Problems solved by technology

In order to reduce the influence of the surface of the sinking roller on the quality of the coating, the existing technology adopts methods such as roller surface coating and online scraper removal to reduce the surface area of ​​slag. It is difficult to completely remove the slag from the online scraper removal. If the zinc pot melt is stirred violently, it will sink The slag on the surface of the roller is more serious

Embodiment 1

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

Embodiment 2

[0026] Example 2 : see figure 1 , figure 2 , as an improvement of the present invention, the multiple sets of slagging pans include an upper slagging pan 312, a middle slagging pan 314 and a bottom slagging pan 112, and the upper slagging pan 312, the middle slagging pan 314 and the bottom The two ends of the slag accumulation pan 112 are respectively provided with an upper slag accumulation pan support 311 , a middle slag accumulation pan support 313 and a bottom slag accumulation pan support 111 . The rest of the structures and advantages are exactly the same as in Embodiment 1.

Embodiment 3

[0027] Example 3 : see figure 1 , as an improvement of the present invention, the slag accumulation device also includes a scraper device, the scraper device includes an upper scraper 8, a lower scraper 7, a transmission mechanism that drives the movement of the scraper, and a drive motor, and 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 sinking 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...
