Description
Technical field
The utility model relates to a kind of annealing devices more particularly to a kind of for plate and the annealing device of bar.
Background technique
In Field of Heat-treatment, when workpiece heats in heating zone, plate or linear workpiece are usually used in heating zone
Roller bottom furnace or air cushion furnace are heated.After temperature is increased to certain value, the intensity of workpiece material declines rapidly, there is two at this time
Kind influences so that thermal deformation occurs in the workpiece after heating.
As shown in Fig. 1, since the roller in the furnace of roller bottom is intermittent arrangement, workpiece has one between the supporting point in heating zone
In fixed distance, such as the section A, workpiece will be because generating bending between two rollers under self gravitation effect, this deformation is being dropped
It will be irrecoverable after temperature.As shown in Fig. 1, when workpiece heats in heating zone, the Workpiece length between each supporting point will be dynamic
It is extended during heating, (by taking aluminum alloy plate materials are in the roller bottom stove heating of 500mm roll spacing as an example, temperature increases 500 degree, heat
The coefficient of expansion be 25 × 10^-6 in the case where, then the elongation between a roll spacing is up to 6.25mm), also, workpiece will with it is each
Friction is generated between supporting point, since hot lower usual frictional force is all larger, the thermal stretching at both ends carrys out self-supporting due to being not affected by
The frictional force inhibition of point can normally extend, and the workpiece in such as B area of middle section, and both ends are supported rubbing a little simultaneously
It wipes power inhibition and the workpiece portion from adjacent area squeezes, the elongation of thermal stretching cannot effectively be discharged, then easily be led
Workpiece is caused to generate in the deformation in this region, especially when work plate is relatively thin, this phenomenon easily occurs.In addition, for line or
Strip-shaped work is also such.So that the product produced has ripple glaze or curved quality problems.And the basis deformed herein
On, the workpiece after correction can have internal stress certainly, influence the quality of product.
For quenching, heating is completed to immediately enter quenching area, this process is in traditional handicraft and free, because
This easily generates quenching distortion under conditions of inhomogeneous cooling weighs, and usually template can be generated in portraitlandscape after thin plate quenching
Very big wave, thus the serious quality for influencing plate.It quenches online although also having in type extrusion process and draw to type
The way of fire, as application No. is a kind of Quenching Sheet board-shape control method and device, one ends shown in CN201410489786.8
Squeeze out profile one end using traction, but its traction purpose be mainly control squeeze out workpiece straightness, the temperature of workpiece not by
Control, the temperature difference range is larger, and the temperature of workpiece is not easy to control, and workpiece is without insulating process, thus solid solubility not can control, and more attach most importance to
What is wanted is that it only applies tension to quenching process, without applying this process of tension during heating, thus is still existed interior
Stress fundamentally can not provide internal stress small and straight workpiece for subsequent handling.
