Description

[Detailed Description of the Invention] (Related Industrial Field) The present invention relates to an improvement of a continuous cast piece support guide segment directly below the mold in a continuous casting machine.

(Prior Art) In a variable width mold for a continuous casting machine, the thickness is constant and only the width dimension can be changed.
Since the solidified shell of the continuous cast piece (hereinafter referred to as continuous cast piece) pulled out from the mold is thin, it is necessary to support and guide the continuous cast piece for a while after it comes out of the mold. Therefore, the relative positioning of the short side of the mold and the short side support guide member directly under the mold is important. If the short side support guide member directly under the mold is significantly deviated forward of the short side of the mold, that is, in a direction that reduces the width dimension, the solidified shell will break and breakout will occur. On the other hand, if the short side support member is located significantly behind the short side of the mold, the solidified shell swells, bulging occurs, and the quality of the continuously cast piece deteriorates.

In order to solve this problem, conventionally a foot roller 4 was installed at the lower end of the mold 2' as shown in FIG.
4' was installed. That is, rolls that vibrated together with the mold were attached to each of the long and short sides. Platy guide members were sometimes used instead of rolls.

By attaching the foot roller 4 to the short side mold 2a, the relative position between the short side mold 2a and the foot roller 4 does not change regardless of the position of the short side mold 2a, and the solidified shell on the short side side is accurately supported. invite. This also applies to long side molds.

However, when a foot roller is attached to the mold 2', the mold 2' becomes heavier, and as a result, the mold vibrating device becomes larger, which not only increases the equipment cost but also makes it difficult to handle the mold. .

(Problems to be Solved by the Invention) The object of the present invention is to eliminate these conventional problems and provide a continuous slab guide segment that reliably supports and guides the continuous slab.

(Means for Solving the Problems) The gist of the present invention for solving the above problems is to provide a mold with a continuous slab support and guide member attached to the lower end, and a plurality of continuous slabs directly below the mold. In combination with a segment incorporating a support guide member, the continuous casting wall support guide member to be attached to the lower end of the long side mold is installed at the upper end of the long side of the segment, and at the same time, the continuous casting wall support guide member to be attached to the lower end of the long side mold is installed at the upper end of the short side of the segment. , is characterized in that a notch is provided to accommodate a continuous slab support and guide member attached to the lower end of the short-side mold.

(Example) The example shown in the drawings will be described below. In Figures 1 and 2, 1 is a mold piece, 2 is a mold,
Reference numeral 3 denotes a segment directly below the mold, and a plurality of continuous cast piece supporting and guiding members 5 incorporated in the segment 3 support and guide the continuous cast piece 1 that is pulled out from the mold 2 and transferred.

A foot roller 4 is attached to the lower end of the short-side mold 2a as a continuous slab support and guide member. A notch S for accommodating the foot roller 4 is formed in the upper part of the short side of the segment 3, and a pipe (not shown) for supplying cooling water around the foot roller 4 is formed in the notch S. ) is provided.

Furthermore, in the present invention, the continuous slab support and guide member (here, the foot roll 4') provided at the lower end of the long side mold 2b directly below the mold is incorporated into the upper end of the long side of the segment 3, and is not incorporated into the segment 3. The continuous cast strip 1 is supported and guided in cooperation with a plurality of continuous cast strip supporting and guiding members 5 provided therein.

(Operations and Effects) By configuring as described above, the continuous slab 1 has the following features:
The fact that it is pulled out of the mold 2 and suitably supported and guided by the segment 3 directly below the mold is the same as in the conventional method. At this time, the continuous slab support and guide member that should be attached to the long side mold was omitted, and the omitted continuous slab support and guide member was attached to the segment directly below the mold without changing its position, so the weight of the mold was greatly reduced. This makes it possible to reduce the size of the mold vibrating device, thereby making it possible to reliably achieve the intended purpose of the invention.

In addition, in the present invention, a notch S is provided at the upper end of the short side of the continuous cast piece support guide segment directly under the mold to accommodate the continuous cast piece support guide member attached to the lower end of the short side mold. The short side of the rectangular guide segment can be brought close to the short side of the maximum width of the continuous cast slab to be produced, which makes it possible to make the equipment more compact and greatly reduce equipment costs. , the amount of deformation of the guide segment due to the internal pressure of the slab via the slab long side guide member (foot roll 4') is also reduced, which is expected to have a great industrial effect as it can greatly contribute to the production of high quality slabs. .
