Abstract
The utility model discloses a zinc snout in a cold-rolled steel belt galvanizing bath, which comprises an upper frame and a lower frame, wherein the upper frame is welded by stainless steel plates, a plurality of through holes are arranged in interval on the lower plane of the upper frame, and the lower frame is alumina porcelain material, and a plurality of stone bolts are arranged in interval on the upper plane of the lower frame, wherein the stone bolts of the lower frame are threaded into the through holes on the lower plane of the upper frame to connect the upper frame and the lower frame through nuts. The alumina porcelain material of the lower frame is cast, and the stone bolts are planted on the upper plane of the lower frame when casts alumina porcelain material. The utility model adopts alumina porcelain material to cast the lower frame of the zinc nose, and plants a plurality of stone bolts on the upper plane of the lower frame when casts, thereby connecting with the upper frame through the stone bolts. The zinc snout can not aggregate zinc in a galvanized bath owing to casting the lower frame of the zinc snout with alumina porcelain material, thereby avoiding the deformation of the zinc snout, guaranteeing the normal the cold-rolled steel belt galvanizing, and reducing maintenance frequency.
Description
Technical field
The utility model relates to the zinc nose in a kind of cold rolling mill steel band zinc bath.
Background technology
The zinc nose is the key equipment in the cold rolling mill steel band galvanizing process, and it mainly act as when avoiding cold-rolled steel strip zinc-plated, and the oxidation of zinc coating guarantees zinc coating quality.The work on the spot environment of zinc nose is very abominable, is in for a long time in the high temperature zinc bath.Though be not subjected to the effect of outside direct stress to the eye, the stress that complicated physics, chemical reaction produced that microcosmic takes place is to be difficult for more controlling.Usually the zinc nose in the cold rolling mill steel band zinc bath is that two frameworks are welded to form up and down, what adopt is the structural part of whole stainless steel plate as frame material, its underframe is the nose part of zinc nose, but stainless steel plate itself is the same with steel band, in zinc bath, also possesses galvanized ability, therefore as long as adopt steel plate as frame material, knot zinc is exactly inevitable outcome.Therefore the zinc nose distortion of nose partial corrosion can occur in the use at the scene, the zinc crystalline polamer appears in the stainless steel plate framework, increase along with the time, the thickening of knot zinc layer strengthens with the steel plate deformed amount, the gap that causes Galvanized Steel Strip to pass through reduces, even can damage Galvanized Steel Strip, so when maintenance, need move back reparations such as zinc, rectification distortion to the zinc nose, recover original state.So the zinc nose because stainless steel frame surface knot zinc causes the structural distortion of zinc nose, causes repairing the frequency height in use for some time, has a strong impact on normal production.
Summary of the invention
Technical problem to be solved in the utility model provides zinc nose in a kind of cold-rolled steel strip zinc bath, and this zinc nose can avoid tying zinc in the zinc bath of cold-rolled steel strip, guarantees that cold-rolled steel strip is galvanized normally to carry out, and has reduced repair rate.
For solving the problems of the technologies described above, zinc nose in the utility model cold-rolled steel strip zinc bath, comprise upper frame and underframe, described upper frame is that the stainless steel plate welding is made, the lower plane compartment of terrain of described upper frame has some through holes, described underframe is the alumina ceramics material, and the compartment of terrain is provided with some wall screw on the last plane of described underframe, and described wall screw penetrates in the through hole of described upper frame lower plane and by nut described upper frame is connected with underframe.
The alumina ceramics material of above-mentioned underframe is a castable, and described wall screw is planted plane on underframe when described underframe is poured into a mould with the alumina ceramics material.
Because the zinc nose in the utility model cold-rolled steel strip zinc bath has adopted technique scheme, promptly adopt the underframe of alumina ceramics material cast zinc nose, and when cast, the some wall screw of plantation are connected with upper frame by wall screw on plane on the underframe; Owing to adopt alumina ceramics material cast zinc nose underframe, make the zinc nose in galvanized bath, can not tie zinc, thereby avoid the distortion of zinc nose, guaranteeing that cold-rolled steel strip is galvanized normally carries out, and has reduced repair rate.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of zinc nose underframe in the utility model cold-rolled steel strip zinc bath,
Fig. 2 is the interior zinc nose of the utility model cold-rolled steel strip zinc bath assembling synoptic diagram of framework up and down.
Embodiment
As shown in Figure 1, zinc nose in the utility model cold-rolled steel strip zinc bath, comprise upper frame 1 and underframe 2, described upper frame 1 is that the stainless steel plate welding is made, lower plane 11 compartment of terrains of described upper frame 1 have some through holes, described underframe 2 is alumina ceramics materials, and the compartment of terrain is provided with some wall screw 3 on the last plane 21 of described underframe 2, and described wall screw 3 penetrates in the through hole of described upper frame 1 lower plane 11 and by nut described upper frame 1 is connected with underframe 2.
The alumina ceramics material of above-mentioned underframe 2 is castables.Described wall screw 3 is planted plane 21 on underframe 2 when described underframe 2 usefulness alumina ceramics materials are poured into a mould.
Zinc nose in this cold-rolled steel strip zinc bath adopts the underframe 2 of alumina ceramics material cast zinc nose, and when cast, the some wall screw 3 of plantation are connected with upper frame 1 by wall screw 3 on plane 21 on the underframe 2; Owing to adopt alumina ceramics material cast zinc nose underframe 2, make the zinc nose in galvanized bath, can not tie zinc, thereby avoid the distortion of zinc nose, guaranteeing that cold-rolled steel strip is galvanized normally carries out, and has reduced repair rate.
