Much equipment in the metallurgical industry was based on Japanese designs of the 1930s and Soviet designs of the 1950s. Twothirds of the major equipment at Anshan, one of the largest plants in China, was built during the 1930s and 1950s. In general, major metallurgical equipment was more technologically advanced than instruments and control systems. Measuring and monitoring instruments, essential to quality control, were in short supply.
Most of the iron- and steel-making equipment in general use was domestically produced. This included blast furnaces based on Chinese improvements to old Soviet designs, ore-beneficiation plants, open-hearth furnaces, sideblown converters, electric furnaces, and a wide range of steel-finishing equipment. To achieve a higher technological level, various pieces of equipment were imported since China had not assimilated the technology necessary for domestic production. In most instances the industry imported only the main equipment, neglecting necessary control instruments and auxiliary technologies.
