How to improve the quality and performance of multi-purpose furnace radiant tubes?

Multi-purpose furnace tube cores are cage-framed, vertical-wound, and resistance wire-wrapped. The resistance wire is made of nickel-chromium and iron-chromium-aluminum alloy materials. General effective length: 900 ～ 2400; outside diameter of general casing: φ80 ～ φ280. Single power: 2kw ～ 40kw; single voltage: 30v ～ 220v.

This series of products are suitable for multi-purpose furnaces that perform bright fire, normalizing, carburizing, and carbonitriding, as well as industrial heating such as swivel, mesh belt, casting, and continuous.

Multi-purpose furnace radiant tube heating device is mainly composed of radiant tube body, heat exchanger and burner. The multi-purpose radiant tube body is a key component that radiates the heat energy released by the combustion of fuel to the steel strip. Among them, U-shaped radiant tubes with waste heat recovery devices are widely used in horizontal heat treatment furnaces; heat exchangers are the two major radiant tube heating devices. One of the core components, its main function is to improve the overall life of the radiant tube. Its temperature needs to reach the highest possible air preheating temperature and the lowest possible flue gas discharge temperature, and reduce the resistance loss of the preheated air. The radiant tube is not harmed by the environment, thereby increasing the life of the radiant tube. The burner is another core component of the two cores of the radiant tube heating device. It controls the power, thermal efficiency, temperature distribution of multi-purpose radiant tube heating and grasps the radiation. Tube life.

Today's industrial progress has higher requirements for related equipment, and the market demand for multi-purpose radiant tubes is also increasing. To improve the quality of multi-purpose radiant tubes, efforts must be made from these components, and only the performance of the components must be guaranteed. Good, can improve the performance of multi-purpose radiant tube.
