团矿

It analyses the application of cold briquetted ore in ferromanganese blast furnace and the technical measures adopted by Xinyang Steel Company Ferroalloys Branch.

介绍了信阳钢铁公司铁合金厂锰铁高炉配用冷压球团矿的生产实验和采取的技术操作措施，并分析了在生产应用中所产生的综合效益。

According to the technological principle, the process flow of pellet production is designed and technical demands for raw materials are determined. Test and application results show that developed Ti-content pellets have characteristics of high strength, high grade of iron and low cost and play double roles in blast furnace lining protection and reducing the cost of furnace charge material.

根据球团生产工艺原理，设计了生产球团的工艺流程并确定了技术要求，试验及使用结果表明，研制生产的含钛球团矿具有强度高、含铁品位高，成本低等特点，起到了高炉护炉及降低炉料成本的双重作用。

The results show that the viscosity of primary slag can be increased by more than two times when unburnt coal is entrapped in the slag and increasing pellet ratio is favorable to the improvement of the fluidity of primary slag and the reduction of primary slag.

结果表明，初渣中混入未燃煤粉可使初渣的黏度增大2倍以上，提高球团矿配比对改善初渣流动性和减少初渣量有利。

The Change of hot strength of iron ore pellets during oxidizing roasting and reduction was researched.

研究了球团矿在氧化焙烧和还原过程中抗压强度的变化规律。

In order to supply technical data of fluxed pellets production for SHOUGANG, the influences of temperature, time and basicity on characteristics of preheated and indurated pellet have been studied in laborator

为给首钢生产熔剂性球团矿提供依据，在试验室条件下研究了温度、时间、球团碱度等对熔剂性球团理化及冶金性能影响的规

Meanwhile, the firing system could be adjusted sensitively and flexibly. The"heat inertia"of this device is reduced distinctly and the pellet in it could be indurated smoothly and even.

在研究分析了现有球团矿焙烧实验装置的&温度滞后&与&热惯性&的产生原因之后，作者设计了一套新的焙烧实验装置。

A integrated mathematical model was established in accordance with the process of metallurgical production and it was composed of the process models and the raw materials distribution models. The process models include the sintering process model, the pelleting process model and the iron making process model.

数学模型分为6个子模型，其中工艺模型有烧结机优化模型、竖炉优化模型、高炉优化模型，物料配置模型有铁精粉优化配置模型，烧结矿优化配置模型和球团矿优化配置模型，模型之间交互的数据流为原料或产品的物料流量、物料性能、价格及原料性能的影子价格。

Its product quality will obtain top-ranking technique standard of pellets in the world.

其产品质量达到了世界一流球团矿的技术标准。

And the other is arc Process using pre-reduction pellets or high-quality industrial scrap as raw materials.

当前，主要有二种炼钢工艺，较为普遍的是以高炉铁水和废钢为原料的转炉炼钢工艺，其次是以预还原球团矿或高质量的工业废钢为原料的电弧工艺。

The blast furnace of direct combustion is used to provide heat for drying concentrates in rotary kiln.

直燃式煤粉热风炉是球团矿生产中为精矿粉干燥回转窑提供热源的燃烧炉。

The visit of all these marauders must be anticipated, and measures taken to prevent their depredation .

应该预料到这些抢劫者的侵袭，并制定防范他们抢劫的措施。

It is no effect of him whatever threaten or speak the sense.

无论是恐吓还是讲道理对他都不起作用。
