Precision Aluminium Automotive Parts Chaw tsim tshuaj paus hauv Baden-Württemberg, Lub teb chaws Yelemees

Cov neeg siv khoom Profile & Cov ntsiab lus ua haujlwm:
Qhov Tier no -1 tus neeg muag khoom rau German khoom kim heev automakers tsim cov aluminium complex -silicon alloy Cheebtsam, nrog rau cov cav blocks, lub tog raj kheej taub hau, thiab pistons rau siab - tsheb ua tau zoo. Lawv cov txheej txheem tsim khoom cia siab rau A356 thiab A319 aluminium alloys, uas yuav tsum tau muaj cov ntsiab lus ntawm silicon (feem ntau 7-12%) kom ua tiav qhov zoo tshaj plaws castability, hnav tsis kam, thiab thermal stability. Kev khiav hauj lwm lub roj teeb ntawm nruab nrab zaus induction rauv nrog ib tug niaj hnub throughput ntawm kwv yees li 120 tons ntawm molten txhuas, lub foundry ua hauj lwm pab raws li ib tug tseem ceeb txuas nyob rau hauv lub European automotive mov saw.

Qhov Kev Sib Tw Pib Pib & Cov Ntsiab Lus Kev Mob:
Cov chaw tsim khoom tau ntsib qhov tsis zoo tsis tu ncua uas cuam tshuam rau lawv tsuas yog - hauv - lub sijhawm xa khoom cog lus rau ntau lub tsheb OEMs. Cov kev sib tw tshwj xeeb suav nrog:

Silicon Recovery Variability:Cov hlau silicon uas lawv tau nrhiav tau nthuav tawm tus cwj pwm tsis sib haum xeeb, nrog cov nqi rov qab hloov pauv ntawm 82% thiab 91% hla cov khoom sib txawv. Qhov kev tsis txaus ntseeg no yuam cov neeg siv hlau ua haujlwm niaj hnub dhau los ua silicon lub hom phiaj thiab tom qab ntawd dilute nrog thawj aluminium, tsim kom tsis muaj txiaj ntsig.

Iron Contamination Issues:Periodic spikes nyob rau hauv cov ntsiab lus hlau (ntau tshaj 0.15% hauv cov hlau tiav) tau taug qab mus rau impurities hauv lawv cov khoom siv silicon hlau.
