Izinti ze-Brazing ezisetshenziselwa ukushisela i-PDC cutter

Zithini izinduku zokubhebha

Ama-brazing rods ayizinsimbi zokugcwalisa ezisetshenziswa enqubweni yokubhula, okuyindlela yokuhlanganisa esebenzisa ukushisa nezinto zokugcwalisa ukuze kuhlanganiswe izingcezu zensimbi ezimbili noma ngaphezulu ndawonye., njengensimbi ukuya ensimbi noma ithusi ukuya ethusi. Ama-brazing rods ngokuvamile enziwe nge-alloy yensimbi enephuzu elincibilikayo eliphansi kunezinsimbi eziyisisekelo ezihlanganiswayo. Izinhlobo ezijwayelekile zama-brazing rods zihlanganisa ithusi, ithusi, isiliva, ne-aluminium alloys. Uhlobo oluthile lwe-brazing rod olusetshenziswa luncike ezintweni ezihlanganiswayo kanye nezakhiwo ezifunwayo zelunga lokugcina.

Uhlobo lwe-brazing rods

Uhlobo lwama-brazing rods olusetshenziswa luncike ekusetshenzisweni okuqondile kanye nezinto ezihlanganiswayo. Ezinye izinhlobo ezijwayelekile ze-brazing rods zihlanganisa:

1. I-Brass Brazing Rods: Lezi zinduku zenziwe nge-copper-zinc alloy futhi zivame ukusetshenziselwa ukuhlanganisa izinto zethusi, zethusi, nezethusi.

2. I-Bronze Brazing Rods: Izinti zethusi zenziwe ngama-alloy e-copper-tin futhi zivame ukusetshenziselwa ukuhlanganisa insimbi, insimbi ewukhonkolo, nezinye izinsimbi.

3. Ama-Silver Brazing Rods: Amarodi esiliva aqukethe iphesenti eliphezulu lesiliva futhi asetshenziselwa ukuhlanganisa izinhlobonhlobo zezinsimbi, okuhlanganisa ithusi, ithusi, insimbi engagqwali, nama-nickel alloys. Banikeza amalunga aqinile futhi anokwethenjelwa.

4. Ama-Aluminium Brazing Rods: Lezi zinduku zakhelwe ngokukhethekile ukuhlanganisa i-aluminiyamu nama-alloys. Ngokuvamile aqukethe i-silicon njengengxenye eyinhloko ye-alloying.

5. I-Flux-coated Brazing Rods: Amanye ama-brazing rods afika ne-flux coating, esiza ukususa ama-oxide futhi athuthukise ukugeleza kwensimbi yokugcwalisa phakathi nenqubo yokubhula. Izinti ezinamekwe nge-flux zivame ukusetshenziselwa ukubraza ithusi, ithusi, nezinto zethusi.

Twayesebenzisa izinduku zokubhulaI-PDCumsiki welding

Abasiki be-PDC baboshwe kunsimbi noma emzimbeni we-matrix we-PDC drill bit. Ngokwendlela yokushisa, indlela yokushisa ingahlukaniswa ngokushisa amalangabi, i-vacuum brazing, i-vacuum diffusion bonding, i-high-frequency induction brazing, i-laser beam welding, njll. I-Flame brazing kulula ukuyisebenzisa futhi isetshenziswa kabanzi.

Uma ubhula izisiki ze-PDC, kubalulekile ukusebenzisa induku yokubraza enephuzu lokuncibilika eliphansi kunempahla yokusika ye-PDC ukuvikela ukulimala komsiki. Inqubo ye-brazing ihlanganisa ukushisa i-brazing rod kanye nomhlangano we-PDC cutter ezingeni lokushisa elithile, okuvumela i-alloy brazing incibilike futhi igeleze phakathi komsiki kanye ne-substrate, okwenza isibopho esiqinile.Ngokuvamile, ama-alloys esiliva e-brazing avame ukusetshenziselwa ukushisela i-PDC cutter, ngokuvamile akhiwa ngesiliva, ithusi, nezinye izici ukuze kuzuzwe izici ezifunekayo. Lawa ma-alloys anokuqukethwe okuphezulu kwesiliva, indawo encibilikayo ephansi kanye nezinto ezinhle zokumanzisa. Okuqukethwe kwesiliva okuphezulu kuqinisekisa ukumanzisa okuhle nokuxhumana phakathi kwe-PDC cutter kanye nokokusebenza komzimba we-drill bit.

Kunezinduku zokubhula ezisiliva kanye nepuleti lokubhula elisiliva, elingasetshenziselwa kokubili ukushisela abasiki be-PDC. Ngokuyisisekelo izinduku zokubhula zesiliva ezinesiliva ezingama-45% kuya ku-50% zifanele ukushiselwa kwe-PDC cutter. Ibanga elinconywayo le-silver brazing rods kanye nepuleti yibanga le-Bag612, elinokuqukethwe okungu-50% kwesiliva.

Izinga lokushisa lokubhoda lapho ushisela izisiki ze-PDC.

Ukushisa okuhlulekayo kwesendlalelo sedayimane se-polycrystalline cishe ku-700 ° C, ngakho-ke izinga lokushisa ledayimane kufanele lilawulwe ngaphansi kuka-700 ° C ngesikhathi senqubo yokushisela, ngokuvamile i-630 ~ 650 ℃。

Sekukonke, ama-brazing rods adlala indima ebalulekile ku-PDC cutter welding, ukuqinisekisa isibopho esiqinile nesithembekile phakathi komsiki we-PDC kanyedrill bit body, okubalulekile ekusebenzeni nokuqina kwamathuluzi okumba embonini kawoyela negesi.

Uma udinga i-PDC cutter, izinduku ze-brazing zesiliva, noma amathiphu amaningi wokushisela. Siyakwamukela ukuxhumana nathi nge-imeyiliIrene@zzbetter.com.
