る。 The cutting and removing device of this embodiment is a converter A shown in Fig. 3.
The arc-shaped cutting blade circumscribing the tilting locus Z of the furnace mouth B, more precisely, the tilting locus Z of the furnace mouth periphery C, is
As shown in the figure, it is composed of three divided blades 1a, 1b, and 1c, and when the converter is in the slag removal position with the furnace mouth B directly below as shown in Figure 3, the drive motor 11a is driven. The cutting tools 2a, 2b, 2c are advanced respectively, and the divided blades 1a, 1b, 1 of each cutting tool are moved forward.
c is stopped at a cutting position Y where the tip 12 of the cutter c circumscribes the driving locus Z of the furnace mouth periphery C. After the slag has been removed, the converter is tilted in the direction of the arrow W in FIG. 3, and during the tilting until it returns to the upright position, the deposits D on the furnace mouth contact the divided blades 1a, 1b, and 1c, and are cut and removed.
ところで、炉口付着物Ｄは炉口全周に均一高さ
に付着していることはなく必ず凹凸面になつてい
る。従つて切削刃を切削位置Ｙに固定した場合に
は付着物の凹部では切削抵抗が小さく、凸部では
切削抵抗が大きい。 Incidentally, the furnace mouth deposits D are not attached to the entire circumference of the furnace mouth at a uniform height, but always form an uneven surface. Therefore, when the cutting blade is fixed at the cutting position Y, the cutting resistance is small in the concave portions of the deposit, and the cutting resistance is large in the convex portions.

多かつた。 Using the cutting and removing device of this example, the divided blade 1
a, 1b, and 1c were operated separately, and were moved backward when cutting convex portions of deposits on the furnace mouth, and moved forward when cutting concave portions to cut and remove deposits to an appropriate thickness. The amount removed by cutting was larger than the amount removed by a single cutting blade.
尚、各分割刃の前進、後退を油圧モータ等を用
いて自動化すると操作人員を減少できる。尚分割
刃の数は３個に限定されるものではない。 Note that the number of operating personnel can be reduced by automating the advancement and retraction of each divided blade using a hydraulic motor or the like. Note that the number of divided blades is not limited to three.

According to the present invention, the arc-shaped cutting blade circumscribing the tilting locus of the converter mouth is composed of a plurality of divided blades, and each divided blade is supported separately so as to be able to move forward and backward with respect to the converter. This allows the cutting blade to move forward or backward depending on the cutting resistance of the deposits, in other words, the height, which prevents the converter from tilting or damage to the converter or the cutting removal device. This has the effect of improving removal efficiency.
