Heat treatment furnace with movable furnace cover

Abstract

The invention relates to a heat treatment furnace with a movable furnace cover and belongs to the technical field of heat treatment. The heat treatment furnace with a movable furnace cover is connected with a combustion system, a measurement and control system and a smoke evacuation system, and comprises a furnace stage, inside which two combustion chambers and a flue are vertically arranged, wherein the flue is positioned between the two combustion chambers and two ends of the combustions are equipped with burners. The upper surface of the furnace stage is provided with a movable furnace cover, two ends of which are equipped with fire doors. A heating chamber is disposed in the inner space of the furnace cover. And the heating chamber respectively communicates with the combustion chambers and the flue through open pores on the furnace stage. In comparison with car-type furnaces, the heat treatment furnace provided by the invention has advantages of light furnace cover, low mobile power of the furnace cover, good furnace seal performance, uniform furnace temperature, few burners, full combustion and the like. The thermal efficiency of the furnace reaches up to more than 36% through measuring and calculating.

Description

technical field [0001] The invention relates to a heat treatment furnace, which belongs to the technical field of heat treatment. Background technique [0002] Annealing of modified materials is one of the important processes in the manufacture of standard parts. Due to the large batch size, it is of great significance to reduce the unit energy consumption; the uniformity of the furnace temperature and the uniform structure of the annealed material play a key role in improving the productivity. [0003] The pipes and flues of the existing traditional fuel trolley heating furnace are located on both sides and above the furnace body, which directly affects the sanitation and indoor temperature conditions of the workshop, and hinders the operation of the bridge crane in the workshop. There are rigid burner air distribution pipelines, flue pipes and heat exchangers on both sides and top of the traditional structure furnace body, which are fixed and cannot be moved. High failur...
