る。(Prior Art) There are various types of twin-belt continuous casting machines, and a typical twin-belt continuous casting machine is shown in FIG. In the twin-belt continuous casting machine shown in the figure, endless steel belts 3 and 4 rotate while being supported by belt support rollers 6 and 7, and an upper steel belt 3 and a lower steel belt 4 rotate. A mold is constituted by a pair of left and right endless side blocks 5 which are driven by being sandwiched between the side edges of the mold and the steel belts 3 and 4. Molten steel 1 produced in a converter or the like is poured into a tundish, and from the tundish, the molten steel 1 is poured into a mold consisting of steel belts 3 and 4 on the upper and lower surfaces and steel blocks 5 on both sides.
is injected. The injected molten steel is cooled and solidified by the steel belts 3 and 4, which are cooled by a large amount of cooling water 8 flowing out on the back side of the steel belts 3 and 4, and by the steel block 5. When a thin slab is continuously cast by this twin-belt continuous casting machine, the thin slab 8 is in a completely solidified state immediately after passing through the lower belt support roller 6.

The slab is completely solidified in the secondary cooling zone unit.

ばならない。(Problems to be Solved by the Invention) The temperature of the slab coming out of the mold of the above-mentioned twin-belt continuous casting machine or at the outlet of the secondary cooling zone unit is not the same at the center of the slab. This is near the freezing point, and the surface of the slab is at a temperature of 750°C to 850°C because heat is removed by the steel belt or the support rolls of the secondary cooling zone unit. For this reason, in the next hot rolling process, it is not possible to secure the amount of heat in the slab required to smoothly roll the thin slab, and the thin slab must be reheated immediately before hot rolling. No.

じる。 In addition, in a twin-belt continuous casting machine equipped with a secondary cooling zone unit, the support roll of the secondary cooling zone unit is an insulating roll to prevent the surface temperature of the slab from dropping when solidification is completed. By doing so, it is possible to secure the heat held by the slab. However, problems arise such as the life of the heat insulating roll is shortened, or the frame constituting the secondary cooling zone unit needs to be water-cooled, which increases running costs and construction costs.

ればならない。 As mentioned above, in order to prevent bulging of thin slabs that come out of the mold in an unsolidified state, if a secondary cooling zone unit such as a support roll, shoe, or walking beam is used, the support roll, etc. The slabs come into contact and the surface temperature of the slabs decreases. Furthermore, when the slab is completely solidified in the mold and then pulled out, the heat is removed through the steel belt, which causes the problem of a drop in the surface temperature of the slab. The pieces must be reheated.

An object of the present invention is to provide a method for continuously casting thin slabs using a belt type continuous casting machine.

を特徴とする双ベルト式連続鋳造方法である。(Means for Solving the Problems) The present invention has a long side of a mold consisting of a pair of metal belts arranged opposite to each other and movable in rotation, and short sides of the mold each provided at both edges of the metal belt. Molten metal is injected into the casting space of a twin-belt continuous casting machine having the above-described casting space, and the molten metal is cooled and solidified mainly through a metal belt, and the metal belt is rotated to form a slab. In the continuous casting method, a heat insulating layer is formed in the longitudinal direction of a metal belt, and the formation is divided into a region where the heat insulating layer is thick and a region where the heat insulating layer is thin or a heat insulating layer is formed in the width direction of the belt. When the belt is rotated, the belt is divided into a region where no heat insulating layer is formed, and at least both side edges of the belt near the short sides of the mold have a thin layer or a region where no heat insulating layer is formed. The molten metal remains inside the slab in the thickness direction of the slab that has been cooled in the thick area of the heat insulating layer at the side end, while the slab is cooled in the area where the heat insulating layer is thin or does not form a heat insulating layer. This is a twin-belt continuous casting method characterized by completely solidifying the molten metal within the thickness direction.

を吹き付けるようにする。 To provide the heat insulating layer, for example CaCO 3 ,
A material whose main components are SiO 2 and Al 2 O 3 suspended in water or isopropyl alcohol is used as a coating material to prevent the heat insulating layer from peeling off from the surface of the steel belt even when the steel belt is bent. An inorganic binder such as water glass or an organic binder is added to the binder. This coating material is sprayed at a wide angle onto the steel belts 3 and 4 by a plurality of spray nozzles 12 arranged in the width direction of the steel belts 3 and 4, as shown in FIG. To adjust the thickness of the heat insulating layer, that is, to separate thick and thin regions of the heat insulating layer, the spray nozzle 12 is replaced to adjust the amount of coating material discharged. After applying the coating material, blow warm air at 150℃.
After spraying at a flow rate of 25 m 3 /min to dry the coating material on the steel belt and form a heat insulating layer on the steel belt, the steel belts 3 and 4 on which this heat insulating layer is formed are Contact with molten steel. Before spraying the coating material, the steel belts 3 and 4 are drained and polished using a rotating brush, and the coating material is sprayed onto the drained and polished surface of the steel belt using a spray nozzle.

能とする。 As described above, the areas where the heat insulating layer is thick on the steel belts 3 and 4 on which the heat insulating layer is formed have a smaller amount of heat removed than the areas where the heat insulating layer is thinner, and solidification is delayed. For example, if a heat insulating layer 9 is formed on the steel belts 3 and 4 as shown in FIG. 3, a thick part and a thin part of the solidified shell will be formed as shown in FIG. As the slab moves to
Coagulation progresses. At the point when the slab passes through the belt support rollers that support and rotate the steel belt, the thick part of the solidified shell is completely solidified, and the part where the solidified shell is not fully developed, that is, the thin part of the solidified shell, is solidified. It is in an unsolidified state. The remaining unsolidified slab completely solidifies just below the next pinch roll, but the latent heat during this solidification contributes to raising the surface temperature of the slab, reheating the slab. This enables hot rolling without the need for rolling.

なる。 In addition, the amount of bulging in the slab depends on the length in the width direction of the solidified shell, which is subjected to static iron pressure, so if this length is shortened, the amount of bulging will be reduced, leaving an unsolidified part inside the slab. However, the amount of bulging in the slab is reduced to such an extent that it does not become a problem. For this,
Mechanical support mechanisms such as support rolls and shoes to suppress the bulging of the slab are no longer required.

It was cast into a thin slab with a width of 1000 mm. At this time, the thickness
