Device and method for removing slag on surface of plating liquid

Abstract

The invention relates to a device and a method for removing slag on the surface of plating liquid in a medium and small-sized crucible furnace. Four motors (1-1, 1-2, 1-3 and 1-4) which are distributed symmetrically penetrate through drivers (2-1, 2-2, 2-3 and 2-4) of a sealing device (7) respectively under the control of an electrical control system (9) and are connected with a slag stopper (11), a first side surface slag pusher (12), a second side surface slag pusher (13) and an opposite surface slag pusher (14); and the slag pushers move back and forth towards the slag stopper so as to remove the slag on the surface of the plating liquid. The slag on the surfaces of plating liquids of pure aluminum, aluminium-silicon, aluminum-zinc-silicon, zinc-aluminum, aluminum, zinc-magnesium-aluminum, pure zinc plating liquid and the like are accurately removed due to the joint running of the electrical control system, the motors, the slag pushers and the slag stopper, thus the amount of the slag on the surface of the plating liquid is reduced to the maximum extent, the quality of the surface of the plated layer is improved and the points which are not plated are reduced.

Description

technical field [0001] The invention belongs to the field of equipment used in a hot-dip plating process that uses a molten coating material without affecting the shape, and specifically relates to a device and method for removing liquid slag on the surface of a plating solution. Background technique [0002] In the process of production and experimentation, the plating solution in the crucible furnace is a huge reactor, and there are input and output of substances, and input and output of heat. Plating solutions such as pure aluminum, aluminum-silicon, aluminum-zinc-silicon, zinc-aluminum, zinc-aluminum-magnesium, and pure zinc will all react with oxygen in the atmosphere to form oxides, which will agglomerate into liquid slag on the surface of the plating solution. For example, for galvanizing production lines and laboratories, even under a certain protective atmosphere, the iron elements on the surface of the steel plate will still dissolve into the pure zinc plating solu...

Problems solved by technology

At the same time, because liquid slag exists on the surface of the plating solution and is in a floating state, the product is easily stained with a certain amount of liquid slag during the process of entering and leaving the plating solution, resulting in defects such as dots, lines, and patterns on the surface of the product. , which reduces the surface quality of the product, and is also likely to cause partial missing plating

[0003] At present, my country's hot-plating production lines and laboratories lack devices and methods for removing slag from the plating solution. Generally, the method of manually removing slag is used. The liquid slag on the surface is picked up, which has the disadvantages of low slag removal efficiency, high cost, and poor safety of personnel operation, and it is impossible to carry out slag removal work in a certain atmosphere

At the same time, foreign plating solutions also use manual slag removal, which is not only inefficient, but also cannot guarantee safety and slag removal rate.
