Uniform-temperature heating furnace

Abstract

The invention discloses a uniform-temperature heating furnace. The uniform-temperature heating furnace comprises a furnace body. A flue is formed on the top of the furnace body, and a temperature detector and a burner device are installed on the top of the furnace body. A combustion chamber is formed in the furnace body, and a feeding inlet and a discharging outlet are formed in the left side andthe right side of the combustion chamber correspondingly. A feeding transmission mechanism is arranged on the feeding inlet side, and a discharging transmission mechanism is arranged on the discharging outlet side. Girders are installed in the combustion chamber and penetrate through the space between the feeding inlet and the discharging outlet. The burner device comprises a burner body, and a fuel gas inlet and air inlets are formed in the burner body. The head ends of the girders are installed on a fixing shaft in a sleeved mode, and a hydraulic cylinder is installed at the tail ends of thegirders. A flame guide pipe is installed at the outlet end of the burner body in a sleeving mode, an installation plate is arranged on the outer wall of the burner body, an edge opening is formed ina pipe opening of the flame guide pipe and connected with the installation plate through a transfer plate, and the outlet end of the flame guide pipe is of a hook-shaped structure. The uniform-temperature heating furnace is simple in structure. Due to the fact that the flame guide pipe is installed on the existing burner body, disassembly is convenient, the heating direction of the burner body canbe changed at will, the heating area of the burner is increased, and the uniform-temperature heating furnace has the high application and promotional value.

Description

technical field [0001] The invention relates to the technical field of heat treatment equipment, in particular to a uniform temperature heating furnace. Background technique [0002] In the metallurgical industry, a heating furnace is a device that heats materials or workpieces to the temperature of rolling to forging. Heating furnaces are used in petroleum, chemical, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, pharmaceuticals and many other industries. [0003] At present, the burner devices commonly used in heating furnaces are divided into two types: top spray and side spray. steel is heated. When the steel in the heating furnace is heated by means of installation on the furnace roof or side wall, there are problems such as single heating direction and small heating area. At the same time, since the heating furnace is a customized equipment, it is necessary to make different desi...

AI Technical Summary

Problems solved by technology

When the steel in the heating furnace is heated by the installation method on the furnace roof or side wall, there are problems such as single heating direction and small heating area.

At the same time, since the heating furnace is a customized equipment, it is necessary to make different design changes to the appearance and size of the heating furnace according to the customer's requirements during design. In some cases, the heating furnace designed and manufactured for the customer cannot When the burner is installed on the side wall and the burner is installed on the top (usually installed in the middle of the furnace top), and the furnace top has too many pipes, the installation position is not enough, and the temperature uniformity of the combustion inside the furnace body cannot be guaranteed.
