What is impregnation and which carbon materials need to be impregnated?
Impregnation is the process of placing carbon materials in a pressure vessel and forcing liquid impregnant (such as bitumen, resins, low-melting metals and lubricants) to penetrate into the pores of the product under certain temperature and pressure conditions. Carbon materials that need to be im...Read more -
GRAPHITE ELECTRODE IS MAINLY DIVIDED INTO SEVERAL TYPES
(1) Natural graphite electrode. Natural graphite electrode is made of natural flake graphite as raw material. In the natural graphite to add coal asphalt, after kneading, molding, roasting and machining, you can prepare natural graphite electrode, its resistivity is relatively high, generally 15~...Read more -
WHAT ARE THE MAIN APPLICATIONS OF GRAPHITE ELECTRODES?
(1) For electric arc steelmaking furnace. Electric furnace steelmaking is a large user of graphite electrodes. Electric furnace steelmaking is carried out by using graphite electrode to conduct human current into the furnace and the high temperature heat source generated by the arc between the el...Read more -

HOW ARE GRAPHITE ELECTRODES CONSUMED IN EAF STEELMAKING?
The consumption of graphite electrodes is mainly related to the quality of the electrodes themselves, but also to the steelmaking operation and process (such as the current density through the electrodes, the smelting steel, the quality of scrap steel and the oxygen duration of the block friction...Read more -
WHAT MATTERS SHOULD BE PAID ATTENTION TO WHEN USING GRAPHITE ELECTRODE IN ELECTRIC STEEL MILL
(1) Select the appropriate electrode variety and diameter according to the capacity of the electric furnace and the transformer capacity equipped. (2) In the loading and unloading of graphite electrodes and storage process, pay attention to prevent damage and moisture, moisture electrode should b...Read more -
What are the quality requirements of graphite electrode for DC arc furnace?
The graphite electrode used in DC arc furnace has no skin effect when the current passes through, and the current is evenly distributed on the current cross section. Compared with AC arc furnace, the current density through the electrode can be appropriately increased. For ultra-high power electr...Read more -
