Metallurgist and ceramist. Born in Jiangning, Jiangsu Province.Graduated from Jiangnan Institute of Education in 1910. Received MS from Conell University, USA in 1915. Director and research professor,Shanghai Institute of Metallurgy, Chinese Academy of Sciences.

As one of the pioneers in electric furnace steel making, Zhou built the first three-phase arc furnace in Chin in 1929 and produced different grades of stainless manganese and high-speed steels in this furnace. During the Anti-Japanese War, he founded the Chinese Electric Steel-Making Works at Kunming and served as the general manager and chief engineer of this firm. The chief task achieved by his firm was the fabrication of high-strength steel strands of heavyduty cables used for lifting brine buckets in Ziliujing, the principal salt supplier in the Southwestern China. In the early 1950s, he endeavored in manufacturing modular irons and extending their application in machinery. In the late 1950s, he established the prototype blastfurnace in Shanghai Institute of Metallurgy in order to study in delails the smelting processes for the rare-earth and fluoride containing Baotou iron ore and the V-Ti rich Panzhihua magnetite ore. His results laid a sound scientific foundation for the optimization of iron smelting processes for Baotou and Panzhihua ores. As a forerunner in ceramics,he showed great enthusiasm over ancient Chinese porcelain and zealously advocated the study of some lost glazing technology in ancient pottery.

He became Member of the Chinese Academy of Sciences in 1955.

Metallurgist and metal materials expert. Born in Dantu, Jiangsu Province. Graduated from Beijing University in 1923. Went to USA in 1924 for further study and received MS from Carnegie Institute of Technology and Ph.D. from Harvard University. Professor and advisor,Shanghai Jiaotong University.

Zhou devoted himself for a long time to the research on physical metallurgy and iron and steel smelting. In 1930, he sought and completed for the first time in China the large cast and forge pieces and accomplished the task for casting and processing the seat and abutment of Qiantang River Bridge. He was the first among the Chinese pioneers to manufacture tool steel, high speed steel and stainless steel.He developed and fabricated the crucible-smelting steel, produced smeltingly the first patch of Chinese high quality rapid steel, die steel,magnetic steel and stainless steel, and designed by himself the electric furnace to produce metal materials such as pure iron tungstate and silicon iron. After 1949, he developed and fabricated the ball bearings steel containing less or no nickel and chromium. In 1960, he first proposed the oxygen top-blow converter steel smelting process which was employed in the production in factories. He proposed the oxygen top-bottom double blow converter process in 1978.

He became Member of the Chinese Academy of Sciences in 1955.
