1999年2月12日,国家重点工程宁波宝新不锈钢有限公司还在进行不锈钢薄板轧钢试生产,其主要生产设备主轧机是从日本大名鼎鼎的“三菱重工”引进的,价值2.1亿元人民币。 为了保护这组价格昂贵的主轧机,公司分别为它安装了两套自动灭火系统:一套是由德国Total Walther公司生产的低压二氧化碳灭火系统,另一套是由杭州新纪元消防科技有限公司设计制造并安装的高压二氧化碳灭火系统;以前套系统为主,后套主要作应急备用。 这天上午9时40分,主轧机在进行不锈钢薄板生产时,突然钢板跑偏移位,与导向棍发生剧烈磨擦,磨擦所产生的热量引燃了主轧机组内部的轧制油。由于机组内外、底部沟槽表面都散发着油层和油雾,火势蔓延非常迅速。仅数秒钟时间,整个机组底部已是一片火海,浓烟烈
On February 12, 1999, Ningbo Baoxin Stainless Steel Co., Ltd., a state key project, is still conducting trial production of stainless steel sheet rolling. The main production equipment of the main mill is imported from Japan’s famous Mitsubishi Heavy Industries with a value of 210 million yuan. In order to protect this group of expensive main rolling mills, the company installed two automatic fire extinguishing systems for each of them: a low-pressure carbon dioxide fire extinguishing system manufactured by Total Walther in Germany and a third designed and manufactured by Hangzhou New Era Firefighting Technology Co., Ltd. And installed high-pressure carbon dioxide fire extinguishing system; the former system-based, after the main set for emergency backup. At 9:40 a.m. this morning, when the main mill was producing stainless steel sheets, the steel suddenly ran out of position and drastically collided with the guide bar. The heat generated by friction ignited the rolling oil in the main rolling mill. As the inside and outside the unit, the bottom of the groove surface are exuded oil layer and oil mist, the fire spread very quickly. Only a few seconds, the entire bottom of the unit is a sea of flames, strong smoke
