Meeting our Clients' Needs

Adding Eccentricity Control

One client installed a Quest feedforward gage control system on an aluminum rolling mill. The system reduced incoming thickness variations, but it could not control thickness variations caused by the mill. Quest added the roll eccentricity control module to the QCS 2000 components already installed. The result was a significant improvement in product quality.

Adding Propulsion Control

Another client installed new technology for gage and shape control. Even with the latest technology, there were productivity problems getting the strip through the mill. Motor control hardware, installed almost thirty years earlier, was showing its age. Quest provided the client with a turn-key propulsion control system that controlled motors and replaced other aging control systems. In tests after commissioning, the new system showed significant speed and productivity increases.

Reducing Scrap Wire

Quest has also applied its engineering know-how to achieve a dramatic reduction in the unusable scrap wire produced by a copper wire drawing machine. With 54 bobbins per winding and 500 feet of variance in wire length on each bobbin, the machine was producing up to 27,000 feet of scrap wire per winding. After Quest redesigned the wire winding system, the scrap was reduced to no more than 1400 feet per winding, an enormous cost savings for the client.

Controlling Furnace Temperature

Another client called on Quest to provide new temperature control software for an annealing furnace. Quest's responsibility was to write the software that controlled the furnace temperature, temperature measurement, burner sequencing, pulsing, etc. This software needed to be coordinated and dovetailed with two other vendor's software assignments. Quest wrote and installed software that is reliable, understandable, maintainable, and well documented.
