Description

Technical Field

[0001] The invention relates to the technical field of refractory material construction, and in particular to a pouring and unloading platform with a heating function and a use method thereof, which is mainly used for the masonry construction of furnace lining castables for high-temperature containers such as iron ladles and steel ladles. Background Art

[0002] The pouring construction method of unshaped refractory materials can improve the construction efficiency of refractory materials and the integrity of the furnace lining structure, so it is increasingly widely used. At present, the permanent layer masonry of high-temperature containers such as ladles and steel ladles of steel enterprises mostly adopts the pouring process. During the construction process, the stirred unshaped refractory materials need to be poured into the mold through the feeding platform. The stability and uniformity of the feeding process directly affect the quality of pouring and the service life of the refractory materials.

[0003] The size specifications of the iron ladle and steel ladle in the enterprise are quite different. In addition to the different sizes of the molds, the position and size of the feeding port should also be adjusted frequently. The feeding port of the feeding platform in the existing technology is fixed, and the castable can only be poured into the mold from a few fixed positions, which seriously affects the pouring efficiency and uniformity. At the same time, for pouring targets of different sizes and shapes, it is necessary to match the corresponding size of the feeding platform separately, resulting in the need for the same enterprise to prepare multiple sets of special feeding equipment of different sizes at the same time, causing inconvenience in construction organization and increased equipment costs.

[0004] In addition, the existing material discharging platform usually lacks a dynamic stirring mechanism. In order to ensure the smooth discharging process, it is necessary to add sufficient water to improve the fluidity of the castable. However, adding too much water has an adverse effect on the high-temperature performance of the castable. At the same time, the fluidity of the castable is greatly affected by temperature. The fluidity will decrease under low temperature conditions such as winter. The existing self-flowing pouring scheme often requires the addition of more water.

[0005] In addition, with the increasing demand for insulation of containers such as steel ladles and iron ladles, more and more companies are adopting the process of attaching insulation boards to the inner shell and then pouring the permanent layer. However, due to its own waterproofness and strength, the insulation board cannot withstand the adverse effects of high-intensity erosion of the castable during the pouring process. Summary of the invention

[0006] The technical problem to be solved by the present invention is: in view of the shortcomings of the prior art, a pouring and unloading platform with a heating function and a method of using the same are provided, which can adapt to the pouring working conditions of a variety of molds of different sizes, high-temperature containers of different capacities, and different construction sites, and can greatly improve the efficiency and use effect of on-site construction of the pouring material, and reduce the use and maintenance costs of the equipment.
