Description
Technical field
The utility model belongs to steel-making continuous casting equipment technical field more particularly to a kind of special-shaped billet continuous casting machine fan-shaped section edge of a wing
Support roller correcting tool.
Background technique
For special-shaped billet continuous casting machine crystallizer by molten steel solidification at the green shell of Hot Metal in Beam Blank section configuration, center portion is the base of liquid molten steel
Shell enters fan-shaped section, and due to the effect of ferrostatic pressure, green shell easily generates bulge deformation, it is necessary to have support roller to carry out green shell
Support.Since Hot Metal in Beam Blank section configuration is irregular, 8 supporting surfaces are arranged at fan-shaped section top, and as green shell thickens, intensity increases, branch
Support face is gradually reduced to 4 faces, until without support.Support roller is mounted in roller frame, and roller frame is mounted in fan-shaped section.
Due to Hot Metal in Beam Blank section configuration feature, supporting surface is more, and internal and external cambered surface support and lateral support, fan-shaped section top is divided to have
8 supporting surfaces, 6 internal and external cambered surfaces, 2 sides, internal and external cambered surface have two pairs of edge of a wing rollers and 1 pair of web roller support (see Fig. 3).
The section configuration (being commonly called as opening degree) of fan-shaped section support roller composition must be consistent with the green shell that crystallizer is formed, in order to avoid
Green shell generates bulge or is squeezed power, and green shell is thermally stressed and mechanical stress, continuous casting billet generate mass defect.Therefore, right
Fan-shaped section support roller position has installation accuracy that (≤± 0.1mm) is required must to be expired on cross section by the molecular opening degree of roller
Sufficient required precision, in the longitudinal direction, it is desirable that roller must satisfy radian and accuracy of alignment requirement.Hot Metal in Beam Blank features of shape is adjusting
When fan-shaped section roller opening degree, it is necessary to which the relative spacing for first adjusting edge of a wing roller to web roller roll surface reaches required precision, then again
Outer arc roller relative spacing and side roller relative spacing meet required precision in adjusting.
In the process of implementing the utility model, the inventor finds that the existing technology has at least the following problems: the adjustment edge of a wing
Can not directly be measured when roller and web roller roll surface relative spacing with vernier depth gauge, generally with square lean against edge of a wing roller frame into
Row measurement, precision cannot be met the requirements, and be difficult to ensure that edge of a wing roller is parallel to each other with web roller.Current existing measurement method
It is difficult to ensure edge of a wing roller and web roller spacing accuracy, deviation is larger, and the band wick-containing green shell edge of a wing position after leading to crystallizer out is lost
It goes to support or be squeezed, edge of a wing green shell will receive mechanical stress effect and just can not once stress is more than the elevated temperature strength of green shell
Cause the position continuous casting billet to generate serious internal soundness defect with avoiding, such as underbead crack, edge of a wing bulge and depressed deformation etc.,
Bleed-out accident even occurs.
Utility model content
The technical problem to be solved by the utility model is to provide one kind in adjustment Hot Metal in Beam Blank fan-shaped section edge of a wing roller and web
It can directly be measured when roller relative spacing, to guarantee the special-shaped billet continuous casting machine fan-shaped section edge of a wing support roller correction of spacing dimension precision
Tooling.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the utility model is a kind of special-shaped billet continuous casting machine is fanned
Shape section edge of a wing support roller correcting tool, comprising:
Cross bar is horizontally disposed with, and the cross bar is mounted in web roller roller frame；
Locating rod, on the cross bar, vertically the cross bar, cross bar both ends correspond to edge of a wing roller position to the locating rod for setting
Locating rod there are two each, locating rod correspond to edge of a wing roller roller frame, and the length of locating rod is than between edge of a wing roller roller frame and web roller roller frame
The theoretical small 0.5mm of spacing.
It further include pressing plate, the cross bar is mounted in the web roller roller frame by compression bar.
Clearance gauge is equipped between the positioning boom end and edge of a wing roller roller frame.
A technical solution in above-mentioned technical proposal has the following advantages that or beneficial effect, in adjustment Hot Metal in Beam Blank fan-shaped section
It can directly be measured when edge of a wing roller and web roller relative spacing, to guarantee spacing dimension precision.

Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type embodiment is described in further detail.
Referring to Fig. 1-3, a kind of special-shaped billet continuous casting machine fan-shaped section edge of a wing support roller correcting tool, comprising:
Cross bar is horizontally disposed with, and cross bar is mounted in web roller roller frame；
Locating rod is arranged on cross bar, locating rod vertical cross-bar, and cross bar both ends correspond to edge of a wing roller position, and respectively there are two positioning
