· Blast refers to the combustion air being "forced" or supplied above atmospheric pressure. The components of a blast furnace include the Charge, exhaust gas outlet, charging bells, gas outlet, tuyeres, taphole, bustle pipe, slag hole, refractory lining, and conveyor system.
blastfurnace slag is rapidly chilled, as by immersion in water. It is a nonmetallic product, consisting of silies and aluminosilies of calcium and other bases, developed in a molten condition simultaneously with iron in a blast furnace. It is used as a cementitious material in Portland cement concrete. GGBFS was first used in lime mortar production as early as the 1700's. In Germany ...

A central part of this zero waste strategy is to utilize and recycle the byproducts of steel production. Blast furnace and steel slags, sludges and dusts are either used internally or processed so that they can be reused. This not only saves valuable resources but also significantly reduces climateharmful CO2 emissions. Slags in hot demand. Liquid blast furnace slag is processed into ground ...
· 1. Blast furnace ironmaking is inseparable from the coke source, but the coke resources are getting less and less, but the price is getting higher and higher, the cost of iron making will be higher and higher, and it is likely that one day will meet the depletion of coke resources. 2. The blast furnace ironmaking damages the environment very much.
In response to exponential market demand, the annual production capacity at the ArcelorMittal site in FossurMer, France, is due to rise from to million tons of steel. One of the key projects designed to help meet this objective was the refurbishment of blast furnace no 1. The preservation of the colossal piece of production equipment ...

As a byproduct of existing industrial processes, GGBS is even more sustainable than many other cement substitutes such as fly ash. Our products conform to BS EN 151671. This is the British standard for the use of Ground Granulated Blast furnace Slag in concrete, mortar and grout. GGBS counts fully towards the cement content of concrete mixes.
· The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th Century and produced one ton per day. Blast furnace equipment is in continuous evolution and modern, giant furnaces produce 13,000 tons per day. Even though equipment is improved and higher production rates can be achieved, the ...

· In a blast furnace (BF) the iron oxides are reduced and the resulting iron is melted. Approximately 70% of the global steel production involves the use of BFs. Sizes of BFs installed cover a very wide spectrum, ranging from less than 100 m3 to more than 5000 m3. Larger BFs have less heat losses and enable installation of heat recovery equipment more cost effectively.
Fig. 1 Production flow of the blast furnace slag. NIPPON STEEL SUMITOMO METAL TECHNICAL REPORT No. 109 JULY Nippon Steel Sumitomo Metal Corporation sold million t of blast furnace slag aggregate (including inhouse use) annually in the first half of the 2000s, but due to the latest fall in the demand for concrete aggregate (264 million t in 2011 2)), the sale fell to below 1 ...
Ground granulated blast furnace slag is molten slag—a byproduct of the blast furnace ironmaking process—which is watercooled rapidly, dried, and ground. When blast furnace slag is cooled rapidly, it becomes almost vitreous. It has a latent hydraulic property,, it hardens when stimulated by an alkali. Blast furnace slag cement is a mixture of ground granulated blast furnace ...
