Embodiment 1
[0046] The preparation method of the honeycomb ceramic-metal composite vertical mill roller, its specific steps are as follows:
[0047] Step 1. Preparation of honeycomb porous ceramic prefabricated body: First, mix ceramic particles, pore-forming agent and binder at a ratio of 100:3:15 and add them evenly into the mold to prepare a honeycomb porous prefabricated body, then raise the temperature to 500°C for 2 hours The pore-forming agent in the porous ceramic preform is exerted to obtain a honeycomb porous ceramic preform, and the structure diagram of the honeycomb porous ceramic preform is as follows image 3 Shown; wherein the ceramic particles are zirconium corundum, the particle size is 2mm; the pore-forming agent is polyoxymethylene, the particle size is 0.5mm; the binder is a mixture of aluminate cement and silica sol with a mass ratio of 5:10;
