Abstract
The invention discloses a method for fusion covering high-strength stainless steel on a surface of a stand column. The method comprises the steps of carrying out fusion covering treatment on the surface of the stand column by adopting a 3Cr13 stainless steel material, and then carrying out turning; carrying out surface quenching on the turned surface; and polishing the quenched surface. The surface hardness of the treated stand column can reach HRC50 or more, and the application requirement can be met.
Description
Technical field
The present invention relates to a kind of coal-mine hydraulic support leg surface recovery technique, particularly relate to the method for a kind of leg surface high-strength stainless steel cladding.
Background technology
In use for some time, surface there will be the defects such as scuffing, wearing and tearing to coal-mine hydraulic support column, needs to repair its surface.
Restorative procedure of the prior art, one is that column surface machines rear plating iron, chromium plating, the outer wall in use easy peeling that this method is repaired; Another kind method carries out cladding rear car by column surfaces such as electric welding, gas welding, laser to process.
In prior art, be all generally, after cladding is carried out on employing 304 stainless material column surface, process, the leg surface that this method is repaired, hardness, at below HRC40, is difficult to meet service requirements.
Summary of the invention
The object of this invention is to provide the method for the high leg surface high-strength stainless steel cladding of a kind of surface hardness.
The object of the invention is to be achieved through the following technical solutions:
The method of leg surface high-strength stainless steel of the present invention cladding, comprises step:
First, after adopting 3Cr13 stainless material column surface to carry out cladding process, machine;
Then, hard surfacing is carried out to the surface after Vehicle Processing;
Afterwards, polished in the surface after quenching.
As seen from the above technical solution provided by the invention, the method of the leg surface high-strength stainless steel cladding that the embodiment of the present invention provides, cladding process is carried out owing to adopting 3Cr13 stainless material column surface, and hard surfacing and polishing are carried out to the surface after Vehicle Processing, hardness can reach more than HRC50, can meet service requirements.
