を連続的に鋳造する方法が提案されている。(Prior art) As a method of manufacturing hollow tubular slabs by horizontal continuous casting, a gap is formed between the outer mold and the rear of the tundish bottom to determine the thickness of the slab, which is connected to the outer mold horizontally at the bottom of the tundish. An inner mold cantilevered by the tundish is provided, and molten steel from inside the tundish is supplied between both molds and cooled from the inside and outside by both molds to form a solidified shell and then drawn into a hollow tubular shape. A method of continuously casting slabs has been proposed.

In addition, this mold is cantilevered at the bottom of the tundish, and is inserted into the outer mold from the molten steel at the bottom of the tundish.
The supporting structure of the mold is also complicated, and defects in this supporting structure can lead to accidents such as leakage of molten steel.

としても、鋳片厚は一定とするものである。 In addition, in the horizontal continuous casting method, the outer shape of the slab is solidified and shaped into a circular or rectangular shape using a conventionally known mold, but at the same time, a core mold is inserted inside the slab and solidified around the mold. A method and apparatus have also been proposed for developing layers and ultimately casting a long hollow slab having holes in the longitudinal direction by bonding the inner and outer solidified layers. (Unexamined Japanese Patent Publication No. 1983-
(Refer to Publication No. 1053) Furthermore, when casting a hollow slab in the core type as described above, a rotating electromagnetic stirrer is installed in the mold or near the mold, and the molten steel in the slab is stirred around the axial direction of the slab. A method for casting hollow slabs has also been proposed in which a rotational flow is applied to uniformize the solidification of molten steel in the circumferential direction of the shell and to form a strong shell at an early stage. (Refer to Japanese Unexamined Patent Publication No. 177858/1983) (Problems to be Solved by the Invention) In the conventional core-type hollow slab casting described above, the gap between the mold and the core mold from the tundesh side is Since a method is adopted in which the molten steel is allowed to flow out and solidify as it is, even if the solidification of the molten steel is made uniform by the stirring action on the molten steel by an electromagnetic stirring device from the mold side, the thickness of the slab is It is assumed to be constant.

こともない。(Effects of the Invention) However, in the horizontal continuous casting method of the present invention, in order to cast a hollow tubular slab, rotational centrifugal force is applied to the molten steel inside the solidified shell in the mold by electromagnetic force from an electromagnetic coil. Since the molten steel is allowed to solidify while being fed, there is no need for an inner mold to cool the molten steel from the inside in addition to a mold that cools it from the outside, and there is therefore no risk of water leakage from this inner mold, which could lead to an explosion. Moreover, the structure from the tundish to the mold can be simplified, and accidents such as leakage of molten steel will not occur.

This means that slabs with the same outer diameter and different wall thickness can be obtained using the same mold, and the supply gas also contains an inert gas, such as argon.
By using an inert gas such as nitrogen, the inside of the slab will not oxidize and scale will occur during heating or cooling before rolling, and rolling defects will be less likely to occur. .
