Steel Mill Equipment Installation

Entry Trough Custom Equipment

At the end of October 2018, GMB Heavy Industries successfully completed a five-day outage at a bar mill in the United States. The mill was designed with a pneumatically activated separating ledge in the entry trough. This type of drive was proving itself unreliable, as it was adversely affected by both the ambient temperature, and the temperature of the equipment. Consequently, it was impossible to achieve a consistent/repeatable cycle time of less than 0.9 seconds throughout the year for all products. The solution was to replace the pneumatically activated system with an electro-mechanical drive. This system produced a faster cycle time, and also increased reliability. All the equipment for the upgrade was supplied and installed by GMB Heavy industries.

Fixed and Moving Rakes Supply

At the end of October, GMB Heavy Industries successfully completed a ten-day outage at a medium section mill in the United States. GMB supplied fixed and moving rakes, as customer had issues with achieving product straightness and proper carry over. Carry over was also a particular problem, due to the particularly wide bed, where each rake is comprised of three sections. The section of each rake, closest to the entry trough was replaced. These sections were determined to be those in most need of replacement. As the customer had a limited budget for the bed upgrade, GMB interacted closely with management to determine which improvements would provide the best return on investment.
Also, as part of this cooling bed upgrade, GMB rebuilt the Entry Trough Wiper Arm, and also replaced the Wiper Arm Button Rolls.
