Currently,approx.95% of steel are produced by means of continuous casting,and the trend is rising,commonly using continuous slab casters and CSP(E) plants.In the field of conventional continuous casting there are two major trends.In Europe,production has been focusing on higher quality grades.Here,the material of the slabs is at the center of attention,e.g.higher-strength and other quality steel grades.In Asia,on the other hand,there is a trend towards increased output volumes and therefore higher casting speeds.These two trends result in very different requirements placed on the casters.This publication deals with “High Speed Casting” for continuous slab casters,which means conventional slab casting with high casting speeds.For this,construction details have to be considered as well as the metallurgical conditions.Tried and tested measures,for example electromagnetic brakes and stirrers,are assessed with regard to their influence on high speed casting.New developments such as the HD mold and the STEC-Roll(R) are explained and examined with regard to their use in high speed casting plants.By example of selected reference plants,the effectiveness of the technologies developed by SMS Siemag is proven.Based on these new developments and the well-proven technical expertise,a High Speed Casting 3.0 continuous slab caster is designed,with a casting speed of up to 3.0 m/min.

本文先利用原位分析技术中的线扫描得到连铸方坯内部在中心线位置、V形负偏析带以及CET区域这三个位置沿拉坯方向的碳元素分布.由于碳元素沿拉坯方向的分布是随着时间而不断形成的,因此可将其处理为三组时间序列.在此基础上,利用乘积季节模型等经典时间序列分析技术对这三组时间序列进行了分析,并得出中心线位置处所对应的时间序列具有一定的周期性特征.同时还发现在沿拉坯方向的同一个位置点,中心线位置处碳元素含量与C
对国外某钛粗精矿进行了工艺矿物学研究,查明了矿石中有用元素赋存状态、矿物组成和嵌布粒度等特性,并进行了电选试验研究.试验结果表明,在给矿钛品位为34％左右时,通过全粒级选别时分选指标为:钛精矿TiO2品位48.19％,回收率88.10％;分级选别时分选指标为:钛精矿TiO2 品位48.90％,回收率90.14％.实验室试验研究结果为后续的工程设计提供了较为合理的工艺流程.
