Abstract

The invention discloses an automatic zinc pot outer boiler wall waste heat heater, and belongs to the technical field of hot dipping process equipment. The automatic zinc pot outer boiler wall waste heat heater solves the problems that in the prior art, a zinc pot heater is poor in heating effect, consequently, the temperature of molten zinc is not uniform, cooling is fast, and the galvanizing effect is affected. The automatic zinc pot outer boiler wall waste heat heater comprises multiple sets of heating pipes, wherein the heating pipes are connected with the outer wall of a boiler, the heating pipes are in continuous U shapes, the cross sections of the heating pipes are semicircular, heat conduction fins are installed in the heating pipes, the heat conduction fins are connected with the outer wall of the boiler, the heat conduction fins are arranged perpendicular to the surface of the outer wall of the boiler, the multiple sets of heating pipes are arranged on the outer wall of the boiler, a series connection pipeline is connected between the heating pipes, one end of the heating pipes is connected with a water inlet pipe, and the other end of the heating pipes is connected with a water outlet pipe. Water in the heating pipes directly makes contact with the outer wall of the boiler, in cooperation with the heat conduction fins, high-efficiency heat transfer heating is achieved, waste heat of the outer boiler wall of the zinc pot is fully utilized, and energy is saved.

Description

technical field [0001] The invention belongs to the technical field of hot-dip plating process equipment, and in particular relates to an automatic heater for waste heat on the outer furnace wall of a zinc pot. Background technique [0002] Galvanizing refers to a surface treatment technology that coats a layer of zinc on the surface of metals, alloys or other materials for aesthetics and anti-rust effects. The main method used is hot-dip galvanizing. [0003] Zinc is easily soluble in acid and alkali, so it is called amphoteric metal. Zinc hardly changes in dry air. In humid air, a dense basic zinc carbonate film will be formed on the surface of zinc. In the atmosphere containing sulfur dioxide, hydrogen sulfide and marine atmosphere, the corrosion resistance of zinc is poor, especially in the atmosphere of high temperature, high humidity and organic acid, the zinc coating is easily corroded. The standard electrode potential of zinc is -0.76V. For the steel substrate, t...
