Igama: Zirconium ityhubhu intonga
Zirconium alloy tubular material is made from zirconium metal and other metals. Due to the excellent nuclear properties and corrosion resistance of zirconium, zirconium alloy tube rods are often used for nuclear fuel assemblies and in-stack structures in water-cooled reactors and are an important nuclear material. Pure zirconium tubular rods are mainly used in the manufacture of chemical equipment, as they are expensive and not yet used in large quantities. The chemical composition of the commonly used zirconium pipe rods and their applications are shown in the table, among which zirconium-tin alloy pipe rods are used more often.
1) I-Zirconium inobuhlobo obomeleleyo neegesi, iqala ukusabela ngeoksijini, hydrogen kunye ne-nitrogen malunga 200, 300 kunye no-400 ° C ngokwahlukeneyo, kwaye iphendula ngokukhawuleza kumaqondo aphezulu obushushu, ngaloo ndlela ukunyibilika nokuphosa, unyango lobushushu kufuneka lwenziwe kwiziko lokucoca umlilo. Xa ukwenziwa kobushushu kuqhutyelwa emoyeni, amanyathelo okhuseleko afanelekileyo kufuneka athathwe kwaye ixesha lokusebenza kumaqondo obushushu aphezulu kufuneka ancitshiswe.
(2) I-Zirconium inomlingani ophezulu wokungqubana kunye nokubumba kwaye kulandelwa ngokulula kumphezulu womngundo; ifuthe thermal deformation zeplastiki kubalulekile, kwaye iimeko zokuthambisa ezifanelekileyo ziyafuneka ukuze zilungiswe.
(3) Inkqubo yokucaciswa inefuthe elibuthathaka ngakumbi ekusebenzeni kwemveliso. Ingqwalaselo eyodwa kufuneka ihlawulwe kulawulo lwemveliso egqityiweyo ngaphambi kwenkqubo yokubanda kunye nenkqubo yokunyanga ubushushu ukuhlangabezana neemfuno zokusetyenziswa.
(4) Ukuchaneka komlinganiso kunye nomgangatho womgangatho wombhobho kunye nebha ziphezulu kakhulu. Ke ngoko, izixhobo zenkqubo kufuneka zibe nokuchaneka okuhle, uyilo nokuvunda kunye nemveliso kufuneka phambili kunye nengqiqo
