OTHER NOTABLE PROJECTS
Caster Billet Pusher/Weigher
When it became time to add weighing capability to the existing billet pusher hydraulic system, the decision was made to greatly expand the hpu room and build a new expanded power unit as well. AHS was tasked with designing the new power unit and associated valving. In addition, we were asked to draw floor plans to ensure that all of the equipment and piping would fit in the new building, with room to spare. The project came off without a hitch, and has been up and running ever since.
The HPU was originally located in a dark basement where maintenance often went undone. Advanced Hydraulic Solutions, Inc. was commisioned to install a fully closed-loop controlled, true force-determining in-feed system for blind loading of material at any time of the day or night. We brought the HPU out of the basement to a more accessible area. We were able to refurbish the stainless steel tank and electric motors to save the customer money on the installation. Some work had to be done to make it fit in its new home. Further, we significantly upgraded the filtration so we could install servo valves out in the plant. This has consistently been one of the most reliable systems we have ever installed.
Electric Arc Furnace
One of our steel mill clients asked us to redesign their electric arc furnace hydraulic system, and to manage the project. The challenge was to get all materials and components on-site before work was scheduled to be started, and then to manage the many contractors necessary to make it all happen. It was completed on-time and under-budget, the first charge was fired on New Year's Eve.
Originally the system was designed with proportional valves and European valve patterns that made sourcing parts difficult and expensive. While documenting the system, Advanced Hydraulic Solutions, Inc. discovered that only two pressures were needed to maintain full system functionality. We went to work changing the system to a dual pressure circuit, with standard valve patterns that are in stock locally. In addition, we designed and built custom ductile iron manifolds that would accept standard replacement parts. This streamlined maintenance and made inventory management a breeze for the customer.
