Hanyoyin da za a rage lalata farashin rufin wuta a cikin tanderu

Ta hanyar babban adadin binciken gwajin juriya na slag da ainihin aiki na mai canzawa, ana iya samun wasu ilimin juriya na lalatawar rufin rufin:

(1) Abubuwan da ke tattare da narkakkar baƙin ƙarfe yana da tasiri mai mahimmanci akan rayuwar rufin rufin, abun ciki na silicon, gandun daji, da sulfur.

(2) Maɗaukakin zafin ƙarshe na mai canzawa zai haifar da raguwa a cikin rayuwar rufin tanderun. Lokacin da ƙarshen zafin jiki ya wuce 1700 ° C, kowane haɓaka 10 ° C zai haɓaka ƙimar lalatawar murfin tanderu.

(3) Ƙara yawan alkalinity na slag yana da amfani don rage lalata na slag zuwa mahimmanci na asali.

(4) Ƙara abun ciki na Mg0 a cikin slag zai iya rage lalatar da aka yi a kan rufin murfi na tanderun.

(5) Ƙara abun ciki na Fe0 a cikin slag zai haifar da lalatawar kayan da aka lalata na rufin tanderun.

(6) A cikin matakin farko na jujjuyawar mai canzawa, ainihin tushen slag yana da ɗan ƙaramin ƙarfi, kuma rufin ya lalace sosai. Ya kamata a yi amfani da slag na Dolomite don yin abun ciki na Mg0 a cikin slag kusa da cikakken jihar.

(7) Fluorite kuma yana lalata rufin tanderu, don haka adadin fluorite da aka saka ya kamata a rage gwargwadon yiwuwar.

(8) Daga cikin dolomite da magnesia dolomite refractories, Mg0 yana da mafi kyau slag yashwa juriya fiye da Ca0, amma gaban Ca0 iya inganta high zafin jiki thermoplasticity da slag shigar azzakari cikin farji juriya na refractories.

(9) The raw kayan na tanderun rufi refractories ake bukata don samun mafi girma tsarki. Misali, yashi dolomite magnesium yana buƙatar jimlar ƙazanta na SiO2+A12O3+FeO ƙasa da 3%; wasu kamar fused magnesia, graphite, da dai sauransu suma suna da buƙatu iri ɗaya.
