Description of the Related Art As the solidification of steel progresses (solidification shell formation) and the temperature decreases (solidification shell growth), the volume of the solidified shell portion shrinks compared to the volume when it is in a liquid phase. In general, the cross-sectional area of the continuous casting mold is smaller in the lower part than in the upper part (= it means that a positive taper is given). However, in a mold for steel slabs, an assembling method of assembling four wall surfaces, particularly a method of sandwiching a pair of opposing short side wall surfaces with other opposing long side wall surfaces, is generally used. Tapered only. Various settings can be made for the short-side taper amount as in some prior examples.

Are also disclosed. Here, when the conditions other than the casting speed are the same, comparing the thickness of the solidified shell at the lower end of the mold, the lower the casting speed, the thicker the shell thickness, and the larger the shrinkage of the solidified shell portion as a whole. Therefore, it is necessary to increase the taper amount of the mold. The case where the casting speed is low is, for example, the initial stage of casting.

In this case, if the amount of the mold taper is not reduced, the pull-out resistance becomes excessively large, and the pull-out becomes impossible or the slab breaks out. Furthermore, in the actual operation, the progress of solidification in the mold changes every moment due to the use and consumption of the powder for continuous casting, the molten steel component, the amount of primary cooling water, the water pressure, and the like. Ideally, make it smaller or change it.

45 discloses a technique for changing the taper of the meniscus portion on the short side wall surface. As a result, it has been reported that corner vertical cracks are reduced and the amount of heat released from the mold is increased. Various contrivances have been proposed as far as the short side wall surface is tapered.

In the case of applying, a method is conceivable in which a short side wall surface in which the upper and lower widths are continuously changed is manufactured, and the side is sandwiched between a pair of opposing long side wall surfaces.

を得ることは困難であった。However, in this method, only one type of taper can be provided in advance. In addition, when the vertical width of the short side wall surface is different, the gap between the side surface of the short side wall surface and the long side wall surface is kept constant. The problem arises that the amount of taper must be changed. The short side wall surface and the long side wall surface are not preferable because the cooling conditions are different. That is, cooling could not be properly maintained according to the steel type and casting speed, and as a result, it was difficult to obtain a sound solidified shell at the lower end of the mold.

It is in. That is, regardless of whether the vertical width of the short side wall surface is different or not, the cooling of the corner portion is not required to keep the dimension of the gap between the side surface of the short side wall surface and the long side wall surface constant in the casting direction. The gist of the present invention is based on the finding that there is no adverse effect on the following.

性は極めて少ない。The point of the present application is that the taper amount of the long side wall surface is freely changed regardless of the vertical width of the short side wall surface. Conversely, the dimension of the gap between the side surface of the short side wall surface and the long side wall surface is designed to have different sizes in at least a part of the casting direction. That is, the displacement of the taper adjusting cylinder 5 varies depending on the total length of the continuous casting mold 1, the type of steel to be cast, the casting speed range, and the like.
In the current continuous casting method, it is at most about 1 mm,
The dimension of the gap between the side surface of the short side wall surface and the long side wall surface is 0.5
When the distance exceeds mm, the danger of hot water leakage and breakout is extremely small.

差し支えない。However, as compared with the method in which the upper side of the mold is widened when the long side taper is increased as shown in FIG. 1 (a method in which a gap is formed above the mold), the width of the short side wall surface is previously reduced as shown in FIG. If the taper is reduced by increasing the distance between the long side walls below the mold to reduce the amount of taper, or if the long side wall is completely adhered to the side of the short side, the amount of taper can be increased. However, it is preferable from the viewpoint of hot water leakage. In any case, the slab thickness immediately below the mold is 1
mm, and no special measures need to be taken for the arrangement of the rolls in the secondary cooling zone. Of course, a mechanism capable of changing the roll interval in synchronization with the taper change may be incorporated.

全体が非常にコンパクトになるという特徴を持つ。FIG. 3 shows an example in which a gap is formed below the mold when the taper amount of the long side is reduced as in FIG. 2, but the taper amount of the long side is adjusted by controlling the shape memory alloy 12 and the signal of the control device 11 around the shape memory alloy 12. An example comprising the temperature control device 13 controlled by the following is shown. 2 except that a shape memory alloy is used instead of the taper adjusting cylinder. The feature here is that the whole mold is very compact compared to the taper adjusting cylinder 5.

を増大させて対処する（図４）。An example of a thermocouple 7 or a heat flux meter 8 in the mold is shown on the long side wall surface as an information collecting device in the mold. The mold temperature is measured by the thermocouple 7 embedded in the mold. By analyzing the fluctuation, it is possible to determine whether or not an air gap has been generated in the mold. For example, when the temperature of the thermocouple decreases, it indicates that an air gap is gradually generated. Therefore, a decrease in the temperature detected by the thermocouple is dealt with by increasing the taper of the long side wall surface of the mold (FIG. 4).

となる。As an actual control sequence, information obtained by performing a moving average process on a mold temperature detected by a thermocouple is used. Further, a heat flux meter 8 may be used instead of the thermocouple 7. If the calculated value of the heat flux decreases, it indicates that an air gap is gradually generated. For this, measures such as increasing the taper amount are taken. As a result, it is possible to increase the heat removal and perform appropriate cooling.

It is necessary to take measures to reduce the taper amount of the long side wall surface. The taper amount to be increased or decreased according to the detected data amount needs to be set according to the casting conditions such as the drawing speed and the type of mold lubricating flux, the mold cooling efficiency variable width, and the like. The information processing is performed by the arithmetic unit 1
0, and the displacement of the taper adjusting cylinder 5 is adjusted via the control device 11 using the result.

Here, the thermocouple information embedded in the casting direction on the long side, the taper amount on the long side, and the data of the solidified shell thickness immediately below the mold obtained by adding sulfur in the mold are shown. Here, an example is shown in which a cylinder is arranged below the mold and the long-side taper is changed based on the change of the thermocouple in the mold.

った（図４）。Even if the speed decreases at the seam, the thermocouple embedded in the mold is stable, the resulting change in the solidified shell thickness is very small, and the shell thickness is small enough to hinder operation. No portion or conversely, an excessive portion occurred (FIG. 4).

５）。On the other hand, in the case of a normal mold, an abnormal operation such as an abnormal lowering of the thermocouple at the lower portion of the portion where the speed of the joint is reduced is observed, and the change in the thickness of the solidified shell is remarkable.
The situation was very unstable. Furthermore, at high speeds, there were many operational problems, such as insufficient solidification shell pressure immediately below the mold, causing fluctuations in the unsteady bulging property of the molten metal surface (FIG. 5).

性の向上にもつながる。The thickness of the solidified shell on the long side can be ensured by changing the taper on the long side during casting, and the shell thickness changes based on the air gap generation in the mold due to the change in steel type and casting speed. Can be reduced as quickly as possible. This effect can dramatically improve the stability of casting. Further, since the change in casting speed at the seam can be reduced, the average casting speed is improved, which leads to an improvement in productivity.
