technology all have shown progress. In 2005, Botou Tian- lida Machinery Co. Ltd., Hebei, China, produced an FMC gantry grinder part weighing 42 tons. In 2009, Botou East Construction Casting Co. Ltd., Hebei, China, produced an FMC machine tool bed component weighing 75 tons. Botou Qingfeng Machinery Co. Ltd., Hebei, China, has produced parts weighing 10, 13.8 and 18 tons and another weighing 84 tons.
Expendable Pattern Casting Equipment and Production
Te special equipment required for EPC is divided into
two major categories: 1. Pattern manufacturing (white side): pre-foaming
machines, pattern machines, pattern-bonding machines and coating-drying rooms. 2. Molding and pouring (black side): vibration tables,
vacuum systems, sand handling systems, sand box conveyers and sand cooling systems. With assistance from the FMC branch of the China
Foundry Association, the Hangzhou Fuyang Jiangnan Light Industry Packaging Machinery Factory, Hang- zhou, China, successfully developed the third generation of break-style pre-foaming machines in 2000. In 2005, more accurate PLC-controlled automatic break-style pre-foaming machines were developed. Te company has
③ 实型铸造和消失模铸对技术和生产同步快速发展。 (4)从2007年开始,实型/消失模铸造发展整体水平全 面提高,向赶超国外水平方向发展,主要表现如下: ① 从原辅材料、模具制造、模样制造设备、黑区,到铸 造工艺技术等,各领域均有较大进步,正向技术成熟 和接近赶超国外的水平方向发展。
② 2009年实型铸件/消失模铸件产量76万t,大大超美 国和日本的产量总和,成为世界第一。 ③ 在实型/消失模铸造大件方面有了新突破。2005年泊头 天利达机械有限公司成功生产了重42t的龙门磨床床身 实型铸件,2009年泊头东建铸造有限公司成功生产重 75吨的机床机座实型铸件。泊头青峰机械有限公司采用 消失模铸造技术,于2008年成功生产了重达10t,2009 年13.8t,2010年18.t的消失模铸件。到2011年,泊头 青峰机械有限公司成功生产重20t的消失模铸件;泊头 东建铸造有限公司成功生产重84t实型铸件。
3 消失模铸造及其专用设备和生产线
消失模铸造专用设备主要分为二大类:(1)模样制造 (白区):预发泡机、成型机、模样粘接机、模样涂料 干燥室等。(2)铸件造型浇注(黑区):振动台、负压 系统、砂处理系统、砂箱输送系统、砂冷却系统等。
In 2007, the output of the lost foam casting process was 648,000 tons, with 266,000 tons produced via FMC and 372,000 tons made through EPC. In 2009, China produced 760,000 tons of lost foam castings (333,000 tons of FMC and 427,000 tons of EPC).
1995年前,实型铸件/消失模铸件产量很少,全国只有数千吨; 经过十几年的发展,特别是近5年发展迅速;从2005年开始成 倍增长,到2007年实型铸件/消失模铸件的产量超过美国成为世 界第一。
