Purpose of the development: For desulphurization.

Recommended application field: Metallurgical industry.

Advantages over analogues: The technical solution for the invention in comparison with similar dosing regimens provides stable and injecting molten magnesium in the iron. This ensures stability of the parameters of injection of the reagent, which in turn permits the refuse supporting and magnesium impurities to practically solve the problem of deep refining of pig iron by the sulfur content.

The development stage readiness: Introduced in production

Technical and economic effect: Using Position patent allows to profit from the desulphurization in the amount of 2,685 million dollars / year. The payback period for the installation of desulphurization of 2.5 million tons for the year is 10 months. Besides this economic effect UDCH patent ensures the implementation of resource desulphurization technology through: - Reduce the cost of pig iron with slag; - Reducing the cost of the reagent; - Reducing the cost of waste slag; - Reduction of capital costs during construction UDCH due to the smaller volume of the equipment.

Description of the development:
()
A group of scientists from the Institute of Ferrous Metallurgy. ZI Nekrasov National Academy of Sciences of Ukraine made an invention that is protected by patent number 67533 Ukraine A. Installing desulphurization (UDCH) grainy magnesium in heavy buckets є modern automated complex secondary treatment with a production capacity of 0.5 to 5.0 million tons / year of iron sulfur content to 0.001-0.002%. High technical achievement results by injection administration of magnesium iron using technical devices patent. Installing patent permits provide stable reagent introduction in cast iron, cast iron bath barboturivaniya uniform, reduces the load on the elements of plant design, process control and simplifies maintenance of the lances. At the same time reducing capital costs, it is possible to fill the buckets 95-97% iron and a high absorption agent (90%). As of 2005 consumers use technology desulphurization magnesium patent has JSC "MK" Iron & Steel Works "," Zaporizhstal "," Kryvorizhstal "Enakiyevo Steel, 24 installation on steel mills in China joint production volume of 28 million tons of pig iron per year . Potential customers who have sent a request for installation is: - India (1.5 million tons / year) - Iran (0.8 million tons / year) - Poland (5.4 million tons / year) - Bulgaria (1.0 million tons / year). Technology exhibited at international exhibitions in India, China and Germany. The invention won the All-Ukrainian competition "The Invention of 2005."
