新型压力容器厚壁筒节热处理炉

摘要

针对大型厚壁压力容器筒节热处理加热时内、外壁温差大的问题,引入了“内加热”技术,研制了能对筒节的内壁和外壁同时加热的环型罩式电阻炉,对提高筒节的热处理加热质量的提高有重大意义.%Internal heating technology is introduced to deal with the problem of big temperature difference between the inner and outer walls when large thick-walled pressure vessels are performing heat treatment. A ring type bell electrical furnace that can simultaneously heat the inner and outer walls of a cylindrical shell section is developed, greatly improving the quality of the heat treatment of a cylindrical shell section.
