Umehluko phakathi kwe-refractory ramming material kanye ne-refractory castable

Uyini umehluko phakathi kwe-refractory ramming material kanye ne-refractory castable? Okokuqala, le mikhiqizo emibili ihlukaniswa njengezinto eziphikisayo ezingabunjwanga. I-refractory ramming material iyindlela yokwakha esebenzisa i-ramming futhi yenziwa lukhuni ngokushisisa. I-Refractory castable iyindlela yokwakha yokuthulula, engakwazi ukuqina ngaphandle kokushisa. Uyini umehluko phakathi kwe-refractory ramming material kanye ne-refractory castable? Umehluko usendleleni yokwakha kanye nendlela yokuqina. Sicela ubheke imininingwane ngezansi.

Incazelo ye-ramming nokuthela

1. Impahla ye-ramming eyi-refractory, ukuxuba i-ramming material esizeni, kusetshenziswa i-pneumatic pick noma i-mechanical ramming, ingcindezi yomoya ayikho ngaphansi kuka-0.5MPa. Izingxenye ezinempahla encane noma ezingabalulekile ukuthi zisetshenziswe zingabotshwa ngesandla. Yenziwa ngokuxuba ama-refractory aggregates, izimpushana, izibophezelo, izingxube namanzi noma olunye uketshezi ngokuhlelwa okuthile. Ngakho-ke, ulwelwesi lwezinqamuleli eziphikisayo nezingaguquki lunomswakama ophansi, amafindo aqinile nokusebenza okungcono kunama-refractory kanye ne-refractory castable lento efanayo. Ububi bezinto zokunqanda eziphikisayo isivinini sokwakha esinensayo kanye nomfutho wemisebenzi ephezulu, futhi kukhona ukuthambekela kokushintshwa kwezinto ezomile ezidlidlizayo kanye nezinsimbi eziphikisayo zekhwalithi ephezulu.

2. Ama-castable aphikisayo. Ama-castable e-refractory ngokuvamile ayasakazwa, adlidliziwe noma agxivizwe endaweni yokusetshenziswa, futhi angenziwa abe yizibikezelo ezizosetshenziswa.

Isicelo kanye nezigaba

Uyini umehluko phakathi kwe-refractory ramming materials kanye ne-refractory castables? Ama-refractory castable ane-fluidity ephakeme futhi asetshenziswa kabanzi. Izingxenye ezinezinto zokunqamula ezingaguquki kancane noma izinhlelo ezingabalulekile nazo zingafindwa ngesandla. Izinto zokunqamula eziphikisayo zihlukaniswa ngokwezinto ezingavuthiwe: i-alumina ephezulu, ubumba, i-magnesia, i-dolomite, i-zirconium kanye ne-silicon carbide-carbon refractory ramming materials. Ama-refractory castables ahlukaniswa ngokuya ngezinto ezingavuthiwe: 1. Ngokusho kwe-porosity, kunezinhlobo ezimbili ze-refractory refractory castables kanye ne-thermal insulation refractory materials ene-porosity engekho ngaphansi kwama-45%; 2. Ngokusho kwe-binder, kukhona i-hydraulic bonding kanye ne-chemical bonding. , I-Condensation ehlanganiswe ne-refractory refractory castables.

I-Refractory castable iyi-refractory engakhiwe ekhiqizwa kabanzi futhi isetshenziswe. Isetshenziselwa ikakhulukazi ukwakha zonke izinhlobo zokushisisa ama-linings omlilo nezinye izakhiwo. Isetshenziswa kabanzi ku-metallurgy, petroleum, amakhemikhali, izinto zokwakha, amandla kagesi, ama-kilns embonini yemishini kanye nemishini yokufudumeza, kanye nemikhiqizo yekhwalithi ephezulu ingasetshenziswa futhi ekuqeqesheni izithando.

I-refractory ramming material iyinqwaba eyenziwe nge-silicon carbide, graphite, kanye ne-anthracite kagesi e-calcined njengezinto zokusetshenziswa, exutshwe nezinhlobonhlobo zezithasiselo zempushana eningi, kanye nosimende ohlanganisiwe noma inhlaka ehlanganisiwe njengesibophezelo. Isetshenziselwa ukugcwalisa igebe phakathi kwemishini yokupholisa isithando somlilo kanye ne-masonry noma isigcwalisi sesendlalelo sokulinganisa i-masonry. Impahla ye-ramming engashi inokuqina okuhle kwamakhemikhali, ukumelana nokuguguleka, ukumelana nemihuzuko, ukumelana nokuchithwa, nokumelana nokushaqeka kokushisa. Isetshenziswa kabanzi kwezensimbi, izinto zokwakha, ukuqeqeshwa kwensimbi okungeyona ayoni, imboni yamakhemikhali, imishini kanye neminye imisebenzi yokukhiqiza.
