一、前言电站锅炉及汽轮机发电机组在燃烧重油和煤的情况下,易生成腐蚀性强的灰分,同时由于经常接触高温高压的蒸汽,所以要求具有耐腐蚀性好、高温强度高、特别是蠕变强度高的材料。本文介绍锅炉和汽轮机用的材料概况,低合金钢的焊接材料及焊接方法。 I. Introduction Power station boilers and turbine generating sets are prone to produce highly corrosive ash when they are burned with heavy oil and coal. At the same time, they are required to have good corrosion resistance, high temperature strength and high strength, particularly creep Variable strength of the material. This article describes the materials used in boilers and steam turbines, welding materials and welding methods for low-alloy steels.
