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:What are the structures of pyrolytic graphite electrodes? What are their properties and applications? We hope that some details will not be found
The high purity graphite component is put into the furnace, and nitrogen and methane are produced under vacuum high temperature. Then graphite is shown to produce 10% coating.
Q:MITSUBISHI machine graphite electrode processing, how does not accumulate carbon?
The three is difficult cold start, is sparking difficult, not easy car, and finally the combustion chamber carbon Yan will cause a heavy cylinder knock, low speed and acceleration noise, causing damage to the piston and crankshaft, causing the engine temperature which can seriously affect the automobile safety. Emission standards exceeded, not only through the annual inspection, but also directly aggravate the pollution of the environment
Q:Graphite is made of high-strength graphite, it is a kind of graphite grade specification.
Most of the graphite electrodes are cylindrical, but also have square and multi ribbed shapes. Graphite blank refers to the firing of raw materials without processing graphite.
Q:Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?
Petroleum coke is divided into needle coke and sponge coke and projectile reef, fixed carbon content components of petroleum coke is around 80%
Q:How long is the graphite electrode machining cycle?
When the cut depth is less than 0.2mm, the graphite will break down very little, and the surface quality of the side wall will be better.
Q:Why is graphite a negative pole and copper is an anode?
Graphite, as an electrode material, can conduct electricity, which belongs to an inert electrode. It only acts as a conductive agent, but does not participate in the electrolytic reaction process. So the anode is made, and copper is oxidized in the electrolysis of monovalent cations, so copper is used as the anode.
Q:Graphite powder produced by graphite electrode and what we usually call graphite is a kind of thing?
Coal tar pitch as binder is made by calcination, batching, kneading, pressing, roasting, graphitization and machining
Q:Is the anode of electrolytic water suitable for ordinary titanium wires?
Graphite firstFirst of all, the titanium electrode is usually not pure titanium, it should be titanium with a metal oxide coating. Secondly, the advantages of the titanium electrode is mainly to save electricity, the corrosion resistance of carbon is much stronger than that of industrial production, if the meaning is relatively large, but it is still in laboratory experiments, electrolysis of water, not what meaning.
Q:Carbon graphite electrode and what is the difference?
The material is composed of carbon carbon, but without graphite, after molding sintering temperature is only more than 1000 degrees, no graphitization.
Q:The production of one ton of steel required graphite electrode
The consumption of graphite electrode in steelmaking in arc furnace, according to the different material, different specifications of graphite electrode used (normal power graphite electrode, high power graphite electrode, ultra high power graphite electrode) have relations.
