Si nabadgelyo leh ugu shaqee foornada dhalaalaysa induction oo ilaali 7 caadooyin wanaagsan!

(1) Frequently observe the melting situation in the furnace. The charge should be added in time before the charge is completely melted. It is found that the scaffolding should be treated in time to avoid the furnace wearing out due to the sharp rise of the molten iron temperature under the shed, which exceeds the melting point of the charge (quartz sand 1704℃). To

(2) Ka dib marka la dhalaaliyo birta dhalaalaysa, waa in meesha laga saaraa dhoobada oo heerkulka waa in lagu cabiraa waqtiga, birta dhalaalaysa waa in la siidaayaa waqtiga markay gaarto heerkulka foornada. Ku

(3) Xaaladaha caadiga ah, marka darbiga ciriirigu yahay 1/3 ee dhumucda dahaarka foornada asalka ah, waa in foornada la burburiyaa oo dib loo dhisaa. Ku

(4) Birta dhalaalaysa waa in la faaruqiyaa toddobaadkii hal mar si loo cabbiro xajmiga foornada oo la fiiriyo xajmigeeda, si loo fahmo xaaladda dhabta ah ee dahaarka foornada waqtigeeda, iyo in wax laga qabto wixii dhibaato ah ee waqtiga ku timaadda. Ku

(5) Dib -u -hagaajiyaha waxaa ugu wanaagsan in yar oo yar ayaa lagu daraa inta lagu jiro habka lagu darayo lacagta biraha. Ku darista goor hore waxay u hoggaansami doontaa xagga hoose ee foornada oo si fudud ugu milmi maayo birta dhalaashay. Ku darista goor dambe waxay sii dheerayn doontaa waqtiga dhalaalinta iyo kululaynta, taas oo aan kaliya keenin dib -u -dhac ku yimaada hagaajinta halabuurka, laakiin waxay kaloo sababi kartaa heerkul aad u sarreeya. Ku darista ferrosilicon (kordhinta Si), foornooyinka dhalaalaya induction oo leh awood kicis daciif ah, maxaa yeelay waxa ku jira macdanta sare ee Si ee birta dhalaalaysa waxay sababi doontaa kororka C ee liita, waxaa wanaagsan in mar dambe lagu daro Si birta, laakiin waxay keeni doontaa birta foornada . Daahitaanka falanqaynta halabuurka dareeraha iyo hagaajinta. Ku

(6) Ka tagista biraha dareeraha ah ee foornada inta lagu dhalaalayo waxay gacan ka geysan kartaa hagaajinta hufnaanta korantada ee foornooyinka korontada qaarkood waxayna hagaajin kartaa qodobka awoodda wejiga dhalaalka. Si kastaba ha ahaatee, birahaan la shubay ayaa laga yaabaa inay ku kululaadaan foornada muddo dheer waxayna halis geliyaan tayada biraha. Sidaa darteed, biraha la shubay ee haraaga ah waa in lagu xisaabtamaa 15% mugga foornada. Bir aad u yar oo la shubay ayaa sii xumayn doonta gobolka kulaylka badan, iyo birta badan ee la shubay waxay yarayn doontaa adeegsiga waxtarka leh ee birta la shubay waxayna kordhin doontaa isticmaalka tamarta unugga. Ku

(7) Dhumucda kharashka ayaa la doorbidayaa 200 ～ 300mm. Hadba dhumucda weyni, dhalaalku wuu gaabiyaa.
