx) emissions fully comply with national and local environmental protection standards. Its high-efficiency and energy-saving features are particularly outstanding, with gas consumption per ton of steel about 50 cubic meters, reducing energy consumption by 20%-30% compared to traditional furnaces, significantly improving production efficiency and lowering operating costs.
Daqiu Forging Technology Co., Ltd. owns independently developed internal regenerative heating furnace technology, which works by recovering heat from high-temperature flue gas inside the furnace through efficient regenerative elements, while simultaneously preheating the auxiliary air and fuel, thereby maximizing combustion efficiency. Compared to traditional conventional combustion and external regenerative combustion technologies, internal regenerative combustion improves thermal efficiency to over 70%. By collaborating with well-known domestic universities to conduct industry-academia-research collaboration, process parameters and model heating curves are further optimized, ensuring simultaneous improvements in combustion uniformity and thermal efficiency, positioning regenerative heating furnaces at the forefront of high efficiency and energy saving.
The furnace is structurally designed with a reasonable design, mainly consisting of the furnace chamber, metal frame, burner, furnace door, flue, and pressure-regulating flue gate. The system operates stably and is simple and convenient to use. Natural gas and combustion air are thoroughly mixed in the high-efficiency burner before combustion. The generated hot gas flows rapidly and evenly heat the workpiece, while the exhaust gas is discharged through the flue, maximizing energy reuse through heat recovery. The furnace body has high structural strength and excellent durability, with a service life of over ten years and extremely low maintenance costs, truly achieving an organic combination of efficiency and reliability.
Natural gas chamber heat treatment furnaces are mainly used for stress relief and heat treatment heating of metal forgings, and are widely used in various heat treatment processes such as normalizing, annealing, quenching, tempering, and aging. This equipment uses precise temperature control technology to ensure uniform internal structure of forgings, meeting the mechanical properties and heat treatment quality requirements of different materials, and is widely used in high-end manufacturing fields such as automotive, aerospace, and petrochemicals.
With technological innovation and outstanding performance, Daqiu Forging Technology Co., Ltd.’s natural gas heating furnaces and heat treatment furnaces have become important supporting equipment for modern forging and heat treatment process upgrades, helping enterprises achieve energy saving, consumption reduction, green production, and efficient manufacturing, driving the industry toward higher quality and intelligence.
