Thermal conductivity ntawm cov khoomtitanium pas nrigyog qhov tsawg, thiab qhov kub sib txawv ntawm cov txheej txheej saum npoo thiab cov txheej sab hauv yuav loj thaum lub sij hawm kub extrusion. Thaum qhov kub ntawm lub tog raj kheej extrusion yog 400 degree, qhov kub sib txawv tuaj yeem ncav cuag 200 ~ 250 degree. Nyob rau hauv kev sib xyaw ua ke ntawm suction ntxiv dag zog thiab qhov kub ntawm qhov sib txawv ntawm qhov seem, cov hlau ntawm qhov chaw thiab qhov nruab nrab ntawm cov billet muaj qhov sib txawv ntawm lub zog thiab cov yas, uas yuav ua rau tsis sib xws heev thaum lub sij hawm extrusion txheej txheem, thiab tsim ib tug loj. ntxiv tensile quab yuam ntawm txheej txheej. Kev ntxhov siab dhau los ua qhov chaw ntawm cov kab nrib pleb thiab cov kab nrib pleb ntawm cov khoom extruded. Cov txheej txheem kub extrusion ntawm titanium pas nrig thiab titanium alloy pas nrig cov khoom yog qhov nyuaj tshaj li ntawm aluminium alloy, tooj liab alloy thiab txawm hlau, uas yog txiav txim los ntawm tshwj xeeb lub cev thiab tshuaj zog ntawm titanium pas nrig thiab titanium alloy pas nrig.
Cov kev tshawb fawb ntawm cov hlau ntws dynamics ntawm industrial titanium alloys qhia tau hais tias muaj ntau qhov sib txawv ntawm cov hlau ntws tus cwj pwm ntawm cov alloys sib txawv hauv cov cheeb tsam kub. Yog li ntawd, ib qho ntawm cov ntsiab lus tseem ceeb cuam tshuam rau extrusion ntws yam ntxwv ntawm titanium rods thiab titanium alloy rods yog cov cua kub kub ntawm lub billet uas txiav txim siab lub xeev ntawm hlau transformation. Piv nrog rau qhov kub thiab txias extrusion ntawm P-theem cheeb tsam, cov hlau ntws nyob rau hauv ib-theem cheeb tsam los yog P-theem cheeb tsam yog ntau uniform. Nws yog qhov nyuaj kom tau txais cov khoom extruded nrog cov khoom zoo. Txog rau tam sim no, lub extrusion ntawm titanium alloy tuav yuav tsum tau siv lubricants. Lub ntsiab yog vim li cas titanium yuav tsim eutectic nrog hlau-raws li los yog npib tsib xee-raws li alloy pwm cov ntaub ntawv ntawm 980 degrees thiab 1030 degrees, uas yuav ua rau muaj zog pwm hnav.
Lub ntsiab yam tseem ceeb cuam tshuam cov hlau ntws thaum extrusion:
(1) Extrusion txoj kev. Cov hlau ntws ntawm thim rov qab extrusion yog zoo ib yam tshaj li rau pem hauv ntej extrusion, txias extrusion yog ntau uniform dua kub extrusion, thiab lubricated extrusion yog ntau uniform dua tsis-lubricated extrusion. Cov nyhuv ntawm txoj kev extrusion yog ua tiav los ntawm kev hloov cov kev sib txhuam.
(2) Extrusion ceev. Lub inhomogeneity ntawm hlau ndlwg intensifies nrog lub nce ntawm extrusion ceev.
(3) Extrusion kub. Thaum lub extrusion kub nce thiab deformation tsis kam ntawm lub billet txo, qhov tsis sib xws ntawm cov hlau intensifies. Thaum lub sij hawm extrusion txheej txheem, yog hais tias qhov kub thiab txias ntawm extrusion chim thiab tuag yog tsawg heev, qhov kub ntawm qhov sib txawv ntawm txheej txheej thiab qhov nruab nrab txheej yog loj, thiab qhov tsis sib xws ntawm cov hlau ntws yuav nce. Qhov zoo dua qhov thermal conductivity ntawm cov hlau, qhov sib txawv ntawm qhov kub thiab txias ntawm qhov kawg ntawm lub ingot.
(4) Hlau zog. Thaum lwm yam sib npaug, cov hlau muaj zog dua, cov hlau ntws ntau dua.
(5) Lub kaum sab xis tuag. Lub kaum sab xis loj dua (piv txwv li lub kaum sab xis ntawm lub ntsej muag tuag thiab lub hauv paus axis), qhov tsis sib xws ntawm cov hlau ntws ntau dua. Thaum extruding nrog ib tug ntxeem tau tuag, lub qhov tuag yog teem kom tsim nyog thiab cov hlau txaus nyiam mus ua ib yam.
(6) Qib deformation. Yog hais tias qhov degree ntawm deformation loj dhau los yog me me, cov hlau ntws tsis sib xws.
