Yuav ua li cas kom tsis txhob kub khiav shear overheating ntawm Melt

Nyob rau hauv kub khiav kev txhaj tshuaj molding, yaj shear overheating yog ib qho teeb meem zoo undetectable. Vim muaj kev sib txhuam shear hnyav thaum lub sij hawm siab - khiav ceev, cov yas yaj ua rau qhov kub thiab txias tam sim ntawd uas siab tshaj qhov kub txheej txheem. Qhov no ua rau cov khoom siv hauv zos decomposition, discoloration, thiab poob rau hauv kev ua tau zoo, uas yuav tsum tau tswj los ntawm combining kub tswj thiab txheej txheem optimization.

Optimize lub smoothness ntawm kub khiav lub internal ntws channel ua ntej. Polish cov phab ntsa sab hauv ntawm cov dej ntws tsis tu ncua kom nws du thiab tsis muaj burrs thiab carbon deposition, txo cov℃ntawm kev sib txhuam thiab ndlwg tsis kam raws li yaj mus, thiab txo qhov tsim ntawm shear tshav kub. Tsim cov kev khiav dej num hloov pauv radian sensibly los tiv thaiv txoj cai - lub kaum sab xis tuag, uas tuaj yeem ua rau muaj kev kub ntxhov extrusion thiab yaj shearing.

Qhov thib ob, phim qhov kub thiab txias ntawm tus khiav kub hauv qhov tsim nyog. Txo qhov kub ntawm lub hauv paus ntawm cov yaj, muab tso rau qhov kub thiab txias qhov chaw rau shear instantaneous kub nce, thiab tsim nyog txo qis manifold puag kub nyob rau hauv qhov kev nyab xeeb ntawm raw cov ntaub ntawv. Pab nrog ntau-point thermocouple tiag- lub sij hawm saib xyuas kom lav tias tag nrho qhov kub thiab txias yuav tsis siab dhau.

Thib peb, ua kom qhov siab tshaj plaws ntawm kev faib cov dej ntws thiab kev txhaj tshuaj nrawm. Tsis txhob siv sijhawm ntev ntawm kev txhaj tshuaj ultrahigh uniform ceev. Txo cov kev sib txhuam muaj zog shear, tswj qhov kub thiab txias tam sim no nyob rau hauv qhov chaw nyab xeeb ntawm cov ntaub ntawv, siv segmented ceev hloov kho, thiab txo qis tus nqi ntws ntawm nqaim ntws thiab qhov rooj qhov chaw.

Plaub, tswj lub sijhawm nyob ntawm cov ntaub ntawv kub khiav. Lub yaj lub thermal stability yuav ploj zuj zus los ntawm lub sijhawm khaws cia ntev, ua rau nws muaj kev cuam tshuam rau shear tshav kub thiab ua kom yooj yim deterioration. Txhawm rau kom ntseeg tau tias cov yaj tshiab yog tas li ncig thaum lub sijhawm tsim khoom sib cuam tshuam, tsim cov txheej txheem tawm ntawm cov khoom siv.

Tsis tas li ntawd, tsis txhob kub siab thiab kub nce siab los ntawm kev xaiv kub khiav tshwj xeeb alloy txaus channel cov ntaub ntawv uas muaj zog thermal conductivity thiab tam sim ntawd tshem tawm hauv zos shear sau cov cua sov. Melt shear overheating tuaj yeem tiv thaiv tau zoo thiab kev tsim cov khoom zoo thiab lub cev ntawm cov khoom yas tuaj yeem lav tau tag nrho los ntawm kev sib koom ua ke kev ua kom zoo dua qub, kev tswj qhov kub thiab txias, thiab cov txheej txheem sib txuam.
