Umahluko phakathi kwemathiriyeli yeramming ephikisayo kunye ne-refractory castable

Uthini umahluko phakathi kwesixhobo sokurhangqa esinqamkayo kunye nesangqa esilahlayo? Okokuqala, ezi mveliso zimbini zihlelwa njengezinto ezinqandayo ezingamiliselwanga. Imathiriyeli yeramming echasayo yindlela yokwakha esebenzisa iramming kwaye iqiniswe kukufudumeza. I-refractory castable yindlela yokwakha yokuthululela, enokuqina ngaphandle kokufudumeza. Uthini umahluko phakathi kwesixhobo sokurhangqa esinqamkayo kunye nesangqa esilahlayo? Umahluko ulele kwindlela yokwakha kunye nendlela yokuqina. Nceda ubone iinkcukacha ezingezantsi.

Inkcazo yeramming kunye nokugalela

1. Imathiriyeli ekwaziyo ukunqanda, ukuxuba imathiriyeli ephikisayo ebalekayo kwisiza, usebenzisa i-pneumatic pick okanye i-ramming yomatshini, uxinzelelo lomoya alukho ngaphantsi kwe-0.5MPa. Amalungu anemathiriyeli encinci okanye engabalulekanga ukuba asetyenziswe nawo anokugqunywa ngesandla. Yenziwa ngokuxuba i-refractory aggregates, umgubo, izibophelelo, imixube namanzi okanye olunye ulwelo ngokuhlelwa okuthile. Ke ngoko, i-lining ye-refractory kunye ne-refractory ramming materials inomthamo ophantsi wokufuma, amaqhina aqinileyo kunye nokusebenza okungcono kune-refractory kunye ne-refractory castables yezinto ezifanayo. Ukungalungi kwezinto zokunqanda i-refractory refractory ramming isantya sokwakha esicothayo kunye noxinzelelo oluphezulu lwabasebenzi, kwaye kukho ukuthambekela ukutshintshwa kwezinto ezingcangcazelayo ezomileyo kunye nekhwalithi ephezulu yokulahla i-refractory refractory castables.

2. Iintambo zokulahla. Izinto ezirhangqwayo ezilahlwayo ziphoswa, zingcangcazele okanye zifakwe itamped kwindawo yokusetyenziswa, kwaye zisenokwenziwa zibe ziipreforms zokusetyenziswa.

Isicelo kunye nokuhlelwa

Uthini umahluko phakathi kwezixhobo zokurhangqa ezizii-refractory kunye ne-refractory castables? I-refractory castables ine-fluidity ephezulu kwaye isetyenziswa ngokubanzi. Amalungu aneemathiriyeli ezinganyibilikiyo okanye ezingabalulekanga nazo zinokuqhinwa ngesandla. Izixhobo zokunqanda ukunqanda zihlelwa ngokwezinto ezibonakalayo: i-alumina ephezulu, udongwe, i-magnesia, i-dolomite, i-zirconium kunye ne-silicon carbide-carbon refractory ramming materials. I-refractory castables ihlelwa ngokwezinto ezibonakalayo: 1. Ngokwe-porosity, kukho iindidi ezimbini ze-refractory refractory castables kunye ne-thermal insulation refractory materials kunye ne-porosity engekho ngaphantsi kwe-45%; 2. Ngokwe-binder, kukho i-hydraulic bonding kunye nekhemikhali yokudibanisa. , I-Condensation edibeneyo kunye ne-refractory refractory castables.

I-Refractory castable yi-refractory engabunjwanga eyenziwa ngokubanzi kwaye isetyenziswe. Isetyenziselwa ikakhulu ukwakha zonke iintlobo zokufudumeza iileyile zesithando somlilo kunye nezinye izakhiwo. Isetyenziswa ngokubanzi kwisinyithi, i-petroleum, ikhemikhali, izinto zokwakha, amandla ombane, ii-kilns zeshishini loomatshini kunye nezixhobo zokufudumeza, kunye neemveliso ezikumgangatho ophezulu nazo zingasetyenziselwa ukuqeqesha iziko.

Imathiriyeli ye-refractory ramming yimathiriyeli eninzi eyenziwe nge-silicon carbide, igraphite, kunye ne-anthracite yombane ene-calcined njengemathiriyeli ekrwada, exutywe neentlobo ngeentlobo zezongezo zomgubo we-ultrafine, kunye nesamente edibeneyo okanye i-resin edibeneyo njengesibophelelo. Isetyenziselwa ukuzalisa isithuba phakathi kwezixhobo zokupholisa iziko kunye ne-masonry okanye i-filler ye-masonry leveling layer. Imathiriyeli ekwazi ukumelana nomlilo inozinzo olululo lweekhemikhali, ukuxhathisa ukhukuliseko, ukuxhathisa ukonakala, ukunganyangeki, kunye nokumelana nokothuka kobushushu. Isetyenziswa ngokubanzi kwisinyithi, izixhobo zokwakha, uqeqesho lwesinyithi olungeyontsimbi, ishishini lemichiza, oomatshini kunye neminye imisebenzi yemveliso.
