In the production of high-grade galvanized automobile plates, the traditional slag-discharging furnace nose is difficult to discharge fine zinc ash in time due to insufficient zinc liquid overflow fluidity on the two sides and the lower surface of strip steel, so that the defects of zinc ash such as slag spot and the like are generated, the condition is particularly prominent in the production of wide-width galvanized plates, and the annular overflow (double-sided overflow) furnace nose is produced. The furnace nose zinc liquid has good fluidity and good ash discharge effect, and has good effects of improving the quality of a wide-plate hot-dip galvanized GI outer plate and reducing the defect of zinc ash point slag. In order to facilitate online position adjustment, the annular overflow (double-sided overflow) furnace nose usually adopts a split structure, and the lower part of the furnace nose body is connected with a cofferdam structure capable of adjusting the plane precision of an overflow lip, namely a so-called furnace nose tundish. The tundish is a cofferdam structure formed by thin plates and used for isolating the inner liquid level and the outer liquid level of the zinc pot, and when the zinc pump works, the zinc liquid at the inner liquid level of the zinc pot overflows into the annular groove and is discharged into the zinc pot outside along with the zinc pump. The tundish is connected with the furnace nose body through four studs, so the position of the tundish and the position of a zinc pump and the outlet of a tundish pipeline are required to be unified.
The annular overflow furnace nose has higher requirements on the stability and uniformity of the flow of the zinc liquid on two sides of the strip steel, the general fluctuation cannot be larger than 1mm, otherwise, the overflow ash discharge cannot meet the requirements. The overflow precision of the furnace nose is closely related to the manufacturing precision of the tundish, and how to ensure the flatness of the lip of the tundish and the position degree of the zinc pump plays an important role in improving the overflow precision of the furnace nose and the interchangeability of the tundish. Therefore, the research on the manufacturing method of the annular overflow furnace nose has important significance for improving the quality of annular overflow (double-sided overflow) of the furnace nose and improving the overflow ash discharge effect of the tundish.
