Problems solved by technology

[0004] Aiming at the disadvantage that the scraper of the traditional ordinary zinc pot sinking roller cannot discharge the scraped zinc slag out of the "V" area, the invention designs a zinc pot sinking roller with a double-layer blade structure and can automatically collect the scraped zinc slag The scraper greatly improves the slag scraping effect of the sinking roller of the zinc pot

Embodiment Construction

[0013] refer to image 3 and combine Figure 4 As shown, the scraper 15 of the zinc pot sinking roller includes a "bow" shaped cavity structure 10, an upper piece and its base 8, a lower blade and its base 7, a "V"-shaped fixed bracket 11, a filter residue plate 9, and an installation base 12, coupling shaft 13, knife arm 14. The cutter body adopts a "bow"-shaped cavity structure 10, and the arc of the "bow"-shaped structure 10 matches the curvature of the surface of the sunken roll of the zinc pot to be cleaned. The base is connected by a sleeve shaft, and the upper and lower double scraper blades are set on the "bow" cavity structure. Two filter residue plates 9 are arranged on both sides of the structure. The zinc pot submerged roller scraper installs the upper blade and its base 8, the lower blade and its base 7 on the concave surface of the "bow"-shaped cavity structure 10 through the fixing nut, and the stainless steel gasket can be added during the installation test....

Abstract

The invention relates to tools for cleaning the surfaces of rolls, in particular to a scraper for sink rolls in zinc pots. The scraper for the sink rolls in the zinc pots mainly solves the technical problem that a traditional common scraper for sink rolls in zinc pots is incapable of discharging scraped zinc dross out of a 'V' area. The technical scheme includes that the scraper for the sink rolls in the zinc pots is characterized in that a scraper body is of an 'arch'-shaped cavity structure, the radian of the 'arch'-shaped structure matches with that of the roll surface of a cleaned sink roll in a zinc pot, the 'arch'-shaped structure is in sleeve connection with a scraper base through a 'V'-shaped fixing support and provided with an upper scraper blade and a lower scraper blade, dross guide holes in two rows are arranged on a recessed surface of the 'arch'-shaped cavity structure with the blades mounted thereon, and two dross filtering plates are arranged on two sides of the 'arch'-shaped structure. The scraper for the sink rolls in the zinc pots is mainly used for cleaning bonded dross on roll surfaces of the sink rolls, stabilizing rolls and the like in the zinc pots in cold-rolled hot galvanizing and hot-dipped aluminum-zinc production processes.

Description

technical field [0001] The invention relates to a tool for cleaning the surface of rolls, in particular to a scraper for zinc pot sinking rolls, which is mainly used for cleaning the surface of sinking rolls, stabilizing rolls, etc. Slagging. Background technique [0002] Due to the chemical reaction between zinc, aluminum-zinc metal and the plated metal (strip steel), the high-temperature oxidation of zinc, aluminum-zinc metal, and the peeling and corrosion of zinc pot refractory materials in cold-rolled hot-dip galvanizing and hot-dip aluminum-zinc processes, etc., Some fine solid particles are inevitably produced in the zinc and aluminum-zinc hot-dipping solution in the zinc pot, which are composed of intermetallic compounds, metal oxides, and non-metal oxides. Under the stirring effect of the zinc pot induction heating electromagnetic field, these fine solid particles sink to the bottom of the zinc and aluminum-zinc solutions in the zinc pot to form bottom slag (mainly ...
