Description
Technical Field
The invention relates to the technical field of metal heat treatment processes, in particular to a vertical quenching device for a metal plate blank.
Background
Before the nuclear-grade zirconium alloy plate blank is hot-rolled, the plate blank which is forged and then sawed in sections needs to be quenched so as to achieve certain special performance. At present, the zirconium alloy plate blank quenching in China mostly adopts a box furnace for heating, and the plate blank quenching process is finished by manually finishing the discharging, transferring, horizontally entering water, manually shaking and the like of the blank by using a discharging machine or a crane hanging fork device after heat preservation. This quenching process suffers from the following disadvantages:
1. because the discharging machine or the traveling crane hanging and inserting device is adopted to manually finish discharging and transferring the blank, a great deal of time is consumed in the links of taking the discharging machine in place or taking the traveling crane in place, starting, inserting, transferring and the like, and the time for transferring the blank into water is about 1 minute generally; in the discharging process, the phenomenon that the material transfer is suspended or the quenching is forced to be stopped due to overlong residence time is often caused by the problems of mechanical failure, personnel cooperation, material inserting tools and the like; aiming at the quenching process of the zirconium alloy plate blank with special application, the transfer and water quenching are often required to be completed within ten seconds, and the requirement is greatly different from the actual operation in time.
2. During the horizontal immersion quenching process of the heating plate blank, a large amount of water-vapor diaphragms are often generated on the surface of the plate blank, so that the rapid conduction and diffusion of the internal temperature of the plate blank become slow; and the lower distributed surface of the diaphragm is obviously denser than the upper surface, and the upper surface and the lower surface have heat conduction difference, so that the quenching uniformity of the plate blank is not facilitated, and the performance of the product is reduced.
3. At the moment when the heating plate blank enters water horizontally, large waves are often lifted on the surface of the quenching water tank, and a large amount of quenching liquid and water vapor are generated, so that personnel are easily scalded.
4. The weight of a quenching plate blank is about hundreds of kilograms to 1 ton, and the transfer tool is too conservative in design of a part contacting with a material due to consideration of mechanical strength, so that the contact area of a material fork and the material is large, and the temperature of the contact part is obviously reduced easily by a cold material fork, so that the quenching uniformity is poor.
5. After the plate blank enters water, in order to reduce the influence of an air film on the quenching quality, the film is broken in a mode of manually shaking the material fork, and the actual effect is not ideal;
6. the whole quenching process can be smoothly finished only by 3 persons in tacit cooperation, and the work yield and the personnel use efficiency are not high.
Therefore, how to realize the quick vertical quenching of metal plate blank, effectively avoid the long material transfer time among the quenching process of slab plane, quench inhomogeneous scheduling problem, and can be fine avoid the potential safety hazard that splashes of water and arouse in the quenching process, improve personnel's utilization ratio, improve quenching efficiency is the technical problem that awaits the solution at present.
