锅炉用钢的性能可以通过“钢的合金化”来实现,要达到预期性能,应对钢实施热处理工艺。钢在加热和冷却过程中会发生组织结构的变化。加热后保温时间的长短和随后冷却速度的高低,也会影响组织结构的转变。使钢质本身组织结构的变化改变了钢的性能。钢的热处理就是对钢施以不同的加热、保温和冷却来获得所需要性能的一种工艺。锅炉用钢常用的热处理工艺有正火、淬火、固熔回火热处理,还有锅炉用钢经焊接后的消除应力热处理 (1)钢的正火
The performance of boiler steel can be achieved by “alloying of steel”. In order to achieve the expected performance, the steel should be heat treated. Steel changes in the structure of the structure during heating and cooling. After heating the length of the holding time and the subsequent cooling rate, will also affect the organizational structure changes. So that changes in the organizational structure of the steel itself has changed the performance of steel. Heat treatment of steel is a process of applying different heat, heat and cooling to the steel to achieve the desired properties. Boiler steel commonly used heat treatment process are normalizing, quenching, solid melt tempering heat treatment, as well as boiler steel after welding stress relief heat treatment (1) normalizing steel
