Click to expand Hello Liger! Your customer should be one of best sources of information. It is in both of your best interests to locate the specification s for the products. If you make several products for one customer, there might be more than one specification. If not, you may have to consider scheduling your work for the various furnaces. The capability of the equipment is another matter. So below that temperature, air is generally heated and recirculated. The amount of BTU available will dictate how quickly a particular oven with a particular load can come up to temperature.
However, the of air changes, louvers, exhaust, air balancing, etc. The better the uniformity, the more air changes and consequently a higher cost. I go on about this because it is an important point at least to me. If you have a tight TUS requirement and your equipment is not going to be able to produce, you will need to make modifications to your existing equipment, get different equipment, or do something else.
I had further discussions with my maintenance man yesterday evening, and developed another question. The TUS we have performed tracks 3 thermocouples that are organized in a plane on the mesh belt, and one channel tracking our temperature controller.
The temperature controller thermocouple is located outside the inner tunnel that the belt and parts pass through. This controlling thermocouple is approximately a foot above the belt-mounted thermocouples, and the belt is moving at a speed of approximately 15 IPM, so there is no staionary soak time.
As such, the belt mounted thermocouples read approximately degrees cooler than the controller. Is there some calculated offset permitted in determining acceptance of these test results? There must be some acceptable offset, as due to the location of the thermocouples and the operaiton of the machine, the belt thermocouples will always read lower than the controller thermocouple. Once that "hot air" is blown onto the cold conveyor belt with cold parts, the air is going to be colder.
It may be necessary to move the controller thermocouple further into the realistic work zone. What I would do is 1 find out what your requirements are.

Heat treatment is an essential process for many critical parts of an airplane, so it is understandable that there are tight regulations and audit processes set. While the results and success of some other industrial processes can be relatively easily measured after the process, this is not the case in a heat treatment process. Therefore, very tight control and documentation of the heat treatment process is essential to assure the quality of the end products. Followed by revisions: revision A in , B also in , C in and D in
