Abstract: Ingot mold for forging rolling composite is a kind of ingot mold with. high efficiency, low cost and wide application. Based on the experience of ingot production at factory and the design principle of ingot mold, the parameters such as ingot taper, aspect ratio, cap volume ratio and ingot mold thickness are designed, and a 5. 5 ~7 t ingot mold for forging and rolling composite is developed. The production practice shows that the ingot mold with design parameters of 3. 8% ta¬per, 2. 0 ~ 2. 5 height-width ratio ( adjustable cap opening) , 12. 5% cap-volume ratio, upper thin and lower thick wall thickness (upper 150 mm, lower 175 mm) has obvious effect on improving ingot quality and the forging yield increases from original 83. 0% to 85. 0%.

摘要： 锻轧复合用钢锭模是一种高效率、低成本、用途广的钢锭模,基于钢厂大量方锭生产经验并依据钢锭模设计原理对钢锭锥度、高宽比、帽容比、锭模厚度等参数进行设计,开发了锻轧复合用5.5～7 t方锭钢锭模。生产实践表明,采用设计参数为3.8%锥度、2.0～2.5高宽比(可调节式帽口)、12.5%帽容比、上薄下厚式壁厚(上部150mm,下部175mm)的钢锭模,钢锭质量提升效果明显,锻造成材率由原83.0%提高到85.0%。
