本义探讨了球铁钢锭模在使用过程中变形卡锭的原因,对两种锭模的实验模型进行温度和应力的测试结果表明:具有曲面设计特点的实验模型有效地改善了其高温区的应力分布状态。根据模拟实验结果,设计了具有曲面的球铁钢锭模,使钢锭模消耗从原来的18.62 kg/t下降到6.50 kg/t,钢锭模平均使用次数从原来的54.59次提高到137.8次。鞍山钢铁公司在一种锭型上推广应用该技术,年获经济效益达350万元以上。
The original meaning of this paper discusses the reason of the deformation of the ductile iron ingot mold during use, and the test results of the temperature and the stress of the two ingot molds show that the experimental model with the surface design features effectively improves the stress in the high temperature zone Distribution status. According to the results of simulation, a ductile iron ingot mold with curved surface was designed to reduce the ingot die consumption from 18.62 kg / t to 6.50 kg / t. The average number of ingot molds increased from 54.59 times to 137.8 times. Anshan Iron and Steel Company to promote the use of this technology in a ingot, the economic benefit of up to 3.5 million yuan.
