Abstract

PURPOSE:To prevent the decrease in the life of a mold owing to a quenching crack or the like in a mold having a water cooling jacket by inserting and fitting the outside circumference of the mold on the field nozzle side to the mounting plate of the jecket. CONSTITUTION:A sleeve type mold 2 is mounted by means of a fixing plate 7 and bolts 6 to a mold jacket 4. The field nozzle 1 side of the mold 2 is inserted and fitted into the opening 5' of the mounting plate 5 of the jacket 4. The opening 5' is less stressed by the thermal expansion of the mold and is scarcely cracked by quenching, etc. The life of the mold 2 is thus considerably prolonged and the cost of production is reduced.

Description

【発明の詳細な説明】 この発明は、水平連続鋳造機用モールドに関するもので
イつる。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mold for a horizontal continuous casting machine.

Ｆ内に鋳込み、冷却しながら引き抜く、所謂水平連続鋳
造機が開発され、た。In recent years, in place of the so-called vertical continuous casting machine that draws the molten steel from the tundish downward, a casting nozzle is installed horizontally at the bottom of the side wall of the tundish, and the mold is inserted into the nozzle, mainly for the purpose of reducing construction costs. A so-called horizontal continuous casting machine has been developed, in which the molten steel in the tundish is connected horizontally to the mold F through the nozzle, and is then drawn out while being cooled.

品コストが高かった。The molds of the horizontal continuous casting machines have conventionally been formed with end flanges and are secured to a mold jacket via these seven flanges for cooling the mold. For this reason, when the end of the mold 1 undergoes thermal expansion due to high temperatures during casting, the expansion is restrained by the flange, which tends to cause quench cracking and shortens the life of the mold. Furthermore, since the flanged mold was manufactured by cutting the solid material, the product cost was extremely high.

定されていることに特徴を有する。In a mold that is cooled by a mold jacket provided on one outer periphery that is horizontally attached to a lower part of a side wall of a tanditsh through a feed nozzle U7, one end of the mold on the feed nozzle side is shaped like a straight tube, and the one end is inserted into the opening of an annular mounting plate fixed to one end of the mold jacket, and the curved end of the mold is fixed to the curved end of the mold jacket. .

この発明の実施例を図面を参照しながら説明する。Embodiments of the invention will be described with reference to the drawings.

第１図は、この発明の一実施態様を示す断面図である。FIG. 1 is a sectional view showing one embodiment of the present invention.

けられたモールド冷却用のモールドジャケットである。In Fig. 1, 1 is a mold horizontally attached to the foot nozzle 1 through a brake ring 3, and 4 is a mold installed horizontally at the bottom of the side wall of a tanditsh (not shown). This is a mold jacket for cooling the mold attached to the outer periphery of the mold 2.

モールド２のフィー　ドノズル１側の一端部は直管状を

入されている。One end of the mold 2 on the side of the feed nozzle 1 has a straight tube shape, and the one end is inserted into an opening 5' of an annular numeral plate 5 fixed perpendicularly to one end of the mold jacket 4. .

モールド２の他端部は、モールドジャケットの曲端部に

よシ固定されている。The other end of the mold 2 is fixed to an annular fixing plate 7, which is fixed to the curved end of the mold jacket with bolts 6, by a concave-convex fit.

鋳造中にモールド２は高温になるが、特１−モールド２
の人口部分はより高温となる。この結果。Mold 2 becomes high temperature during casting, but special 1-mold 2
The population part of the area will experience higher temperatures. As a result.

モールド人口部分は他の部分に比べて大きく熱膨張する
が、モールド端部は何ら拘束さ力、てｌＪＮなし）ので
、自由にフィードノズル１個に膨張する一方。The mold population part thermally expands more than other parts, but the mold end part is free to expand into one feed nozzle because there is no restraint force.

鋳造が終了すると元の状態に収縮する。従って。Once casting is complete, it will shrink back to its original state. Therefore.

モールド２の膨張、収縮による焼割れは生じず、寿命が
犬「１］に延びる。No quenching cracks occur due to expansion and contraction of the mold 2, and the life span is extended to 1.

果かもたらさハ５る。As explained above, according to the present invention, the life of the mold can be extended by 140 days because it is difficult to cause cracking during firing, and since there is no sifting flange unlike conventional molds, it can be manufactured almost in the same way as ordinary pipe materials. can do. Therefore, a useful effect is brought about, such as the production cost can be greatly reduced in acidity.
