The Rose Corporation was fortunate to host a recent Lean Thinking Network meeting. To my recollection, this was the best-attended meeting ever, and with 25 team members, representing nine separate companies it provided ample feedback to The Rose regarding our successes and failures with Lean implementation. Moreover, all but two guests stayed for lunch and the afternoon training session titled “Reinvigorating a Stale Process; Making Continuous Improvement Simpler While Making Work Easier”. The host company has the option to request the training topic so The Rose asked Dwight Bowen to focus and train on what things a company can do to keep its continuous improvement (CI) efforts effective, meaningful and on target.
Despite the declining preference for endothermic dissociated ammonia generators, The Rose Corporation has a fairly large number of customers still operating our Drever Ammonia Dissociators, and for a variety of reasons. The primary reasons for staying with dissociated ammonia for production can be broken out into two, externally driven factors which are, compliance with governing agency’s recertification processes and demanding zoning codes.
The Rose Corporation provides technical field support to its Drever industrial furnace customers through a team of highly qualified, skilled technicians and engineers. One Drever customer recently used our field technical service to support their own maintenance personnel in the removal and reinstallation of the catalyst chambers in one of their three Drever 3000 SCFH Ammonia Dissociators. “Our customer’s maintenance personnel are incredibly talented and knowledgeable individuals, and easily capable of handling this project on their own” says Rose Corporation’s Tom McDevitt. “We were there to provide technical support in the event something outside their experience or comfort zone came up that had the potential to delay returning the dissociator back over to their production teams.”

We recently learned that by the time some of the fabricated stainless steel valves we built arrived overseas, they had signs of rust. Now, we all know that stainless steel doesn’t rust; however stainless steel “contaminated” with carbon steel or free iron can form surface rust.
A recent project we fabricated for a customer of Mark Metals for the Atlanta Braves new stadium really showcased our welding, material handling, and blast/paint capabilities.
The effects of material contamination when dealing with nickel-bearing alloys used in high-temperature applications such as process furnaces is well documented. Despite this awareness, and the subsequent impact on cost management and production schedules, there remains a constant stream of incidents where root-cause analysis identifies materials contamination as the problem. Furnace rolls, mesh belts, muffles, refractory anchors, and more are some of the nickel-bearing items failing prematurely due to contamination.
At the Rose Corporation we are always looking for ways to improve production and increase efficiency. Just like with our recent floor project, sometimes this means investing in the company. Two new jib cranes have been added to service our new 30’ x 60’ floor area. Both cranes are 22’ long with a 2 ton capacity. They will have access to 60 % of the total floor area. Fitters and welders will utilize the new jib cranes to move smaller job components around the floor area and also to hang wire feeders to make welding easier on larger weldments. This will also help to free up the larger shop cranes in that bay to help keep production flowing in other areas. This upgrade will allow the workers to do their jobs much more efficiently which will ultimately increase production levels in the shop.
The Rose Corporation helped a specialty aerospace metals manufacturer recover from a meltdown disaster in one of their vacuum induction melt furnaces. The meltdown occurred on December 18th, management met with customer engineers on the 19th and TRC started demolition on the 20th. Working every day around the clock, except Christmas and New Years, TRC completed the rebuild four days ahead of schedule and by doing so made a strong impression on the customer that TRC and The Rose Corporation can get things done.
An industrial furnace customer operating a 1000 SCFH Ammonia Dissociator encountered unexplained “soot” buildup on their furnace belt, product, and flowmeter. Prior to this incident the customer’s Drever Ammonia Dissociator had operated for many years trouble-free; however root-cause analysis revealed the following conditions that lead to this condition: propane was accidentally pumped into the ammonia storage tank servicing the ammonia dissociator.
Rose Corporation was awarded a job to build a Research Altitude Chamber for a large customer of ours that is now in the testing phase. The Chamber was commissioned by the Wright Patterson Air Force Base in Dayton Ohio.
