Ukulungiselela inqubo ye i-refractory castable

Inqubo yokulungiselela ama-castable aphikisayo, ukungezwa kwe-fiber yensimbi kusimende-i-bonded castable kungathuthukisa ezinye izakhiwo ze-castable: ingathuthukisa ukuqina okuhlobene kwe-castable, ukumelana nokushaqeka komshini, ukumelana nokushaqeka okushisayo, ukumelana nokuqhekeka, nokumelana nokusabalalisa. . Kungase futhi kuvimbele ukushwabana ngemva kokwelapha, ukomisa nokwelashwa kokushisa, ngaleyo ndlela kwandise impilo yesevisi ye-castable.

I-fiber yensimbi esetshenziselwa ukuqinisa i-refractory castable inobubanzi obungu-0.4-0.5mm nobude obungu-25mm. Inani le-fiber yensimbi engezwe ku-castable yi-1-4% (isisindo). Uma i-fiber yensimbi iyinde kakhulu noma inani lokwengeza liningi kakhulu, i-fiber yensimbi ngeke ihlakazeke kalula ngesikhathi sokubunjwa, futhi umphumela omuhle kakhulu wokuqinisa ngeke ufezwe; uma i-fiber yensimbi imfushane kakhulu noma inani lokwengeza lincane kakhulu, umphumela wokuqinisa ngeke ufezwe. Ngakho-ke, ubude nokwengezwa kwe-fiber yensimbi kufanele kube ngokufanele.

I-fiber yensimbi ingaxutshwa enhlanganisweni eyomile, bese wengeza amanzi bese ugoqa ngokulinganayo. Nokho, ngokuvamile, ingxube ixutshwa namanzi kuqala, bese imicu yensimbi ifafazwa ngokulinganayo ku-castable, bese iyanyakaziswa. Lokhu akugcini nje ngokwenza ukuthi ingxube inyakaziswe ngendlela efanayo, kodwa futhi konga u-1/3 wesikhathi sokuhlanganisa uma kuqhathaniswa nokuxutshwa kwemicu yensimbi ezintweni ezomile.

Ukwenza imicu yensimbi ihlakazeke ngokufanayo ku-castable, imicu yensimbi kufanele ihlakazwe ngokufanayo ngokudlidliza noma ngokusefa ngaphambi kokuba yengezwe kokuphonswayo. Ngemuva kokuthulula nokwengeza i-fiber yensimbi, ukusebenza kuzoncishiswa, kodwa akukho manzi engeziwe anganezelwa ukwengezwa, ngaphandle kwalokho amandla okugcina e-castable azobe engathandeki. Ngesikhathi sokubumba, isidlidlizi singasetshenziswa ukudlidliza ngaphandle, noma induku edlidlizayo ingasetshenziswa ukudlidliza ngaphakathi komkhiqizo, futhi kungatholwa imikhiqizo eminyene. Amathuluzi okhuni awakwazi ukusetshenziselwa ukuqeda indawo ngemuva kokubunjwa, ngoba imicu yensimbi izongena ethuluzi futhi ilimaze ubuso bomkhiqizo. Ukuphulukiswa nokomiswa kwama-castable aqiniswe nge-fiber yensimbi kuyefana nama-castable ajwayelekile.
