矿石

This thesis applies factor analysis in ship type optimization and uses this method to comprehensively grade the alternative ship types of second Carriage iron ore shipment from Majishan to Bao steel and finally gets the optimal ship type for this line.

本论文主要内容包括：第二章主要分析了国际铁矿石运输现状；第三章介绍我国进口铁矿石的情况，分析了我们铁矿石运输存在的不足并预测了发展趋势；第四章介绍了传统的船型论证方法、步骤；第五章计算了从马迹山到宝钢原料码头的船型方案的主要指标，并用传统的方法做了船型方案的选优；第六章介绍了因子分析法在船型论证中的应用，并用因子分析法对船型选优做了综合评定，得出适合马迹山到宝钢的二程矿石运输的最优船型。

Bucket elevator The machine has the advantages of big conveying capacity, high hoisting height, stable and reliable running and long working life. Its performance and parameter accord with JB3926?85 'Vertical Bucket Elevator', which consults the international standard and advanced foreign standard and the towing circle chain accords with MT36?80 'High-Strength Circle Chain for Mine'. The machine is applicable for conveying the power, grain and block materials, such as coal, cement, block, sand, clay and ore. The bucket elevator is allowed to convey materials with high temperature with the special circle chain structure.

联系人：刘永刚该类提升设备具有输送量大，提升高度高，运行平稳可靠，寿命长显著优点，其主要性能及参数符合JB3926----85《垂直斗式提升机》（该标准等效参照了国际标准和国外先进标准），牵引圆环链符合MT36----80《矿用高强度圆环链》，本提升机适于输送粉状，粒状及小块状的无磨琢性及磨琢性小的物料，如：煤、水泥、石块、砂、粘土、矿石等，由于提升机的牵引机构是环行链条，因此允许输送温度较高的材料。
