In last month’s currents, we learned about the Circle of Slag and how this scrap metal recycling process is an important part of the Port’s operations. For this month, we are going to learn about how slag is created.
Slag’s journey starts in the smelting process. This procedure separates steel from its impurities, these impurities are called steel slag and are a valuable construction material. During this process, slag is heated to over 2570 degrees Fahrenheit and creates a molten liquid melt. This melt is made up of silicate, a salt that contains silicon and oxygen, and metal oxides, a chemical compound formed between metals. Once this is cooled and solidified, the slag is formed into various shapes and sizes depending on its final use. And, with that, the slag is ready to be used to help strengthen construction projects such as bridges and roads!
To learn more about the slag process, check out the Port’s website for more details.
