Kuʻi paʻakikīElectrode
Kūlana: DIN 8555 (E1-UM-350)
ʻAno ʻAno: TY-C DUR 350
Hōʻike a me ka noi:
· ʻO ka electrode SMAW i uhi ʻia no ka māwae a me ka ʻaʻahu ʻana i ka ʻili.
· Kūleʻa abrasion maikaʻi.Maʻalahi e wili ma nā kūlana a pau.
· Ua kūpono loa no ka ʻaʻahu ʻana i ka ʻili ma luna o nā ʻāpana i hoʻohui ʻia ʻo Mn-Cr-V, e like me nā rana, track rollers, chain support rolls, sprocket wheels, guide rolls etc.
Hoʻohui kemika o ka metala i waiho ʻia(%):

Nā ʻano maʻamau:
· Microstructure Ferrite + Martensitic
· Maikaʻi maikaʻi me ka Tungsten carbide nā mea hana
· Preheating E hoʻomaʻamaʻa mua i nā ʻāpana kaumaha a me nā kila kiʻekiʻe-tensile i 250-350 ℃
· Hoʻomaʻa hou i ka Redry no 2 mau hola ma 300 ℃ ma mua o ka hoʻohana ʻana.
