Abstract

Шлакообразуващата смес се използва при производството на стоманени блокове и метални изделия от тях. Тя е с температура на топене от 1200 до 12800с, дава плътен шлаков слой с дебелина от 30 до 50 мм и не отделя вредни газове при разливането на стоманата. Шлакообразуващата смес съдържа в мас.% Следните компоненти: si02 от 40 до 54, аl203 от 14 до 22, сао от 13 до 22, мg0 1-2, fе203 от 3 до 8, к20 1-2 и nа20 0,5-1. Окисният състав е получен от отпадъчна тецова пепелина и цимент или хидратна вар и/или варова пепелина. 3 претенции есThe slag-forming mixture is used in the production of steel blocks and metal products from them. It has a melting temperature of 1200 to 12800c, gives a dense slag layer with a thickness of 30 to 50 mm and does not emit harmful gases when the steel is poured. The slag-forming mixture contains in wt.% the following components: si02 from 40 to 54, al203 from 14 to 22, cao from 13 to 22, mg0 1-2, fe203 from 3 to 8, k20 1-2 and na20 0.5-1 . The oxide composition is obtained from waste fly ash and cement or hydrated lime and/or lime ash. 3 claims es
