Success Stories

USS Posco Steel employs industrial wireless solutions engineered by ESTeem

USS Posco Steel

USS-POSCO, the world’s most technologically advanced steel finishing plant, continues to increase production efficiency by recently updating their wireless control system.  A model for material handling and production efficiency, USS Posco provides 4,400 tons of finished steel products daily to 250 trucks and 12 railcars through an elaborate system of conveyors, automatic Coil Transport Vehicles (CTV), and overhead cranes.  The entire transport operation is monitored and controlled by Allen-Bradley PLCs linked through a wireless network.  A recent update of their radio network with state-of-the-art ESTeem Model 192 series wireless modems has allowed the Traffic Control computer to increase update times from the 10 CTVs and 2 overhead cranes nine fold.  This paper will overview the operation of the USS Posco system, describe how a PLC based wireless network was implemented and why Rockwell Automation and Electronic Systems Technology’s hardware fit within their modernization goals.

Bauxite mining operation that uses industrial radios

ALCOA Aluminum Production

Nothing has impacted the mobility in the 20th century like the discovery of how to effectively process aluminum.  Until just over 100 years ago, the production of aluminum was so cumbersome it sold for about the same price as silver, greatly restricting its use.  With advanced refining and smelting processes dropping the price of aluminum, this strong yet lightweight metal is now widely available for use in automotive and aerospace industries.

As the aluminum industry continues to grow, so does the competition.  The world’s first aluminum company, Aluminum Company of America (ALCOA), is still the leading producer of aluminum, but the competition has intensified in recent decades.  ALCOA has responded by perfecting processes, lowering costs, and increasing the technological base in all their plants. Efficiency in a large aluminum plant can only be accomplished by the efficient workings of the smaller systems within.  ALCOA’s Point Comfort, Texas Refining Plant has implemented several wireless control systems throughout the plant to provide a means to this efficiency.  Wireless modems have provided solutions for programmable logic controller (PLC) networks in areas otherwise inaccessible or too cost prohibitive to integrate.

Ethernet/serial radio application in a coke making facility

Coke Oven Control

This paper describes the implementation of a wireless communications network at a coke making facility.  The purpose of this network is to collect Charge, Leveling and Push cycle data from the machines used on a coke battery.  The data is electronically transferred to a VAX computer system to be compiled and trended.  To comply with EPA regulations.  At the facility, several coking ovens are constructed side by side into what is called a battery.  Each oven is approximately 2 feet wide by 22 feet high by 46 feet deep with three charging holes on top to allow coal to be dumped into the oven.  Doors are located on the front and back of the oven.  The front door has a smaller door near the top to allow access for the Leveler Bar (located on the Pusher).
