With the rapid development of high-temperature industrial fields, metallurgical heat-resistant steel has become the preferred material for the manufacture of key equipment in petrochemical, power, metallurgical and other industries due to its excellent high-temperature strength, oxidation resistance and creep resistance. Si kastaba ha noqotee, tayada kuleylka dhismaha {{4 {4 {4- bir adag ayaa si toos ah u saameeya nolosha adeegga iyo badbaadada qalabka, sidaa darteed waa muhiim in si adag loola socdo heerarka dhismaha.
Xulashada maaddada iyo ka-hortagga
Dhismaha kuleylka madaxa, {0 0}} bir iska caabbinta waa in la hubiyaa in sheyga uu buuxiyo heerarka caalamiga ah ama warshadaha, sida ASTM, ASME ama GB / T. Kuleylka caadiga ah - fasalada birta cayayaanka ee iska caabbinta waxaa ka mid ah 310s, 309s, 309s, GMNTH. Darajooyin kaladuwan ayaa ku habboon heerkulka kala duwan iyo jawiga laxiriira. Falanqaynta muuqaalka ah, tijaabada adag iyo tijaabada tijaabada ah ee wax burburka ah ayaa loo baahan yahay ka hor intaan alaabtu ku soo galin goobta si loo hubiyo in halabuurka iyo waxqabadka uu buuxiyo heerarka. Intaas waxaa sii dheer, kuleylka {{10} il yar oo iska caabbinta ayaa loo baahan yahay in la dhinto ka hor inta uusan alxami ka dhigin walaaca iyo ka fogaanshaha dillaacyada.
Xakamaynta hannaanka alxanka
Welding is the core link in the construction of heat-resistant steel, and the process parameters need to be strictly controlled. Qaabka alxanka ayaa caadiyan qaadaya alxanka Wing ee Weelka, alxanka iyo alxanka laser, iyo doorashada gaarka ah waxay kuxirantahay dhumucda qadhaadhka iyo shuruudaha dhismaha. Weelka alxanka, korantada iyo xawaaraha waxay u baahan yihiin in lagu hagaajiyo iyadoo loo eegayo guryaha, iyo kuleylka u dhigma {{3} {{3} {{3} {{3} {{3} {{3} oo ah in la isticmaalo qalabka alxanka ee ugu adkaysata. Markay yihiin meelo badan oo lakab ah, iyo kala weyne - meel dhulka dhexdiisa ah, oo heerkulka isdhaafsadana wuxuu u baahan yahay in lagu xakameeyo nooc macquul ah si looga fogaado in lagululaado iyo jaranjarada hadhuudhka. Ka dib alxamida, aan ahayn {- imtixaanka al-{{- ee Weld (sida UT, RT) ayaa loo baahan yahay si loo hubiyo tayada.
Daaweynta kuleylka iyo kormeerka
Kuleyl {{0} saliida iska caabbinta badanaa waxay u baahan tahay in kuleylka la daaweeyo ka dib dhismaha, oo ay kujirto xalka daaweynta ama daaweynta xasilinta, si loo baabi'iyo walaaca hadhaaga ah oo loo saadaaliyo waxqabadka mikraal-ka. Heerkulka kuleylka kuleylka iyo waqtiga waa inuu si adag ula socdaa sharaxaadaha sheyga si looga fogaado inuu ka fogaado ama uu hooseeyo. Kormeerka ugu dambeeya waxaa ka mid ah kormeerka macroscopic, tijaabada adag iyo sare ee imtixaanka jilicsan ee heerkulka si loo hubiyo in sheyga uu buuxiyo shuruudaha naqshadeynta.
Badbaadada iyo Ilaalinta Deegaanka
Kuleyl - dhisme jilicsan oo u adkaysta Isla mar ahaantaana, qiiqa iyo qalabka qashinka waa in si sax ah loo maareeyaa si loo buuxiyo shuruudaha ilaalinta deegaanka.
Barashada Heerarka Dhismaha ee kuleylka 'Metallusckical' {{0 0}} bir iska caabbinta ah ma hagaajin karo oo keliya tayada mashruuca, laakiin waxay sidoo kale kordhineysaa nolosha qalabka oo u abuuraan qiimo sare shirkada.
