preparation example Construction
[0033] A method for preparing a high-tech material for needle coke rotary kiln lining, comprising the following steps: (1) adding a certain amount of aggregate, fine powder material, and superfine powder to a mixing equipment in sequence according to parts by weight, and mixing uniformly; 2) Add the admixture to the kneading equipment, fully stir and mix evenly to obtain the finished product; (3) testing; (4) packing.
[0034] The detection method is as follows: add the finished product obtained in step (2) into the mold to make a sample block with a length, width and height of 160mm×40mm×40mm, let it stand for 24 hours, demould, and then keep it for three days and then place it in a 110°C refrigerator. Dry in an oven for 24 hours to prepare a sample, and test the compressive strength, bulk density, flexural strength, and linear change rate of the sample.
