Abstract

The invention discloses a silicon carbide round pipe material and a preparation method thereof. The silicon carbide round pipe material is composed of 50-70 parts of silicon carbide rough material, 30-50 parts of silicon carbide fine material, 1.5-3 parts of cellulose, 7-10 parts of water solution and 0.2-0.5 part of glycerin. The silicon carbide round pipe material is simple in compositional structure and preparation process, so that cost can be saved when compared with existing silicon carbide round pipe materials. Improving of performance of the silicon carbide round pipe material can be promoted by adjusting proportion of silicon carbide coarse materials and silicon carbide fine materials, adding cellulose to improve adhesiveness of the whole formulation and adding glycerin to improvelubricating capacity and wetting capacity. Finally, through reasonable proportion and composition, the problem that steel pipes made of the silicon carbide round pipe material are low in strength anddensity can be solved, and utilization rate of the silicon carbide round pipe material is increased.

Description

technical field [0001] The invention relates to the technical field of engineering ceramics, in particular to a silicon carbide circular tube material and a preparation method thereof. Background technique [0002] Silicon carbide products are non-oxide ceramic materials made of silicon carbide (SiC), which have good wear resistance and corrosion resistance, high temperature strength, high thermal conductivity, small thermal expansion coefficient, and good thermal shock stability. very broad. For example: in steelmaking and ironmaking, it can be used in ladle lining, nozzle, plug, blast furnace bottom and bosh, tapping trough, converter and electric furnace tapping port, heating furnace without water cooling slide rail, etc. ;In the smelting of non-ferrous metals such as zinc, copper, aluminum, titanium, metal silicon, etc., it is widely used in electric furnace linings, stills, distillation tower trays, side walls of electrolytic cells, molten metal pipes, suction pumps an...
