环保型糖类碳结合含碳氧化物-非氧化物复相耐火材料的基础研究

In order to solve the current problem of environment pollution and human health damage due to the phenolic resin and coal tar pitch binder used in carbon-containing refractory composites, this project is to develop a new environment friendly saccharides carbon binder using organic sugar (such as glucose, sucrose and starch) as raw materials, and prepare high-performance carbon-containing oxide - non-oxide refractory composites bonded with saccharides carbon binder and study the preparation technology of high-performance carbon-containing refractory composites. The main research contents include the effect of sugars (glucose, sucrose and starch) ratio, added water and curing parameters on the strength, discussing the carbonation process and carbonization mechanism of saccharides carbon binder, and research its oxidation kinetics. The effect of different saccharides carbon binders and process parameters on high-temperature strength contribution, the slag resistance behavior to steelmaking slag and blast furnace slag of carbon-containing refractory composites was studied, discussing the mechanism of high temperature strength gain and in-situ reinforcement. Finally, form a preparation technology of environment friendly high performance carbon-containing refractory composites with saccharides carbon-containing binder. This study lays an important theoretical foundation for the technical progress of environment friendly high-performance carbon-containing refractory composites, and is of great significance to the technologies processes of ferrous metallurgy and the development of environment friendly refractories.
