Description

Technical Field

[0001] The invention relates to the technical field of continuous casting equipment, in particular to a sector segment of a profiled blank continuous casting machine. Background Art

[0002] In the continuous casting machine of the metallurgical industry, there are usually several fan-shaped segments in the secondary cooling chamber for supporting the ingot coming out of the crystallizer, and a straightening machine is arranged below the fan-shaped segments.

[0003] The shell of the billet just out of the copper tube of the crystallizer is very thin and the temperature is very high, so it is easy to bulge and deform; especially for the special-shaped billet or rectangular billet with a large cross-section, the solidification process of the core of the billet is relatively long, and many rows of rollers are required to support the billet, and each row of rollers supports the billet on each surface of the billet. When the special-shaped billet first comes out of the crystallizer, there are 8 rollers in each row to support the 8 surfaces of the billet. In addition, the gap between the upper and lower rows of rollers is required to be very small to better prevent the billet from bulging; in addition, nozzles of the spray system will be arranged between the rollers. This causes a common problem of multi-faceted closely spaced roller fan-shaped segments, that is, the rollers in the middle part cannot be approached; because they are far away from the openings at both ends of the fan-shaped segment, they cannot be approached from both ends; the gap between the rollers is small, and nozzles or various system pipelines may be arranged, and tools or workers' arms cannot approach the internal rollers from the gap between the rollers. This problem makes it very difficult to adjust the centering, maintenance, disassembly and replacement of the rollers in the middle part of the fan-shaped segment. Summary of the invention

[0004] In order to facilitate maintenance, the present invention provides a fan-shaped segment of a special-shaped blank continuous casting machine, in which each roller unit is detachably connected to an outer arc frame. If the fan-shaped segment of the special-shaped blank continuous casting machine is locally damaged due to some reasons (such as steel leakage), only the damaged roller unit needs to be replaced, and the maintenance operation is convenient.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a sector of a profiled blank continuous casting machine, comprising an outer arc frame and a plurality of roller units, the plurality of roller units are arranged at intervals along the billet discharging direction, and each roller unit is detachably connected to the outer arc frame.

[0006] The outer arc frame is provided with a plurality of installation grooves for installing the roller unit. The roller unit comprises a rectangular outer frame. The lower ends of the rectangular outer frame are matched and plugged with the installation grooves in a one-to-one correspondence.

[0007] The outer arc frame includes a front side vertical plate, a bottom plate and a rear side vertical plate which are fixedly connected in sequence from front to back. The mounting groove is located at the upper rear side of the front side vertical plate and the upper front side of the rear side vertical plate. The mounting groove can limit the five degrees of freedom of the roller unit.

[0008] The installation groove on the rear side of the upper end of the front side vertical plate is a front installation groove, and the front installation groove contains a front side installation front reference surface and a front side installation lower reference surface which are vertically connected front and back.

[0009] The front part of the lower end of the rectangular outer frame matches and is inserted into the front installation groove, the front side surface of the lower end of the rectangular outer frame corresponds to and fits with the front side installation front reference surface, and the front part of the lower side surface of the rectangular outer frame corresponds to and fits with the front side installation lower reference surface.

[0010] The mounting groove on the front side of the upper end of the rear side vertical plate is a rear mounting groove, and the rear mounting groove and the front mounting groove corresponding to the front and rear sides are mirror images of each other.

[0011] The lower end of the rectangular outer frame abuts against the bottom plate, and the rectangular outer frame and the bottom plate are connected and fixed by a first bolt.

[0012] The roller unit comprises a rectangular outer frame, an outer arc side roller assembly, an inner arc side roller assembly and a side roller assembly, and the outer arc side roller assembly, the inner arc side roller assembly and the side roller assembly are all located in the rectangular outer frame.

[0013] The outer arc side roller assembly, the inner arc side roller assembly and the side roller assembly are all connected and fixed to the rectangular outer frame by second bolts, and adjustment gaskets are provided between the outer arc side roller assembly, the inner arc side roller assembly and the side roller assembly and the rectangular outer frame.

[0014] The roller unit comprises a rectangular outer frame, the rectangular outer frame comprises a cooling water channel, and the cooling water channel has a rectangular structure.

[0015] The beneficial effects of the present invention are as follows: all rollers of the sector segment are decomposed into several roller units, each roller unit can be disassembled and assembled separately, and a single roller unit can very conveniently adjust the precise distance between the roller surface and the reference surface, and when the roller unit is installed on the outer arc frame, there is an installation groove for precise positioning, thereby ensuring the precise positioning of the roller, and no repeated arc adjustment is required. The above-mentioned problem that the rollers in the middle part of the sector segment cannot be accessed is solved, and maintenance, disassembly, assembly and replacement can be conveniently performed, and centering adjustment is also very convenient.
