Background technology
Roll is important consumption spare part in Rolling production, and a large amount of consumption of roll cause the huge wave of resource and the energy
Take.Particularly in hot rolling production process, roll condition of work is extremely harsh, not only to there is good wearability, also to there is excellent
Resistance to high temperature oxidation and crack propagation of thermal fatigue ability, traditional high adamite, half steel and high-chromium iron-cast roller be difficult
Meet and require.
The content of the invention
The present invention solves the technical problem of a kind of high abrasion roll is provided, it can solve the problem that existing roll is present upper
State defect.
In order to solve the above technical problems, one aspect of the present invention is：A kind of high abrasion roll is provided, wrapped
Include：High-chromium iron-cast roller body, plating are attached to the high-strength abrasion-proof layer of the rich chromium cast iron pressure roller external surface, and the high intensity is resistance to
At least 1 layer of layer is ground, the quality proportioning of its chemical composition included and each composition is：Carbon 0.21%-0.28%, silicon 0.1%-0.2%,
Manganese 0.5%-1.2%, nickel 0.02%-0.08%, chromium 0.8%-1.8%, zinc 0.5%-1.1%, remaining be iron and inevitable impurity.
In a preferred embodiment of the present invention, inevitable impurity content≤0.02%.
In a preferred embodiment of the present invention, the high-strength abrasion-proof layer has 1-3 layers.
In a preferred embodiment of the present invention, the gross thickness of the high-strength abrasion-proof layer is 0.6-2.4mm.
The beneficial effects of the invention are as follows：The present invention is resistance to by being attached to few floor height intensity in the plating in vitro of high-chromium iron-cast roller sheet
Layer is ground, makes the roll that there is excellent wearability, while composition and its proportioning by optimizing the high-strength abrasion-proof layer, make it
There is excellent resistance to high temperature oxidation and resistance against heat fatigue crack extended capability simultaneously.
