Microcrystalline graphite powder for carbonic refractory material and preparing method of microcrystalline graphite powder
The invention discloses microcrystalline graphite powder for a carbonic refractory material and a preparing method of the microcrystalline graphite powder. The preparing method comprises the preparing steps that firstly, 5-35wt% of phenolic resin is dissolved into 10-35wt% of alcohol, 40-80wt% of microcrystalline graphite is added, magnetic stirring is conducted for 2-10 minutes, and paste is obtained; secondly, the paste is put into an oven to be processed for 8-24 hours at the medium and low temperature, and a cured product is obtained after cooling; thirdly, the cured product is subjected to ball milling and then passes through a 325-mesh screen, and ball-milled powder is obtained; fourthly, the ball-milled powder is subjected to high-temperature carbonization for 1-4 hours under the condition of isolated air, and the microcrystalline graphite powder for the carbonic refractory material is obtained after cooling. The microcrystalline graphite powder is simple in technology and low in cost, the utilization rate of the microcrystalline graphite is increased, the added value of the product is increased, and the dilemma of resource exhaustion of crystalline flake graphite is relieved; in addition, the carbonic refractory material produced through the microcrystalline graphite powder prepared through the method has the good thermal shock stability and slag corrosion resisting performance, and can meet the use requirement.
