Achieve uniform sinter quality at low operational costs. Sinter is the primary feed material for making iron in a blast furnace. The production of high-quality sinter is crucial for assuring consistent, stable furnace productivity with a low consumption of reductants. Sinter quality begins with the proper selection and mixing of the raw materials.
Evaluation of Sinter Quality for Improvement in Gas .

2. The lead blast furnace has in the past been at its most productive when treating lead sinter, but this does not mean that a possible demise of lead sinter plants will inevitably leave the lead blast furnace stranded. The use of blast furnaces in the secondary lead
Measurements of the composition of the condensed phases derived from the sinter feed to a commercial lead blast furnace are presented. No significant reaction was detected at a level in the furnace above about 3 m from the tuyeres, at which the measured temperature was about 800 °C. The reaction zone was predominantly in a region 1 m to 2 m above the tuyeres accompanied by fusion and phase ...
mud, increasing its contents in the sinter charge mixture leads to reduced speed of the sintering process, which consequently affects the productivity at the blast furnace yard. The sinter produced with the addition of 3% red mud shows the highest reducibility. These results indicate the suitability of recycling RM in the Egyptian iron ore
Key words: lead slag, lead sinter, lead blast furnace, reduction kinetics and mechanisms 1 . INTRODUCTION The lead blast furnace is still the predominant technology used in the production of primary lead metal [1]. For most operations the feed to the furnace is in the form of oxidized lead sinter produced from lead sulphide concentrates.
06-02-2013· 1.2. Why sintering. Lead and zin metals are produced in blast furnace. In a blast furnace, ore, coke and flux are continuously supplied through the top of the furnace, while air (sometimes with oxygen enrichment) is blown into the lower section of the furnace, so that the chemical reactions take place throughout the furnace as the material moves downward.
The major target is the treatment of sintering offgases. It will be reached in the near future due to specific investments. The most difficult target is the treatment of the lead blast furnace offgases. As the SO 2 level is very low, a specific process has to be developed.
12-03-2015· The first sinter strand in the steel industry with suction area of 8 m3 was put into operation at Birdsboro, Pennsylvania (USA) in 1911.Some important quality requirements of sinter are – high resistance against mechanical stress under blast furnace reduction conditions, good reducibility, high Fe content, low softening melting range and uniformity of the size distribution.
Sinter making is a method of fusing iron ore fines into larger particles suitable for charging into the blast furnace.Predominant source of iron in many blast furnace processes.This technology was developed for the treatment of the waste fines in the early 20th century.Since then sinter has.
TSL and blast furnace operations. The top submerged lance (TSL) and blast furnace operations are the actual smelting part of the process and involve the high temperature reduction of sinter with metallurgical coke to produce a crude lead bullion and slag. Lead bullion contains small amounts of other metals including silver doré, gold and copper.
