Title (EN) RESIN-COATED SAND FOR USE IN CAST STEEL, CASTING MOLD MADE OF THE SAND, STEEL CASTING CASTED USING THE CASTING MOLD
(FR) SABLE ENDUIT DE RESINE POUR UNE UTILISATION POUR DE L'ACIER COULE, MOULE FABRIQUE A PARTIR DE CE SABLE, ET MOULAGE D'ACIER MOULE EN UTILISANT CE MOULE
(JA) 鋳鋼用レジンコーテッドサンド、同サンドからなる鋳型および同鋳型により鋳造された鋼鋳物
Abstract:
(EN) A resin-coated san for use in cast steel, comprising a casting sand, a phenolic resin in an amount of 2.5 to 5.0% by weight relative to the amount of the casting sand, potassium nitrate and vinsole. A steel casting manufactured by the casting on a casting mold which is molded using the resin-coated sand can effectively prevent the occurrence of hot-cracking or bath wrinkle even in a thin and large-sized article.
(FR) L'invention concerne un sable enduit de résine pour une utilisation pour de l'acier coulé, comprenant un sable de moulage, une résine phénolique en quantité comprise entre 2,5 et 5,0 % en poids par rapport à la quantité de sable de moulage, du nitrate de potassium, et du vinsole. L'invention concerne également un moulage en acier obtenu par coulage dans un moule fabriqué à partir du sable enduit de résine, ce procédé permettant de prévenir efficacement les cassures à chaud ou les rides à la surface du bain, même pour un article fin et de grande taille.
(JA)  本発明の鋳鋼用のレジンコーテッドサンドは、鋳物砂と、同鋳物砂に対する2.5~5.0重量%のフェノール系樹脂と、硝酸カリウムと、ビンゾールとを含んでいることを特徴としている。この鋳鋼用レジンコーテッドサンドを用いて造型された鋳型により鋳造された鋼鋳物は薄肉で大型のものであっても、熱間亀裂と湯じわの発生が効果的に防げる。
