• Pig iron

    Pig iron, also known as crude iron, is an intermediate product of the iron industry in the production of steel which is obtained by smelting iron ore in a blast iron has a very high carbon content, typically –%, along with silica and other constituents of dross, which makes it very brittle and not useful directly as a material except for limited appliions.

  • What Is Involved in Pig Iron Production? (with pictures)

    Pig iron production is generally only one step in the creation of a finished iron product, since the high carbon content of iron in this form makes it mostly unusable. To make it more versatile, it can be melted again and mixed with slag, creating wrought iron, or combined with additional iron ore and alloys to create cast iron.

    The nation during this period was producing 40 million tons of pig iron a year with a concomitant output of 20 million tons of slag. At the same time, another problem the companies were facing, particularly during the latter part of 1917, was the car shortages for hauling slag due to the heavy demands for freight shipments to serve the war effort.

  • How is LD slag produced?

     · Liquid LD slag is produced during the LD process as pig iron is processed into crude steel. Slag is not a random product, but rather a consequence of the LinzDonawitz process, which uses steel as well as LD slag. The slag is separated from the crude steel, separately processed, and its chemical composition analyzed.
