Steel mills, or steelworks, are industrial plants used to manufacture steel. These steel manufacturing plants typically smelt down iron and carbon, mixing the two together to create steel, though integrated steel mills also perform a variety of other metalworking processes like converting iron ore to molten iron, performing metal casting, product rolling, billet rolling, and more.
An integrated steel mill is not cheap to build. In fact, companies generally spend between $1 billion to $4 billion to build them. While this might seem like a lot, it can be a smart investment due to the strong global demand for metal and high-profit margins.
Brief history
Steel manufacturing was pioneered by an English inventor named Henry Bessemer in the mid-1800s. He developed a process for creating steel by forcing air through molten iron, known as the Bessemer process. This process allowed faster and more proficient production of steel but has since been replaced by more efficient processes.
Statistics show that steel manufacturing took off in the United States in the early 20th century. In 1875, U.S. steel mills produced 380,000 tons of steel, but by 1920 U.S. steel mills were producing more than 60 million tons.
Integrated steel mills
The main raw materials required for an integrated mill are iron ore, limestone, and coal. These materials are put into a blast furnace where the iron compounds in the ore give up excess oxygen and become liquid iron. The accumulated iron is tapped from the blast furnace and directed to other vessels for further steel-making processes. Although historically the Bessemer process was used for the production of economical steel, it has now been entirely replaced by basic oxygen furnaces or other processes.
Molten steel is cast into large blocks called blooms. During the casting process, integrated steel mills may use various methods, such as adding aluminum, so that impurities in the steel float to the surface and can be cut off the finished bloom.
Primary steel-making plants will operate on a continuous production campaign lasting several years due to the high cost of energy and structural stress associated with heating and cooling a blast furnace. Even when demand for steel is low, it may not be feasible to shut down production, typically steel mills slow down the production rate rather than allowing the blast furnaces to cool.
The final steel products made by an integrated mill are usually large structural sections, heavy plate, strip, wire rod, railway rails, and long bars or pipe.
The importance of security and surveillance
Video surveillance is a smart way to enhance the efficiency, safety, and effectiveness of manufacturing operations at steel mills. With integrated security cameras, door access control, and smart sensors, steel mill managers can strengthen and simplify their approach to health, safety, and security.
Some of the benefits of security and surveillance for steel mills are:
Monitor Remote Facilities: For steel mill operators who manage multiple sites, security cameras with remote access are indispensable tools for remote management.
Mitigate Risks and Hazards: A steel mill involves a lot of high temperatures and dangerous processes. Surveillance is a great way to keep a close eye on whether safety precautions are being properly followed by steel mill workers.
Maximizing production: Video footage can be used to visualize the current state of operations, document continuous improvement, and identify opportunities to optimize productivity.
Monitor shipments and inventory: Video surveillance is also used to ensure the safe arrival and storage of inventory, raw materials, parts, and other products. Not to mention you can track and safeguard raw materials and other inventory and receive notifications when there are any deliveries or movement around sensitive areas.
Monitor and deter intruders: Protection from physical intrusions is critical to loss prevention. Security cameras and access control can provide alerts that aid in protecting your stock, important machinery, or other expensive items.
Top Cities for Steel Mills in the United States
In 2014, the United States was the third-largest producer of raw steel in the world, after China and Japan. The industry produced 29 million metric tons of pig iron and 88 million tons of steel. Most iron and steel in the U.S. are made from steel scrap rather than iron ore.
149,000 people were employed in iron and steel mills in 2014, producing $113 billion in steel. That means about 0.3% of the United States population is employed by the steel industry.
