摘要
在实验室研究基础上提出一种经济型耐火钢成分设计，研究结果表明：具有细小多边形铁素体＋珠光体＋粒状贝氏体混合组织的该钢种具有良好的高温力学性能、良好的低温韧性，满足了建筑用耐火钢的性能要求。
The compositional design of economical fire-resistant steel is studied in this paper. The experimental results show that the steel,with a combination of polygonal ferrite, pearlite and granular banite, has good high-temperature mechanical properties, superior properties of low temperature toughness, meeting the requirements in properties for fire resistant constructional steel.
