Abstract
The invention relates to a heat treatment method-double compression method for a lining plate of a shot blasting room of a high-chromium iron shot blasting machine. The method specifically comprises the steps that the thickness of the lining plate of a shot blasting and a shot blasting chamber is about 8mm, the design of additionally arranging reinforcing ribs is adopted, and then, a clamp is used for clamping the four corners and the middle of the ribs to put the ribs on a quenching hand disc so as to be heated. In the heating process, the small bend in the casing process is straightened, the forced straightening of mechanic parts during quenching is ensured, and the good effect is achieved.
Description
Technical field
The present invention relates to Field of Heat-treatment, specifically, is a kind of heat treating method-double compression of rich chromium cast iron shot-blasting machine shot blast room liner plate.
Background technology
Grow because workpiece is thin, therefore especially very easily deform in thermal treatment in casting, warpage, because rich chromium cast iron fragility is large, can not straightening under normal temperature, can only the nature straightening when high temperature.We adopt lifting heating, and the method for lifting chilling, can solve the problem of distortion preferably, but can not solve the very high problem of hardness, and the problem how solving distortion in oil temperature quenching becomes a great problem.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of heat treating method-double compression of rich chromium cast iron shot-blasting machine shot blast room liner plate is provided.
For achieving the above object, the invention provides following technical scheme:
Ball blast and shot blast room liner plate thickness, at about 8mm, increase reinforcing rib design, are then placed on quenching setting stick with clamp corner and centre and heat.In heat-processed, both aligned little the bending during casting, when ensureing again to quench, skilled worker's part is forced to straighten, and receives very good effect.
Compared with prior art, positively effect of the present invention is:
The problem of distortion can be solved preferably, the problem that hardness is very high and how to solve the problem of distortion in oil temperature quenching.
Accompanying drawing explanation
Fig. 1 is a kind of heat treating method-double compression figure of rich chromium cast iron shot-blasting machine shot blast room liner plate.
Embodiment
The technique means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
Concrete grammar is:
Ball blast and shot blast room liner plate thickness, at about 8mm, increase reinforcing rib design, are then placed on quenching setting stick with clamp corner and centre and heat.In heat-processed, both aligned little the bending during casting, when ensureing again to quench, skilled worker's part is forced to straighten, and receives very good effect.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any Reference numeral in claim should be considered as the claim involved by limiting.
