Background
The modern continuous hot galvanizing production line for strip steel is the infrastructure of cold rolling mill to produce high quality galvanized sheet for building, household appliance and automobile. With the development of coating technology, the quality requirements on the galvanized sheet for buildings, household appliances and automobiles are higher and higher. Besides the direct relationship between the surface quality of the steel plate and the surface roughness and the cleanliness of the thin plate and the chemical components of the strip steel, the hot-dip coating process, the components of the zinc liquid and the hot-dip coating equipment are also important factors influencing the surface quality of a coating. In a zinc pot for hot-dip pure zinc plating and hot-dip alloying zinc liquid, most of surface defects are related to zinc dross, and the zinc dross is easily adhered to a galvanized steel sheet in the galvanizing process, so that the zinc dross defects are formed, and the appearance quality of the galvanized steel sheet is seriously influenced. Therefore, the zinc dross in the zinc liquid is the most important factor influencing the surface quality of the galvanized sheet.
The liquid metal electromagnetic separation mechanism is that the heterogeneous particles can be separated from the metal liquid under the action of an electromagnetic field by utilizing the poor conductivity between the metal liquid and the heterogeneous particles, and the separated particles are removed through the fixation and capture effects of a medium, so that the electromagnetic purification of the metal liquid can be realized.
At present, after an intermediate test for separating zinc slag by applying an electromagnetic separation mechanism is completed, natural cooling is usually performed, as the size of a zinc container is far larger than that of a crucible, the zinc container cannot be reused, zinc liquid in the zinc container must be scooped out into a smaller container, so that the zinc liquid can be reused in the next test, and if the zinc liquid is not properly scooped, the zinc liquid in a scoop is dropped, so that the dropping safety accident is easy to happen, and personal injury is caused; the natural cooling speed is slow, the cooling time is too long, and the working efficiency is low; and the zinc ingot is too big in size and can not be reused, and meanwhile, in the natural cooling process of the zinc liquid, adhesive force is formed between the zinc ingot and the container, so that the zinc ingot can not be smoothly pulled out after being cooled.
