Wholesale Magnesium Bricks-What are the advantages of lightweight castable construction?

In industrial production, we will use a lot of refractory materials in the wholesale of magnesia bricks. Generally speaking, according to the types of materials, refractory materials are mainly divided into three types, namely: heavy refractory materials and medium refractory materials. And light refractory materials. Common refractory materials are mainly heavy refractory materials, especially during boiler construction. Today we will focus on introducing another refractory material, light refractory material as castable. the benefits of.

In the preparation of lightweight castables, refractory materials with larger particles and larger densities are selected as the aggregates required for the material.When the lightweight castables are prepared, the aggregates used are large and fine particles. The strength of large particles is 5-20mm, and the fine particles are 0-5mm. The aggregates selected for the preparation of lightweight castables are generally ceramics, porous clinkers, bleaching beads, expanded perlite, alumina hollow balls, and vermiculite. Raw materials, lightweight castables have a large volume, but the materials are extremely light, and when looking at lightweight castables, you will find that there are large particles of aggregate in the castable, but this aggregate is often lighter.

When using lightweight castables, the castables selected are generally used in the middle layer of the boiler construction. Lightweight castables are used as a type of thermal insulation, mainly because the lightweight castables have thermal and thermal insulation. Characteristics, but the fire resistance and wear resistance are poor, so in general, the construction of lightweight castables will be directly used in the insulation layer or the furnace roof area of the power plant.
