Chemical
coal flow aids can provide many benefits to coke plants, including
improved production rates, reduced maintenance and lower cleaning
costs. This article discusses the mechanisms by which coal
flow aids function and analyzes several successful case histories. |
Resolving
Overhead Crane Skew Problems — A Simplified, Field-proven
Approach
Thomas C. Lindstrum, product manager,
Morris Material Handling – P&H, Oak Creek, Wis. (tlindstrum@morriscranes.com)
This article reviews the mechanical problems and related causes
of crane skewing. A simplified approach to the overall problem
is discussed, along with methods that have been used to successfully
and economically resolve it. Various crane wheel designs and
bridge drive arrangements are compared. |

and Michael A. Urbassik, product line manager — crane
products, Eaton Electrical, Milwaukee, Wis. (michaelaurbassik@eaton.com)
New
technology often requires paradigm shifting, which many are
reluctant to undergo. This paper discusses some of the paradigm
changes caused by the implementation of new DC-to-DC technology
as applied to electric overhead cranes.

Point, Md. (ahamm@intlsteel.com)
The
strip slab inventory management system is a fully integrated
inventory management system from order entry to slab application
and hot mill scheduling. The system not only helps in completing
customer orders, but it also minimizes slab hauler moves and
minimizes overgrading of steel. |

manager, InfoSight Corp., Chillicothe, Ohio (dla@infosight.com)
Weigh
Measure Stencil systems provide clear identification of tubes
for both the manufacturer and the end-user. Various WMS floor
geometries are discussed, along with their advantages, disadvantages
and cost ramifications. Optional methods of applying bar codes
to tubes are also discussed.
