Efficient gas type stepping furnace

Abstract

The invention relates to an efficient gas type stepping furnace. The efficient gas type stepping furnace comprises a furnace shell and a hearth. The furnace shell is a rectangular box type body. A material inlet and a material outlet are formed in the furnace shell. A material storage frame used for containing workpieces is arranged in the hearth. The left side and the right side of the furnace shell are each provided with a high-temperature smoke inlet communicated with the hearth. A diversion plate dividing the hearth into a left side area and a right side area is vertically arranged in the hearth. The shape of the diversion plate is matched with the shape of the inner portion of the furnace shell. The top end of the diversion plate is connected with the top of the furnace shell in a sealed manner. The bottom end of the diversion plate is located on the material storage frame. By forming the two high-temperature smoke inlets in the left side and the right side of the furnace shell and through the combination with the diversion plate dividing the hearth into the left area and the right area which are symmetrical, it is ensured that smoke flowing in the hearth is uniform and temperatures of all positions in the hearth are consistent while the heating efficiency is improved, and the temperature field stability is improved.

Description

Technical field: [0001] The invention relates to the technical field of furnaces for heat treatment, in particular to a high-efficiency gas-fired walking furnace. Background technique: [0002] Recently, the heat treatment of workpieces is generally heated by resistance furnaces. However, due to the long heating time and high energy consumption, especially for high-temperature heat treatment of large workpieces and special materials, the thermal efficiency and high-temperature stability of resistance furnaces cannot meet the needs of actual production. . The gas heat treatment furnace mainly uses the high-temperature flue gas produced by the combustion of combustible gases such as natural gas and methane as the heat source. Since combustible gases such as natural gas and methane are clean energy, they have large storage capacity, energy saving, environmental protection, and fast heating speed. In recent years, they have become popular in the industry has been widely used. ...

Problems solved by technology

[0003] The existing gas-fired heat treatment furnace provides a heat source for heat treatment by providing a high-temperature flue gas inlet 2' connected to the burner on the furnace body 1'. As we all know, due to the fast heating speed of the gas, the temperature difference inside the furnace body is large, especially For large-sized trolley furnaces or ordinary box-type furnaces, only one heat source is used, and its heating efficiency is slow, which brings great problems to the temperature uniformity inside the furnace body, and the heating time is long, which affects the heat treatment effect
