摘　　要：经（Al＋siCa合金十REMg合金）复合变质处理、固深处理或锻造加固溶处理，能提高退火炉构件用ZGOCr23Ni13热强钢的纯净度，改善夹杂物形态和分布，消除铸态组织中的网状脆性相，有利于提高钢的韧性，从而提高了炉用构件的使用寿命．Furnace components for anneal is made of ZGoC23Ni13 bot strength steel. After compound inocula-tion (Al+SiCa alloy+REMg alloy),solution heat treating or forging and solution heat treating,the purity is raisedand the shape and distribution of impurities are much improved,the net embtittlement phases in cast matrix are elimi-nated. This operation provides for the best combination of toughness and long service life of the steel.
