Process stability, parts quality and shop floor productivity are must-haves for customers’ production of the graphite molds that are shaping the glass for today’s fast-moving information and communications technology (ICT) and automotive markets. New products—like high-end curved touch screens—require molded glass and drive the increasing need for machined graphite molds. The MILL S 400/500 GRAPHITE makes those impeccable 3D glass products—and more—possible. Graphite mold manufacturing for glass end products presents specific manufacturing challenges. They require ±5 µm precision, Ra 0.4 µm surface finish and, depending on the application, as many as 90 minutes of dry or wet machining—and they must be absolutely free from milling marks

The MILL S 400/500 GRAPHITE resolves these challenges. As ambient workshop temperatures fluctuate and machining speed changes, process stability is maintained, thanks to these solutions’ intelligent thermal management system and thermostabilized machine body. Precision and stability at the tool tip are ensured by the Step-Tec HVC140 Spindle, specially developed for best accuracy and fluid tightness. Its 42,000 rpm and 13.5 kW of power ensure the precision manufacturers need to tackle graphite molds, and it has thermal stability of less than 1.7 Kelvin around the machine support’s contacting surface. For mold makers looking to enter the market for molds for glass end products, both productivity and speed are important factors that can make a difference

Graphite machining has never been so attractive—and challenging. The Mikron HSM 500 GRAPHITE and MILL S 400/500 GRAPHITE yield the precise graphite electrodes that boost die-sinking EDM productivity and reduce costs

graphite electrodes for iron, steel & metal production

Graphite electrodes and nipples (connecting pins) are consumed primarily in electric arc furnace steel production, the steel making technology used by all “mini-mills.” Graphite electrodes are also consumed in the refining of steel in ladle furnaces and in other smelting processes such as production of titanium dioxide. 

Electrodes act as conductors of electricity in the furnace, generating sufficient heat to melt scrap metal, iron ore or other raw materials used to produce steel or other metals. The electrodes are consumed in the course of that production.

graphite electrodes for iron, steel & metal production

Electric arc furnaces operate using either alternating electric current (A/C) or direct electric current (D/C). The vast majority of electric arc furnaces use alternating current. Each of these furnaces typically uses nine electrodes (in three columns of three electrodes each) at one time. The other electric arc furnaces, which use direct current, typically use one column of three electrodes. The size of the electrodes varies depending on the size of the furnace, the size of the furnace’s electric transformer and the planned productivity of the furnace. In a typical furnace using alternating current and operating at a typical number of production cycles per day, one of the nine electrodes is fully consumed (requiring the addition of a new electrode), on average, every eight to ten operating hours. The actual rate of consumption and addition of electrodes for a particular furnace depends primarily on the efficiency and productivity of the furnace. Therefore, demand for graphite electrodes is directly related to the amount and efficiency of electric arc furnace steel production. 

Electric arc furnace steel production requires significant heat (as high as 5,000 degrees Fahrenheit) to melt the raw materials in the furnace, primarily scrap metal. Heat is generated as electricity (as much as 150,000 amps) passes through the electrodes and creates an electric arc between the electrodes and the raw materials. 

Graphite electrodes are currently the only products available that have the high levels of electrical conductivity and the capability of sustaining the high levels of heat generated in an electric arc furnace producing steel. Therefore, graphite electrodes are essential to the production of steel in electric arc furnaces. There is currently no commercially viable substitute for graphite electrodes in electric arc furnace steel making. The cost of graphite electrodes represents about 3% to 4% of the cost of producing steel in a typical electric arc furnace.
