Abstract

Устройство для периодического запирания лётки 2 конвертера 1 имеет форму цилиндрической заглушки 5, смесь 10 которой составлена из компонентов 14 глины, соединений 15 углеводородов и термореактивных пластмасс 16, а также других обеспечивающих деформируемость компонентов. Соединения 15 углеводородов в форме шаровидной полистирольной пены и термореактивные пластмассы в форме эпоксидной порошковой смолы делают заглушку 5 легче и придают полезные свойства деформируемости, а также отверждения. Примешивание пластмассы и термореактивной пластмассы при установке в лётку 2 заглушки 5 дает более высокую стабильность при хранении, быстрое отверждение в лётке 2, преимущественно при постоянных и длинных цилиндрических лётках 2. При попадании сырцевой стали 12 быстрое плавление пластмассы и испарение являются гарантией того, что вся заглушка 5 тоже надежно выносится с жидкой сырцевой сталью 12.The device for periodically locking the tray 2 of the converter 1 has the form of a cylindrical plug 5, a mixture 10 of which is composed of clay components 14, hydrocarbon compounds 15 and thermosetting plastics 16, as well as other components that provide for deformability. Compounds of 15 hydrocarbons in the form of spherical polystyrene foam and thermosetting plastics in the form of epoxy resin powder make plug 5 easier and give useful properties of deformability as well as curing. Mixing plastic and thermosetting plastic when installed in a fly 2 plugs 5 gives a higher storage stability, fast hardening in a fly 2, mainly with constant and long cylindrical swings 2. When raw steel 12 gets in, fast plastics melting and evaporation guarantee that plug 5 is also reliably removed with liquid raw steel 12.
