(57) [Abstract] [Purpose] To provide a mold structure that can demonstrate the lubricating function of graphite material by eliminating the use of copper material from the cooling mold for overlaying composite materials. [Structure] By fitting a graphite cylindrical lining material above the inner surface of the iron cooling jacket, the use of copper as the lining material can be eliminated and the cooling jacket can be formed by a single iron material. However, it is easy to deform, easy to weld and machine, and easy to make and modify. In addition, since the cooling rate is practically low, the lubricity of the graphitic cylindrical lining material is sufficient, and the occurrence of flaws on the lining material does not pose a problem.
Description
【0001】[0001]
本考案は、固相芯材の周囲に外層材を形成する肉盛用の溶湯を連続的に注入し ながら、高周波誘導加熱によって溶着させる複合ロールの製造に際して使用する 肉盛用冷却モールドの構造に関する。 The present invention relates to the structure of a cooling mold for overlay welding, which is used when manufacturing a composite roll that is welded by high-frequency induction heating while continuously pouring a molten metal for overlaying which forms an outer layer material around a solid-phase core material. ..
【0002】[0002]
従来、この種の肉盛用冷却モールドの構造として、例えば特公昭52−284 6号公報に開示されたものがある。 Conventionally, as a structure of this type of buildup cooling mold, for example, there is one disclosed in Japanese Patent Publication No. 52-28646.
【0003】 このモールドの構造は、熱伝導率の低い鋼のような金属からなる冷却用のジャ ケットの内側面に熱伝導率の高い銅をライニングし、さらに、その上方部分を黒 鉛のような吸熱を所定レベルまで抑える冷却緩衝機能層を形成してなるものであ る。The structure of this mold is such that the inner surface of a cooling jacket made of metal such as steel having a low thermal conductivity is lined with copper having a high thermal conductivity, and the upper portion thereof is made of black lead. It is formed by forming a cooling buffer function layer that suppresses heat absorption to a predetermined level.
【0004】 これによって、肉盛用溶湯が凝固後に直接黒鉛層と接触することがないので黒 鉛ライニングに摺動疵が発生することがなく、また、下方の水冷ジャケット部分 で順次冷却凝固した肉盛層との摺動がスムーズになり損耗疵の発生は殆どないと されていた。As a result, since the molten metal for overlay welding does not come into direct contact with the graphite layer after solidification, sliding flaws do not occur in the black lead lining, and the meat that is successively cooled and solidified in the lower water cooling jacket portion. It was said that sliding with the piled layer became smooth and there was almost no occurrence of wear defects.
【0005】[0005]
ところが、この水冷ジャケット内面に銅材をライニングしたものでは、銅その ものの溶接性と加工性が悪く、製造と使用による変形修正の作業に手間を要し、 材料そのものも高価であるという欠点が指摘されていた。 However, the copper-lined inner surface of the water-cooled jacket has poor weldability and workability of the copper itself, which requires time and effort to correct deformation during manufacture and use, and the material itself is expensive. It had been.
【0006】 さらには、肉盛用溶湯の冷却モールド材としての必要な潤滑性の点から言えば 、モールドからの肉盛凝固体の引抜き速度が毎分5〜50mm程度に遅い本肉盛 りの方法においては、銅材よりも熱伝導性が悪い黒鉛材の方が好ましい。Further, in terms of lubricity required as a cooling mold material for the molten metal for overlay welding, in the case of the main overlay that the withdrawal speed of the overlay solidified body from the mold is about 5 to 50 mm per minute. In the method, a graphite material having a poor thermal conductivity is preferable to a copper material.
【0007】 本考案の目的は、かかる複合材の肉盛用冷却モールドから銅材の使用を無くし 黒鉛材の潤滑機能を発揮できるモールド構造を提供することにある。An object of the present invention is to provide a mold structure capable of exerting a lubricating function of a graphite material by eliminating the use of a copper material in such a composite overlay cooling mold.
【0008】[0008]
本考案の肉盛用冷却モールドは、鉄製の冷却ジャケットの内面上方に黒鉛質の 円筒状ライニング材を嵌合せしめてなることを特徴とする。 The overlay cooling mold of the present invention is characterized in that a graphite-made cylindrical lining material is fitted over the inner surface of an iron cooling jacket.
【0009】 上記黒鉛質の円筒状ライニング材は、溶湯凝固部分に形成されておれば良く、 円筒の長さが短い環状体であっても良い。The graphite cylindrical lining material may be formed in the molten metal solidification portion, and may be an annular body having a short cylinder length.
【0010】[0010]
冷却ジャケットが単一の鉄材によって形成されているので、構造が簡単、変形 しにくい、溶接、機械加工が容易で製作、修正を簡単に行うことができる。 Since the cooling jacket is made of a single iron material, it has a simple structure, is not easily deformed, is easy to weld and machine, and can be easily manufactured and modified.
【0011】 また、実用上は冷却速度が低いので黒鉛質の円筒状ライニング材による潤滑性 で十分でライニング材への疵の発生は問題にならない。Further, since the cooling rate is practically low, the lubricity of the graphite cylindrical lining material is sufficient, and the occurrence of flaws on the lining material does not pose a problem.

本考案に係る肉盛用冷却モールドを圧延用複合ロールの製造に適用した装置例 について説明する。 An example of an apparatus in which the cooling mold for overlay welding according to the present invention is applied to manufacture a composite roll for rolling will be described.
【0013】 図1は同装置の概要を断面によって示す図である。FIG. 1 is a sectional view showing an outline of the apparatus.
【0014】 同図において、1は芯材Aの予熱用コイルを示し、その下方には肉盛用金属溶 湯Bを収容する耐火材からなるタンディッシュ2が配置されている。3は同タン ディッシュ2を外方から加熱するための加熱コイルであり、4はこの加熱コイル 3による影響を遮断するための水冷式の遮蔽板を示す。本考案に係る鋳造モール ド5は上記タンディッシュ2と水冷式の遮蔽板4に連続して配置されている。同 鋳造モールド5は、冷却水導入口6と排出口7とを有する鉄製の環状水冷ジャケ ット8と、その内面上方に設けた段部9に嵌合して取付けられている黒鉛製の環 状ライニング材10からなる。In FIG. 1, reference numeral 1 denotes a coil for preheating the core material A, and a tundish 2 made of a refractory material for accommodating the metal melt B for overlaying is disposed below the coil. Reference numeral 3 is a heating coil for heating the tundish 2 from the outside, and reference numeral 4 is a water-cooling type shielding plate for blocking the influence of the heating coil 3. The casting mold 5 according to the present invention is arranged continuously with the tundish 2 and the water-cooled shield plate 4. The casting mold 5 comprises an iron annular water-cooling jacket 8 having a cooling water inlet 6 and an outlet 7, and a graphite ring fitted and attached to a step 9 provided above the inner surface thereof. The lining material 10 is used.
【0015】 黒鉛質の環状ライニング材10は、タンディッシュ2内の肉盛用溶湯Bが芯材 Aの引出し過程で徐々に冷却し芯材A上で凝固する凝固域に設けられており、か かる黒鉛質としては、熱伝導性と潤滑性を有するとともに、適度の強度を有する SiO2 を少量含有したものが特に好適に使用できる。The graphite annular lining material 10 is provided in a solidification region where the build-up molten metal B in the tundish 2 is gradually cooled and solidified on the core material A during the drawing process of the core material A. As such a graphite, one having a small amount of SiO 2 having thermal conductivity and lubricity and having an appropriate strength can be particularly preferably used.
【0016】 また、環状ライニング材10の嵌合箇所よりも下方のジャケット2の内面11 は、環状ライニング材10の内面より外方に形成されており、肉盛材Bとの間に ギャップgを設けている。Further, the inner surface 11 of the jacket 2 below the fitting portion of the annular lining material 10 is formed outside of the inner surface of the annular lining material 10, and a gap g is formed between it and the overlay material B. It is provided.
【0017】 このギャップgは、凝固直後のロール表面が潤滑能を有しない鉄製ジャケット 内面に焼付くことを防止する機能を有する。The gap g has a function of preventing the roll surface immediately after solidification from being seized on the inner surface of the iron jacket having no lubricating ability.

本考案によって以下の効果を奏することができる。 The present invention has the following effects.
【0019】 (1)構造自体が単一鉄材によるジャケットとそれに嵌合された黒鉛質円筒状ラ イニングとからなり単純であり、製造と修理のための補正が簡単である。(1) The structure itself is simple, consisting of a jacket made of a single iron material and a graphite cylindrical lining fitted to the jacket, and correction for manufacturing and repair is easy.
【0020】 (2)モールド自体の変形が少なく品質上も安定する。(2) The deformation of the mold itself is small and the quality is stable.
【0021】 (3)モールド内面は黒鉛質と鉄の単純な2層構造のため、それぞれの厚さを変 えることにより容易に冷却能を変更できる。(3) Since the inner surface of the mold has a simple two-layer structure of graphite and iron, the cooling ability can be easily changed by changing the thickness of each.
