How Custom Graphite Parts Improve Efficiency in the Steel Industry

Steel production has never had a reputation for being clean or efficient. For over a century, massive blast furnaces consumed enormous amounts of coal and iron ore while belching CO2 into the atmosphere. But the steel industry has been changing, slowly but surely. Electric arc furnaces now dominate steel production in the United States, and the shift toward scrap recycling has reduced both energy consumption and emissions. At Semco, we've watched these changes closely because custom graphite parts play a significant role in making modern steelmaking more efficient. The electrical conductivity and thermal conductivity of graphite, along with its thermal...

Carbon Graphite: Sustainability and Green Manufacturing Practices

At Semco, we pay close attention to developments in synthetic graphite production, not just because we machine graphite components daily, but because our customers increasingly ask about sustainability. The truth is, graphite manufacturing has never been particularly "green." Synthetic graphite production consumes enormous amounts of energy, and the recycling of graphite has historically lagged behind other materials. As we’ve written about in a previous blog, we were called in to extract large graphite electrodes that had been disposed of in an Iowa cornfield. Yet we're seeing real changes in how graphite gets made and how it's being recovered and reused....

How Graphite Solutions Help Reduce Industrial Carbon Footprints

It's a funny thought, right, carbon graphite helping to reduce industrial carbon footprint, lower emissions, and combat climate change. To us at Semco, well acquainted as we are with graphite's stellar thermal management, durability, and key role in green technologies, the idea that carbon graphite plays a role in reducing emissions and industrial carbon footprint is not surprising at all. In fact, for years we've explored this topic in piecemeal ways in this blog (see this blog that includes how carbon graphite plays a part in hydrogen fuel cells, for instance). Here, we will take a look at the overall...
