Abstract

The invention discloses an arch load-bearing platform of a fluidized roasting furnace and a pouring method thereof, comprising a main body of the load-bearing platform and a support platform, the main body of the load-bearing platform and the support platform are fastened together through an L-shaped fastening surface, and the main body of the load-bearing platform is composed of multiple layers. Different castable materials are poured in layers, and the layers are separated by hydrophobic fiberboards. The vent holes on the main body of the load-bearing platform are connected by wear-resistant and high-temperature resistant high-alumina ceramic tubes at the junction of different material layers; The water fiber board, the improvement of the matching structure between the main body of the load-bearing platform and the support platform, and the addition of different contents of steel fibers to the castables enable the arched load-bearing platform to reliably withstand the weight of the material itself in the roasting chamber and the high-frequency vibration load during fluidized roasting. It can also effectively prevent materials from falling into the lower combustion chamber from the roasting chamber.

Description

technical field [0001] The invention belongs to the field of fluidized roasting furnaces, and in particular relates to an arched load-bearing platform of a fluidized roasting furnace and a pouring method thereof. Background technique [0002] At present, most of the fluidized roasting furnaces used in my country use high-pressure air to fluidize the materials at the bottom of the furnace, and then directly heat the materials by burning natural gas and diesel in the furnace. But for some materials (such as foundry old sand), when the flame is in direct contact with the material, a small amount of the material will reduce the quality of the roasted material due to excessive local temperature. [0003] In the prior art, some roasters have begun to adopt the method of setting the combustion chamber separately from the roasting chamber, that is, the combustion chamber is directly arranged at the lower part of the roasting chamber. In this way, high-pressure air, natural gas or d...
