攀枝花学院本科毕业设计（论文） 摘要 攀枝花学院本科毕业设计（论文） 年产200万吨钢的转炉炼钢车间设计 ——钢包设计 摘 要 根据年产200万吨钢转炉车间设计的要求和国家相关政策的规定，确定转炉的大小为220吨，进一步得到了符合实际生产的与之匹配的钢包容量大小为250吨，通过计算确定钢包上部内径和高度均为4289mm，生产过程中所需要的钢包的数量为11个。对钢包用耐火材料进行了设计，分为2套钢包即浇注钢包和砌筑钢包。分别对其进行分析确定了他们的绝热层和工作层的设计方法，对于浇注钢包采用整体浇注和或剥皮浇注，对砌筑钢包采用综合砌筑的方案；通过对钢包透气砖和滑动水口系统耐火材料的外形设计，确定了透气砖系统耐火材料的尺寸和滑动水口系统耐火材料的尺寸；最后根据钢包用耐火材料的使用要求，针对不同钢种和不同部位的不同要求以及耐火材料的理化性能指标，对钢包所用的耐火材料进行了优化选择。 关键词 炼钢，钢包，砌筑，浇注，耐火材料 攀枝花学院本科毕业设计（论文） ABSTRACT ABSTRACT According to the annual output of 2 million tons of steel converter workshop design requirements and relevant national policies and regulations, determine the size of the converter is 220 tons, has been further conform to the actual production of matching the ladle size capacity of 250 tons, through the calculate and determine the ladle upper inner diameter and height is 4289 mm, the production process required the number of ladles for 11. Ladle refractory materials used for the design, divided into 2 sets of ladle pouring ladle and laying the ladle. Respectively to analyze it to determine their thermal barrier and layer, the design method of the work for adopts the integral casting and or peeling pouring ladle cover in casting, for the composite masonry methods in laying the ladle; Through the vent brick of ladle refractory and slide gate system design, determine the size of the system of gas supply brick and refractory materials and refractory materials the size of the slide gate system; Finally according to the requirements of the ladle refractory material used, according to different steel grade and the different requirements of different parts and the rational index of the refractory, the ladle refractory material used in the optimized choice.
