Abstract

Поплавъкът намира приложение в металургичната промишленост. Състои се от метален прът (1), минаващ през разширено керамично дъно (2), от което е издадена надолу цилиндрична керамична къса съединителна част (3), конструирана така, че да се разположи в изпускателния отвор на пещта. Около късата съединителна част (3) е осигурена тръбна наставка (4) от въглероден или реактивен материал, от който можеда бъде изработена и облицовка (5) на дъното (2) на поплавъка. Втулка (6) от подходящ реактивен материал може да бъде разположена върху челната повърхност (7) на поплавъка. Реактивният материал можеда бъде дървен материал или хартия, или реактивен метал, например алуминий или магнезий. При последващата химична реакция с разтопената стомана се формира струя, която разчиства шлаката около изпускателния отвор.
