Description
【０００１】[0001]
本考案はＬＦ等に用いられる取鍋の側壁構造に関するものである。 The present invention relates to a side wall structure of a ladle used for LF and the like.
【０００２】[0002]
従来、図２に示すように取鍋の側壁(1) は最外殻が鉄皮(2) でその内側に裏張 りシャモット層(3) が配置され、更にＭg Ｏ−ＣあるいはＭg Ｏ−Ａl2Ｏ3 −Ｃ 等からなる耐火層(4) （例えば厚み１１４mm）がその内側に配置されている。そ して溶融物の液面が位置する範囲、即ちスラグライン領域の耐火層(4A)の肉厚は 例えば１５０mmと増大され、更にスラグライン領域の上下の耐火層(4B)の肉厚も 例えば１３０mmと増大されて、スラグライン付近での損耗に対処している。Conventionally, as shown in FIG. 2, a side wall (1) of a ladle has a steel shell (2) as an outermost shell, a chamotte layer (3) is lined inside the shell, and further, MgO-C or MgO-. A refractory layer (4) (for example, 114 mm in thickness) made of Al 2 O 3 —C or the like is arranged inside thereof. Then, the thickness of the refractory layer (4A) in the range where the liquid level of the melt is located, that is, the slag line region is increased to, for example, 150 mm, and the thickness of the refractory layers (4B) above and below the slag line region is also increased, for example. Increased to 130mm to deal with wear near the slag line.
【０００３】[0003]
しかしながら上記従来の構成ではスラグライン領域の耐火層(4A)とその下側の 耐火層(4B)との厚みが相違して段部(5,6) が形成され、該段部(5,6) に溶融物が 衝突し、この部分が特に大きく損耗されると云う問題があった。 However, in the above-mentioned conventional configuration, the thickness of the refractory layer (4A) in the slag line region and the thickness of the refractory layer (4B) below the slag line region are different from each other, and the step portions (5, 6) are formed, and the step portions (5, 6) are formed. There was a problem that the melt collided with), and this part was particularly worn.
【０００４】[0004]
本考案は上記従来の課題を解決するための手段として、取鍋側壁(11)の耐火層 (14)のスラグライン領域ＳＬおよびスラグライン領域ＳＬの上下領域の肉厚を均 一に増大せしめた取鍋側壁構造を提供するものである。 As a means for solving the above-mentioned conventional problems, the present invention uniformly increases the wall thickness of the slag line region SL of the refractory layer (14) of the ladle side wall (11) and the upper and lower regions of the slag line region SL. A ladle sidewall structure is provided.
【０００５】[0005]
本考案では取鍋の側壁(11)の耐火層(14)の肉厚をスラグライン領域ＳＬおよび スラグライン領域ＳＬの上下領域にわたって均一に増大させてあるので、スラグ ライン領域ＳＬの下側に段部が形成されないので、段部に溶融物が当たってこの 部分が大きく損耗されることがない。 In the present invention, the wall thickness of the refractory layer (14) on the side wall (11) of the ladle is uniformly increased over the slag line region SL and the upper and lower regions of the slag line region SL. Since the part is not formed, the melt does not hit the step part and this part is not greatly worn.
【０００６】[0006]
本考案を図１に示す一実施例によって説明すれば、取鍋の側壁(11)は鉄皮(12) 、その内側の裏張りシャモット層(13)、更にその内側のＭg Ｏ−ＣあるいはＭg Ｏ−Ａl2Ｏ3 −Ｃ等からなる耐火層(14)からなり、スラグライン領域ＳＬおよび スラグライン領域ＳＬの上下領域の耐火層(14A) は均一に増大せしめられており 、例えば耐火層(14A) の厚みは１３０mmである。The present invention will be described with reference to an embodiment shown in FIG. 1. The side wall (11) of the ladle is an iron skin (12), a chamotte layer (13) inside the ladle, and MgO-C or Mg inside the ladle. The refractory layer (14) made of O-Al 2 O 3 -C or the like, and the slag line region SL and the refractory layer (14A) above and below the slag line region SL are uniformly increased. The thickness of 14A) is 130 mm.
【０００７】 上記構成では操業７５回で取鍋側壁(11)の耐火層(14)は点線位置まで略均一に ３０mm程度損耗し更なる操業も可能であるが、図２に示す従来例では点線に示す ように操業７０回でスラグライン領域ＳＬの耐火層(4A)の厚みが本実施例の耐火 層(14A) の厚みよりも大きいにもかゝわらず特にスラグライン領域ＳＬの下側の 耐火層(4,4B)の損耗が大きく、最大損耗量は５０mmにも達し、吹付補修が必要と なる。In the above configuration, the fireproof layer (14) of the ladle side wall (11) is worn approximately 30 mm to the dotted line position even after 75 operations and further operation is possible, but in the conventional example shown in FIG. As shown in Fig. 7, even after 70 operations, the thickness of the refractory layer (4A) in the slag line area SL is larger than the thickness of the refractory layer (14A) of the present embodiment, but especially in the lower side of the slag line area SL. The wear of the refractory layer (4, 4B) is large, the maximum wear amount reaches 50 mm, and spray repair is required.
【０００８】[0008]
したがって本考案では耐火層の厚みを低減しても、耐火層の寿命が長くなって 補修の頻度も少なくなる。 Therefore, in the present invention, even if the thickness of the refractory layer is reduced, the life of the refractory layer is extended and the frequency of repairs is reduced.
