Description
Technical field
The utility model relates to a kind of Corrugator roller, specifically a kind of ferrous alloy powder coating Corrugator roller.
Background technology
In use, because fluting medium is between Corrugator roller during compacting by rolling, body paper slips over the tooth crest of stupefied tooth to Corrugator roller, has relative motion, has wearing and tearing to tooth crest.Wear factor has three, one be on body paper contained mineral matter with body paper in tooth top friction mistake; Two are on body paper the institute rigid particulate such as fine sand, the dust etc. that are mingled with, embed acts on " acupuncture " of Corrugator roller tooth surface; Three be empty wagons run or break paper time, the two corrugated roller flank of tooth directly contacts, and causes the very stiff and demanding linear higher pair contact of metal to metal.The failure modes such as three constitutes the stupefied tooth surface spot corrosion of Corrugator roller, peels off, blind crack.Therefore the stupefied tooth surface of Corrugator roller should meet bright and clean, superhard, wear-resisting etc. the requirement in surface, and therefore the surface treatment of Corrugator roller has become the long-term and difficult task of Corrugator roller manufacturing enterprise one.
Current Corrugator roller surface treatment mainly contains following two kinds: 1, surperficial intermediate frequency heat treatment+electroplate hard Cr; 2, surperficial intermediate frequency or Compound Heat Treatment+sprayed wc.
The electrolyte that the first durionise is is Main Ingredients and Appearance with chromic acid and sulfuric acid, uses electroplating device to utilize electrolysis to make the technique of Corrugator roller surface attachment layer of metal chromium; There is following advantage:
(1), relatively simple, the hard chrome of low cost of manufacture, technique has hardness comparatively high-wearing feature is good.
(2), surface roughness Ra reaches 0.1, and working tension is little, adapts to microwatt stupefied (tooth depth is lower than 1.0mm) production, requires low to Corrugator roller body paper bursting strength index.
Therefore widely use at micro-currugated board production line and some low-grade board production; But Corrugator roller electroplating surface hard chrome Problems existing: is ambient influnence; when durionise; chromic acid has higher emission capabilities and covering power; make chromic acid concentration in surrounding air higher; grievous injury people are healthy, and the various diseases such as perforation of nasal septum, skin ulcer, skin can occur Long Term Contact, affect surrounding enviroment simultaneously; environmental pollution is very serious, is one of project of state key prevention and control; They are two years old, the hardness of chromium plating is between HRC65 ~ 75, although it is more durable to be used in more general Surface heat-treatent on Corrugator roller, the life-span of Corrugator roller can produce 8,000,000 long meter corrugated boards under normal circumstances, but still can not meet the carton Production requirement of current high speed development.
The second tungsten carbide Corrugator roller utilizes the method for thermal spraying that tungsten-carbide powder fusing is injected into Corrugator roller surface, forms metallic carbide tungsten coating.There is following advantage:
(1), be different from plating Corrugator roller electro-plating method and hard chrome is coated in Corrugator roller surface, can not aerosol be produced due to tungsten carbide metal powder and complete in-individual closed separate space, therefore can not to environment generation pollution with to human injury, and because the hardness of tungsten carbide reaches more than HV1400, normal use can produce the above cardboard of the long rice of 300O ten thousand, its hardness and wearability, far away higher than hard chrome, substantially increase the service life of Corrugator roller, meet the requirement that Carbon enterprise uses Corrugator roller.
(2), more durable than the general Corrugator roller life-span 3 ~ 6 times of tungsten carbide Corrugator roller.
(3), the change of general Corrugator roller tooth depth greatly, Quality of Board instability, during new roller, core paper and glue spreader gap should be 0.1mm ~ 0.2mm; but wearing and tearing 0.1mm in the middle of Corrugator roller; gap will expand, thus causes too much glue amount, and too much moisture content makes cardboard soft and easy prying; The change of tungsten carbide Corrugator roller tooth depth is little and permanent, and it is straight stable that quality pulled by paper.
(4), in the middle of general Corrugator roller, wearing and tearing are excessive; become concave; cannot the cardboard of the wide door width of regenerative ratio; produce waste paper; because two ends can be crushed or centre not paste (foaming of coming unstuck); at this time you are obliged to go the two ends of mixing roll, to walk wide cut cardboard, to maintain the life-span of Corrugator roller; Tungsten carbide Corrugator roller because wear-resisting, the broadsheet and having problems of going further after there is not narrow paper.
(5), general Corrugator roller because quick abrasion, so original design tooth depth is compared with high (stupefied rate is large), to ensure the life-span; Tungsten carbide Corrugator roller because wear-resisting, design at the very start compared with low tooth depth (stupefied rate is little) and the life-span permanent.
(6), general Corrugator roller can not be stupefied by V-type, if will be worn very soon because stupefied top is little, cardboard can be more and more softer; Just this problem is there is not in tungsten carbide Corrugator roller because of wear-resisting.
(7), general Corrugator roller tooth top quick abrasion and many, after repairing, diameter is just much little; Tungsten carbide Corrugator roller is because wear-resisting and wearing and tearing and few, and after repairing, diameter is almost constant.
But tungsten carbide Corrugator roller also has following shortcoming simultaneously: the surface roughness Ra 3 ~ 41, after spraying, after special polishing, generally also at 0.6 ~ 0.8 micron, be not suitable for using at trickle corrugated paper board production line, easily cause shredded paper; 2, cost is high, and for some low speed corrugated paper production line or single-side machine, cost performance is low.
Summary of the invention
