Tub Ntxhais Dance: Alloy, Pwm, thiab lub qhov rais ntawm lub sijhawm
Lub plawv ntawm cov txheej txheem tsis yog lub tshuab txhaj tshuaj nws tus kheej; nws yog kev sib yuav ntawm cov khoom thiab pwm. Koj tsis ua haujlwm nrog polymers. Koj tab tom cuam tshuam nrog cov hlau uas mus los ntawm cov kua mus rau cov khoom nyob rau hauv ib qho tseem ceeb, nqaim qhov rais. Piv txwv li, nrog lub Nickel-raws li alloys peb feem ntau khiav ntawm peb qhov chaw, qhov superheat-qhov kub siab tshaj qhov dej taw tes-yog txhua yam. Siab dhau lawm, thiab koj erode cov hlau pwm (qhov tuag) los yog ua rau ntau dhau shrinkage porosity. Tsawg dhau, thiab koj tau txais ib qho misrun lossis txias laps ua ntej kab noj hniav txawm puv. Nws yog ib qho tactile. Koj kawm los txiav txim cov hlau viscosity los ntawm txoj kev nws nchuav los ntawm lub ladle, ib qho txuj ci tsis muaj phau ntawv qhia tau.
Qhov no yog qhov twg ntau xyoo ntawm kev paub dav dav, zoo li 30-xyoo keeb kwm peb muaj Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), yuav tsis-negotiable. Koj tsis tuaj yeem yuav lub tshuab thiab pib xwb. Koj xav tau qhov kev nkag siab zoo ntawm cov tsev neeg sib txawv ntawm cov hlau coj li cas. Tsiv ntawm casting stainless hlau Cheebtsam mus rau ib tug cobalt-raws li alloy rau ib tug high-hnav daim ntawv thov tsis yog ib tug yooj yim parameter hloov ntawm lub HMI screen. Tag nrho thermal tswj ntawm qhov tuag, lub rooj vag system tsim, txawm tias tus neeg sawv cev tso tawm, tej zaum yuav xav tau kev rov xav dua. Cov pwm tsis yog ib lub thawv passive; nws yog ib qho khoom siv hluav taws xob ua kom sov, thiab tsim nws cov cua txias yog kev kos duab ntau dua li kev tshawb fawb qee zaum.
