Galvanizing Process. Hot-dip galvanizing is the process of immersing iron or steel in a bath of molten zinc to produce a corrosion resistant, multi-layered coating of zinc-iron alloy and zinc metal. While the steel is immersed in the zinc, a metallurgical reaction occurs between the iron in the steel and the molten zinc.

Direct reduced iron (DRI) is the product which is produced by the direct reduction of iron ore or other iron bearing materials in the solid state by using non-coking coal or natural gas. Processes which produce DRI by reduction of iron ore below the melting point of the iron are normally known as the direct reduction (DR) processes.

Electric Arc Furnace Process. As the name implies, the process uses an EAF to melt the charge to make steel. It is a batch melting process producing batches of molten steel known as heats. The EAF operating cycle is called the tap-to-tap cycle and is made up of the following operations: 1. Furnace charging.

This blast furnace process is the oldest but still the main method to produce large quantities of molten raw iron, hot metal, and for steel making and foundry purposes.
Overview of the steel production process. Steel is principally made via two routes, the last Furnace-Basic Oxygen Furnace (BF-BOF) route and the Electric Arc Furnace route (EAF) - often referred to as the 'primary' and 'secondary' paths. The former is used to create new or '' steel, the latter is often used to recycle steel scrap.
How steel is made. First, the raw materials, either iron ore or scrap iron (depending on the process), are converted into molten steel. The ore-based process uses a blast furnace or smelter and the scrap-based process uses an electric arc furnace. Next, the molten steel is poured and solidified in a continuous caster.

Blast Furnace Process. The blast furnace is a counter-current gas/solids reactor in which the descending column of burden materials [coke, iron ore and fluxes/additives] reacts with the ascending hot gases. The process is continuous with raw materials being regularly charged to the top of the furnace and molten iron and slag being tapped from ...
