Steel plate heat treatment equipment and technology

Abstract

The invention provides a steel plate heat treatment equipment, comprising a heating furnace, a quenching device, a tempering furnace and a conveying device for transferring the steel plate from the heating furnace to the quenching device and then to the tempering furnace. When the above-mentioned steel plate heat treatment equipment is used for the heat treatment process, it is only necessary to manually place the steel plate in the heating furnace. After the heating furnace is heated and kept warm, the steel plate is transferred to the quenching device by the conveying device for quenching, and then the conveying device is used. Tempering is carried out in the furnace, and then the steel plate can be taken out from the tempering furnace; therefore, in the process of heat treatment by the above-mentioned steel plate heat treatment equipment, the manual handling process is omitted, and the transmission time of the steel plate from the heating furnace to the quenching device is shortened, thereby reducing the time. The heat loss of the steel plate during transportation reduces the influence of heat loss on the quenching hardness of the steel plate, and reduces the labor of workers. The invention also provides a steel plate heat treatment process, which is performed by using the steel plate heat treatment equipment provided by the invention.

Description

technical field [0001] The invention relates to the technical field of heat treatment, more specifically, to a steel plate heat treatment equipment, and the invention also relates to a steel plate heat treatment process. Background technique [0002] Heat treatment is a metal thermal processing process in which metal materials are heated, kept warm, and cooled in a certain medium, and their properties are controlled by changing the metallographic structure on the surface or inside of the material. [0003] The steel plate heat treatment equipment in the prior art includes a box furnace, a quenching device and a tempering furnace. The process steps of using the above heat treatment equipment are: first put the steel plate into the box furnace for heating and heat preservation, and then manually take out the steel plate and place it Clamp it into the quenching device (water tank or oil tank) for quenching. After quenching, clamp the steel plate into the tempering furnace. Afte...

Problems solved by technology

[0004] Since there is no connection between the box furnace and the quenching device, the quenching device and the tempering furnace, in the above process steps, the steel plate is manually transported from the box furnace to the quenching device, and then the steel plate is transported from the quenching device to the tempering furnace. If the time is long, it is easy to cause heat loss of the steel plate, which affects the quenching hardness of the steel plate and increases the labor load of the workers.

[0005] In addition, when the above-mentioned quenching device is used for quenching, the steel plate is in a free state, and the amount of deformation after quenching is large, which is prone to crack defects, especially some narrower, longer and thinner steel plates are provided with tenon grooves after heat treatment. The parts are prone to stress concentration, which leads to quenching crack defects, and the amount of quenching deformation is large, which increases the labor load of workers in the process of correcting flatness
