Construction advantages of amorphous refractories
2023-07-07
The construction of amorphous refractories refers to the refractory materials that are formed by casting, self-flow, pumping and spray molding. In short, self-flow pouring materials are suitable for parts that are not easy to vibrate and shape; pumping materials are suitable for long-distance, high-difference, large-quantity and fast construction; jet materials are suitable for parts that are inconvenient for die support. In developed, self-flow. Pumping and jet-forming refractories have been widely promoted. These new amorphous refractories will have more room for development. For the construction of prefabricated components of large-scale homogeneous furnaces in plastic refractories, the pump injection method of castables can be said to be a representative new construction method. The prefabricated member method of plastic refractories can obtain a well-managed quality structure by further shortening the construction time. This method divides large furnaces such as homogeneous furnaces into several pieces for construction and assembles them after construction. The advantage of this method is that the inhomogeneity of filling density is eliminated by the punch-in method and the overall structure is obtained in a short time. Table 1 shows the comparison method of this method with the refractory brick masonry construction method, which can basically complete the construction in 1/2 time. In addition, the pump injection method in the castable nearly expands the construction scope to produce the necessity of uniform pouring. The pump injection method actually adopts a feasible construction method. The characteristic of this method is that after mixing, it is accurately delivered by the pump to the determined position. Due to the pouring construction, it has the following advantages: 1. The pouring quality does not decrease, and the raw moisture is the same; 2. The construction speed is increased by 2 to 20 times; 3. The construction cost is reduced by 10% to 20%, and the construction personnel are significantly reduced. (4) High-altitude construction also has the advantages of fast operation.
