FAQ

①How about your company？

A world class manufacturer & supplier of castings forging in carbon steel and alloy steel，is one of the large-scale professional investment casting production bases in China,consisting of both casting foundry forging and machining factory. Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customer’s requirements.

②How to guarantee the quality of the products？

We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

Q: Why is graphite conductive electrode oxidized?: Coal tar pitch is a kind of high temperature resistant graphite conductive material, which is made of coal tar pitch as binder. It is made by calcination, crushing, mixing, kneading, forming, roasting, graphitization and mechanical processing. It is called graphite electrode

Q: What are the factors affecting the service life of graphite electrode in ultra high power arc furnace?: China's graphite electrode quality standard (YB/T4090-2000) to evaluate the quality of the ultra high power graphite electrode is defined 6 physicochemical indexes, including resistivity, flexural strength, elastic modulus, bulk density and linear expansion coefficient as the quality evaluation index, ash as a reference index.

Q: What is the reason that the current cannot be increased when the graphite electrode is used for anode electrolysis?Add calcium chloride and sodium bicarbonate into electrolytic water: Because in the process of electrolysis of water in cathode electron generated hydroxyl, the alkaline solution increased. But with the hydroxyl reaction of sodium carbonate and sodium bicarbonate, carbonate and calcium ions exist at the same time, must produce the precipitation of calcium carbonate, the ion in the solution is reduced, thereby conductive resistance increases. Thus weakened over time current cannot be raised

Q: What is the graphite furnace electrode with a diameter of 400?: With the development of EAF steelmaking technology, the steel-making technology is developing towards large scale and ultra high power. The graphite electrode is mainly made of large size graphite electrode and ultra high power graphite electrode.

Q: Will the concentration of electrolytic sodium sulfite be increased with graphite as electrode?: Not alwaysIt depends on the rate of electrolyzed water or the rate at which sodium sulfite is oxidized.

Q: Can high-purity graphite be used as an electrode?: High purity graphite can be used as electrode, high purity graphite as electrode has many advantages. According to the research of Qingdao Huatai graphite, we can see: 1, high purity graphite electrode is quick in opening and good in air permeability;

Q: How can the graphite powder be processed into high quality carburizing agent? Thank you: Basically, it can no longer be a "good" carburizing agent

Q: Why is graphite a negative pole and copper is an anode?: Electrolysis (Electrolysis) is the current through the electrolyte solution or molten electrolyte (also called electrolyte), caused by the redox reaction in the cathode and the anode, the electrochemical cell can occur when an external DC voltage in the electrolysis process.

Q: I remember the more lively metal, the electron?: C metal is copper, because a dilute sulfuric acid into the H2 precipitation, then definitely not copper. And the inactive first precipitate

Q: How large is the permissible overload current per square millimeter of the graphite electrode cross section?: The safe current is decided according to the conductor wire cooling conditions, cooling conditions, the overhead line package, an insulating layer and bare, cooling conditions are also different.
