Abstract
Спосіб виробництва офлюсованого огрудкованого залізовмісного матеріалу з підвищеним вмістом заліза і залишкового вуглецю включає отримання металізованих обкотишів або металізованих руд, твердого палива та сирих обкотишів з низькою температурою плавлення, наступним їх змішуванням і термообробкою. Металізовані обкотиші або руди зі ступенем металізації 5-95 % розміром 10-20 мм кількістю 50-80 %, тверде паливо розміром 0-12 мм кількістю 15-3 % і сирі офлюсовані вапняком обкотиші крупністю 8-14 мм з шихти з низькою температурою плавлення кількістю 35-17 % змішуються, після чого суміш матеріалів піддається термообробці, що включає сушку, нагрівання, випал і охолодження продукту з наступними температурами при подачі газоподібного теплоносія в зони термообробки: сушка - 350-450 °C, нагрівання - 600-1100 °C, випалу - 1200-1300 °C і охолодження - 10-30 °C.A method of producing an offset iron-coated iron-containing material with a high content of iron and residual carbon involves the production of metallized pellets or metallized ores, solid fuels and crude pellets with a low melting point, subsequent mixing and heat treatment. Metallized pellets or ores with a degree of metallization of 5-95% 10-20 mm in size 50-80%, solid fuel in the size of 0-12 mm in the amount of 15-3% and crude offlime limestone in the size of 8-14 mm from a mixture with low melting point the amount of 35-17% are mixed, after which the mixture of materials is subjected to heat treatment, including drying, heating, firing and cooling of the product with the following temperatures when the supply of gaseous coolant in the zone of heat treatment: drying - 350-450 ° C, heating - 600-1100 ° C , firing - 1200-1300 ° C and cooling - 10-30 ° C.
