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 is the role of the Pt electrode? What is the difference between the graphite electrode and the graphite electrode?
- This kind of stable material because of the chemical properties is stable, is often used as a counter electrode. The electrode is composed of circuit and the working electrode by current.Pt electrode, carbon electrode are inert electrode, relatively stable, can be used as the electrode.
- Q:Where is the graphite electrode scrap?
- Atoms, ions, and electrons collide with each other in strong oscillatory motion to produce more electrons and ions.
- Q:What is the striking electrode in the die making? Where is the technical point?
- Electrical discharge machining (EDM) is a spark discharge in a liquid medium at a lower voltage range to meet the required shape and size.
- Q:Use of graphite in steelmaking
- Graphite can be used as an agent for carburizing in the steel making industry. Carburizing uses a wide range of carbonaceous materials, including synthetic graphite, petroleum coke, metallurgical coke, and natural graphite. Worldwide, the use of graphite for carburizing is still one of the main uses of earth like graphite.
- Q:Electrolysis of CuCl2 solutions with graphite electrodes
- After energization, electrolysis occurs, not ionizationIonization does not require energization, and can occur in aqueous or molten state.
- Q:The use of graphite as an electrode in alumina electrolysis
- The technical knowledge of electrolytic aluminum, cleaning and maintenance of alumina equipment, you can search for Baidu on the green, looking for.
- Q:What is the application of wire cutting with graphite electrode?
- Greatly shorten the preparatory time of mechanical processing, and improve the level of automation of the whole process of machining, and also enhance the ability of the manufacturing system to adapt to changes in production conditions.
- Q:Carbon graphite electrode and what is the difference?
- The difference between graphite electrode and carbon is mainly composed of graphite manufacturing, the latter for carbon materials,
- Q:The production of one ton of steel required graphite electrode
- Not sure, look at your such as what is charge, and your smelting level.If the proportion of molten iron to the furnace is high, then the electrode consumption is low, 0.7kg/t, or lower. If it's cold, 1-2kg/t.
- Q:The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?
- Use oil cold. Air cooling will cause graphite dust flying, on the one hand, toxic, on the one hand there are security risks (caused by circuit short circuit). Water cooling is virtually out of use, taking into account the maintenance and maintenance of the CNC.
