Abstract
The present invention relates to a method for manufacturing high-strength haycite supporting agents. In the method, 100 parts by weight of soft burning bauxite as base materials which is added with the following adjuvant materials: 2 to 15 parts of clay soil, 1 to 10 parts of lanthanide series oxides, 0.3 to 3 parts of manganese dioxide and 0.1 to 3 parts of magnesium oxide, and the base materials and the adjuvant materials are mixed and milled into fine powder which is added with water for looseness and then is manufactured into granules in a balling machine. The granules are sent into a kiln at 1100 to 1500 DEG C of sintering temperature for a sintering time from 0.5 to 5 hours and are burnt into finished products. The compressive strength of products manufactured by the present invention achieves above 69Mpa, and the breaking rate of the finished products is less than and equal to 10%; the capacity of flow diversion can reach 54.8 micrometers <2> /centimeter. The present invention has the characteristics of high compressive strength of the finished products, good sphericity, simple technology and low manufacture cost, and can be used for the production of haydite supporting agents.
Description
Technical field
