1 概述随着经济的不断发展,各行各业对中厚钢板的性能及质量要求越来越高,特别是与人民生活及生产、安全密切相关的各种锅炉用板、压力容器用板等中厚板的内在质量,标准中严格规定了不准存在分层、夹杂等钢板内部缺陷。冶金部还实行了锅炉板、压力容器板生产许可证制度。为保证和提高锅炉板、压力容器板等专用中厚板的质量,各厂在原料精选、冶炼工艺优化及控制,如:低硫磷铁水
1 Overview With the continuous development of economy, all walks of life on the performance of medium and thick steel plates and quality requirements are getting higher and higher, especially with the people’s lives and production, safety is closely related to various boiler plates, pressure vessel plates Thickness of the internal quality of the standard strict rules are not allowed stratification, inclusions and other internal steel plate defects. Ministry of Metallurgical also implemented a boiler plate, pressure plate production license system. In order to ensure and enhance the quality of boiler plate, pressure vessel plate and other special plate, the plant in the selection of raw materials, smelting process optimization and control, such as:
