一、快速加热所采用的设备工具钢的淬火多采用盐浴炉。我厂是采用单相内热式电极盐浴炉来加热,所以快速加热亦使用同样设备。盐浴炉的配盐成分:(1)70%BaCl_2+30%NaCl:适用于加热齿轮铣刀、可张大铰刀、镶片刀具刀体。(2)50%NaCl+50%KCl:适用于加热丝锥、板 First, the rapid heating equipment used by the steel quenching and more salt bath furnace. Our factory is using single-phase heat-type electrode salt bath furnace to heat, so fast heating also use the same equipment. Salt bath furnace with salt composition: (1) 70% BaCl_2 + 30% NaCl: Suitable for heating gear milling cutter, reamers, inserts knife body. (2) 50% NaCl + 50% KCl: Suitable for heating tap, plate
