Abstract
The invention relates to a corrugator roll surface processing structure, which comprises a body, wherein a layer of metal tungsten carbide coating is formed on the surface of the body. The structure has the advantages of avoiding causing environmental pollution by hard chromium plating like hard chromium plating corrugator roll and greatly prolonging the service life of the corrugator roll.
Description
Technical field
The present invention relates to a kind of corrugation roller, relate in particular to the surface treatments of this corrugation roller.
Background technology
The corrugation roller in use, because paper constantly slips over corrugation roller tooth top and produces friction, make corrugation roller generation wearing and tearing and cause producing defective corrugated board, influenced the service life of corrugation roller, so the corrugation roller of high life needs corrugation roller tooth surface to have very high hardness and anti-wear performance (with reference to QB/T2498-2000 industry standard 4.2.12).
The durionise processing is mainly carried out on corrugation roller surface at present, durionise is to be the electrolyte of Main Ingredients and Appearance with chromic acid and sulfuric acid, the utilization electroplating device utilizes electrolysis to make the technology of corrugation roller surface attachment layer of metal chromium, and is good extensively for making the use of corrugation roller than high-wearing feature because of low cost of manufacture, technology are simple relatively, hard chrome has hardness.
But the problem that corrugation roller surface electroplating hard chrome exists: the one, ambient influnence, when durionise, chromic acid has higher emission capabilities and covering power, make in the surrounding air chromic acid concentration higher, the grievous injury people are healthy, and multiple diseases such as perforation of nasal septum, skin ulcer, skin class can take place in long-term contact, influence 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 HV900～1050, generally the surface heat processing is more durable on the corrugation roller though be used in, and the life-span of corrugation roller under normal circumstances can be produced 8,000,000 long meter corrugated boards, but still can not satisfy the carton production demand of present high speed development.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of surface treatments of corrugation roller, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: body; Surface coverage layer of metal tungsten carbide coating at described body.
Compared with prior art, the invention has the beneficial effects as follows: solved the environmental pollution that durionise corrugation roller causes because of durionise, improved simultaneously corrugation roller service life greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the device structure schematic diagram that the present invention is handled.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
As seen from Figure 1: the present invention includes: body 2; Surface coverage layer of metal tungsten carbide coating 7 at described body 1;
The thickness of described metallic carbide tungsten coating 7 is between 0.05～0.1mm.
As seen from Figure 2: tungsten-carbide powder 6 carries out heat fused by spraying equipment control system 5, utilize the equipment self dynamical system through spray gun 3, with 2200m/s speed powder molten drop 4 is ejected into corrugation roller 2 surfaces, surface at the corrugation roller that rotates forms layer of metal tungsten carbide coating 7, and whole process is finished in control room 8 that isolates and operating room 1!
Design of the present invention is to utilize the method for thermal spraying that the tungsten-carbide powder fusing is injected into corrugation roller surface, be different from traditional corrugation roller and hard chrome be coated in corrugation roller surface with electro-plating method, because the tungsten carbide metal powder can not produce aerosol and finish in the separate space of a sealing, therefore can be to environment generation pollution with to the human injury, and because the hardness of tungsten carbide reaches more than the HV1400, normal use can be produced the above cardboard of 3,000 ten thousand long rice, its hardness and wearability are higher than hard chrome far away, improve the service life of corrugation roller greatly, satisfied the requirement that carton enterprise uses the corrugation roller.
Claims (2)
1. the surface treatments of a corrugation roller comprises: body; It is characterized in that: at the surface coverage layer of metal tungsten carbide coating of described body.
2. the surface treatments of corrugation roller according to claim 1 is characterized in that: the thickness of described metallic carbide tungsten coating is between 0.05～0.1mm.
