Abstract

The utility model provides a device for pressing a bending-upwards end in a hot continuous rolling machine for strip-steel, which is mainly composed of a straightening plate, supporting plates welded on both the left and the right sides of the straightening plate, and bottom plates welded on the bottoms of the supporting plates. The utility model is characterized in that an included angle between the straightening plate and a horizontal plane reverse to rolling direction ranges from 35 DEG to 50 DEG, and the tail section of the straightening plate is provided with a guiding roller which is installed by being perpendicular to the rolling direction, and a cooling water pipe used for cooling the guiding roller. The utility model has the advantages of simple structure, low cost and less space occupation of a machine body. The utility model can flatten a bending-upwards end generated in rolling strip-steel in time.

Description

Tandem hot strip mill is pressed the nose device

The utility model relates to a kind of metal rolled secondary process device, particularly relates to the secondary process device in a kind of hot strip rolling process.

The band steel is in the rolling process of Continuous Heat, when producing difference, will cause being with steel to produce ＂ nose ＂, as if untimely processing when heating-up temperature inequality about the slab and with rolling mill upper working rolls and lower working rolls linear velocity, then directly influence band steel enters next rolling mill smoothly and produces waste product, even causes production accident.At present, China large-scale a bit band steel factory still takes to hang the big stone roller of ＂＂ on hoist lifting hook, and ＂ flattens ＂ nose ＂ with the big stone roller of ＂.Handle ＂ nose ＂ with this way, when not only taking too much crane operation platform, the more important thing is influence of rolled rhythm, in addition, because of pressing ＂ nose ＂ spended time long like this, make band steel temperature drop cross the inherent quality that conference influences the band steel to a certain extent, and can cause mill load to increase, influence the safe operation of milling train.Some band steel factory in economic technology developed country, as some hot strip rolling producer of Belgium and Germany, they are supporting mostly to be equipped with suspension type and heavily to cut or polish jade with an emery wheel and press the nose device.This device high efficiency, but body is huge, cost is high.

The purpose of this utility model provides a kind of tandem hot strip mill simple in structure, that body takes up space little, that cost is low and presses the nose device.

For achieving the above object, designer of the present utility model provides a kind of duck-beak type tandem hot strip mill to press the nose device, the base plate that this device mainly comprises straightening plate, is fixedly welded on the gripper shoe of the straightening plate left and right sides and is welded on the gripper shoe bottom, it is characterized in that, angle is the 35--50 degree between the reverse horizontal plane of straightening plate and rolling direction, also is provided with one with the vertically arranged guide reel of rolling direction be used for cooling off the cooling water pipe of this guide reel at the straightening plate afterbody.

Pressure nose device as previously discussed is characterized in that, straightening plate is with longitudinal guide plate and the horizontal supporting plate integral body that is welded.

Because the available common iron of pressure nose device described in the utility model process, weld, assemble and also can be fixed as required on the roller-way sole plate that is installed to appropriate position on the roll line, when the band steel that produces nose after being introduced into this device under the roller-way transmission, under the clamping action of the ＂ duckbill ＂＂ a ＂ angle that forms between straightening plate and roller-way horizontal plane, ＂ nose ＂ just can be driven plain automatically, therefore, press the nose device to compare with existing band steel, that this device has is simple in structure, cost is low, easy to assemble, advantage such as little takes up space.

The utility model is described in further detail below in conjunction with drawings and Examples

Fig. 1 is the front view of the utility model embodiment 1.

Fig. 2 is the front view of the utility model embodiment 2.

Fig. 3 is the left view of Fig. 2.

Fig. 4 is the vertical view of Fig. 2.

In embodiment shown in Figure 11, its straightening plate 1 is with a monoblock or is soldered to polylith splicing all-in-one-piece steel plate on the gripper shoe 2 of its left and right sides.

In embodiment shown in Figure 22, its straightening plate then be by the longitudinal guide plate made from steel plate and laterally supporting plate again it is welded to after in aggregates with form welding assembly shown in Figure 4 on the gripper shoe 2 of its left and right sides.

As Fig. 1, Fig. 2, shown in Figure 3, no matter the monoblock steel plate type straightening plate 1 among the embodiment 1 still is by longitudinal guide plate 3 and horizontal supporting plate 7 welding assemblies grid type straightening plate 1 in aggregates among the embodiment 2, all be to make it on the symmetric position of its left and right sides gripper shoe 2 and guarantee that angle a is welded on the gripper shoe 2 for the 35--50 degree between itself and roller-way horizontal plane, gripper shoe 2 then is vertically to be soldered on the base plate 3.Base plate 3 is to be fixedly installed on the roller-way soleplate of desired location on the roll line with stud 9 and nut.Guide reel 5 connects with gripper shoe 2 by bearing block loam cake 14, bearing block 11, bearing block carriage 12 and is installed together, and the bearing block loam cake 14 and the bearing block 11 of guide reel 5 are to be installed on the bearing block carriage 12 that is welded on the gripper shoe 2 with stud 13 and corresponding nut.

For increasing the intensity of gripper shoe 2, respectively be welded with three triangle gussets 4 in gripper shoe 2 and about 3 of base plates.

After band steel described in the utility model pressed the nose device that guide reel 5 is set, belt steel surface was scratched in the time of can avoiding being with the steel nose to be driven plain, also help being with simultaneously steel from this device smoothly by and be introduced into down rolling mill and proceed rolling.

Because guide reel 5 will stand the baking of high temperate zone steel for a long time, designer of the present utility model has set up the cooling water pipe 6 with the 5 parallel installations of this guide reel in guide reel 5 front upper places, this cooling water pipe 6 is to be fixedly connected with the steel pipe securing member that is welded on the gripper shoe 2.

For ease of installing and this pressure nose device can being pulled down from roll line where necessary and be hung away, on left and right sides gripper shoe 2, also be welded with suspension ring 10 symmetrically.

The foregoing description has all adopted the A3 steel plate to make model machine, and is satisfactory for result and sturdy and durable through confirmation on probation.
