Example Embodiment

[0025] Example 1 : See figure 1 , figure 2 , A continuous hot-dip plating sink roller slag accumulation device, the slag accumulation device includes a sink roller 1, a stabilizer roller, the stabilizer roller includes an upper stabilizer roller 3 and a lower stabilizer roller 2, the upper stabilizer roller 3 is fixed on the On the stabilizing roller cantilever 31, the sinking roller 1 is fixed on the sinking roller cantilever 11, the upper stabilizing roller cantilever 31 is provided with multiple sets of slag accumulation discs, and the multiple sets of slag accumulation discs form a fence, and the slag accumulation discs are located Between the sink roller 1 and the upper stabilizer roller 3. The multiple sets of slag accumulation discs set up in this technical solution form a fence, which can reduce the strong agitation of the local melt above the sinking roller, facilitate the deposition of zinc slag, can significantly reduce or eliminate the surface slag of the sinking ...

Example Embodiment

[0026] Example 2 : See figure 1 , figure 2 As an improvement of the present invention, the multiple sets of slag accumulation trays include an upper slag accumulation tray 312, a middle slag accumulation tray 314, and a bottom slag accumulation tray 112. The upper slag accumulation tray 312, the middle slag accumulation tray 314, and the bottom Two ends of the slag accumulation tray 112 are respectively provided with an upper slag accumulation tray support 311, a middle slag accumulation tray support 313, and a bottom slag accumulation tray support 111. The rest of the structure and advantages are exactly the same as the first embodiment.

Example Embodiment

[0027] Example 3 : See figure 1 As an improvement of the present invention, the slag accumulation device further includes a scraper device. The scraper device includes an upper scraper 8, a lower scraper 7, and a transmission mechanism and a drive motor that drive the movement of the scraper. The upper scraper 8 is located on the upper stable Above the roller cantilever 31, the lower scraper 7 is located at the lower part of the submerged roller cantilever 11.

Abstract

The invention relates to a continuous hot dipping sink roll slag deposition device which is characterized by comprising a sink roll and a stabilizing roll, wherein the stabilizing roll comprises an upper stabilizing roll and a lower stabilizing roll; the upper stabilizing roll is fixed to an upper stabilizing roll cantilever; the sink roll is fixed to a sink roll cantilever; the upper stabilizing roll cantilever is provided with a plurality of slag deposition disks; and the slag deposition disks form a barrier, and are positioned between the sink roll and upper stabilizing roll. The slag deposition disks are covered on most upper surface of the sink roll; when the zinc pot melt is stirred and flows, zinc slag in the melt preferentially deposits in the slag deposition disks, and large-granule zinc slag which is scraped by the upper stabilizing roll scraper on line preferentially deposits in the slag deposition disks; and the slag deposition disk structures form the barrier, and can reduce the severe stirring of the partial melt above the sink roll, thereby being beneficial to deposition of the zinc slag, obviously reducing or eliminating the slag deposited on the sink roll surface and enhancing the coating surface quality.

Description

technical field [0001] The invention relates to a slag accumulating device, in particular to a slag accumulating device and a slag accumulating method for a sinking roll of continuous hot dip coating. Background technique [0002] Continuous hot-dip coating includes galvanized, galvanized, aluminum-coated, galvanized aluminum-magnesium and other coating technologies. The sinking roller is a key component of continuous hot-dip galvanizing production. Due to the harsh working environment, when hot-dip galvanizing, aluminum-plating, galvanized aluminum-magnesium and other coatings, there are many micron and millimeter-sized high-melting point zinc dross in the zinc pot , It is easy to accumulate slag on the surface of the sinking roller. The sinking roll is in direct contact with the surface of the steel strip, and the slag on the surface of the sinking roll has a great influence on the quality of the coating. In order to reduce the influence of the surface of the sinking rol...
