A high-efficiency gas-fired walking furnace

Abstract

The invention relates to a high-efficiency gas-fired walking furnace, which includes a furnace shell and a furnace. The furnace shell is a rectangular box-shaped body. The furnace shell is provided with a material inlet and a material outlet, and the furnace is provided with a storage rack for placing workpieces. , the left and right sides of the furnace shell are respectively provided with high-temperature flue gas inlets communicating with the furnace; the furnace is vertically provided with a deflector that divides it into a left area and a right area. The inner shape of the furnace shell is suitable, the top end is airtightly connected with the top of the furnace shell, and the bottom end is located above the storage rack. In the present invention, two high-temperature flue gas inlets are arranged on the left and right sides of the furnace shell, combined with a deflector that divides the furnace into two symmetrical areas on the left and right, so as to improve the heating efficiency and ensure that the flue gas in the furnace flows evenly. The temperature is consistent everywhere, improving the stability of the temperature field.

Description

[0001] Technical field: [0002] The invention relates to the technical field of furnaces for heat treatment, in particular to a high-efficiency gas-fired walking furnace. [0003] Background technique: [0004] 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...

Problems solved by technology

[0005] 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
