Application range of industrial aluminum guide roller: The aluminum guide roller is made of high quality aluminum material and is made by advanced processing technology. The surface is anodized HV300 (white) or HV700 (brown), the roll body finish is 0.8; the school balance G2 .5 grade; aluminum tube generally 8-10 reinforcing ribs; can be customized according to customer requirements, groove roller, cross line aluminum guide roller, center open wire aluminum guide roller, flower roller, anilox roller, cooling roller.
Aluminum alloy aluminum guide bar HV300, HV700 series. The air-expansion shaft roller is extruded with high-quality aluminum alloy. It has nine reinforcing ribs and 5cm wall thickness for strengthening. The wheel surface adopts new technology and the anode is hardened to ensure its rigidity and wear resistance. It is equipped with advanced Akshi computer balance. Correction, so that the balance is up to 2g, the above technology is currently the first in China. Using Taiwan's special tools and measuring tools, the surface roughness of the rollers is up to 0.8 and the coaxiality is 0.02mm. The reasonable shaft connection method can easily run freely and never change at any running speed. This product has high strength, low resistance, corrosion resistance, light weight, smooth rotation and no rust. It is the first choice in the printing machinery system.
The surface of the CNC lathe can be used to obtain the highest bonding strength and precision, good linearity and concentricity. The precise high-speed dynamic balance system can ensure static balance and high-speed dynamic balance performance (up to ISO1940 G1 level). To ensure that the aluminum roller runs at high speed on the machine without vibration, and different surface treatment methods can provide different use requirements. The aluminum roller produced by Yongzheng can greatly improve the performance of your machine.

(1) Universal white oxidized surface: moderate surface hardness HV300, low cost, can also provide different color surface (such as pure black) according to customer requirements, suitable for low tension film industry.
(C) Teflon surface: The special Teflon coating makes the ink easy to clean and provides moderate anti-stick properties.
(5) Industrial hard chrome surface: the highest surface hardness and corrosion resistance, the surface roughness of the gas rising shaft can be as low as Ra0.01 (ultra-mirror surface), compared with the traditional chrome-plated steel roller and the light-weight chrome-plated aluminum roller. Higher speed machines.
Graphite Electrode, mainly in petroleum coke, needle coke as raw material, coal tar pitch as a binder, calcined, ingredients, mixed kneading, pressure, roasting, graphitization, machining and made in the arc furnace in the form of arc The energy can be divided into ordinary power Graphite electrode, High Power Graphite Electrode and Ultra High Power Graphite Electrode according to its quality index.
Graphite electrode transport
1, graphite electrode in the long-distance transport to be covered with anti-rain Pengbu.
2, with lifting machinery unloading wooden box packaging electrodes, you must use the wire rope, not directly hook the electrode steel packing belt for lifting.
3, in order to protect the electrode end and thread, not directly with hook hook electrode hole hanging electrode.
4, loading and unloading joints box, you should gently take to prevent damage to the thread.
Second, the graphite electrode storage
1, the electrode should be stored in a clean, dry place; temporarily do not use the electrode and connector, do not remove the packaging, to prevent dust, debris fall into the thread or electrode hole, affecting product docking accuracy.
2, open field stacking electrodes, must be covered with rain pants. In the case of
3, the electrode in the Treasury storage to be placed neatly, the electrode stack on both sides to pad well, to prevent the cartoons.
4, bulk electrode stacking height is usually not more than 2.8 meters, the height of the box electrode should not be more than 4 layers.
5, the temperature of the place where the joints should be stored should not be too high to prevent the asphaltene joint bolt melting.
Third, the graphite electrode connection operation
1, by the wet electrode, before use to dry.
2, remove the spare electrode hole on the foam protective cap, check the electrode hole thread is complete.
3, with no oil and water compressed air cleaning spare electrode surface and hole thread; to avoid the use of wire or metal brush cloth cleaning.
4. Do not touch the threads in the electrode holes where the joint is carefully screwed into one end of the backup electrode (it is not recommended to insert the connector directly into the electrode that is replaced on the furnace).
5, the electrode spreader (recommended the use of graphite material spreader) screw into the other side of the electrode electrode electrode hole.
6, lifting the electrode, the mat soft objects to the bottom of the alternate electrode assembly to prevent the ground to break the joints; with a hook into the spreader after the lifting ring, lifting the electrode to be smooth, to prevent the electrode from the B-loose Off or collide with other fixtures.
7, the spare electrode hanging to the top of the electrode to be connected to the electrode hole slowly after the fall; rotating the backup electrode, so that the screw hook and the electrode with the rotation down; in the two electrode end distance 10-20mm, again with compressed air Clean the two ends of the electrode and the exposed parts of the joint; in the final complete discharge of the electrode, not too much, or because of violent collision, will lead to electrode holes and joints of the thread damage.
8. Tighten the backup electrode with a torque wrench until the ends of the two electrodes are in close contact (the correct connection of the electrode and the connector is less than 0.05 mm).
Fourth, the graphite electrode in the use of the precautions
1, the electrode holder should be caught in the top of the cord outside the cordon, otherwise easily lead to electrode break. The contact surface of the gripper and the electrode should always be cleaned to maintain good contact with the electrode, and the gripper cooling water jacket should be kept leaking. In the case of
2, the electrode connection found cracks exist to identify the cause, to eliminate the gap before use.
3, connecting the electrode, found that the phenomenon of joint peeling off, to fill the joints and then connect the bolt.
4, the electrode should be used vertically, to avoid tilting operation, in particular, can not be connected to a group of electrodes placed horizontally, so as not to break.
5, to the furnace into the charge, the bulk material should be installed near the bottom of the furnace to reduce the collapse of the large pieces of charge impact electrode.
6, smelting, should avoid a large number of insulation material stacked in the electrode just below, so as not to affect the use of electrodes, or even electrode break.
7, the electrode in the rise or fall, should avoid touching the lid, resulting in electrode damage.
· 8, in the smelting site, to avoid slag splashing to the site of the electrode or connector threaded buckle, damage the thread accuracy.
