Problems solved by technology

In the harsh environment of high temperature on the zinc pot and full of zinc powder and impurities, the structure of the screw nut is worn out quickly, and the life is very low. Production often leads to failures due to abnormal wear of the nut, and every time the nut is repaired and replaced. The transmission structure must be completely dismantled, and the workload is very heavy, which seriously affects the normal production

Embodiment 1

[0028] Such as figure 2 As shown, the steel strip 1 goes deep into the zinc pot 2 after being sent out from the return furnace, and the zinc pot 2 is filled with molten zinc liquid with a temperature as high as 450°C to 600°C, the sinking roll 31, the stabilizing roll 32 and the correction roll 33 and All submerged in the zinc liquid; after the strip steel 1 is immersed in the zinc liquid surface, zinc is adhered to the surface, and then the strip steel 1 is attached to the roller surface of the sinking roller 31 and passed through the zinc liquid surface by the sinking roller 31 turning upward; the zinc liquid surface An air knife 34 is respectively arranged on both sides of the upper strip steel 1, and the blowing ports of the air knife 34 are respectively facing one surface of the strip steel 1, and the zinc pot 2 is provided with a stabilizing roller 32 and a correcting roller 33, and the stabilizing roller 32 and the correcting roller The rollers 33 are arranged on both ...

Embodiment 2

[0042] A roller scraper for hot-dip galvanizing, including a sinking roller scraper arm 41, a sinking roller scraper blade 42, a stabilizing roller scraper arm 51, a stabilizing roller scraper blade 52, a beam 6, a linear guide rail 61, a moving trolley 7, and a traveling mechanism 71, telescoping mechanism 72, hinge point 73, reciprocating propulsion mechanism 74, scraper lever 8 and flange 9, such as Figure 4 Shown, concrete structure is: reciprocating propulsion mechanism 74 selects propelling cylinder 747 for use, and the outer end of propelling cylinder 747 piston rods is the reciprocating propelling end of reciprocating propulsion mechanism 74, drives mobile dolly 7 along linear guide rail 61 by the expansion and contraction of propelling cylinder 747 piston rods Move back and forth.

[0043] Other structures and usage methods are all the same as in Embodiment 1.

Abstract

The invention relates to the field of roller system cleaning equipment in the production of cold-rolled steel strips, nonferrous sheet metal and paper and particularly relates to a roller system scraper for hot galvanizing. The roller system scraper for hot galvanizing comprises a sink roller scraper arm (41), a sink roller scraper blade (42), a stabilizing roller scraper arm (51) and a stabilizing roller scraper blade (52) and is characterized by also comprising a cross beam (6), a linear guide rail (61), a moving trolley (7), a walking mechanism (71), a telescopic mechanism (72), a hinge point (73), a reciprocating feed mechanism (74), a scraper lever (8) and a flange (9), wherein the cross beam (6) is sheathed by the moving trolley (7); and the walking mechanism (71), the telescopic mechanism (72), the hinge point (73) and the reciprocating feed mechanism (74) are arranged on the moving trolley (7). The roller system scraper provided by the invention has the advantages of simple structure, high safety and reliability, thorough scraping effect, strong environmental adaptability and long service life.

Description

technical field [0001] The invention relates to the field of roll system cleaning equipment in the production of cold-rolled strip steel, non-ferrous metal plates and papermaking, in particular to a roll system scraper for hot-dip galvanizing. Background technique [0002] When the hot-dip galvanizing unit is running, such as figure 1 As shown, the steel strip 1 needs to go deep into the zinc pot 2 after being sent out from the return furnace, and the zinc pot 2 is filled with a molten zinc liquid with a temperature as high as 450°C-600°C, and the zinc liquid is composed of about 97wt% Zn and 3wt% Composition of left and right Al, the sinking roll 31, the stabilizing roll 32 and the correction roll 33 are all immersed in the zinc liquid; after the strip steel 1 is immersed in the zinc liquid surface, zinc is adhered to the surface, and then the strip steel 1 is attached to the roll surface of the sinking roll 31 And turn to rise by sinking roller 31 and pass through from th...
