Lub thermal conductivity ntawm titanium pas nrig thiab titanium alloy pas nrig billet yog tsawg, uas yuav tsim ib tug zoo kub sib txawv ntawm lub nto txheej thiab lub puab txheej thaum thermal extrusion. Thaum qhov kub thiab txias ntawm lub tog raj kheej extrusion yog 400 degrees, qhov kub sib txawv tuaj yeem ncav cuag 200 ~ 250 degrees.Nyob rau hauv lub tshuab nqus tsev thiab cov seem seem nyob rau hauv qhov kev cuam tshuam ntawm qhov kub thiab txias sib txawv, billet nto thiab qhov nruab nrab ntawm cov hlau tsim muaj zog sib txawv thiab yas khoom, nyob rau hauv cov txheej txheem extrusion yuav ua rau ib tug heev uneven deformation, nyob rau hauv lub nto txheej, ua lub hauv paus ntawm ntxiv tensile kev nyuaj siab tawg thiab tawg rau saum npoo ntawm cov khoom extrusion.The thermal extrusion txheej txheem ntawm titanium pas nrig thiab titanium alloy pas nrig khoom. Nws yog qhov nyuaj tshaj li ntawm aluminium alloy, tooj liab alloy, thiab txawm hlau, uas yog txiav txim siab los ntawm lub cev tshwj xeeb thiab tshuaj lom neeg ntawm titanium pas nrig thiab titanium alloy pas nrig.
Txoj kev kawm dynamics kawm ntawm industrial titanium alloy hlau qhia tau hais tias muaj ntau qhov sib txawv ntawm cov hlau ntws tus cwj pwm nyob rau hauv qhov kub thiab txias cheeb tsam sib xws rau cov theem sib txawv ntawm txhua lub alloy.Yog li ntawd, ib qho ntawm cov ntsiab lus tseem ceeb cuam tshuam rau extrusion flow yam ntxwv ntawm titanium pas nrig thiab titanium alloy pas nrig yog billet cua sov kub ntawm cov hlau theem hloov lub xeev.Tub extrusion nyob rau hauv lub a los yog ib tug ntxiv P theem cheeb tsam ntws ntau uniformly piv rau kub extrusion nyob rau hauv lub p-theem cheeb tsam.Nws yog heev nyuaj rau extruded khoom kom tau ib tug Qhov zoo ntawm qhov chaw nyob deb, cov txheej txheem extrusion ntawm titanium alloy pas nrig yuav tsum siv cov roj nplua nyeem.Qhov laj thawj yog vim li cas: titanium ntawm 980 degrees thiab 1030 degrees kub, yuav tsim ib lub molten co-crystal nrog hlau los yog npib tsib xee-raws li alloy pwm. cov ntaub ntawv, thiaj li hais tias cov tuag muaj zog hnav tawm.
Yam tseem ceeb cuam tshuam rau cov hlau ntws thaum extrusion:
(1) Extrusion method.Reverse extrusion flows evenly than forward extrusion metal, txias extrusion dua kub extrusion hlau, thiab lubrication extrusion tshaj unlubricating extrusion hlau.Cov nyhuv ntawm extrusion txoj kev yog tiav los ntawm kev hloov ntawm kev sib txhuam tej yam kev mob.
(2) Extrusion ceev.Qhov extrusion tshaj tawm nce, thiab inhomogeneity ntawm cov hlau ntws nce.
(3) Extrusion kub.Qhov tsis sib xws ntawm cov hlau nce thaum extrusion kub nce thiab deformation tsis kam ntawm cov billet txo. Thaum lub sij hawm extrusion txheej txheem, yog hais tias qhov kub ntawm lub extrusion lub tog raj kheej thiab cov pwm yog tsawg heev, thiab cov hlau. Qhov kub ntawm qhov sib txawv ntawm txheej txheej thiab lub hauv paus txheej yog loj, ces lub nonuniformity ntawm cov hlau ntws nce.Qhov zoo dua cov thermal conductivity ntawm cov hlau, qhov ntau uniform kub tis ntawm lub ingot kawg nto.
(4) Lub zog hlau.Thaum lwm yam xwm txheej zoo ib yam, qhov siab dua cov hlau muaj zog, qhov sib txawv ntawm cov hlau ntau dua.
(5) Hloov lub kaum sab xis.Qhov loj dua lub kaum sab xis tuag (lub kaum sab xis ntawm qhov tuag kawg ntawm qhov chaw thiab lub hauv paus axis), qhov tsis sib xws ntawm cov hlau fluidity yog ntau dua.Thaum cov ntxeem tau pwm extrusion yog siv, cov pwm qhov yog txheej txheem tsim nyog, thiab cov hlau ntws zoo li qub.
(6) Deformation degree.Qhov deformation degree loj dhau los yog me me, thiab cov hlau ntws tsis sib xws.
Raws li ib qho ntawm Tuam Tshoj porous titanium ntawv thiab lim manufacturers thiab lwm tus neeg, TopTi Tech muaj peev xwm muab koj cov khoom zoo titanium, npib tsib xee, ntxeem tau titanium phaj los yog ntawv, sintered titanium pas nrig lim thiab hais txog, yog tias koj txaus siab rau ib qho ntawm nws, Zoo siab txais tos hu rau peb.
