Abstract
The invention provides a ceramic paper pressing roll. The ceramic paper pressing roll comprises a steel base, wherein a nickel-chromium alloy coating is coated outside the steel base; and a chromium sesquioxide coating is coated outside the nickel-chromium alloy coating. The ceramic paper pressing roll of the invention has high corrosion resistance. The chromium sesquioxide coating on the surface layer has hardness of over 1,200HV and extremely high wear resistance. The service cycle of one ceramic paper pressing roll is about 5 times that of a normal marble roll.
Description
Technical field
The present invention relates to a kind of machinery, relate in particular to a kind of ceramic paper pressing roll.
Background technology
The air roll of prior art is the Dali stone roll of the about 600mm of diameter, about hardness 800HV.Owing to limited by hardness, appearance in use is not wear-resisting, and month needs are gone up grinding machine and ground once.Cause thus that production efficiency is low, percent defective is high.Because specification is bigger, often up-down rollers causes the significant wastage of human resources simultaneously.
Summary of the invention
Purpose of the present invention exactly in order to address the above problem, provides a kind of ceramic paper pressing roll.
In order to achieve the above object, the present invention has adopted following technical scheme: a kind of ceramic paper pressing roll, comprise steel substrate, and outside steel substrate, be coated with one deck nichrome coating, outside the nichrome coating, be coated with one deck chrome green coating.
The thickness of described nichrome coating is 0.12-0.15mm, and the thickness of described chrome green coating is 0.25-0.35mm.
Described nichrome coating and chrome green coating adopt plasma spraying technology to form respectively.
Nickel content in the described nichrome is 75%-85%.
Ceramic paper pressing roll of the present invention is owing to be coated with two-layer plasma sprayed coating outside steel substrate, thereby has extremely strong anticorrosive and antiwear property.The life cycle of a ceramic rotor approximately is more than 5 times of common Dali stone roll.Save material and manpower greatly, obviously improved production efficiency.
Description of drawings
Fig. 1 is the cross-sectional structure schematic diagram of ceramic paper pressing roll of the present invention.
The specific embodiment
Referring to Fig. 1, ceramic paper pressing roll of the present invention comprises steel substrate 1, is coated with one deck nichrome coating 2 outside steel substrate, is coated with one deck chrome green coating 3 outside the nichrome coating.Nichrome coating and chrome green coating adopt plasma spraying technology to form respectively.The thickness of nichrome coating wherein is 0.12-0.15mm, and the thickness of chrome green coating is 0.25-0.35mm, preferably 0.3mm.Nickel content in nichrome is 75%-85%.
Ceramic paper pressing roll of the present invention has very strong resistance to corrosion.The chrome green coating hardness on top layer is up to more than the 1200HV, and abrasion-resistance is extremely strong.
Claims (4)
1. a ceramic paper pressing roll comprises steel substrate, it is characterized in that: be coated with one deck nichrome coating outside steel substrate, be coated with one deck chrome green coating outside the nichrome coating.
