Abstract

The invention discloses a continuous heating and spraying system of metal pipes and an application method thereof, and belongs to the technical field of heating and spraying of metal heat exchange pipes. The continuous heating and spraying system of the metal pipes comprises a rotating mechanism, a heating mechanism, a spraying mechanism, a support mechanism, a moving mechanism and a support rod; the support rod penetrates through the heating mechanism; the spraying mechanism is arranged on the heating mechanism; two ends of the support rods are positioned above the rotating mechanism; the support rod is coated with a metal pipe; and the support mechanism for supporting the support rod and the moving mechanism for pushing the metal pipe are arranged below the support rod. The continuous heating and spraying system of the metal pipes is mainly used for realizing a continuous heating and spraying process of the metal pipes.

Description

technical field [0001] The invention relates to a metal tube spraying device, more specifically, to a metal tube continuous heating spraying system and its use method, belonging to the technical field of heating spraying of metal heat exchange tubes. Background technique [0002] Metal heat exchange tubes (bare tubes, finned tubes, etc.) are important heat exchanger components for strengthening the utilization of waste heat and energy in the steel industry and for deep waste heat recovery. The quality of metal heat exchange tubes directly affects the heat exchange of heat exchangers. effect and the service life of the heat exchanger. At present, in the process of recovering low-temperature flue gas or gas waste heat, the heat exchanger mainly has the problems of ash, bonding and corrosion on the surface of the metal heat exchange tube. Taking the recovery of waste heat from blast furnace gas in a steel plant as an example, the temperature generated from the blast furnace is ...
