Problems solved by technology

[0002] Now the use of industrial furnaces is more common, but there are still some inconveniences in the daily use of industrial furnaces. For example, the general cooling air inlets of industrial furnaces are all at the bottom of the furnace body, so that the air flow in the furnace body will produce a fluid dead zone. In such a continuous cooling process, the cold air generally rises directly near the air outlet, which makes it easier for the furnace body to cool down near the air outlet and on the side vertically upward along the air outlet. The cooling of other parts is slower and more difficult. These factors lead to different temperatures in different areas of the furnace body, which will seriously affect the cooling effect of the workpiece to be cooled in the furnace body, and affect the quality and efficiency of the industrial furnace.
[0003] At the same time, when the workpiece is heated in the existing furnace body, once the heating time is long, the iron workpiece is easily oxidized and black spots appear. If the workpiece is polished later, the processing difficulty and work of the workpiece will be increased. amount, which is not conducive to the efficient use of industrial furnaces

Abstract

The invention discloses an industrial furnace capable of uniformly lowering the temperature and achieving an atmosphere in the furnace. According to the main points of the technical solution, the industrial furnace comprises an outer furnace body, wherein a temperature-lowering and air-induced device is arranged between an inner tank body and the outer furnace body; the bottom of the outer furnacebody is provided with an air blowing opening and an air blowing machine cooperating with the air blowing opening; an annular air outlet device is arranged inside the inner tank body; the annular airoutlet device communicates with a pipeline; and an air inlet is formed in the outer end part of the pipeline. The industrial furnace capable of uniformly lowering the temperature and achieving the atmosphere in the furnace is reasonable in structure and quite good in using effect, and can effectively solve the requirement of quick and uniform temperature lowering of the furnace body. In addition,the industrial furnace can well control the atmosphere in the furnace, thereby ensuring that workpieces are not prone to be oxidized, and greatly improving the using efficiency of furnace body equipment and the quality of the workpieces.

Description

technical field [0001] The invention relates to an industrial furnace, in particular to an industrial furnace applicable to the industrial furnace which can uniformly lower the temperature and realize the atmosphere in the furnace. Background technique [0002] Now the use of industrial furnaces is more common, but there are still some inconveniences in the daily use of industrial furnaces. For example, the general cooling air inlets of industrial furnaces are all at the bottom of the furnace body, so that the air flow in the furnace body will produce a fluid dead zone. In such a continuous cooling process, the cold air generally rises directly near the air outlet, which makes it easier for the furnace body to cool down near the air outlet and on the side vertically upward along the air outlet. The cooling of other parts is slower and more difficult. These factors cause the temperature of each area in the furnace body to be different, which will seriously affect the cooling ...
