Abstract
The invention discloses a kind of heat resistant and wear resistant type hearth roll, including roller, the roll shaft for being connected to roller both ends；Roll shaft end is provided with external screw thread, and roller both ends are provided with internal thread hole, and roll shaft end external screw thread is threadedly coupled with roller end internal thread hole；Further improvement is that：Roller end internal thread hole is provided with the alignment pin for extending radially through roller end internal thread hole hole wall insertion roll shaft end with roll shaft end male threaded joint position；Roller surface is provided with resistance to high temperature oxidation wear-resistant coating.Convenient and swift, high temperature resistant is taken in roller of the present invention, roll shaft assembling apart, anti-oxidant, wear-resisting.
Description
Technical field
The present invention relates to a kind of hearth roll of normalizing furnace in Rolling production.
Background technology
The hearth roll of normalizing furnace is typically made up of heat-resisting alloy steel, generally comprises roller, is connected to the roll shaft at roller both ends,
Roll shaft insertion roller end, is fixedly connected, the major defect of this structure is by interference fit：Roller, roll shaft assembling or
Take apart time-consuming bothersome.
The content of the invention
It can significantly improve roller, roll shaft assembling in view of the deficiencies of the prior art, the present invention provides a kind of or take efficiency apart
Heat resistant and wear resistant type hearth roll.
The present invention is achieved through the following technical solutions technical goal.
Heat resistant and wear resistant type hearth roll, including roller, the roll shaft for being connected to roller both ends；It is theed improvement is that：It is described
Roll shaft end is provided with external screw thread, and the roller both ends are provided with internal thread hole, roll shaft end external screw thread and spiral shell in roller end
Pit is threadedly coupled.
In said structure, roller end internal thread hole is provided with roll shaft end male threaded joint position and extends radially through roller
The alignment pin of cylinder end internal thread hole hole wall insertion roll shaft end.
In said structure, the roller surface is provided with resistance to high temperature oxidation wear-resistant coating.
In said structure, the resistance to high temperature oxidation wear-resistant coating is MCrAlY coatings.
The present invention compared with prior art, has the positive effect that：
1st, roller, roll shaft are connected through a screw thread, roller, roll shaft assembling or take apart it is convenient and swift, significantly improve roller, roll shaft assembling
Or take efficiency apart.
2nd, roller end internal thread hole and roll shaft end male threaded joint position, which are provided with, extends radially through roller end internal thread
The alignment pin of hole hole wall insertion roll shaft end, on the one hand prevents roller, roll shaft from circumferentially rotating and make it that threaded connection loosens, separately
On the one hand roller, the structural strength of roll shaft connection are also significantly improved.
3rd, roller surface is provided with resistance to high temperature oxidation wear-resistant coating, is remarkably improved the resistance to high temperature oxidation, wear-resistant of the present invention
Performance.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is I part close-up schematic view in Fig. 1.
Embodiment
The invention will be further described below according to accompanying drawing and in conjunction with the embodiments.
Heat resistant and wear resistant type hearth roll shown in the drawings, including roller 1, two roll shaft 2, alignment pin 3；The end of roll shaft 2
Provided with external screw thread, the both ends of roller 1 are provided with internal thread hole, and the end external screw thread of roll shaft 2 is threadedly coupled with the end internal thread hole of roller 1.
Alignment pin 3 extends radially through end internal thread hole hole wall insertion roll shaft 2 end of roller 1.
The surface of roller 1 is provided with resistance to high temperature oxidation wear-resistant coating 1.1, and in the present embodiment, resistance to high temperature oxidation wear-resistant coating 1.1 is
MCrAlY coatings.
