Thanks for the replies.
Mike and Ed we did try a second chain from a different supplier and had the same results. Forgot to note this above. However they are both from the same vendor. The stampings are different from chain to chain. In the end we will likely make sure we are getting 316L...
We use 316L stainless chain to drop Zinc Ingots into a galvanizing bath. The bath temperature is 880F. Bath chemistry is 99.5%Zn 0.30%Al 0.005%Fe 0.015%Sb. The chain is submerged beneathe the bath while the ingots melt. The chain is only removed from the bath when more ingots are needed. On...
We clean the surface, wire brush and then degreaser, the problem is the solder doesn't adhere. After soldering the solder can be readily picked off. The solder will only stick if we heat the cast iron over 500F and this causes discoloration, which we want to avoid.
Thank you for the...
We are trying to repair rust pits at water jackets on a cast iron block with Solder and so far are unsuccessful. We've tried rod, silver solder with flux, tried arc welding with low melting point nickel rod none of which worked. Is there a way to solder cast iron at low temperature, keep cast...
Thank you for all the replies. I do make the best of it. I just enjoy working more techinical projects than the 5S stuff. I am already a certified 6-Sigma green belt. I do my main job before my side projects, which is a part of my job desciption as well, and I do it to the best of my...
At my current place of work I was recently, October, part of what they call a lateral move. I got moved from a Process Engineer position on a production line to a postiion titled Process Imrpovement Engineer. In my new role I perform 5S/Lean activities around the plant, harp on area managers...
Thank you for all your replies. I will investigate my options for burners.
Is the option of installing a new burner a viable alternative to buying a new boiler? Meaning we can turn a 20,000lb/hr boiler into a 10,000lb/hr boiler simply by changing burners. Wouldn't the size of the boiler...
I cannot find any info for my steam meter. So I have also looked into water usage by the boilers. We have a totalizer on this meter as well. Assuming 1 pound of liquid water will make 1 pound of steam, I am still burning far to much Natural Gas. Actually I am still at my fuel to steam...
I recently went through some lean training for my company. They put me through an online class from BMG. The cost was $800. I have not received any kind of certification though. But a upper employee here who is a certified lean master told me he would certify me after I completed a Lean...
Some more info:
I will find out if our flow meter is pressure compensated, it is the original flow meter installed in 1997 with the boilers and no one has info on it here.
Also my calculations are not based on a single data point I have used several months of cumulative readings to calculate...
Our boiler is burning very inefficiently. I have modelled our system with SSAT software for Excel and made my own calculations and I get the same results.
We have a 20,000lb/hr fire tube boiler. We burn Natural Gas. On average our the facility only draws 6,000lb/hr steam at 140psi. I have...
Currently we have to take the heat exchangers apart every month. The time interval between taking them apart is not so bad, but the amount of work and time it takes is.
We are also looking into doubling the plates that we have to increase cooling. This is why I am looking more into the...
We have two plate heat exchangers. They have approximately 50 plates each. They are continuing to get an algae buildup inside which must be cleaned by dissasembling the heat exchangers. We have Bromicide in the tanks, but the algae builds up anyway. The algae is a orange brown color.
The...
I attended a small engineering school in the mid-west. I graduated about a year ago with a 3.2 GPA, only had one internship and was never really involved with any campus activities. But after graduation I got offered more money than most of the other graduates in my program. My work...
