Scrap steel is melted in a crucible, induction, electric arc or reverberator furnace at 1500° C or 2700°F. The required alloys carbon and silicon, and flux to bind to impurities to create slag are added to the molten iron. The slag is lighter than iron and floats to the top from where it is removed. The molten iron is then poured into a metal ladle with a long handle which is then carried to the sand molds contained in the metal frames and poured through the riser. Green sand has a lower auto-ignition temperature than the temperature of the molten iron allowing the organic material present in the sand to use up all the oxygen present in the mold, preventing oxidation of the manhole cover. Trapped gasses can cause bubbles in the casting.
One of the primary advantages of metal bike rack stands is their durability.
