Kev Tsim Cov Txheej Txheem Ntawm Ti 6242 Titanium Rods Hauv Kub Extrusion

Ti 6242 titanium rods thiab titanium alloy rods billet thermal conductivity yog tsawg, nyob rau hauv lub kub extrusion yuav ua rau lub nto txheej thiab lub puab txheej ntawm zoo kub txawv, thaum kub ntawm lub extrusion lub tog raj kheej yog 400 degrees, qhov kub ntawm qhov sib txawv yuav ncav cuag 200. ~ 250 degrees. Nyob rau hauv lub suction reinforcing thiab billet seem muaj ib tug loj kub sib txawv nyob rau hauv lub sib koom ua ke ntawm lub billet nto thiab qhov chaw ntawm cov hlau los tsim ntau yam sib txawv zog zog thiab cov khoom yas, nyob rau hauv cov txheej txheem extrusion yuav ua rau uneven deformation, nyob rau hauv lub nto txheej. ntawm qhov loj ntxiv tensile stresses, los ua nyob rau hauv lub extrusion ntawm nto ntawm cov khoom los tsim cov kab nrib pleb thiab kab nrib pleb ntawm cov hauv paus hniav. Titanium rods thiab titanium alloy bar cov khoom kub extrusion txheej txheem tshaj aluminium alloys, tooj liab alloys, thiab txawm steel extrusion txheej txheem yog ntau complex, uas yog txiav txim los ntawm lub titanium rods thiab titanium alloy bar tshwj xeeb lub cev thiab tshuaj.

Muaj titanium alloy hlau ntws dynamics kev tshawb fawb qhia tau hais tias nyob rau hauv lub kub cheeb tsam sib haum mus rau lub sib txawv theem xeev ntawm txhua lub alloy, cov ndlwg tus cwj pwm ntawm cov hlau zoo li txawv heev. Yog li ntawd, ib qho ntawm cov ntsiab lus tseem ceeb cuam tshuam rau extrusion ntws cov yam ntxwv ntawm titanium rods thiab titanium alloy rods yog lub billet cua sov kub uas txiav txim siab theem lub xeev ntawm cov hlau. Extrusion ntawm ib lossis a + P theem cheeb tsam kub ua rau cov hlau tsis sib xws piv rau extrusion ntawm p theem cheeb tsam kub. Qhov nyuaj ntawm kev tau txais cov khoom zoo ntawm cov khoom extruded yog qhov zoo. Txog rau tam sim no, lub extrusion ntawm titanium alloy rods yuav tsum tau siv cov lubricants. Qhov laj thawj tseem ceeb rau qhov no yog tias titanium tsim cov khoom siv fusible eutectic nrog cov hlau los yog npib tsib xee-based alloy tuag cov ntaub ntawv ntawm qhov kub ntawm 980 degree thiab 1030 degree C. Qhov no ua rau muaj zog tuag hnav.

Cov yam tseem ceeb cuam tshuam rau cov hlau ntws thaum extrusion.
(1) Extrusion txoj kev. Rov qab extrusion dua rau pem hauv ntej extrusion hlau ntws uniformity, txias extrusion dua kub extrusion hlau txaus uniformity, lubricated extrusion tshaj tsis-lubricated extrusion hlau txaus uniformity. Cov nyhuv ntawm txoj kev extrusion yog pom los ntawm kev hloov ntawm kev sib txhuam.
(2) Extrusion ceev. Lub inhomogeneity ntawm hlau ntws nce raws li qhov extrusion ceev nce.
(3) Extrusion kub. Qhov tsis sib xws ntawm cov hlau nce thaum lub extrusion kub nce thiab deformation kuj ntawm cov billet txo. Nyob rau hauv cov txheej txheem extrusion, yog tias qhov kub thiab txias ntawm lub extrusion chim thiab tuag yog tsawg heev, thiab qhov kub ntawm qhov sib txawv ntawm txheej txheej thiab hlau nyob rau hauv nruab nrab txheej yog loj, lub unevenness ntawm hlau txaus nce. Qhov zoo dua qhov thermal conductivity ntawm cov hlau, qhov sib txawv ntawm qhov kub thiab txias ntawm qhov kawg ntawm lub ntsej muag ntawm lub ingot billet.
(4) Hlau zog. Tag nrho lwm yam kev mob sib npaug, qhov siab dua cov hlau, qhov sib txawv ntawm cov hlau ntws ntau dua.
(5) Lub kaum sab xis tuag. Qhov loj dua lub kaum sab xis tuag (piv txwv li lub kaum sab xis ntawm lub ntsej muag tuag thiab qhov chaw nruab nrab), qhov tsis sib xws ntawm cov hlau ntws ntau dua. Thaum siv ntau qhov tuag extrusion, tuag qhov kev npaj yog tsim nyog, cov hlau ntws zoo li qub.
(6) Deformation degree. Yog tias qhov degree ntawm deformation loj dhau los yog me me, cov hlau ntws tsis sib xws. Tsim cov txheej txheem ntawm titanium rods thiab titanium alloy tuav nyob rau hauv kub extrusion
