Description
Wynalazek dotyczy utwardzania szkla przez równomierne ogrzewanie i szybkie chlodzenie go.Szybe wzglednie przedmiot szklany o- grzewa sie do temperatury mieknienia, to znaczy okolo 900°C, w stopionym metalu lub mieszaninie metali. Po ogrzaniu chlo¬ dzi sie przedmiot szklany razem z kapiela metalowa w zimnej wodzie lum w strumie¬ niu powietrza.Szklo, w ten sposób utwardzone, jest przeznaczone przede wszystkim do wyro¬ bu szyb pojazdowych nie kaleczacych przy rozbiciu. PLThe invention relates to the hardening of glass by uniform heating and rapid cooling of it. A relatively fast glass object is heated to its softening temperature, that is to say about 900 ° C., in a molten metal or metal mixture. After heating, the glass object is cooled together with the metal drip in cold water or in a stream of air. The glass, thus hardened, is intended primarily for the manufacture of non-injurious vehicle windows when broken. PL
