Uma ufakaiziphambano, kungcono silandele izindlela ezilungile zokuqinisekisa ukusetshenziswa kwazo okuphephile nokusebenza kahle.Nazi ezinye iziphakamiso:
Indlela Engalungile: Gwema ukushiya isikhala esincane phakathi kwezitini ezisekelayo kanye ne-crucible.Isikhala esinganele singaphazamisa ukunwetshwa kwe-cruciblengesikhathi sokushisa, okuholela ekuqhekekeni nasekuhlulekeni okungenzeka.
Indlela Enconyiwe: Faka izingcezu zokhuni ezincane phakathi kwe-crucible nezitini ezisekelayo.Lezi zingcezu zokhuni zizoshisa ngesikhathi sokushisa, zenze indawo eyanele yokwandisa.
Izinyathelo zokuphepha ngesikhathi sokufakwa:
Ngaphambi kokufaka i-crucible, hlola ingaphakathi lesithando somlilo.Izindonga zesithando somlilo kanye nephansi kufanele kuphelele ngaphandle kwensimbi noma izinsalela ze-slag.Uma kukhona usimende noma i-slag enamathela ezindongeni noma phansi, kufanele ihlanzwe.Uma kungenjalo, ukuqhubeka kwelangabi kungase kuvinjwe, kubangele ukushisa okweqile kwendawo, i-oxidation, noma izimbobo ezincane ezindongeni ezibohlayo.
Ukusekela isisekelo se-crucible:
Uma ufaka i-crucible, sebenzisa isisekelo esiyisilinda esikhulu ngokwanele esilingana naleso sesisekelo se-crucible.Isisekelo kufanele sibe sikhulu kancane ngo-2-3 cm, futhi ukuphakama kwaso kufanele kudlule imbobo kampompi ukuvimbela ukuchayeka okuqondile kwesisekelo se-crucible elangabini.Lokhu kusiza ukuvimbela ukuguguleka okusheshayo kwezinto eziyisisekelo, okungaholela ekutheni i-crucible ibe yi-conical noma iqhekeke ngenxa yengcindezi engalingani esisekelweni.
Ukuze uvimbele ukunamathela phakathi kwe-crucible nesisekelo, beka ungqimba lwezinto zokufakelwa (njengesihlabathi esihle esiphikisayo noma amakhadibhodi) phakathi kwazo.
Uma usebenzisa isithando somlilo esitshekisayo esinesisekelo sohlobo lwe-falcon, qinisekisa ukuthi ama-protrusions kusisekelo afana nemisele ye-crucible.Uma ama-protrusions ephakeme kakhulu noma emakhulu, angase abe nengcindezi eyeqile kusisekelo se-crucible, okuholela ekuqhekekeni.Ukwengeza, ngemva kokutshekiswa, i-crucible ingase ingalungiswa ngokuphepha.
Kuma-crucible anama-spouts athelayo amade, kubalulekile ukunikeza isisekelo esinosayizi owanele futhi uvikele ukusekela kwe-crucible.Ukwesekwa okungafanelekile kwesisekelo kungabangela "ukulenga" kwe-crucible kuphela nge-spout ngaphakathi kwesithando somlilo, okuholela ekuqhekekeni okuvela engxenyeni engenhla.
Ukususwa phakathi kwezitini ezicijile nezisekelayo:
Igebe phakathi kwe-crucible kanye nezitini ezisekelayo kufanele libe nokwanele ukuhambisana nokwandiswa kwe-crucible ngesikhathi sokushisa.Ukubeka izinto ezivuthayo (njengezingcezu zokhuni noma amakhadibhodi) ngokuqondile phakathi kwe-crucible kanye nezitini ezisekelayo eziphezulu kungakha isikhala esidingekayo.Lezi zinto ezivuthayo zizosha ngesikhathi sokushisisa i-crucible, kushiye ngemuva imvume eyanele.
Ezithandweni lapho igesi yokukhipha igesi ikhishwa khona ohlangothini, ukuvala igebe phakathi kwe-crucible nodonga lwesithando somlilo ngoboya bokufakelwa kanye nokuwulungisa nge-high-temperature resistant simende.Lokhu kuvimbela i-oxidation kanye nokuqhekeka phezulu kwe-crucible ngenxa yokuvaleka okungafanele ophahleni lwesithando somlilo.Iphinde ivikele izakhi zokushisa ngesikhathi sokunwetshwa okuphezulu kwe-crucible.
(Qaphela: Kutuswa ukusebenzisa isembozo se-crucible ukuze kuvinjwe i-oxidation, ukuqhekeka okuphezulu, kanye nokugqwala. Unqenqema olungaphakathi lwekhava ye-crucible kufanele lumboze ingaphakathi le-crucible kufika ku-100mm ukuze linikeze isivikelo esingcono ngokumelene nemithelela yangaphandle kanye ne-oxidation.)
Ezithandweni ezitshekisayo, ngaphansi kwe-spout yokuthulula kanye nengxenye yokuphakama kwe-crucible, beka isitini esisodwa noma ezimbili ezisekelayo ukuze uvikele i-crucible.Faka ikhadibhodi phakathi kwe-crucible nezitini ezisekelayo ukuze ugcine isikhala esanele futhi uvimbele isithiyo ngesikhathi sokunwetshwa kwe-crucible.
Ngokulandela le mihlahlandlela kanye nokuthobela izinqubo zokufaka ezifanele, ukusebenza kanye neminyakazo yokuphila kwama-crucibles kungakhuliswa.Ukuqinisekisa ukufakwa kwe-crucible okuphephile nokusebenzayo
