Abstract
The utility model discloses a kind of improved conticasters to arc tool, including pedestal, vertical affixed a L shape support rod on pedestal, vertical affixed the bending bar in the horizontal free end of support rod, the length of bending bar is 200mm, and the height of support rod vertical section is 1000mm, and the length of support rod horizontal segment is 450mm, bending bar lower end it is affixed one piece of arc band steel, the central angle of arc band steel be 90 degree.After to arc tool, 2-3 people is only needed to arc, a stream time is 1-3 hours to the arc time, has not only reduced worker's labor intensity, but also reduce to the arc time.
Description
Technical field
The utility model relates to a kind of improved conticasters to arc tool.
Background technique
After molten steel is cooled into initial solidification shell in crystallizer, into secondary cooling zone, further cooling, solidification.Two is cold
Supporting arrangement is located at the lower section of crystallizer, pulls out the continuous casting billet not solidified completely by crystallizer for supporting, while guiding continuous casting
Arcuately line steadily moves base.
Backing roll is necessarily worn continuous casting billet in the process of running, makes crystallizer, backing roll and withdrawal straightening machine not on camber line,
It is often found that backing roll and dummy bar have a gap when maintenance down, when test, generally there is 1-3mm, reach 5mm individually.This feelings
Condition generates mechanical stress to the slab in process of setting, can cause the deformation of green shell, so as to cause the generation of crackle.
It is conventional overhauling project to arc, it is easy to solve this problem.To arc also known as school arc, mainly using dedicated
Arc template is on the basis of the first roller (throwing lower roll) of crystallizer extrados and withdrawal straightening machine, to examine two cold guided bearing roller institutes
Whether the arc of formation is normal.Standard requirements: gap≤0.3mm between arc template and backing roll is such as more than this standard,
Two cold guided bearing rollers can be adjusted, until arc is normal.It is time-consuming and laborious to arc operation, arc is operated and needs 6 people,
One stream time is 4-6 hours to the arc time, sometimes more than 6 hours.The large percentage of repair time is accounted for arc, if when maintenance
Between be lower than 8 hours, will abandon to arc, such continuous casting billet there is quality risk.
Summary of the invention
The purpose of this utility model is to provide a kind of improved conticasters to arc tool, after to arc tool, to arc
2-3 people is only needed, a stream time is 1-3 hours to the arc time, has not only reduced worker's labor intensity, but also reduce to the arc time.
The purpose of this utility model is achieved in that a kind of improved conticaster to arc tool, including pedestal, on pedestal
Vertical affixed a L shape support rod, the horizontal free end of support rod vertical affixed a bending bar, the length of bending bar are
200mm, the height of support rod vertical section are 1000mm, and the length of support rod horizontal segment is 450mm, bending bar lower end it is affixed one
Block arc band steel, the central angle of arc band steel are 90 degree.
Before use, first with to arc, guaranteeing four backing rolls on a camber line on arc template.Then the utility model is used
To arc tool, the arc band steel to arc tool is placed on backing roll roll surface, (the measurement reference parallel with reference plate of adjustment measurement plate
Version is equidistant with measurement board ends), measurement is 50mm referring to the distance between version and measurement plate, the number based on this data
According to.In use, the arc band steel to arc tool is placed on backing roll roll surface, backing roll can be adjusted upward or downward, until
Until the distance between reference plate and measurement plate reach 50 ± 0.3mm, finally backing roll is fixed.After to arc tool,
2-3 people is only needed to arc, a stream time is 1-3 hours, when not only having reduced worker's labor intensity, but also having reduced to arc to the arc time
Between.
Detailed description of the invention
The utility model is described in further detail below in conjunction with attached drawing.
Fig. 1 is the schematic view of the front view of the utility model；
Fig. 2 is the side structure schematic view of the utility model；
Fig. 3 is the using state structure diagram of the utility model.
Specific embodiment
A kind of improved conticaster is to arc tool, as shown in Figure 1, Figure 2, Figure 3 shows, including pedestal 3, vertical affixed on pedestal 3
A L shape support rod 2, the horizontal free end of support rod 2 vertical affixed a bending bar, the length of bending bar are 200mm,
The height of 2 vertical section of support rod is 1000mm, and the length of 2 horizontal segment of support rod is 450mm, bending bar lower end it is affixed one piece of arc
Shape band steel 1, the central angle of arc band steel 1 are 90 degree.In use, the arc band steel 1 to arc tool is placed on 4 roll surface of backing roll
On, adjustment measurement plate is parallel with reference plate (measurement reference plate is equidistant with measurement board ends), measurement reference plate and measurement
The distance between plate can adjust backing roll, Zhi Daocan if measurement data is less than or greater than 50 ± 0.3mm upward or downward
Until reaching 50 ± 0.3mm according to the distance between version and measurement plate, finally backing roll is fixed.
