Embodiment 1

[0014] The present invention uses waste heat to generate steam bell furnace, such as figure 1 , figure 2 As shown, it includes a hearth 5, a material receiving plate 4, a heating mantle 12 and a cooling mantle 1, and the material receiving plate 4 is located on the upper part of the hearth. The lower part of the furnace platform is provided with a circulation fan device 9, and the heating cover is provided with a heating burner 11, which is connected with gas and air pipelines. The cooling cover 1 is provided with a heating jacket 2, the heating jacket is located around the inner wall and top of the cooling cover 1 cylinder, the heating jacket is provided with a water inlet 8 and a steam outlet 6, the water inlet is located at the lower part of the heating jacket, and the steam outlet is located at the heating Jacket top. The water inlet is connected with the water pipeline, and the steam outlet is connected with the steam pipe network. The outer wall and the top of the co...

Embodiment 2

[0017] Another embodiment of the present invention is as image 3 As shown, the inner wall of the cooling cover 1 is equipped with a steam coil 10 , the lower end of the steam coil is connected to the water inlet 8 , and the upper end of the steam coil is connected to the steam outlet 6 . The water inlet is connected with the water pipeline, and the steam outlet is connected with the steam pipe network. Other structures and operation modes of this embodiment are the same as those of Embodiment 1.

Abstract

The invention relates to a cover-type furnace generating steam by using waste heat. The bell-type furnace generating steam by using waste heat comprises a furnace platform, a stock supporting plate, a heating cover and a cooling cover, wherein the stock supporting plate is located above the furnace platform; a circulating fan device is arranged at the lower part of the furnace platform; the heating cover is provided with a heating nozzle; the heating nozzle is connected with gas and air pipelines; the cooling cover is provided with a steam generator; the steam generator consists of a heating jacket and a steam coil pipe; the steam generator is provided with a water inlet and a steam outlet; the water inlet is located at the lower part of the steam generator; the steam outlet is located at the upper part of the steam generator; the water inlet is connected with a water pipeline; and the steam outlet is connected with a steam pipe net. By additionally mounting the steam generator on the inner wall and the top of the cooling cover, the steam is generated by using the heat radiated in the cooling process after thermally treating steel billets, incorporated into the steam pipe network and used for generating via a generator or other purposes, so that the cover-type furnace generating steam by using waste heat has the advantages of making full use of the waste heat in the thermal treatment on the steels, saving energy, reducing thermal treatment production cost and being good for environment protection.

Description

technical field [0001] The invention belongs to the technical field of metal heat treatment equipment, and relates to a bell furnace, in particular to a bell furnace which utilizes waste heat to generate steam. Background technique [0002] Material annealing mainly has two basic functions, one is to eliminate hardening and residual stress generated during processing, soften the material, improve plasticity, and facilitate further processing. The second is to change the structure of the material to obtain the required grain size and grain orientation. Bell furnace annealing is one of the main technologies for heat treatment of cold-rolled steel. Generally, bell furnace annealing adopts a single stack or multiple stacks. After the steel is stacked, a protective cover is placed on it, and a protective gas is introduced, and then a heating cover is placed on it. Heating between the heating hood and the protective hood, the heat is transferred to the steel through the flow of p...
