一、前言宝钢钢锭模车间引进了新日铁用高呋喃树脂砂制造钢锭模的工艺,而当时国内还没有相应的糠醇含量达到90%的高呋喃尿醛树脂(以下简称高呋喃树脂)。为了在宝钢投产以后、使高呋喃树脂的供应能基于国内,在C 阶段谈判结束以后,我们就着手组织并委托有关科研单位,一起进行高呋喃树脂的研制和试验。经过几年努力,初步研制出一种高呋喃树脂,模索 I. Introduction Baosteel’s ingot mold workshop introduced the process of manufacturing high-furan resin sand for ingot molds by Nippon Steel. At the time, there was no corresponding high-furan urea-formaldehyde resin (hereinafter referred to as high furan resin) with a furfuryl alcohol content of 90%. In order to make high-furan resin supply available in China after Baosteel is put into production, after the conclusion of the C-phase negotiations, we started to organize and entrust relevant scientific research institutes to jointly research and test high-furan resins. After several years of hard work, initially developed a high-furan resin, modeling cable
