The modulation principle of mud when using refractory bricks

Modulation for bricklaying refractory mortar shall comply with the following principles:

(1) before bricklaying to deal with all kinds of refractory mud of pre experiment and pre laying and determine the different mud bonding time, initial setting time, consistency and water;

(2) The modulation of different mud to use different apparatus, and timely cleaning;

(3) Different modulation to use clean water mud, water should be accurate weighing, to reconcile uniform, adjusted with the use. Has modulated the water is hard and hard and fast and hard mud and water use, has been the beginning of the mud cannot continue to use;

(4) Modulation phosphate bonded slurry to ensure that the provisions of the trapped material time and in tune with the, the slurry has a good modulation may not be any diluted with water. This kind of mud is corrosive and may not be in direct contact with the metal shell.
