TECHNICAL FIELD
[0001] The utility model relates to zinc alloying process equipment technical field, concretely relates to a furnace cover for multielement alloy zinc alloying furnace. BACKGROUND
[0002] Zinc alloying technology is a new method for preventing rust and corrosion by using the principle of metal atom diffusion under heat, making zinc powder contact with metal workpieces below the melting point to form a zinc-iron alloy protective layer on the surface of the metal workpieces to prevent atmospheric corrosion. During work, the metal workpieces, zinc powder, quartz sand and a plurality of permeation aids and other materials are mixed together and placed in a sealed container, heated at a predetermined process temperature and kept for a certain time, so that zinc atoms penetrate from the surface of the metal workpieces to the inside, while iron atoms diffuse from the inside to the outside, forming a uniform zinc-iron compound layer on the surface of the metal workpieces, i.e. a zinc alloying layer, which realizes cathodic protection of the metal workpieces through the zinc alloying layer.
[0003] At present, the powder zinc alloying treatment of the surface of the metal workpieces mainly involves loading the metal workpieces, zinc powder, quartz sand and various permeation aids into a sealed rotatable furnace barrel, then hoisting the sealed furnace barrel into the zinc alloying furnace body, and then reacting the pure iron products + zinc powder + quartz sand + some other catalysts or aids in a vacuum environment, so that zinc penetrates into iron, and the reaction is carried out in the furnace barrel. One end of the shaft at both ends of the furnace barrel is provided with an explosion-proof valve, and the other end is provided with a gas inlet and outlet hole for vacuum pumping or inert gas injection. The furnace bottom base is heated, and the two ends are provided with driving devices to drive the end shafts at both ends of the furnace barrel to rotate and heat, so as to heat the furnace barrel. A furnace cover is arranged above the furnace. After being treated at a predetermined temperature for a predetermined time, the heating element is turned off, the furnace barrel is cooled to a predetermined temperature, the furnace cover needs to be opened, then the furnace barrel is hoisted out, and finally the treated workpieces are taken out from the furnace barrel. However, the existing furnace cover needs to be hoisted by a workshop overhead crane device, and since the temperature in the furnace and the furnace cover is high, hoisting the furnace cover by the overhead crane has the problems of long operation time, low efficiency, and danger to the workers below who operate the workpieces in the furnace barrel. Therefore, there is an urgent need for a multielement alloy zinc alloying furnace which is reasonable in design, simple in structure and can quickly realize automatic opening of the furnace cover, to solve the problem that has plagued technicians in the field in the prior art.
