Small roller and roller sleeve quenching treatment device and heat treatment method

Abstract

The invention relates to the technical field of machining and manufacturing of small rollers and roller sleeves, and relates to a portable small quenching device used for conducting spray quenching heat treatment outdoors or in a temporary field after the small rollers and the roller sleeves are roughly turned and formed, and a corresponding heat treatment method using the device. The quenching treatment device and the heat treatment method are complete in system, complete in function, convenient and reliable to operate, small in capital investment and quick in effect, and the problems that anexisting plant space is narrow and an existing place is endowed with multiple purposes can be solved; or the heat treatment operation is conducted in the open air and outdoors, under the condition that facilities, such as a quenching device and a quenching pool, are not fixed, all components can be combined on an irregular bottom plate, operation is achieved through a crown block or a crane withthe weight being 5 tons or above, only needed quenching liquid or gas needs to be prepared in advance, and through switching of the quenching device, the small rollers or the roller sleeves are rotated on the quenching device at a constant speed, and therefore any combined quenching mode integrating liquid, wind and air can be met, and the quenching quality of the small rollers or the roller sleeves is ensured.

Description

technical field [0001] The present invention relates to the technical field of processing and manufacturing of small rolls and roll sleeves, and relates to spray quenching heat treatment outdoors or temporary places after small rolls and roll sleeves are roughly formed, the portable small quenching device used, and the corresponding heat treatment using the device method. Background technique [0002] Heat treatment is a key link in the quality assurance of small rolls and roll sleeves. At the beginning of the design of the new plant, a certain area will be reserved for the quenching device, which is specially used for quenching equipment for small roll sleeves, and has a corresponding hydroelectric power energy pipeline network. Support, but for some established workshops, the working space is narrow, there is no dedicated heat treatment area, and the limited space is given multiple purposes, and fixed quenching facilities cannot be set up; or heat treatment operations are ...

[0002] Heat treatment is a key link in the quality assurance of small rolls and roll sleeves. At the beginning of the design of the new plant, a certain area will be reserved for the quenching device, which is specially used for quenching equipment for small roll sleeves, and has a corresponding hydroelectric power energy pipeline network. Support, but for some established workshops, the working space is narrow, there is no dedicated heat treatment area, and the limited space is given multiple purposes, and fixed quenching facilities cannot be set up; or heat treatment operations are carried out outdoors and outdoors. Under the condition of fixed equipment and quenching pool and other facilities, it is necessary to adopt a new heat treatment method to carry out spray quenching heat treatment on small rolls or roll sleeves, and to adapt the existing quenching device to achieve the predetermined heat treatment effect of small rolls and roll sleeves.
