| 钢铁生产者 | steel producer (①This version of the L-D process is known as the LD-AC process, and has enabled steel producers to treat a much wider range of irons, produced from imported and indigenous ores. 这种 L-D 炼钢法的改进型称之为 LD-AC 炼钢法；炼钢生产者使用这种改进型炼钢法就能处理范围大的多的进口和本地矿石生产的铁水。② The experience of many years and the close cooperation between steel producers and consumers have led to the development of mold steels that can be divided into the following groups: nitriding steels, case-hardened steels, prehardening steels, fully hardening steels, corrosion-resistant steels and maraging steels. 依靠多年经验和钢厂与用户的密切合作，现已研发出的铸型用钢可分为以下类型：氮化钢、表面硬化钢、预硬化钢、全硬淬透钢、耐蚀钢以及马氏体时效钢等。) |
