Description

Technical Field

[0001] The utility model relates to the technical field of alloy cold rolling, and more specifically, to a cold rolling treatment device for iron-based alloy processing. Background Art

[0002] Iron-based alloys are a type of hardfacing material that is widely used, including martensitic alloys. The main hardening element is Cr, and there are also strengthening elements such as Si, Mo, Mn, V, and W. The total amount of alloying elements does not exceed 10%. The coating structure is low-carbon martensite, with good machining performance, excellent impact toughness, and good stress fatigue resistance and hot and cold fatigue resistance. The material is made of metal wire and tubular wire submerged arc surfacing, with good welding performance and not easy to crack. Typical uses are parts that roll or slide without lubrication between metals. Such as hot rolling work rolls, support rolls, continuous casting machine rolls, guide rolls, straightening rolls and excavator rolls.

[0003] The strength and hardness of iron-based alloys can be improved by cold rolling. Most of the existing cold rolling processing devices apply pressure to the iron-based alloy through two sets of cold rolling rollers arranged upper and lower, so that the iron-based alloy passes through the gap between the two sets of cold rolling rollers to complete the cold rolling processing of the iron-based alloy.

[0004] However, during the rotation of the two sets of cold rolling rollers, the iron-based alloy is easily displaced between the two sets of cold rolling rollers. At the same time, most of the existing cold rolling rollers are fixed on the cold rolling processing device, which is inconvenient to replace the cold rolling rollers, thereby adjusting the height between the cold rolling rollers according to different processing conditions. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a cold rolling processing device for iron-based alloy processing, in which two sets of side rollers are symmetrically arranged at the bottom of the main roller shaft to ensure that the iron-based alloy will not be offset during the cold rolling process, and at the same time it is convenient to adjust the height of the main roller shaft, thereby realizing the height between the cold rolling rollers according to different processing conditions.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
