Zinc pot slag cleaning device

Abstract

The invention relates to a zinc pot slag cleaning device, and belongs to the technical field of metallurgical equipment. The zinc pot slag cleaning device comprises a support frame with the top provided with a hanger, wherein the cylinder pedestal of a cylinder is hinged to the middle of the support frame, a straight-insert tong extending downward is fixed at one side of the bottom of the support frame, and a bent tong is hinged to the other side of the bottom of the support frame; the piston of the cylinder extends downward to form a push-pull rod, and the lower end of the push-pull rod is hinged to the a tong arm extending toward the direction of the straight-insert tong from the bent tong; the lower end of the bent tong is positioned in the opening position far from the lower end of the straight-insert tong when the piston of the cylinder is in a protruding state; and the lower end of the bent tong is positioned in the shut position with the lower end of the straight-insert tong when the piston of the cylinder is positioned in a retraction state. The zinc pot slag cleaning device can solve a problem that the blocky bottom slag of the zinc pot cannot be effectively cleaned, and can avoid the damages to the refractory material of the zinc pot when the slag cleaning efficiency and the cleaning effect are improved.

Description

technical field [0001] The invention relates to a device for cleaning slag in a smelting pot, in particular to a device for cleaning slag in a zinc pot, and belongs to the technical field of metallurgical equipment. Background technique [0002] In the cold-rolled hot-dip galvanized process, due to the chemical reaction between the aluminum-zinc metal and the plated metal (strip steel), the high-temperature oxidation of zinc, aluminum-zinc metal, and the peeling and corrosion of the refractory material in the zinc pot, the zinc in the zinc pot, Some solid particles are inevitably produced in the aluminum-zinc hot-dipping solution, which sink to the bottom of the zinc and aluminum-zinc solution in the zinc pot to form bottom slag. In recent years, in order to obtain better coating surface quality, the new hot-dip aluminum-zinc production process needs to add a small amount of rare earth elements and precious metals to the aluminum-zinc liquid in the zinc pot. Although this ha...

Problems solved by technology

This kind of slag cleaner has the following defects: 1) The symmetrical gripper X3 is only suitable for the removal of soft sandy slag, and the use effect of the hardened agglomerated zinc slag X5 with uneven surface is extremely poor; 2) The slag cleaner is in the During the slag removal process, the insertion depth of the gripper X3 depends entirely on the weight of the slag cleaner body, resulting in poor removal effect on hard zinc slag; 3) The symmetrical gripper is opened and the whole shape is a rectangular parallelepiped, while the coreless zinc sensor The inner cavity of the pot X4 is a cylinder, so that the zinc slag on the edge of the zinc pot cannot be effectively removed; 4) The position and depth of the zinc pot inserted into the zinc pot are completely controlled by the crane through the upper lug, and the positioning accuracy is poor and the speed is slow. The shape of the zinc pot is very easy to cause collision damage to the inner wall of the zinc pot and the bottom refractory material X6 during the positioning process

[0004] Chinese patents with application numbers 200920316918.1 and 200920177287.X respectively disclose a zinc pot hydraulic slag removal device and a slag removal device, both of which fail to overcome the above-mentioned defects. There is a big safety hazard in the use of pots in high-temperature areas

The Chinese patent with the application number 201010125464.7 discloses a device for removing zinc dross in the galvanizing pot of the galvanizing line, which is only suitable for removing surface dross, not for removing bottom dross
