PRODUCTION OF MAGNESIA-CARBON BRICK

摘要

PURPOSE:To produce a magnesia.carbon brick using a novolak type phenolic resin mixable and moldable at normal temperature as a binder without requiring an aging period after kneading. CONSTITUTION:A compound comprising magnesia raw material, a carbonaceous raw material and a metal powder raw material is kneaded with a liquid mixture of a resol type phenol resin and a novolak type phenol resin in a blending ratio of 5/95 to 15/85 as an organic binder to give body, which is molded at normal temperature while reducing pressure.
