Ngawaphi amanyathelo okwakha okusebenzisa izinto zokusakha?

Kukho izinto ezininzi ezichaphazela ukusebenza kwee-castables, ezifana nokukhethwa kwezinto eziphathekayo, ukwakhiwa kunye nokugcinwa. Ukubaluleka kolwakhiwo kukwadlala indima ebalulekileyo ekusebenzeni kwee-castables. Lo mhleli ulandelayo uya kukucacisela iindlela zokwakha ezisetyenziswa rhoqo zokusakha:

A. Ukugalela indlela yokwakha

1. Ukuhlolwa: Khangela ukuba i-mold ixhaswe kakuhle, akukho zithuba kunye nokuphambuka, kwaye i-debris kwi-mold ihlanjululwa, ingaba i-anchors (izikhonkwane ze-palladium ezikwazi ukumelana nobushushu) zifakwe ngokuqinileyo, kunye nomphezulu weehange. iqatywe ngepeyinti okanye ingxowa yeplastiki kwi-buffer Amandla okwandisa emva kokufudumeza.

2. Ukuthululela: Thela izinto ezixutywayo zokuthululela kwi-mold, faka intonga yokungcangcazela ukuze ungcangcazele, kwaye uhambise intonga yokungcangcazela ngesantya esifanayo, kwaye ukhuphe ngokukhawuleza.

3. Indawo yokuthululela inkulu kakhulu, inokuthululelwa kwiingqimba kunye neengxenye, kwaye inokuthi iqhutywe. Udonga luthululelwa kwiingqimba, ixesha ngalinye li malunga ne-900mm, phezulu kwesithando somlilo sihlukaniswe kwaye sigalelwe, kwaye emva koko siphakanyiswe.

4. Ukunyanga kunye nokudiliza: iqondo lokushisa lokusingqongileyo>20℃, isikhunta sinokuchithwa emva kwe-4H, <20℃, isikhunta sinokuchithwa emva kokunyanga i-6-7H, ukuba imiphetho yendawo kunye neekona zonakaliswe, inokulungiswa. . (Ixesha elithile lokudiliza lixhomekeke kwiimeko zesayithi).

B. Indlela yokwakha yokuthambisa

1. Okokuqala khangela ukuba i-anchors (izikhonkwane ze-palladium ezikwazi ukumelana nobushushu) zifakwe ngokuqinileyo. Peyinta iiankile okanye uzisongele kwiingxowa zeplastiki ukuze ukhusele amandla okwandisa emva kokufudumeza.

2. Sebenzisa i-manual smearing ye-mixed castable ngqo kwindawo yokusebenza.

3. Indawo yokusebenza iya kusetyenziswa ngokuqhubekayo kwimigangatho ukusuka phezulu ukuya phezulu. Ubude boluhlu ngalunye malunga ne-900mm, kwaye ubukhulu boluhlu ngalunye bu malunga ne-80mm. Xa ubukhulu bufikelela kubungakanani obufunekayo, sebenzisa isixhobo sokupolisha indawo yokwakha.

4. Faka isicelo ngokuqhubekayo phezulu kwendawo yokwakha kumacandelo, kunye necandelo phakathi kwamacandelo amabini okwandisa, ixesha ngalinye i-30-50mm, xa ubukhulu bufikelela kubukhulu obufunekayo, sebenzisa isixhobo sokupolisha indawo yokwakha.

5. Kwi-thermal insulation lining ye-diameter-diameter horizontal pipelines, indlela yokwakha i-lining kumacandelo kuqala kunye nokumisa ukudibanisa kufuneka yamkelwe. Xa umbhobho wakhiwe ngokwamacandelo, beka umbhobho ngokuthe tye, sebenzisa umgca we-semicircular esezantsi kuqala, kwaye emva kokunyanga kwemvelo kwi-4-8h, vula umbhobho we-180 ° kwaye usebenzise enye i-semicircular lining, kwaye wenze unyango oludibeneyo emva kokuba umbhobho uphelile. iqhagamshelwe.

C. Ukutshiza indlela yokwakha

1. I-Weld metal palladium izikhonkwane okanye i-mesh yensimbi (intsimbi enganyangekiyo ubushushu) kwiqokobhe lesithando somlilo kuqala.

2. Faka ipeyinti yokutshiza kwisitshizi, sebenzisa umoya oxinanisiweyo (uxinzelelo 0.10-0.15MPa) ukuthumela umxube kwi-nozzle, kwaye wongeze ubungakanani obufanelekileyo bamanzi okanye i-agent yokudibanisa imichiza ukuxuba kunye nempahla, kwaye uyitshize kwi-nozzle. indawo yokwakha.

3. I-nozzle outlet kufuneka ibe yi-perpendicular kumgangatho wokwakha, umgama u-1-1.5m, ukutshiza kufuneka kuqhubeke, kwaye ubukhulu be-spraying nganye kufuneka bube ngaphantsi kwe-200mm.

4. Ukuba umgca wokutshiza womhlaba wokwakha unzima kakhulu, kufuneka utshizwe kwiingqimba, kodwa kufuneka uqhutywe emva kokuba uluhlu lwangaphambili lunamandla okwaneleyo. Emva kokutshiza, indawo yokusebenza kufuneka igudiswe kwaye i-rebound material kufuneka ihlambuluke.

Ukushwankathela, ukulandela ngokungqongqo iindlela zokwakha kunye namanyathelo adlala indima ebalulekileyo ekusebenzeni kwe-refractory castables.
