この発明はブルームタイプの連続鋳造用鋳型の製造方法
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a bloom type continuous casting mold.
一般にブルームタイプの連続鋳造用鋳型は銅または銅合
金製の二対の鋳型片から断面・矩形状の鋳型本体を組立
て、この本体の内壁面にニッケルなどの金属メッキ層を
形成することによって溶湯ないし凝固殻（こよる鋳型内
壁面の腐触ないし摩損を防ぐようにしている。In general, bloom type continuous casting molds are made by assembling a rectangular cross-sectional mold body from two pairs of mold pieces made of copper or copper alloy, and forming a metal plating layer of nickel or other metal on the inner wall of this body. This is to prevent corrosion or abrasion of the inner wall surface of the mold due to solidified shells.
従来、金属メッキ層の形成に際し、組立てられた鋳型本
体内に断面矩形状の不溶解性筒状ネットを同軸的に配設
してこのネット内一部ｔこニッケルの如き粒状の溶解性
陽極を装填し、上記本体内にメッキ液を供給する一方上
記本体を陰極として陰陽両極間に通電する電気メツキ法
が採用されている。Conventionally, when forming a metal plating layer, an insoluble cylindrical net with a rectangular cross section was placed coaxially within the assembled mold body, and a part of the net was filled with a granular soluble anode such as nickel. An electroplating method is employed in which the main body is loaded and a plating solution is supplied into the main body, while the main body is used as a cathode and current is applied between the negative and positive electrodes.
ところがこの電気メツキ法により形成される金属メッキ
層は鋳型本体内壁面のコーナ一部がコーナ一部以外の平
面部に較べて著るしく薄くなる傾向があった。However, the metal plating layer formed by this electroplating method tends to be significantly thinner at the corner portions of the wall surface within the mold body than at the flat portions other than the corner portions.
たとえば平面部がＬｍｍ程度にされた場合コーナ一部は
約０．３ ｍｍ以下の厚みしか得られない。For example, if the flat portion is approximately L mm thick, the corner portion will only have a thickness of approximately 0.3 mm or less.
このためコーナ一部からの鋳型の腐触ないし摩損がおこ
り鋳型の寿命が短かくなるとともに鋳片にブレークアウ
トが発生するなどの欠陥を招いていた。As a result, corrosion or abrasion of the mold from a portion of the corner occurs, shortening the life of the mold and causing defects such as breakouts in the slab.
また粒状陽極がニッケルの場合ニッケルメッキ層にピン
ホールないしブツが発生してメッキ層全体の耐腐触性、
耐摩耗性などに劣る問題もあった。In addition, if the granular anode is nickel, pinholes or bumps may occur in the nickel plating layer, reducing the corrosion resistance of the entire plating layer.
There were also problems with poor wear resistance.
この発明者らは、かかる金属メッキ層の厚み変化が主に
陽極の形状に基づくコーナ一部と平面部とにおける電流
密度の差異に起因し、また粒状ニッケル陽極がメッキ液

一な電流密度が得られかつメッキ液によってスラッジを
形成することのない陽極を探究することによって、前記
問題を解決するべく鋭意検討した結果、この発明を完成
するに至ったものである。The inventors discovered that this change in the thickness of the metal plating layer is mainly due to the difference in current density between the corner part and the flat part based on the shape of the anode. Based on the idea that the sludge becomes a sludge made up of materials and adheres to the plating layer and causes pinholes, it is possible to obtain a uniform current density in some corners and flat areas, and to remove the sludge from the plating solution. The present invention was completed as a result of intensive study to solve the above problem by searching for an anode that does not form.
以下この発明法を図面に基づいて説明する。This invention method will be explained below based on the drawings.
