What are the steps required for the preparation of refractory brick slurry?
1. Clean water should be used to prepare different quality muds, the amount of water must be accurately weighed, the mixing must be uniform, and used as soon as the adjustments are made. The hydraulic and air-hardened muds that have been prepared must not be used with water, and the mud that has been set must not be used.
2. When preparing the phosphate-bound mud, ensure the specified trapping time, and adjust it as you use it. The prepared mud shall not be diluted with water arbitrarily. This mud is corrosive and must not be in direct contact with the metal shell.
3. Before bricklaying, 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.
4. Different equipment should be used to prepare different mud and cleaned in time.
