Embodiment Construction

[0039] In the present invention, take the end where the furnace door 2 is located as the front end of the annealing furnace.

[0040] like Figure 1 to Figure 7 As shown, the aluminum coil annealing furnace with uniform temperature control of the present invention includes a furnace body 1 and an electric control device 21. A furnace is provided in the furnace body 1, and a door opening for aluminum coils to enter and exit is provided on the front wall 11 of the furnace body 1. There is a furnace door 2 for closing the door opening from front to back; the door opening is figure 1 The center is blocked by the furnace door 2, and the hearth is a conventional structure, which is also blocked by the furnace door 2 and the furnace body 1, so the figure is not shown. The electric control device 21 preferably adopts PLC, and certainly also can adopt single-chip microcomputer or integrated circuit. The electric control device 21 can be installed on the furnace body 1 , or can be ins...

Abstract

The invention discloses a uniform temperature control type aluminum roll annealing furnace. The aluminum roll annealing furnace comprises a furnace body, an electric control device and a furnace door, wherein electric heating devices are arranged in a hearth; the electric control device is connected with a memory which stores a preset working temperature; a positive and negative rotation speed reducing motor is arranged on the top wall of a furnace body and is connected with a transmission shaft, the left and right ends of the transmission shaft are connected with the furnace door through a chain lifting mechanism; multiple groups of electric heating devices are symmetrically arranged at left and right sides in the hearth; a plurality of temperature sensors are uniformly arranged on the front-back direction in the hearth, and the temperature sensors, the electric heating devices and circulating fans are connected with the electric control device; and the temperature sensors, the electric heating devices and the circulating fans are arranged in a one-to-one corresponding manner. According to the uniform temperature control type aluminum roll annealing furnace, the furnace door tightly presses a furnace body front wall from front to back by virtue of dead weight of the furnace door, and the temperature at each part in the hearth during working is more uniform, so that the thermal treatment quality is more uniform and stable.

Description

technical field [0001] The invention relates to the technical field of aluminum processing, in particular to an annealing furnace for aluminum coils with uniform temperature control. Background technique [0002] The annealing furnace is a heat treatment process equipment commonly used in the metallurgical and mechanical industries. Generally speaking, the annealing treatment process is the final treatment process of metallurgical and mechanical products, and its treatment effect will directly affect the quality of the product. [0003] There are many types of annealing furnaces, such as oil furnaces, gas furnaces, electric furnaces, etc. according to fuel. [0004] 1. Oil-fired furnace: Due to the high requirements for the surface quality of the product after heat treatment and the strict requirements for heating accuracy, light diesel oil is generally used for the annealing furnace of fuel oil. This also brings some problems, such as: the price of light diesel oil is rel...
