Roller bar furnace for aluminum alloy plate

Abstract

The invention belongs to the technical field of aluminum alloy plate heating equipment, and discloses a roller bar furnace for an aluminum alloy plate. The roller bar furnace comprises a furnace body,a liftable multi-layer material storage table and a feeding and discharging roller bar system, wherein the furnace body is used for heating and insulating the aluminum alloy plate, the liftable multi-layer material storage table is positioned in the furnace body and is used for containing the aluminum alloy plate, and the feeding and discharging roller bar system is used for conveying the aluminum alloy plate; the feeding and discharging roller bar system comprises a plurality of bars which are horizontally laid and are in chain transmission, and the bars transversely penetrate through the furnace body; the liftable multi-layer material storage table comprises a material storage frame and a lifting rod; and the material storage frame comprises a plurality of material storage layers for bearing aluminum alloy plates, two cross beams and a plurality of vertical beams, wherein the vertical beams are connected between the two cross beams so as to erect the material storage layer, and thecross beams are connected to the lifting rod so as to realize the lifting motion of the material storage frame. According to the roller bar furnace, automatic control can be realized, the quality of the plate surface is high, and the problems of scratch, deformation and the like of the conventional plate surface are solved.

Description

technical field [0001] The invention belongs to the technical field of heating equipment for aluminum alloy plates, and relates to a roller furnace for aluminum alloy plates. Background technique [0002] Aluminum alloy sheet is widely used in various industries because of its light weight, high strength, corrosion resistance, easy processing and regeneration, etc. Social requirements are increasing, and in order to meet the current needs, aluminum alloy plates have become the best choice for replacing steel materials such as steel plates as materials such as large body panel structures (outer panels, inner panels) and reinforcement materials for automobiles. According to relevant data, the weight reduction and emission effect of aluminum is 1:2.5:20, that is, every 1Kg of aluminum used in a car can reduce its own weight by 2.25Kg, and at the same time, it can also reduce waste emissions by 20Kg during the entire service life of the car. Manufacturing automobiles instead of...

Problems solved by technology

However, almost all enterprises currently adopt the method of vertical quenching and horizontal spray quenching of single-layer roller rods. This kind of equipment has relative limitations.

Vertical quenching has less loading capacity, high energy consumption and large deformation after quenching; single-layer roller rod horizontal spray quenching is mainly aimed at medium and thick plates, the hardenability of thick plates is poor, and the deformation of thin plates is large, and will Scratches on the board surface during the transmission transfer process, which seriously lead to a decline in quality
