Description
Technical field:
The utility model relates to a kind of heat treatment special hanger of slag stock pump flow passage part impeller.
Background technology:
Slurry pump impeller is subjected to the powerful impact wear that slag is starched in use, so cast with the rich chromium cast iron material, its Technology for Heating Processing is: 940 ℃ of-1050 ℃ of heating, dry quenching adds medium temperature tempering.Because the shape of impeller is more special, lifting is inconvenient when heat treatment, for making full use of capacity of equipment, all use and hang basket lifting product, product lies in and hangs on the basket, separate with fire brick or special-purpose parting bead between product and the product, lower floor's product can be subjected to the extruding from the upper strata product weight surely, during quenching because the high whole basket back product of coming out of the stove that hangs of temperature disperses cooling difficulty, have to whole hang basket in natural air cooling or with blowing engine facing to blast-cold, product and product, this side of product is seldom even with the there rate of cooling, press together owing to product again, discontinuity, the product of being pressed all may deform and ftracture in the process of heating and cooling.To such an extent as to problems such as the distortion of product, cracking and hardness deficiency are serious.
Summary of the invention:
The purpose of this utility model just provides a kind of heat treatment special hanger of impeller, and it is convenient that this suspender lifts when heat treatment, and cooling evenly makes that workpiece hardness height, hardness after the processing is even, modification is little.
To achieve these goals, the utility model adopts following technical scheme:
Comprise suspension hook, threaded column and suspension ring three parts.The bottom of described suspension hook is hook, and the upper end is a link, and suspension ring are fixed in the threaded column upper end, and the lower end of threaded column is a threaded connection, the pitch of the pitch of the screw thread on this threaded connection and impeller axis hole and measure-alike, and described hook hangs on the suspension ring.
The utlity model has characteristics such as simple in structure, easy to use.
Description of drawings:

5, threaded column 6, threaded connection 7, impeller
The specific embodiment:
Contrast Fig. 1 as can be known, the utility model comprises suspension hook 1, threaded column 5 and suspension ring 4 three parts, the bottom of described suspension hook 1 is hook 2, the upper end is a link 3, suspension ring 4 are fixed in threaded column 5 upper ends, the lower end of threaded column 5 is a threaded connection 6, the pitch of the screw thread on this threaded connection 6 and the pitch of impeller axis hole and measure-alike, and described hook 2 hangs on the suspension ring 4.
In heat treatment process, threaded connection on the threaded column 6 is screwed in the axial thread hole of impeller 7, hang up suspension ring by suspension hook again, suspension hook then hangs in the driving, when air cooling heat treatment, can easily workpiece be hung suitable place like this, make it cooling evenly, reduce and avoid workpiece hardness on the low side, hardness is inhomogeneous, be out of shape bad phenomenon generations such as big.
