SLAG-REMOVAL EQUIPMENT
To provide a slag-removal equipment capable of properly preventing erosion of a raking plate by properly setting a refractory coverage range for the raking plate and of preventing a weight increase of the raking plate.SOLUTION: A slag-removal equipment 1 is attached at a tip of a raking arm 18 with a raking plate 30 that rakes out a slag S floating in a surface of a molten metal M within a molten-metal vessel 50, which the raking plate 30 is configured by a quadrangular plate extending in longitudinal and vertical directions. The raking plate 30 is provided with a refractory 34 covering a front face 30a and a rear face 30b, a left side face 30e and a right side face 30f, and a lower end surface 30d in a lower part of the raking plate 30. The coverage range R of the refractory 34 over the raking plate 30 is 30 mm or greater and 300 mm or smaller from a bottom edge of the raking plate 30.SELECTED DRAWING: Figure 2
【課題】耐火物の掻き出し板に対する被覆範囲を適切に設定して掻き出し板の溶損を適切に防止できるとともに掻き出し板の高重量化を防止できる除滓装置を提供する。【解決手段】除滓装置１は、掻き出しアーム１８の先端に溶融金属容器５０内の溶融金属Ｍの表面に浮遊するスラグＳを掻き出す掻き出し板３０を取付け、掻き出し板３０が左右方向及び上下方向に延びる四角形状の平板で構成される。掻き出し板３０に、掻き出し板３０の下部の前面３０ａ及び後面３０ｂ、左側面３０ｅ及び右側面３０ｆ、及び下端面３０ｄを被覆する耐火物３４を設ける。耐火物３４の掻き出し板３０に対する被覆範囲Ｒは、掻き出し板３０の下端から３０ｍｍ以上３００ｍｍ以下である。【選択図】図２
