style="text-indent:25px">高錳酸鉀氧化容量法在硫酸磷酸混合酸介質(zhì)中，用高錳酸鉀氧化釩以亞硝酸鈉還原，用硫酸亞鐵銨標準溶液滴定測量釩的含量。測定合金圓鋼中含鉻量的方法主要有過硫酸銨銀鹽容量法、二苯卡巴阱比色法、二甲苯橙法、電位或目視滴定法、高錳酸鉀滴定法、火焰原子吸收光譜法等。一般低合金鋼常采用二苯卡巴阱比色法，高合金鋼常采用容量法。測量合金圓鋼中錳含世的方法有亞砷酸鈉-亞硝酸鈉容14法(過硫酸鐵容量法)、磷酸-三價錳容量法、過硫酸銨比色法、過碘酸鹽比色法、高氣酸法、火焰原子吸收光譜法、電位滴定法、電流滴定法、高錳酸鉀滴定法等。其中容量法是測定鋼中含錳量較常用方法?！?/p><p style="text-indent:25px">合金圓鋼酸洗鈍化的制作知識：鋼鐵零件一般在10％～20％(體積)硫酸溶液中酸洗，溫度為40℃。當溶液中含鐵量超過80g/L，硫酸亞鐵超過215g/L時，應(yīng)更換酸洗液。常溫下，用20％～80％(體積)的鹽酸溶液對鋼鐵進行酸洗，不易發(fā)生過腐蝕和氫脆現(xiàn)象。由于酸對金屬的腐蝕作用很大，需要添加緩蝕劑。清洗后金屬表面成銀白色，同時鈍化表面，提高合金抗腐蝕能力。為了清掉硅藻土載體表面吸附，減少色譜峰拖尾，載體在使用前需進行酸洗或堿洗處理。圓鋼分為熱軋、鍛制和冷拉三種。</p><div
