Hot rolled steel has been roll-pressed at high temperatures (over 1,700Ë F), which is above the re-crystallization temperature for most steels. This makes the steel easier to form, and also high quality long duration time cold rolled grain oriented sSouthern Small Grains Resource Management Handbook High quality, professionally grown and conditioned small grain seed should have below 2 percent inert matter. Other crop In some instances the other crop may be a weed in small grains, but an economically important crop in another planting environment (i.e., ryegrass, cheat, clover or canola).Steps in the Modern Steelmaking ProcessJan 14, 2020At high temperatures, oxygen is blown through the metal, which reduces the carbon content to between 0-1.5%. The EAF method, however, feeds recycled steel scrap through high-power electric arcs (with temperatures of up to 1,650 degrees Celsius) to melt the metal and convert it into high-quality
