Embodiment Construction
[0023] In the following, the specific embodiments of the present invention will be described in further detail in conjunction with the accompanying drawings, so as to make the technical solution of the present invention easier to understand and grasp.
[0024] The energy-saving and clean water-cooled sliding rail heating furnace is an advanced furnace equipment used in the steel rolling industry. The sliding rail is made of corundum sliding rail bricks made of special materials. In order to improve the heat energy utilization efficiency of the heating furnace, the heating furnace designed by the present invention is built with multiple 180°×928mm arched holes (the height can be adjusted according to needs) at the base wall of the high temperature section to match the burners on both sides. The arched hole enables the flame in the combustion chamber of the furnace to be fully burned in all directions. Considering the emission reduction requirements of the heating furnace at the...

Abstract
The invention discloses a clean energy-saving anhydrous cold sliding rail heating furnace and an application method thereof. The heating furnace comprises a smoke generation device, a heating hearth, an air preheater, a cooler, an immersion-type deduster and a steam bleeding pipe along the smoke generation flow direction, wherein the smoke generation device generates smoke in the practical operation process, the smoke is sent into the heating hearth for heating steel billets or steel ingots; the smoke successively flows through a high-temperature zone, a medium-temperature zone and a low-temperature zone and is discharged into the air preheater from a smoke furnace for gas cooling; after normal-temperature air is preheated, secondary air is formed to be sent into the heating hearth for supporting combustion; the gas-cooling smoke is processed by the cooler and the immersion-type deduster; and heat in the smoke and solid particles are respectively utilized to generate steam, raw materials for making bricks and the like to recycle. According to the clean energy-saving anhydrous cold sliding rail heating furnace and the application method thereof which are disclosed by the invention, the heat efficiency of the heating furnace for steel rolling is improved, fuel can be fully utilized within the high limit; and meanwhile, the purpose of a metallurgical system on energy conservation and emission reduction is feasibly realized.
Description
technical field [0001] The invention relates to a steel rolling production line adopting waterless cooling and heating furnace technology, a flue gas treatment system and a working realization method thereof, belonging to the field of energy saving and consumption reduction in the metallurgical industry. Background technique [0002] In today's environment of energy conservation and emission reduction, it is imperative for the metallurgical industry to save energy, reduce consumption and reduce emissions. The heat taken away by the cooling water (vaporization cooling) of the traditional water-cooled furnace bottom tube steel rolling heating furnace accounts for ≥ 15% of the total heat of the furnace body. The heat loss will be as high as 25% to 30%. In this regard, as an enterprise engaged in the research and development of metallurgical industrial furnaces, in order to reduce the heat energy consumption of industrial furnaces, reducing energy loss is the responsibility.
