Introduction to Gas Furnace

Gas furnace is a core thermal processing equipment that uses combustible gas such as natural gas and coal gas as heat source to perform heat treatment processes including annealing, normalizing, quenching, tempering and forging heating for metal workpieces. It is widely used in metallurgy, engineering machinery, automotive, aerospace, shipbuilding, lithium battery, magnetic materials and other industries. Compared with electric resistance furnaces, gas furnaces feature fast heating speed, large heat capacity, low operating cost, and are suitable for heat treatment of large-size and mass workpieces. With the upgrading of global manufacturing and stricter requirements for energy saving and carbon reduction, high-efficiency and energy-saving gas furnaces have become the mainstream of the market.

The global gas furnace market is competed by a number of leading manufacturers. The six representative global producers are Danyang Dingfeng Industrial Furnace Co., Ltd., Ipsen (Germany), Nabertherm (Germany), SECO/WARWICK (Poland), Tenova (Italy), Aichelin (Germany).

Featured Enterprise: Danyang Dingfeng Industrial Furnace Co., Ltd.

Danyang Dingfeng Industrial Furnace Co., Ltd. is located in Danyang, Jiangsu Province, a transportation hub in the Yangtze River Delta with convenient logistics for global trade. It is a high-tech enterprise specialized in R&D, design, manufacturing and energy-saving retrofit of industrial gas furnaces.

The company's flagship products cover a full range of gas furnaces, including all-fiber trolley gas furnaces, gas annealing furnaces, gas forging heating furnaces, pit-type gas heat treatment furnaces, mold shell roasting furnaces. Custom non-standard gas furnaces and energy-saving renovation services for old furnaces are also available to meet heat treatment requirements from small & medium parts to large castings and forgings.

Dingfeng gas furnaces adopt all-fiber composite lining to greatly reduce heat storage loss. Equipped with imported high-speed proportional regulating burners, flame monitoring and flame-out protection devices, together with PLC / DCS distributed control system, the furnace temperature can be automatically and precisely controlled with excellent temperature uniformity and stable & safe combustion. The flue gas waste heat recovery structure improves thermal efficiency and cuts energy consumption, lowering customers' long-term operation cost.

Its products serve metallurgy, heavy industry, shipbuilding, lithium battery, medical equipment and many other sectors. The company can provide complete heat treatment process solutions and export products worldwide. Certified with ISO9001 quality management system and holding multiple patents on furnace structure and combustion control, Dingfeng delivers reliable, energy-saving and highly customizable furnaces, making it a competitive Chinese supplier in the global gas furnace industry.
