あった。[Prior Art] Current rolled materials, such as steel plates and hot strips, are produced by supplying molten metal from a tundish r into a mold a that releases the slab to be cast, as shown in Fig. 7. to cast an unsolidified slab, and draw it out with a feed roll p.
This is solidified while being cooled by cooling water spray C to continuously cast a long slab d, and this slab d is further divided and rolled into a predetermined shape with a small cross-sectional area using a rolling mill. . In addition, b is a presser roll. Then,
This process for producing rolled material requires a long process and large equipment to produce rolled material with a small cross-sectional area from a large cross-section of a slab, requiring enormous construction costs, maintenance costs, labor, and shaping energy. Incidentally, FIG. 8 is an explanatory diagram of a vertical mold type casting machine, which has the same problem as the horizontal type shown in FIG.

A type casting machine was devised.

、しわ等として現われる。[Problems to be Solved by the Invention] The mold type casting machine (Fig. 7.8) has a limited casting speed and cannot perform high-speed casting. Therefore, a long rolling process is required to cast a slab with a large cross-sectional area and produce strips, plates, etc. with a small cross-sectional area. If the gap is made smaller, the strip can be directly cast, but because the plate is thin, the molten metal that is rapidly cooled on the circumferential surface of the cooling rolls e and e will solidify unevenly, resulting in cracks, scratches, and wrinkles, which will affect the quality of the strip. harm the In other words, solidified shells with different temperatures are generated at the peripheral surface of the casting machine's roll, the side dam, etc., so when casting slabs that have a small cross-sectional area and are close to completely solidified, it is necessary to Collect the lumps and
It will be shaped using a roll gap. However, each solidified mass has a different crystal structure depending on the temperature, and when collected, discontinuous boundaries occur, which appear in the molded material as cracks, flaws, wrinkles, etc.

従って、これら鋳造機は末だ実用化されていないのが実

A continuous caster is equipped with a slab crushing device that crushes unsolidified slabs cast by a continuous casting machine while conveying them using a continuous endless circulating body, and pushes out the middle of the unsolidified slabs to reduce the cross-sectional area. This is a casting device.

題点は解消される。(3) After the unsolidified slab is cast by the continuous casting machine, the slab is crushed using the slab crushing device, so the continuous endless circulating body of the slab crushing device does not come into direct contact with the molten metal. Therefore, the continuous endless circulating body can have a relatively long life, and the slab can have a smooth surface, so the problems of the conventional method are solved.

A first cooling water spray device 6 for cooling the unsolidified slab 5^ is connected in a loop shape to crush the unsolidified slab 5^ after passing through the first cooling water spray device 4, and moves in endless circulation. This is a caterpillar type crushing device. The caterpillar type crushing device 6 has upper and lower caterpillars arranged at an angle, and the interval between the outlet and the inlet is set smaller. Each caterpillar piece is also internally water cooled to cool the slab. 10 is a pinch roll installed downstream of the caterpillar type crushing device 6, 11 is a cooling water spray device placed downstream of the pinch roll, and 12 is a fully solidified slab 5B sent through the cooling water spray device 11. The crop shear that cuts the front and rear ends, 13.14.15 sequentially rolls the completely solidified slab 5B and hot strips 5C.
These are the first, second, and third rolling mills that form the .

片５Ｂの先端をクロップシャー１２で切断する。The operation begins by plugging the roll gap of the casting roll 1a, allowing metal to adhere to the plug, and feeding the unsolidified slab together with the plug through a dummy bar through the caterpillar crushing device 0, using pinch rolls, and cooling water spray device 11. The dummy bar is removed from the slab when it exits the slab, and the tip of the slab 5B is cut off with the crop shear 12 as described above.

となる。In the above, in order to prevent a discontinuous crystal structure from forming in the solidified part of the slab, the slab 5B is completely solidified by the casting roll la.
An unsolidified slab 5A is cast with a cross-sectional area larger than that, and the solidified slab 5A is crushed by a caterpillar crushing device 6 while extruding medium molten metal to reduce the cross-sectional area of the slab 5A. Transfer while increasing the That is, when the slab 5A is crushed by the caterpillar type crushing device 6, the length of the outer periphery of the cross section where the solidified shell is formed is constant, and the unsolidified molten metal inside is extruded from the cross section, and the length is larger than the solidified shell. Since it is fed at a slow speed, the cross-sectional area is reduced and solidification is accelerated. Therefore, the relationship between the pouring speed Ve and the transport speed v1 of the slab 5^ of the casting roll la section and the caterpillar section of the caterpillar crushing device 6 is v6<vl.

<V4, and the relationship between the transfer speed of the entire line is V6 < v
l<V2<V3<V4.
従って、斯かる速度条件によって連続操業が可能となる
。Therefore, such speed conditions allow continuous operation.

In the belt-type crushing device 7, a loop-shaped belt arranged vertically at an angle is moved endlessly by a drive pulley 7a to crush the unsolidified slab 5A. On the back side of the belt, there are a support roll 7b and a cooling water spray device 7c, which indirectly cool the unsolidified slab 5^.
