Serbuk permukaan logam menyembur proses pemprosesan depan barisan pengeluaran adalah seperti berikut:
(1) Pra -proses pra -pelapisan salutan shell dispenser airMencuci air panas (30-an, 50-65 ° C) → Pra-Dipper (60s, 50-65 ° C) → Kulit (150s, 50-65 ° C) → Mencuci 1 (baris langsung) → basuh 1 [30-an, bilik suhu (rt)] → → → → basuh 2 (30s, rt) → air tawar suntikan langsung → menonton (30s, rt) → fosforusisasi (150s, 50-60 ℃) → mencuci 3 (30s, rt) → mencuci 4 ( 30S, RT) → Semburan langsung dan tulen.
(2) Pra -proses proses penyaman udara salutan shell
Mencuci air panas (40s, 50-65 ° C) → Pre -dipper (80s, 50-65 ° C) → Kulit (120s, 50-65 ° C) → Mencuci 1 (45s, Rt) → Mencuci 2 (50s, Rt) → suntikan langsung air tawar → Jadual (45s, rt) → fosforus (150 -an, 38 ~ 45 ℃) → mencuci 3 (45s, rt) → mencuci 4 (50s, rt) → basuh tulen (50s, rt) → Air tulen lurus lurus lurus lurus lurus lurus.
(3) proses pra -perapian khas
Fosforus disiplin (90 -an, 120 ~ 140 ℃) → Mencuci 1 (60s, 120 ~ 140 ℃) → semburan air tulen (5s, rt) → dibasuh 2 (60s, rt) → semburan air tulen (5s, rt)
