The basic link of hard driving of large blast furnace is to study the characteristics of gas dynamics in the furnace. The main problem is to improve the permeability of the burden and to control the distribution of the gas flow continuously. The fundamental solution of this problem lies upon investigations on sintering the overfine (-325 mesh) concentrates, screening off the fines, prospect of using 100% pellets and new requirement of coke quality in large blast furnace.

The basic link of hard driving of large blast furnace is to study the characteristics of gas dynamics in the furnace. The main problem is to improve the permeability of the burden and to control the distribution of the gas flow continuously. The fundamental solution of this problem lies upon investigations on sintering the overfine (-325 mesh) concentrates, screening off the fines, prospect of using 100% pellets and new requirement of coke quality in large blast furnace. The pressing necessities of employing high top pressure act at the same time as a powerful means of hard driving of the blast furnace. Thus, high top pressure promotes development of large blast furnace. The dimensions of throat gap for large blast furnaces have important effect on burden distribution. It is necessary to develop large diameter and low shaft furnace with more tuyeres of optimum small dimensions.

强化大型高炉生产的基本环节是研究炉内气体动力学特性.核心问题是要不断地改善炉料的透气性和控制煤气流的分布.问题的基本解决有赖于研究过细精矿(-325网目)的烧结,粉末的筛除,以及大型高炉使用100%球团的远景和对焦炭质置的新要求等.在大型高炉上采用高压操作的必要性和迫切性,同时也是强化大型高炉的有力手段.因此,高压促进高炉大型化的发展.大型化高炉炉喉间隙的大小,对布料有很大的影响.有必要发展矮胖、多风口、适当小风口的炉型.

This paper discusses the thin depth (0.03--0.05mm) gas carbonitiding process for thin wall of ferrule, in which friethanalamine liquid drops were fed into a reformed shaft furnace. The ferrules were carbonitrided at 800℃ for five minutes and then followed by oil quenching. After tempering at 180℃ for one hour, the surface hardness thus obtained is approximately Hv800. Since carbonitriding temperature is relatively low, the distotion of ferrule is very small with the change in diameter of ferrule less than...

This paper discusses the thin depth (0.03--0.05mm) gas carbonitiding process for thin wall of ferrule, in which friethanalamine liquid drops were fed into a reformed shaft furnace. The ferrules were carbonitrided at 800℃ for five minutes and then followed by oil quenching. After tempering at 180℃ for one hour, the surface hardness thus obtained is approximately Hv800. Since carbonitriding temperature is relatively low, the distotion of ferrule is very small with the change in diameter of ferrule less than 0.03 ram. After treatment, the ferrule is very tough with more austenite on its surface and less martensite in its core.

研究了卡套薄壁的薄层气体氰化工艺,使用三乙醇胺、滴入改装的井式炉中。炉子温度为800℃,氰化时间为5分钟,在180℃回火一小时后,卡套表面的硬度可大于Hv680,由于氰化的温度比较低,淬火速率低,所以卡套变形很小,其直径的变化不大于0.3mm。处理后卡套具有良好的韧性,这与它表面具有较多的残余奥氏体及心部具有较少的马氏体有关

During the reduction process in the shaft furnace, sulphur may move in different directions between the solid raw materials and the reducing gas. It is important to know the behavior of sulphur and methods of controlling it.

在竖炉直接还原过程中,硫在固相炉料与气相还原剂间能以不同方向发生转移。弄清硫在还原过程中的行为并掌握其控制方法,对于生产实践很有现实意义。通过热力学计算表明,原料中以FeS_2存在的硫在竖炉上部就会分解为FeS,释放出的硫以H_2S形式逸入气相。在竖炉还原带有海绵铁存在的区域,硫的走向则取决于反应H_2S(?)[S]+H_2进行的方向,并可通过调节入炉还原气成分H_2/H_2S(%)的比值加以控制。在热力学计算的基础上,提出了在还原过程开始前就能预测整个还原过程中硫走向的判别式,以便生产中预先选择合理的控制硫走向的工艺流程。文中还提出了控制海绵铁含硫量的方法。
