この発明は、連続鋳造設備における鋳型に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mold for continuous casting equipment.
近年、鋼を連続鋳造するに際し、連続鋳造設備の鋳型（
モールド）内に、電磁攪拌装置を設置して、鋳片の未凝
固部分を電磁攪拌し、これによつて、偏析等の発生を防
止し、かくして、良好な鋳片を得ることが行われている
。In recent years, when continuously casting steel, the mold of continuous casting equipment (
An electromagnetic stirring device is installed inside the mold to electromagnetically stir the unsolidified portion of the slab, thereby preventing the occurrence of segregation, etc., and thus obtaining a good quality slab. There is.
上記鋳型は、第１図に示すように、鉄心１にコイル（図
示せず）を配設したものて構成される電磁攪拌装置２が
、木箱３間に設置され、鋳型壁５の溶鋼４側外壁面５’
に溶鋼冷却用銅板６が取付けられているもので構成され
ている。In the mold, as shown in FIG. 1, an electromagnetic stirring device 2 consisting of an iron core 1 and a coil (not shown) is installed between wooden boxes 3, and the molten steel on the mold wall 5 is Side outer wall surface 5'
A copper plate 6 for cooling molten steel is attached to the molten steel.
上記銅板６の鋳型壁外壁面５’側には、第１図中点線で
及び第１図のＡ−Ａ線断面図である第２図に示すように
縦方向に溝７が複数本形成されていて、木箱３からの冷
却水がこの溝７内を流通−し、これによつて、銅板６が
冷却されるようになつている。On the mold wall outer wall surface 5' side of the copper plate 6, a plurality of grooves 7 are formed in the vertical direction, as shown by the dotted line in FIG. 1 and in FIG. Cooling water from the wooden box 3 flows through the groove 7, thereby cooling the copper plate 6.
ところが、上記構造の鋳型において、銅板６の冷却効果
を向上させるためには、溝７の深さｄを深くするか、溝
７の数を増加して冷却水の流量を増す必要があるが、溝
７の深さｄを深くすると、銅板６全体の厚さａが厚くな
る結果、磁束の減衰は免れず、一方、溝７の数を増すと
、強度的に問題が生じる。However, in order to improve the cooling effect of the copper plate 6 in the mold having the above structure, it is necessary to increase the flow rate of cooling water by increasing the depth d of the grooves 7 or by increasing the number of grooves 7. Increasing the depth d of the grooves 7 increases the overall thickness a of the copper plate 6, which inevitably causes attenuation of the magnetic flux.On the other hand, increasing the number of grooves 7 causes problems in terms of strength.
この発明は、上述のような観点から、鋳型壁の’銅板が
取付けられている外壁面及び銅板側に、複数本の溝を夫
々形成し、これらの溝を合わせて、１つの溝にしたこと
に特徴を有する。From the above-mentioned viewpoint, the present invention is to form a plurality of grooves on the outer wall surface of the mold wall where the copper plate is attached and on the copper plate side, and to combine these grooves into one groove. It has the following characteristics.
この発明を実施例により図面を参照しながら説明する。The present invention will be described by way of examples with reference to the drawings.
第３図は、この発明の鋳型の要部断面図である。第３図
に示すように、この発明の鋳型は、その鋳型壁５の銅板
６が取付けられている外壁面５’側に溝７が複数本形成
され、銅板６にも、前記溝７と合致する位置に、溝７’
が複数本形成されていて、溝７と７’とを合せて、１つ
の冷却水流通用の溝になつている。FIG. 3 is a sectional view of essential parts of the mold of the present invention. As shown in FIG. 3, the mold of the present invention has a plurality of grooves 7 formed on the outer wall surface 5' side of the mold wall 5 to which the copper plate 6 is attached, and the copper plate 6 also matches the grooves 7. groove 7'
A plurality of grooves 7 and 7' are formed, and the grooves 7 and 7' together form one cooling water circulation groove.
その他の構造は、第１図に示した従来の鋳型と同様であ
る。このように、冷却水流通用の溝を、鋳型壁５と銅板
６とに分けて形成したので、溝の断面積は、従来の溝の
断面積と同様にすることができ、しかも、銅板６側に形
成した溝７″の深さｄ″は、従来の溝の深さｄに比べて
浅く形成できるので、銅板６の厚さをそれだけ薄くする
ことができる。The rest of the structure is similar to the conventional mold shown in FIG. In this way, since the grooves for cooling water circulation are formed separately in the mold wall 5 and the copper plate 6, the cross-sectional area of the grooves can be made similar to the cross-sectional area of conventional grooves. Since the depth d'' of the groove 7'' can be made shallower than the depth d of a conventional groove, the thickness of the copper plate 6 can be reduced accordingly.
従つて、磁束の減衰を防止できるので、効率良く電磁攪
拌を行うことができる。尚、鋳型壁５を非磁性体で構成
すれば、よソー層の磁束の減衰防止効果を得ることがで
きる。Therefore, since attenuation of the magnetic flux can be prevented, electromagnetic stirring can be performed efficiently. Incidentally, if the mold wall 5 is made of a non-magnetic material, the effect of preventing the magnetic flux of the sowing layer from attenuating can be obtained.
以上説明したように、この発明によれば、銅板冷却用の
冷却水が流通する溝を、鋳型壁と銅板とに形成した溝同
士を合せたもので構成することによつて、銅板の厚さを
薄くすることができるので、それだけ、磁束の減衰を防
止でき、効率良い電磁攪拌が行えるといつた、きわめて
有用な効果がもたらされる。As explained above, according to the present invention, the thickness of the copper plate can be reduced by forming the groove through which cooling water for cooling the copper plate flows by combining the grooves formed in the mold wall and the copper plate. Since the thickness of the magnetic flux can be made thinner, it is possible to prevent the attenuation of the magnetic flux and achieve extremely useful effects such as efficient electromagnetic stirring.
