鑄造(zao)煙氣污染物的來(lai)源

目前,常用的壓(ya)(ya)(ya)鑄工藝有熱室(shi)壓(ya)(ya)(ya)鑄和(he)冷(leng)室(shi)壓(ya)(ya)(ya)鑄.冷(leng)室(shi)壓(ya)(ya)(ya)鑄以液態金(jin)屬(shu)(shu)為原料,噴身進入模具(ju)壓(ya)(ya)(ya)鑄成(cheng)型,模具(ju)壁由循(xun)環(huan)冷(leng)卻(que)水冷(leng)卻(que).熱室(shi)壓(ya)(ya)(ya)鑄是將(jiang)金(jin)屬(shu)(shu)切屑成(cheng)粉狀,經預(yu)加熱后注入模具(ju)壓(ya)(ya)(ya)鑄成(cheng)型,預(yu)加熱和(he)模具(ju)加熱一般采用電(dian)加熱.在壓(ya)(ya)(ya)鑄生產的過程中,會產生煙(yan)氣,熱量(liang),粉塵等(deng),這(zhe)些廢氣和(he)煙(yan)塵中含(han)有各種金(jin)屬(shu)(shu)氧化物(wu)和(he)非(fei)金(jin)屬(shu)(shu)氧化物(wu),同時還可(ke)能含(han)有有害(hai)物(wu)質,這(zhe)些都可(ke)能對環(huan)境產生污染.
