３をモルタル１４を介在し嵌着して構成されている。Conventionally, as shown in FIG. 2, plate bricks for this type of sliding gate have a rectangular plate-shaped plate body 10 made of a refractory material with excellent corrosion resistance and strength, and on one side, a connection part with a nozzle or the like is provided. The plate main body 10 is integrally formed with a dowel portion 11 and has a protruding dowel portion 11.
An iron skin 12 is attached to the surface of the dowel part 11, and an iron ring 1 is attached to the outer periphery of the end of the dowel part 11 to prevent cracks in the dowel part 11 from expanding.
3 are fitted together with mortar 14 interposed therebetween.
図中１５は溶融金属が流通する排湯孔である。In the figure, 15 is a drain hole through which molten metal flows.

えている。However, in the above-mentioned conventional sliding gate plate brick, although the iron ring 13 can prevent the expansion of cracks that occur in the dowel portion due to thermal history, the iron ring 13 and the iron sheath on the surface of the plate body 10
Air leaks occur through cracks in the bricks between the two, which has a major negative impact on the quality of the casting and the stability of operations.
かかる傾向は、スライディングゲートの多数回使用にお
いて一層顕著となっている。This tendency becomes more noticeable when the sliding gate is used many times.
そこで、本発明は、れんがの割れに起因するエアーリー

の）足イ共を目的とする。SUMMARY OF THE INVENTION Therefore, the present invention aims to provide a sliding gate plate and brick legs that can prevent air leaks caused by cracks in the bricks.
前記課題を解決するため、本発明のスライディングゲー
トのプレートれんがは、プレート本体のダボ部突設側の
片面に鉄皮を装着したスライディングゲートのプレート
れんがにおいて、前記鉄皮をダボ部の全外周を覆うよう
に延在させたものである。In order to solve the above problem, the plate brick for a sliding gate of the present invention is a plate brick for a sliding gate in which an iron sheath is attached to one side of the dowel portion protruding side of the plate body, and the iron sheath is attached to the entire outer periphery of the dowel portion. It is extended to cover.
（作 用〕
上記手段においては、ダボ部の全外周面及びこれに連な
るプレート本体の片面が鉄皮によって気密に被覆される
。(Function) In the above means, the entire outer circumferential surface of the dowel portion and one side of the plate body connected thereto are airtightly covered with the iron skin.
以下、本発明の一実施例を第１図と共に説明する。 An embodiment of the present invention will be described below with reference to FIG.
図中１は耐食性、耐熱性、耐久ポーリング性、強度等に
優れた耐火物によって形成された短形板状のプレート本

貫通して溶融金属が流通する排湯孔３が設けられている
。In the figure, 1 is a rectangular plate-shaped plate body made of a refractory material with excellent corrosion resistance, heat resistance, durable poling property, strength, etc. On one side, a truncated conical dowel part 2 is integrally protruded. A drain hole 3 is provided in the center of the dowel portion 2, through which molten metal flows through the plate body 1.
そして、ダボ部２が突設されたプレート本体１の片面及
びダボ部２の全外周面には、鉄皮４がモルタル５を介在
させて装着されている。An iron skin 4 is attached to one surface of the plate body 1 from which the dowel portion 2 is protruded and to the entire outer peripheral surface of the dowel portion 2 with mortar 5 interposed therebetween.

なってコストの合理化にもつながった。According to the sliding gate plate brick having the above configuration, although the cracks in the dowel portion 2 are somewhat enlarged due to cooling after use, air blowing is not seen as in the conventional case, and cracks on the inner surface of the drain hole 3 are not observed. The product is in good condition with no problems such as V-shaped melt damage or dowel leakage, and can be used many times, leading to cost rationalization.

。(Effects of the Invention) According to the present invention as described above, the entire outer circumferential surface of the dowel portion and one side of the plate body connected thereto are airtightly covered with the iron skin, so air leaks caused by cracks in the bricks can be completely prevented. It is possible to prevent this, and as a result, the quality of the cast product can be improved, and the operation can be stabilized.
