(54) СПОСОБ ПОЛУЧЕНИЯ ФОРМОВАННОГО КОКСА(54) METHOD OF OBTAINING A FORMED COKE
1one
Изобретение относитс к способам получени формо,за«.ного .кокса.The invention relates to methods for producing a form, for coke.
Получаемый кокс может быть использоваН в качест1ве бездымного топлива, дл ферросплавного производства, химической лромышленйости и других отраслей народного хоз йства , а также дл доменного процесса.The resulting coke can be used as a smokeless fuel, for ferroalloy production, the chemical industry and other branches of the national economy, as well as for the blast furnace process.
Известны CnoCOi6bi получени .кокса: основанный на прокадке Т1верды1М теплолосителем брикетов из Смеси лредварительно нагретого до пластического состо ни хорошо спекающегос угл (30%) н полукокса, полученного при полукоксовании (-70%) слабоопекающегос угл 1.Known CnoCOi6bi coke production: based on T1-hardened baking, a heat exchanger of briquettes from a mixture of previously well-squeezed coal (30%) n semi-coke, which was obtained by semi-coking (-70%) of weakly coking coal 1).
Недостатком этого метода вл етс необходимОСть осуществл ть -предварительное полукоксование 70% iBicero сырь , что требует больших капиталовложений и экюплуатацнонных расходов дл строительства цехов полукоксовани , а также необходимость строительства сооружений дл нашрева спекающегос угл и специальных устрОЙств дл смешиеаеи Пластичного угл с полукоксом. Поэтому метод вл етс весьма .сложным и дорогим.The disadvantage of this method is that it is necessary to carry out -preliminary semi-coking of 70% of iBicero raw materials, which requires large capital investments and cost-effective expenditures for the construction of semi-coking shops, as well as the need to construct structures for coal sintering coal and special devices for adjacent Coal Coal. Therefore, the method is very complicated and expensive.
Известен .опособ получени формованного бездымного кокса, основанный «а предварительном брикетировании углей со св зующи ми 1веществами с последующей термической обработкой брикетов 2.A known method of producing molded smokeless coke, based on the pre-briquetting of coal with binding substances, followed by heat treatment of the briquettes 2.
Этот метод также имеет недостатки, которые заключаютс .в необходимости расходовани значительных количеств св зующего, которые дефицитны и «е безвредны дл здоровь , а также в необходимости значительных затрат на оборудование, эксплуатацию узла смешенИЯ угл и св зующего и 1введение битумного хоз йства.This method also has disadvantages, which include the need to expend significant quantities of the binder, which are scarce and harmless to health, as well as the need for significant equipment costs, the operation of the coal mixing unit and the binder, and 1 the introduction of bitumen.
Также известен способ получени формованного кокса из углей пониженной спекаемости с толщиной пластического сло 8-12 мм, заключающийс в том, что исходные угли измельчают, Омешивают, полученную смесь напревают до температуры пластичности: 400-450°С и в гор чем состо нии прессуют под давлением 10-15 кг/см полученные формовки прокали1вают и охлаждают 3.A method for producing molded coke from reduced-sintering coals with a plastic layer thickness of 8-12 mm is also known, which means that the source coals are crushed, mixed, and the mixture is heated to a temperature of plasticity: 400-450 ° C and hot pressed pressures of 10–15 kg / cm are obtained by molding calcined and cooled 3.
Недостатком этого юпособа вл етс необходимость сооружени Специальных устройств дл нагрева углей до 400-450°С, а также создание сложных формующих прОцессо.в; кроме того, СЛОЖНО осуществление нрокалкиThe disadvantage of this method is the need to construct Special devices for heating coal to 400-450 ° C, as well as the creation of complex molding processes in; In addition, it is difficult to implement the nanocloc

Technological difficulties are associated with a very narrow temperature range of the plasticity of the coal, as a result of which mass sticking or loss of form is often observed. Received by IKOKC
