Alumina refractory castables are indefinite refractory materials processed by mixing bauxite clinker and refractory fine powder with refractory binding agent in a certain proportion. Xintai Group summarizes: seven important operations of bauxite clinker during the construction of refractory castables are correct, for reference only!

Xintai Group said that the seven important operations of alumina clinker in the construction of refractory castables process are as follows:

1. Anchor nail welding anchor nail materials, specifications, models are selected according to the design standards. Anchor distribution and welding quality are done according to the design standard.

2. Mold frame size is accurate and meets the design requirements. The support points are firm, lap tightly and do not leak. For strongly corrosive or bonded castables, an isolation layer should be set in the mould. The wooden strips of the reserved expansion joints should be fixed firmly to prevent movement when vibrating.

3. The admixture of casting material in the construction of casting material project should be limited to be used up within 30 minutes. The template should be coated with mold release agent before pouring material. The pouring should be completed continuously. The next layer of castables should be completed before the first set of the previous layer of castables. If the work period exceeds its initial setting time, the pouring shall be completed continuously. Before the first set of the previous layer of castings, the next layer of castings should be completed.

4. When using the insertion type vibrator, the thickness of the pouring layer shall not exceed 1.25 times of the length of the vibrating part, and when using the flat column type vibrator, its thickness shall not exceed 200mm.

5. The maintenance of castable silicate refractory castable is suitable for water maintenance, especially the flat column vibrator, and its thickness should not exceed 200mm, especially the high alumina cement castable.

6. Water glass castables should be placed in a dry and manic environment for natural maintenance, no water should be added. Do not use water or steam to cure the mold, but natural curing in a dry and mild environment. If the ambient temperature is low, it should be dried at low temperature.

7. Removal of non-load-bearing molds should be done when the strength of the casting material can ensure that its surface and angles will not be damaged by demolding. Load-bearing moulds can only be demoulded when the strength of the castables reaches 70% or more.

Xintai Group understands that the characteristics of refractory castables are low bulk density, high strength, good air tightness, small line change after firing, low thermal conductivity and high use temperature. Good field performance, especially suitable for wall lining with complex shape. After being built, the furnace wall has strong integrity. Widely used as heat insulation layer of industrial furnace wall lining or high temperature industrial furnace lining. In the process of choosing raw materials for refractory castables bauxite, AL2O3 and refractoriness are two indicators, so be sure to choose the right bauxite products to use.
