(1) High-qib slices
Cov khoom tseem ceeb ntawm qib high-grade scrap aluminium slices yog cam khwb cia aluminium alloy, alloy aluminium, ntshiab aluminium, thiab lwm yam. Ntawm lawv, muaj ntau qib ntawm thawj ob, thiab nws yog ib qho nyuaj rau kev faib los ntawm qib. Cov av, thiab lwm yam, tuaj yeem ncaj qha smelted rau hauv lub qhov cub. Hauv kev lag luam me me me me, xws li cov khoom siv txhuas yuav tsum tau muab faib ua cov ntawv txhuas txhuas, cov txhuas txhuas thiab cov ntshiab txhuas, thiab tom qab ntawd siv nyias.
(2) Qib qis qis
Rau qib qis slicing thiab incinerated shredded aluminium seem (tom kawg yog feem ntau tsis siv nyob rau hauv loj recycled txhuas nroj tsuag), nws yog tsim nyog los nqa tawm ntau complex sorting, vim hais tias ntawm nws tsis tshua muaj complex muaj pes tsawg leeg, ntxiv rau seem txhuas, nws kuj muaj. cov khoom siv hlau, cov tooj liab, cov khoom siv hlau xws li txhuas, thiab lwm yam pov tseg. Kev faib cov khoom pov tseg no feem ntau yog phau ntawv. Ua ntej, cov av thiab cov khib nyiab raug tshuaj xyuas, thiab tom qab ntawd muab cais los ntawm tes. Feem ntau ntawm phau ntawv sorting yog nqa tawm ntawm lub rooj ua haujlwm, feem ntau yog nyob ntawm kev tshuaj xyuas qhov muag thiab kev paub ntawm cov neeg ua haujlwm. Ua ntej, cov khoom tsis yog xim hlau raug txheeb, thiab tom qab ntawd cov khoom seem yog txheeb. Ntawm lawv, kev xaiv ntawm cov seem tooj liab thiab cov khoom siv ntshiab aluminium yog tshwj xeeb yog ceev faj. Txhawm rau ua kom tus nqi tso zis ntau ntxiv, cov khoom siv ntshiab aluminium xws li seem txhuas hlau, thiab lwm yam, yog cov khoom siv raw rau kev kho cov muaj pes tsawg leeg hauv kev ua kom cov txhuas siv dua tshiab. Qhov sib cais aluminium seem yog tov thiab feem ntau tsis subdivided.
Tam sim no, pretreatment ntawm cov khoom pov tseg hauv tsev tsis tau siv tshuab thiab automated, feem ntau yog cia siab rau kev ua haujlwm pheej yig. Cov cuab yeej siv yog hlau nplaum thiab steel foils. Raws li kev paub dhau los, qhov kev txheeb xyuas no muaj kev ua haujlwm tsawg, tsis zoo thiab tus nqi siab. Tsis tas li ntawd, feem ntau ntawm cov khoom seem uas tsis yog-ferrous hlau xws li tooj liab hauv cov khoom seem txhuas yog cov qias neeg, thiab kev txheeb xyuas phau ntawv yog qhov nyuaj, uas nyob deb tom qab. Nws yog ib qho tsim nyog los tshawb fawb thiab txhawb nqa cov khoom pov tseg aluminium pretreatment technology.
