摘要:800MN 油压机的上板梁单体净重 233 吨,板厚 1025 mm,为目前国内外大型铸钢中板厚最大的铸钢
件之一,技术要求高,实际铸造生产难度极大。经过对其工艺技术的分析,制定针对性的工艺措施,同时
利用计算机凝固模拟技术进行了验证与完善,成功铸造了 800MN 油压机上板梁。

Abstract: At present, the upper plate beam of 800MN oil hydraulic press was one of the most massiness steel
castings in the world, weight was 233Ton and thickness was up to 1025 mm. The casting was very
diffuclty due to its more high technical demand. According to the technology analysis of the upper plate beam, the
pertinence technology measure was made and its accureness was validated and perfected puter concreting
simulation. The upper plate beam was essfully casted at last.
Key words: Upper Plate Beam; Steel Casting for Thick Plate; Concreting Simulation; Foundry Technology
中国二重设计的 800MN 油压机是目前国内最大的模锻油压机。马鞍山钢铁股份有限公司重型机械设备
制造公司承制了 800MN 油压机的主体设备――上横梁,由两件上板梁组装而成。由于上板梁为超厚型板类
铸钢件,铸件模数高达 350mm,净重 233 吨,也是目前板类铸件之一[1],
而且其质量要求较高,超声波探伤需达到德国 DIN 标准 2 级,因此上板梁的毛坯制作难度极大。
