金属淬火新工艺 俄罗斯科学院机器研究所的专家发明了一种金属淬火新工艺,可使钢制机器零件和工具的使用寿命延长好几倍。 世界上许多科学家都在研究如何缩短金属淬火时间,因为淬火时间越短,金属硬度就越高。俄罗斯专家发明的这种新工艺 5-200mm厚的铸态带坯的连铸和直接轧制的实验室研究 一项对厚度为5—20mm铸态带坯中间加工阶段的基础研究已同将直接热轧应用于这类铸态带坯的可能性相联系起来。为这目的建造了一台均热炉和一台与现存热轧机相衔接的连铸机。这台连铸机设计为
New Process for Metal Quenching Experts at the Institute of Machinery of the Russian Academy of Sciences invented a new metal quenching process that can extend the service life of steel machine parts and tools several times. Many scientists in the world are studying how to shorten the metal quenching time because the shorter the quenching time, the higher the hardness of the metal. Russian experts invented this new technology 5-200mm thick cast billet continuous casting and direct rolling laboratory research a thickness of 5-20mm cast billet intermediate processing phase of the basic research has the same direct The potential for hot rolling to be applied to such as cast billets is linked. For this purpose a soaking furnace and a continuous casting machine connected to the existing hot rolling mill were built. This caster is designed as
