Embodiment 1
[0023] Such as figure 1 As shown, the forsterite four-layer composite brick of this embodiment is stacked with a heavy working layer 1 , a first transition layer 2 , a second transition layer 3 , and a light heat insulation layer 4 sequentially from bottom to top.
[0024] in:
[0025] The particle gradation and mass percentage of the raw materials used in the heavy working layer 1 are as follows: forsterite with a particle size of 1 to 3 mm: 45%; forsterite with a particle size of less than 1 mm and larger than 325 mesh: 25%; 325 mesh forsterite: 5%; 325 mesh sintered magnesium powder: 4%; 325 mesh silica: 21%. The binding agent that adopts when preparing materials is industrial lignosulfonate solution, and its weight is 4% of heavy working layer weight.
[0026] The gradation and mass percentage of raw material particles used in the first transition layer 2 are: sintered magnesia with a particle size of 1 to 3 mm; 45%; sintered magnesia with a particle size not greater tha...
