Circulating fluidized bed boiler refractory wear-resistant insulation material cyclone tube outlet flue physicochemical index

High strength castable

YG-TJ-13

Normal temperature flexural strength>10 Mpa；

Were resistance<8cc

Divided into three layers:

1. High-strength wear-resistant castables, the main raw materials are: (1) alumina aggregate, which plays a role in fire resistance; (2) corundum powder, which plays a role in wear resistance.

Second, the light thermal insulation castables, composed of floating beads and alumina aggregates, play a role in refractory insulation.

Third, aluminum silicate fiberboard, the same as the cyclone separator return leg
