Description
Примен емые обычно на заводах матерналы дл занравки подин не обеспечнвают непрерывного уда.ченн шлака. Особенно трудно вестн удаление шлака в жидком состо нии на рекуперативных ко.тодцах.The maternals used for the factories that are usually used at the bottom of the furnace do not provide continuous slag removal. It is especially difficult to remove slag in the liquid state on recuperative heat pumps.
Предлагаетс заправочиыГ материал дл подины, обеспечиваюший нормальный еход шлака по ходу нагрева стали при температуре ко.тодца 1300-1350, следуюш,его состава (в %):A filling material is offered for the hearth, which ensures normal slag flow during the heating of steel at a temperature of 1300-1350, its composition (in%):
коксова мелочь, коксик 55-GO кварцевый иесок . . . 35-Юcoke breeze, coking 55-GO quartz sand. . . 35-U

Коксова ме.ючь вводитс д.ти получени на подине восстановите.тьной атмосферы, нри которой окпеь железа восстапав.:1иваетс в закись, а закись железа (закись маргапиа) образует с кремнеземом легкон.чавкие си.ликаты с темиературоГ п.тавлеии 1170-1180°.A coke oven is introduced in order to obtain a reduced atmosphere at a hearth, in which iron is restored: 1 is dissolved in oxide, and iron oxide (margapia oxide) forms easily silica gel with silica and carbon dioxide 1170. 1180 °.
Введеиие извести позвол ет получить двойные и тройные соединени окиси кальци с окисью железа , закисью же.теза, г.1инозе%кп1 п кремнеземом, имеющие температуру плавлени ШЗО-Г250-130П.The introduction of lime makes it possible to obtain double and ternary compounds of calcium oxide with iron oxide, carbon monoxide, g.inose,% silica gel, having a melting point SHZO-G250-130P.
.Материал можно нримен ть в виде смеси, использу д.п заправки обычную бадью, илн в виде кусков, брикетов, забрасываемых на нодину вручную.The material can be applied in the form of a mixture, using a conventional bucket, or in the form of pieces, briquettes, which are thrown onto the nodina manually, using a filling station.
Материа..т имеет высокую -реактивную способность и вырабатываетс без остатка.Materia. Has a high reactivity and is produced without residue.
Проведенные в производственных ус.юви х испытани показали, что нримененне этого материала новышает производительность нагревательных колодцев на 12% при одновременном улучшении качества иагрева.The tests carried out in the production facilities showed that, in the application of this material, the productivity of the heating wells is increased by 12% while improving the quality of heating.
