On December 11th, China Association of Construction Enterprise Management (CACEM) held 2020 Engineering Construction Science and Technology Award Conference in Beijing. The achievement of "The Key Technology and Industrialization of Silica-sol Bonded Amorphous Refractories", jointly completed by CFMCC, Wuhan Metallurgical Construction Research Co. Ltd and Wuhan University of Science and Technology, won the first prize of Science and Technology Progress Award.

As the major special program in the field of “Steel & Metallurgy ”for MCC during the “Third Five-Year plan”period, “the key technology and industrialization of silica-sol bonded amorphous refractories”, through 10 years of R&D and innovation, has developed monolithic refractories series products and furnace hot on-line repairing packaged technology by means of a new silicon sol binding system. It has resolved defects of the monolithic refractories in high-temperature industrial furnace with the traditional binding system, significantly prolonged the service life of furnaces, broken the foreign enterprises monopoly of similar products in China, and reduced the operation cost of enterprises as well.

This achievement has got 7 authorized invention patents, issued 2 industry standards, obtained 3 construction methods at provincial and ministerial level, and published 14 academic papers in domestic and foreign core journals. Upon evaluation by the Achievement Appraisal Committee of MCC, the technology and the main technical indicators of the products have reached the international advanced level. This technology has been popularized and applied in blast furnaces, hot stove furnaces, lime-kilns and heating furnaces of large iron and steel enterprises at home and abroad, such as 5800m3 blast furnaces in Shagang Group and 5100m3 blast furnaces of Shandong Steel, and etc. It has achieved great economic and social benefits in prolonging the service life of industrial kilns, saving industrial resources and reducing pollution and emission.
