Yadda za a zabi tubali masu ratsa jiki ga kowane bangare na fashewar tanderun?

fashewar tanderu babbar tanderu ce ta pyrometallurgical wacce ke amfani da coke don rage taman ƙarfe don narke narkakkar ƙarfe. Zazzabi, matsa lamba, kaddarorin jiki da sinadarai da matsananciyar yanayin aiki na rufin a wurare daban-daban na tanderun fashewar sun bambanta. Sabili da haka, tsarin da yanayin gazawar rufi suma sun bambanta, kuma zaɓin kayan da ke da alaƙa ya bambanta ta halitta.

① Furnace Maƙogwaro

fashewar makera makogwaro shine makogwaro na tanderun fashewar, wanda ke samun sauƙin lalacewa ta hanyar tasiri da gogayya yayin aiwatar da ɓarna. Masonry gabaɗaya an gina shi da tsayin daka, tubalin alumini mai girma mai yawa, kuma ana kiyaye shi ta hanyar simintin ƙarfe masu jure lalacewa.

② Jikin murhu

Jikin tanderun shine ɓangaren daga makogwaron tanderun zuwa tsakiyar kugun tanderun, wanda ya kasu kashi uku: babba, tsakiya da ƙasa. Rubutun tsakiya da na sama na rufin tanderan galibi ana sawa ne kuma lalata su ta hanyar faɗuwar abu da ƙura mai ɗauke da iska, kuma lalacewar tana da ɗan haske. A ƙarƙashin yanayi na al’ada, tubalin yumbu na musamman, tubalin yumbu mai yawa, da manyan bulogin alumina tare da ƙarancin abun ciki na Fe2O3 kuma na iya amfani da yumbu amorphous refractories. Ƙananan ɓangaren jikin tanderun yana da yawan zafin jiki kuma an kafa adadi mai yawa na slag. Slag ɗin yana cikin hulɗar kai tsaye tare da saman rufin tanderun, kuma rufin tanderun yana lalacewa da sauri. Masonry gabaɗaya yana zaɓar bulogin yumbu mai inganci ko manyan bulogin alumina tare da kyakkyawan juriya na wuta, juriya mai ƙarfi, ƙarfin tsarin zafin jiki da juriya. Ƙarƙashin babban shingen murhun tanderu yana amfani da manyan bulogin alumina, bulogin corundum, tubalin carbon ko tubalin siliki carbide.

③ Wutar wuta

Kugu shine mafi faɗin ɓangaren tanderun fashewar. Rushewar sinadari na slag, tururin ƙarfe na alkali, da juzu’i da lalacewa na coke mai zafi da zafi a saman rufin tanderun na da matukar muni, wanda ya sa ya zama ɗaya daga cikin ɓangarori masu rauni na tanderun fashewar. Matsakaici da ƙananan murhun wuta na iya amfani da tubalin yumbu mai ƙima, manyan bulogin alumina, da tubalin corundum; manyan murhun fashewa na zamani gabaɗaya suna amfani da manyan bulogin alumina, tubalin corundum ko tubalin carbide na silicon, kuma ana iya amfani da tubalin carbon don ginin gini.

④ Tushen ciki

Ciki na tanderun yana ƙarƙashin kugu na tanderun kuma yana da siffar mazugi mai jujjuya. Gabaɗaya, tanderun fashewar ta kusan lalacewa jim kaɗan bayan buɗe ta. Sabili da haka, ana amfani da tubalin alumina masu girma (Al2O3 <70%) da tubalin corundum a cikin murhu. Bulo na carbon, graphite man coke, graphite anthracite da sauran Semi-graphite tubalin ana amfani da ko’ina a cikin zamani manyan fashewa tanderu.

Ƙaddamar da Hearth

Wutar murhu ta fi shafa ne sakamakon zaizayar sinadarai, yazawa da zaizayar alkali na zubewar tukwane da narkakken ƙarfe. A kasan tanderun, narkakkar baƙin ƙarfe yana shiga cikin tsagewar bulo, wanda hakan ya sa na’urar ta yi iyo kuma ta lalace. Masonry gabaɗaya yana amfani da tubalin carbon tare da ƙarfin juriya na wuta, ƙarfin zafin jiki mai ƙarfi, juriya mai kyau, ƙarfin zafin jiki mai ƙarfi, babban girman girma da kwanciyar hankali mai kyau.
