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．
By (Al + siCa alloy ten REMg alloy) compound metamorphic treatment, solid processing or forging solution treatment, can improve the purity of the annealing furnace ZGOCr23Ni13 steel used to improve the morphology and distribution of inclusions, eliminate the network structure of as-cast Brittle phase, is conducive to improving the toughness of steel, thereby increasing the service life of furnace components.
