Embodiment 1
[0021] A preparation method of composite aluminum-chrome brick: its specific preparation steps are as follows:
[0022] S1. Preparation of mullite powder: put the mullite into a pulverizer for preliminary crushing, and pulverize into mullite particles, the particle size of the pulverized mullite particles is 50 mesh, and then put the mullite particles into a roasting furnace Carry out high-temperature roasting, and the temperature inside the roasting furnace is controlled at 1700 degrees Celsius. After the roasting is completed, the mullite particles are taken out, and when it is lowered to room temperature, take half of the mullite particles and put them into the Raymond machine Grinding, grinding mullite particles into mullite dust, the particle size of the mullite is 200 mesh, then pouring the ground powder into pure water for cleaning, and then drying it with a vacuum spray dryer Made into mullite powder;
