本発明は転炉の傾動力を用い弧状切削刃で炉口
付着物を切削除去する装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for cutting and removing deposits on the furnace mouth using an arcuate cutting blade using the tilting force of a converter.

A conventional device for cutting and removing deposits on the furnace mouth using the tilting force of a converter has an arc-shaped fixed cutting blade surrounding the converter, as disclosed in, for example, Japanese Utility Model Publication No. 55-24129. This device uses the driven power of the furnace to cut and remove deposits on the furnace mouth using the arc-shaped fixed cutting blade when the converter is tilted.

点がある。
The conventional cutting and removal device described above cuts and removes the deposits on the furnace mouth in the manner described above, so when the deposits on the furnace mouth have low cutting resistance or the height of deposits is low. When the cutting resistance is small, such as when the cutting resistance is low, the deposits on the furnace mouth can be removed without any problem, but when the deposits on the furnace mouth have a property of high cutting resistance, or when the deposit height is high, the cutting resistance is large. The disadvantage is that sometimes the converter cannot be tilted or the converter cutting and removal equipment is damaged.

In order to solve the above-mentioned problem, the present invention is characterized in that it has a configuration in which a plurality of groove cutting blades are made to protrude beyond the arcuate cutting blades and are provided at approximately right angles toward the converter trunnion axis.

前進、後退させられる。 As shown in FIGS. 1 and 2, in the cutting and removing device of this embodiment, the handle 5 is slid by the rollers 4 of the guide roller box 3 hanging down from the pedestal 2 hanging down from the lower surface of the converter working floor 1. A cutting tool 8 is freely supported and has an arcuate cutting blade 6 and a plurality of groove cutting blades 7 at the tip of the handle 5. The converter is moved forward and backward relative to the converter by a drive motor 12 that is connected via a drive shaft 10 having gears (not shown) and a speed reducer 11 .

The cutting blade 6 protrudes beyond the cutting blade 6 on the side facing the deposits C of the furnace mouth B of the converter A, and as shown in FIG.
3 is provided to protrude further forward (in the direction of the converter) than the arcuate cutting blade 6, and the tip 13 of the groove cutting blade 6 and the tip 14 of the arcuate cutting blade 6 are both circumscribed by the tilting locus Z of the converter mouth. Furthermore, the groove cutting blade 7 is provided substantially perpendicularly to the trunnion shaft 15 of the converter (FIG. 4), in other words, parallel to the advancing and retreating direction of the cutting tool 8 (FIG. 1).

As shown in the figure, it was placed diagonally to the lower right of the trunnion shaft of the converter. Then, the cutting tool 8 is advanced to the position shown in FIG. As shown in FIG. 3, the deposit C first comes into contact with the grooving blade 7, and as shown in FIG. The deposits are removed in the form of strips or divided strips parallel to the tilting direction of the converter.

去できた。 The deposits cut by the arcuate cutting blade 6 are sequentially bent in the direction away from the furnace mouth, but the cutting and removal device of this embodiment cuts the deposits in the groove 15 before cutting with the arcuate cutting blade 6.
Since the cutting blade 6 is cut, the bending resistance of the deposits applied to the cutting blade 6 is reduced, and the thickness of the cut that would make it impossible to tilt the converter using a conventional cutting/removal device can be removed.
さらに溝切り刃を転炉のトラニオン軸にほぼ直
角に設けたことも切削抵抗の減少に寄与した。 Furthermore, the fact that the grooving blade was installed almost perpendicular to the trunnion axis of the converter also contributed to the reduction of cutting resistance.

According to the present invention, in addition to the conventional arcuate cutting blade, a plurality of groove cutting blades are made to protrude beyond the arcuate cutting blade,
Moreover, it is arranged almost at right angles toward the converter trunnion axis, which reduces the bending resistance of the deposits when cutting and removing the deposits, and has the effect of preventing the converter from being tilted or damage to the converter and the cutting/removal device. .
