| | This article summarizes the development of submerged nozzles for continuous casting of steel in China. It introduces the processes of manufacture, properties of products and results of using submerged nozzles made of graphite corundum material or ceramically fused silica. The author also gives the existing problems and the future trends of development. Finally, some proposals for further research work are presented. | | 本文总结了我国连铸用浸入式长水口的发展过程,着重介绍了熔融石英质和铝碳质浸入式水口的工艺研究,产品性能,使用效果,存在问题及今后努力方向.最后,为今后的研究工作提出建议. | | 文摘来源 | | This paper describes following results in laboratory. | | 本文叙述了如下研究结果: 1.光谱分析表明,中和絮凝沉淀污泥主要由锌、钙、铁、镁、铝、碳等组成,其它元素含量甚微,污泥经盐酸反应,过滤及去杂质等程序处理,可得浓度为30°Be′左右的较纯净的氯化锌回收液,用它来浸渍木屑,可得良好质量的产品。研究也同时表明,废水处理及污泥回收的成本不仅完全可由回收的氯化锌加以弥补,且尚有盈余。 2.排放水经离子交换或其它方法去钙处理,可得极纯净的处理水,并可循环作洗炭之用。 | | 文摘来源 | | This paper is concerned with the industriaI experiment of ladle injection using the assemblinglances made of high alumina-graphite material.It was shown that these lances have excellent re-sistance to thermal shock and slag erosion. | | 本文介绍研制的铝碳质组装喷枪在117炉钢包喷粉的工业试验情况。组装喷枪显示出优良的抗热震性能和抗渣浸蚀性能以及良好的使用效果,达到国内外先进水平并有显著的经济效益。研制成功组装喷枪为国内发展喷枪开辟了新途径。适应国内钢包喷粉发展的需要。 | | 文摘来源 | |   | | << 更多相关文摘 |
