Abstract
The utility model relates to a relative component of a rolling mill for medium plate heat rolling in metallurgy industry, in particular to a breakwater water sealing device of the rolling mill for medium plate heat rolling. The utility model comprises a breakwater and an upper working roll guiding plate; wherein, a hollow rubber bursa is arranged on the breakwater. One end of the hollow rubber bursa is connected with a working roll cooling water tube through a joint, and the other end is blocked up using a blanking adapter through a joint. A working face contacts with the upper working roll guiding plate. When the working roll is changed, the working roll cooling water is closed, and the hollow rubber bursa separates from the upper working roll guiding plate. The working roll is pushed in and pulled out of the rolling mill without damaging the hollow rubber bursa, and hollow rubber bursa can not be damaged when the breakwater is adjusted up and down, thereby reducing the consumption of spare parts and reducing machine halt times. When steel rolling is carried out, the working roll cooling water is opened, and the hollow rubber bursa is tightly jointed with the upper working roll guiding plate, thereby guiding a great deal of cooking water to the two sides to flow out, avoiding the cooling water to fall on the rolling workpieces and reaching ideal water sealing effect.
Description
Technical field
The utility model relates to the associated components of the cut deal hot rolling mill in the metallurgy industry, specifically cut deal hot rolling mill water fender sealing water device.
Background technology
Generally all sealing water device will be installed between the water fender of cut deal hot rolling mill and the top working roll foreplate, purpose is for a large amount of cooling water guiding top working roll foreplates both sides being flowed out, avoiding cooling water to drop on the rolled piece.Existing cut deal hot rolling mill water fender sealing water device structure as shown in Figure 1, it is pressed in rubber bar 3 on the water fender 1 by bolt 4, rubber bar 3 is closely contacted with top working roll foreplate 2, from reaching the purpose of cooling water guiding top working roll foreplate 2 both sides that make on the milling train, do not make cooling water drop to the rolled piece table.There is following shortcoming in existing this cut deal hot rolling mill water fender sealing water device: 1. working roll will often be changed, when changing jobs roller at every turn, new and old working roll will advance and pull out milling train repeatedly, water fender also will be adjusted height up and down to adapt to roll change and steel rolling condition, these work all make between rubber bar and the top working roll foreplate and produce relative motion, thereby the wearing and tearing of aggravation rubber bar, not only rolled up spare parts consumption, increased the shutdown number of times, and water sealing effect is had a greatly reduced quality; 2. owing to will produce relative motion between rubber bar and the top working roll foreplate, and there is not the effect of additional force between them, make water sealing effect not reach desirable requirement, cause a large amount of cooling waters to drop on the rolled piece, make the rolled piece temperature drop too fast, seriously influenced steel rolling, especially the steel grade of influence of rolled high standard kind.This shows that existing cut deal hot rolling mill water fender sealing water device haves much room for improvement.
Summary of the invention
The purpose of this utility model is to propose a kind of consumption that reduces spare part, the better cut deal hot rolling mill of water sealing effect water fender sealing water device.
The purpose of this utility model can be achieved through the following technical solutions:
Cut deal hot rolling mill water fender sealing water device, comprise water fender, top working roll foreplate, it is characterized in that: it is former to be provided with the hollow rubber on water fender, the former end of described hollow rubber links to each other with the working roll cooling water pipe by joint, the other end is provided with plug, and the former working face of hollow rubber closely contacts with the top working roll foreplate.
The purpose of this utility model can also come further to realize by the following technical programs:
Aforesaid cut deal hot rolling mill water fender sealing water device, wherein said hollow rubber is former fixedlys connected with water fender by mounting bracket, pressing plate, securing member, mounting bracket is fixed on the water fender by trip bolt, and the hollow rubber is former to be fixed on the mounting bracket by pressing plate.
Aforesaid cut deal hot rolling mill water fender sealing water device, wherein said hollow rubber is former to be that Ω type hollow rubber is former.
Advantage of the present utility model is: the former end of hollow rubber links to each other with the working roll cooling water pipe by joint; the other end blocks with plug by joint; working face contacts with the top working roll foreplate; when changing jobs roller; the working roll cooling water is closed; the no pressure in the former inside of hollow rubber; the hollow rubber is former to be separated with the top working roll foreplate; working roll can advance and pull out milling train and not damage the hollow rubber former; it is former that same water fender can not damage the hollow rubber when adjusting up and down yet; can reduce the consumption of spare part, reduce and shut down number of times.When steel rolling, the working roll cooling water is opened, there is hydraulic pressure the former inside of hollow rubber, former this hydraulic pressure that utilizes of hollow rubber closely sticks together with the top working roll foreplate, thereby making a large amount of cooling waters be directed to both sides flows out, avoided cooling water to drop to possibility on the rolled piece, made water sealing effect reach desirable effect.
Description of drawings
Fig. 1 is the structural representation of existing cut deal hot rolling mill water fender sealing water device.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Embodiment one
The structure of present embodiment as shown in Figure 2, a kind of cut deal hot rolling mill water fender sealing water device, comprise water fender 1, top working roll foreplate 2, on water fender 1, be provided with hollow rubber former 7, hollow rubber former 7 is that Ω type hollow rubber is former, the one end links to each other with the working roll cooling water pipe by joint, and the other end blocks with plug by joint, and working face contacts with top working roll foreplate 2.Hollow rubber former 7 is fixedlyed connected with water fender 1 with 8 by mounting bracket 5, pressing plate 6, securing member 4.The concrete mounting means of hollow rubber former 7 is: row's trip bolt 8 is fixed on mounting bracket 5 above the water fender 1, and two row's fastening bolts and nut 4 are fixed on hollow rubber former 7 on the mounting bracket 5 by pressing plate 6.
The utility model in the specific implementation, because former 7 one ends of hollow rubber link to each other with the working roll cooling water pipe by joint, the other end blocks with plug by joint, working face contacts with top working roll foreplate 2, when steel rolling, the working roll cooling water is opened, there is hydraulic pressure former 7 inside of hollow rubber, hollow rubber former 7 utilizes this hydraulic pressure closely to stick together with top working roll foreplate 2, thereby flow out the both sides that make a large amount of cooling waters be directed to top working roll foreplate 2, avoid cooling water to drop on the rolled piece, played sealing function.When changing jobs roller, the working roll cooling water is closed, hollow rubber former 7 inner no pressure, hollow rubber former 7 separates with top working roll foreplate 2, working roll can advance and pull out milling train and do not damage hollow rubber former 7, same water fender 1 can not damage the hollow rubber yet when adjusting up and down former 7, and the roller that changes jobs is more convenient.
The utility model can also have other embodiment, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
