Happy new year
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.

The year is approaching, and it is time to return home for the holidays. The bus stations and train stations in Foshan City serve as round-trip transportation hubs with large numbers of people. They are also places where burglary and fraud cases occur frequently. Criminals choose foreigners as the targets of the crime. Take out the property of foreigners by means of health certificate. The Foshan Public Security Bureau issued a security precautionary reminder, hoping that everyone will be able to spend a good year in peace.
[Pick up and split the scam]
Suspect characteristics: There are two women and one man, two men and one woman, three men and one woman, or two men and two women, and the gang members are around five.
Method of committing crimes: There are different ways to defraud the property of foreigners by dropping the package, and then take the passbook or the password of the credit card and take the deposit.
The police reminded that those returning to their hometowns should raise their awareness of self-prevention, do n’t be greedy for petty gains, and avoid being fooled. The case should be reported in time so that the public security organs can take targeted measures to conduct investigations.
[Fraud Driver Fraud]
Target of the crime: Passengers who need to transfer to other places after arriving at the bus station.
The characteristics of the suspect: generally a motorcycle driver.
Method of committing crimes: Using foreign travellers who are not familiar with the characteristics of Foshan, to defraud the victim's cash and mobile phone on the pretext of requiring a deposit or certificate.
The police reminded that the majority of migrant workers should not easily believe strangers, and do not need to apply for a health certificate when travelling by car or returning home.
[Buying (changing) ticket fraud]
Target of the crime: Passengers who "buy and exchange tickets" at the station.
Method of committing crimes: In the name of the station staff, it is said that there are ways to help them buy and exchange tickets, wait for opportunities to defraud, and run away.
The police reminded: The majority of people who return home for the Spring Festival should pay attention to distinguishing station staff. Station staff wear special work clothes, and the work area is limited to the station. If necessary, you can consult the police on duty.
ã€Anti-theft reminder when traveling by car】
When buying a ticket, remember to keep your backpack in sight. There are many people at the ticket gate, passengers must not relax their vigilance. Passengers should arrange their luggage before leaving, and put their mobile phones, money, etc. in a safe and personal position.
In the carriage, thieves often sit on the side or behind the passenger seat; in the carriage, be particularly alert to people who deliberately push and lean against themselves.
