Thermal insulation construction and method used for steel slag thermal smouldering device

Abstract

The invention provides a thermal insulation construction and method used for a steel slag thermal smouldering device. The thermal insulation construction provided by the invention is characterized in that a thermal insulation layer of a thermal insulation device is internally provided with a constructional reinforcement and is filled with thermal insulation castable, so as to reduce the temperature of a concrete construction and protect the concrete construction. Compared with the prior art, the thermal insulation construction disclosed by the invention can be used for effectively and greatlyreducing the working temperature of the concrete construction, improving the durability of concrete, enabling the thermal insulation castable to achieve better integrity, reducing the maintenance frequency and improving the use security.

Description

technical field [0001] The invention relates to the field of heat insulation structure of a hot stuffy device in a steel slag treatment hot stuffy process in the metallurgical industry. Background technique [0002] The hot stuffy device is the equipment used in the steel slag treatment hot stuffy process. Usually, the side structure of the hot stuffy device is steel slag, steel billet, heat insulation layer, concrete side wall, and soil from the inside to the outside. Since the hot stuffing process uses molten steel slag (with a temperature above 1400 degrees Celsius) directly into the hot stuffing device, and the billet directly contacts the molten steel slag, the thickness of the heat insulation layer between the billet and the concrete is relatively thin, so the concrete side wall and The temperature of the bottom plate will be relatively high. [0003] The heat insulation methods currently used mainly include air heat insulation and slag heat insulation. The advantage ...

Problems solved by technology

[0003] The heat insulation methods currently used mainly include air heat insulation and slag heat insulation. The advantage of these two methods is that the cost is low, but the disadvantage is that the heat insulation effect is not ideal. According to on-site monitoring, these two methods may lead to the highest temperature of the inner wall of the concrete Reaching around 200 degrees Celsius and 150 degrees Celsius, such a temperature state will have a negative impact on the durability of the concrete main structure, resulting in unsafe factors during normal production
