Those principles should be followed when preparing special mud for refractory bricks

(1) Before laying refractory bricks, various refractory slurries should be pre-experimented and pre-built to determine the bonding time, initial setting time, consistency and water consumption of different slurries;

(2) Different equipment should be used to prepare different mud and cleaned in time;

(3) Clean water should be used when preparing the different quality slurries of refractory bricks, the amount of water should be accurately weighed, the mixing should be uniform, and it can be used as needed. The hydraulic and air-hardening mud that has been prepared must not be used with water, and the mud that has been initially set must not be used;

(4) When preparing phosphate-bound mud, ensure the specified trapping time, and adjust as needed. The prepared mud shall not be diluted with water at will. Due to its corrosive nature, this mud must not be in direct contact with the metal shell.
