Transition From “Koppers Minus 10” to “Odd-Even” Pushing Schedule at DTE Shenango Coke Battery
Michael W. Shafer (left), technology engineer, and Robert H. Carlin (right), technology engineer, DTE Energy Services, EES Coke Battery, River Rouge, Mich. (shaferm@dteenergy.com, carlinr@dteenergy.com)
The “Koppers minus 10” pushing schedule at DTE Shenango would not allow time for repair work without significant delays or production loss. This paper summarizes the rules and methodology for transition to the “odd-even” schedule, which creates extended periods of time for necessary renovations. |

Predictions of Blast Furnace Hearth Corner Erosion Profile
D. (Frank) Huang (left), staff engineer — process research, ArcelorMittal Global R&D, East Chicago, Ind. (frank.huang@arcelormittal.com); Lijuan Zheng (center) and Chenn Q. Zhou (right), professor and department head, Mechanical Engineering Department, Purdue University Calumet, Hammond, Ind. (qzhou@calumet.purdue.edu)
With a new algorithm and methodology, a 3-D model predicts the hearth corner inner profile efficiently and accurately. The model is also able to predict the inner profiles of all different types of blast furnace hearths. |

Comparing the Accuracy of Acousto Ultrasonic-Echo (NDT), Finite Element Analysis (FEA), and Drilling When Obtaining a Blast Furnace Refractory Lining Wear Profile
Afshin Sadri (top left), global director, NDT Group, Pawel Gebski (top right), NDT specialist, and Alan Rampersad (bottom left, formerly NDT technician), Hatch Ltd., Mississauga, Ont., Canada (asadri@hatch.ca, pgebski@hatch.ca); Pablo Marinelli (bottom center), refractory technology, and Enrique Doro (bottom right), technology, Ternium Siderar, Buenos Aires, Argentina (pmarinelli@ternium.com.ar, edoro@terniumsiderar.com)
During its 11-year campaign, Ternium Siderar’s No. 2 blast furnace experienced severe hearth bottom wear. The results of two Acousto Ultrasonic-Echo (AU-E) NDT surveys, along with FEA methods, were compared to drilled samples, and used to monitor and improve the condition of the refractory lining. |
