Description
Technical field
Hot-strip is the utility model is related to, particularly a kind of Coil Box for preventing coil of strip sideslip.
Background technology
In hot-continuous-rolling strip steel factory, because production technology needs, equipped with Coil Box equipment, after Coil Box is coiled, open
Deviation phenomenon be present during volume transfer, cotter pin deformation is scrapped or departs from roller-way Mobile steel on flying shear front-side is led when serious
Volume scratches, while steel scrap failure occurs, and causes production to be carried out continuously, coil of strip surface has quality problems.
The content of the invention
Technical problem to be solved in the utility model is：Coil Box how is set steadily to be moved during being transferred after uncoiling
Send, the occurrence of preventing or control coil of strip sideslip, ensure Coil Box equipment stable operation.
Technical scheme is used by the utility model：A kind of Coil Box for preventing coil of strip sideslip, including frame, the first mistake
Roller, the second transition roller, registration roller, top pinch roll, bottom pinch roll are crossed, bottom pinch roll transmission side roll surface central point is than fore side roll surface
Central point high 0.3-0.5mm in vertical direction.
As a kind of preferred embodiment：The roller on the basis of First Transition roller, the second transition roller, registration roller, top pinch roll, lower folder
The deviation of roller and reference roller is sent to be less than 2mm, i.e. the second transition roller, registration roller, top pinch roll, the two-end-point of bottom pinch roll center line
Difference to the distance of reference roller is respectively smaller than 2mm, such as：One end of the center line of second transition roller to First Transition roller away from
From for L1, the distance of the other end to the First Transition roller of the center line of the second transition roller is L2, then | L1-L2 |≤2mm.
As a kind of preferred embodiment：During the bearing block installation of bottom pinch roll, the bearing block of bottom pinch roll is with frame entrance side
Bearing block plane be datum clamp face, datum clamp face and the parallel misalignment of bearing block plane are less than 0.1mm/m（This is flat
Row degree deviation is every meter of length variation 0.1mm, as two bearing block centre-to-centre spacing of roller be 2.5 meters, i.e. deviation is less than 0.25mm）.
Frame entrance side has two faces, is transmission side and fore side；The datum clamp face exactly bearing block when installing bearing connects with frame
Tactile plane.
The beneficial effects of the utility model are：Sideslip problem is controlled during the utility model can make steel-coil transferring
System, ensure that production is carried out in order, create huge economic benefit in production.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is bottom pinch roll structural representation；
Fig. 3 is bottom pinch roll installation sketch.
Wherein, 1, First Transition roller, 2, registration roller, the 3, second transition roller, 4, top pinch roll, 5, bottom pinch roll, 6, lower folder
Send roller datum clamp face, 7, transmission side roll surface, 8, fore side roll surface.
Embodiment
As shown in figure 1, the utility model is the improvement to existing equipment, Coil Box can be controlled to be transferred after uncoiling
Coil of strip deviation phenomenon in journey, ensure that production is carried out in order, create huge economic benefit in production.
Bottom pinch roll installation horizontal level is specified, transmission side is all inclined to reference to each sideslip, makes transmission side roll surface absolute altitude ratio
Fore side roll surface absolute altitude wants high 0.3-0.5mm.
Using the bearing block plane of frame entrance side as datum clamp face when pinching roll bearing seat installation（Frame entrance side is two
Individual face, divides transmission side and fore side；Datum clamp face is exactly the plane contacted in mounted roller period of the day from 11 p.m. to 1 a.m roller axle bearing with frame）,
Deviation is less than 0.1mm/m simultaneously（This deviation is every meter of length variation 0.1mm, if two bearing block centre-to-centre spacing of roller are 2.5
Rice, i.e., deviation is less than 0.25mm）.
Each roller system locus standard is specified, the roller on the basis of First Transition roller, detects each roller system relative position.Each roller system
Deviation be less than 2mm.
Top pinch roll pressure criteria is formulated, pressure value is determined according to the thickness and width for batching middle base.Base is wide among i.e.
Degree is set as 140 ~ 150KN more than 1400mm, thickness more than 30mm pressure above values.Middle base width is less than 1400mm, thickness
Design of pressure less than 30mm is 100 ~ 120KN.Special requirement is as rolled Thin Specs T700 beams, workpiece thickness 26,28mm
Design of pressure be 90KN.
Formulation selection principle is selected to the sensor of pinch roll hydraulic cylinder, preferentially newly changes cylinder sensor from numerical value；
Secondly sensor both sides numerical value change, the small sensor of the changing value that comes into operation are paid close attention in use.
Before Shanxi Taigang Stainless Steel Co., Ltd's hot continuous rolling does not use the utility model, every year because sideslip causes
12 hours about 15 years fault time, damage 2 sets of cotter pin parts, 16 year 9.48 hours fault time of steel scrap 12 piece, steel scrap 10
Block.Using after this practicality, sideslip problem is controlled during steel-coil transferring.Existing running deviation value is substantially within 100mm, during failure
Between drop to 1 hour.* 700 tons * 300 yuan=1,890,000 yuan of annual benefit 9 hour（Our factory produces 600 tons of coil of strip, ton steel per hour
300 yuan of process benefit）, reduce 10 pieces * 30 tons * 5000 yuan=1,500,000 yuan of steel scrap benefit.It is total 3,390,000 yuan.
