A round bar integral walking heating furnace

Abstract

The invention provides an integral step-type heating furnace with a round rod, belonging to the technical field of a charging system of a fuel gas step heating furnace. The integral step-type heating furnace with the round rod is used for solving the problem that the furnace temperature fluctuation is great when a gate type feeding device and a discharging device are started. The integral step-type heating furnace with the round rod is characterized in that a smoke discharging system and a feeding cantilever device are arranged at the same side of a heat storage cavity, wherein the middle part of the feeding cantilever device is fixed on the heat storage cavity; the end part of a discharging cantilever device is equipped with a discharging cantilever roller; a feeding device and the feeding cantilever device are vertical to each other on the same plane; a discharging device and the discharging cantilever device are vertical to each other on the same plane; and the differences between the diameters of a feeding hole and a discharging hole and the diameter of the round rod are 6cm-10cm. The integral step-type heating furnace with the round rod disclosed by the invention can be used for enabling the temperature fluctuation difference inside the heat storage cavity to be small, enabling the heating temperature fluctuation of the round rod to be small and enabling the heating to be uniform, so that a temperature fluctuation problem in a gate type step furnace is solved. The integral step-type heating furnace with the round rod is simple in structure and capable of realizing industrial popularization.

Description

technical field [0001] The invention belongs to the technical field of the charging system of a gas-fired walking heating furnace, in particular to a round rod integral walking heating furnace. Background technique [0002] Heating furnace is a necessary equipment for heat treatment, and walking heating furnace is very popular in the heat treatment industry due to its high heat utilization efficiency, greatly increased output, and high production automation level. The existing walking heating furnace is mostly used for steel heat treatment. The existing technology Most of the walking heating furnaces are gate-type feeding and discharging. When feeding, start the inlet gate, and when discharging, start the discharge gate. The temperature difference between the furnace and the outside of the furnace can reach more than 1000°C. At the same time, because the heat transfer will cause the temperature fluctuation in the furnace, affect the heat treatment effect, surface treatment d...
