Problems solved by technology
With the development of metallurgical technology in the world, modern continuous casting technology continues to improve, and the shape of continuous casting slabs, especially the shape of corners, is becoming more and more complex. For complex corner shapes, the existing drawing forming and cold bending forming processes Unable to meet the precision requirements of diversion water jacket
For this reason, it is necessary to use mechanical processing to meet the precision requirements of the diversion water jacket, which greatly increases the processing and manufacturing costs

Embodiment Construction
[0036] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0037] Such as figure 1 As shown, the composite diversion jacket for the tubular crystallizer with chamfers includes a left half diversion jacket 1 , a right half diversion jacket 2 and an inlay 3 .
[0038] The four corners 5 on the left half diversion water jacket 1 and the right half diversion water jacket 2 are circular arc angles naturally formed by bending the steel plate. The inlay 3 is arranged at the corner of the inner surface of the composite diversion water jacket. The shape of the inner surface is the same as the shape of the outer surface of the corner of the crystallizer copper tube 6. After welding the left half of the diversion water jacket 1 and the right half of the diversion water jacket 2 together, a water seam 7 with a uniform thickness S is formed on the outer surface of the mold c...

Abstract
The invention relates to the field of metal solidification and continuous casting, in particular to a flow guide water jacket for a tubular crystallizer with a composite chamfer and a preparation method of the flow guide water jacket. The composite flow guide water jacket is arranged on the periphery of a copper tube (6) of the crystallizer with the chamfer. The composite flow guide water jacket comprises a flow guide water jacket shell, embedding bodies (3) and a water joint (7). The flow guide water jacket shell is formed by welding a steel plate, and is provided with four right angles or four arc angles naturally formed by bending the steel plate. The embedding bodies (3) are arranged on the inner surfaces of corners (5) of the flow guide water jacket shell, and the shape of the inner surfaces of the embedding bodies (3) is the same as the shape of the outer surfaces of the chamfered portions of the copper tube (6) of the crystallizer. The adjustable water joint (7) even and consistent in thickness is formed between the flow guide water jacket shell and the copper tube (6) of the crystallizer. The flow guide water jacket is easy to prepare, low in cost, and suitable for manufacturing continuous castings in various complex corner shapes.
Description
technical field [0001] The invention relates to the fields of metal solidification and continuous casting, in particular to a diversion water jacket for a tubular crystallizer with composite chamfers and a preparation method thereof. Background technique [0002] Mold is the core of modern continuous casting technology, and the cooling design of mold is the key of this technology. As a form of crystallizer technology, tubular crystallizer is widely used in the production of billets, rectangular billets, round billets, etc. Different from the copper plate form of the combined crystallizer, the copper tube of the tubular crystallizer is a whole. In order to strengthen and uniform the cooling of the crystallizer, it requires the crystallizer cooling water jacket to maintain a uniform water gap with the outer wall of the tubular crystallizer, and the reasonable width of the water gap is generally 3.5-6mm. In the production of traditional square billets, rectangular billets, ro...
