Thanks guys. You have been a tremendous help. V

One last thing that may make a difference. They tend to experience some thermal shock as they pull these out every so often to swap them around (ie. putting in a thermocouple or gas injector). Thanks

Thanks. The end use is in a carbon bake furnace flue port cover. They have used cast iron in the past, but we are not sure of the alloy or grade.

we are searching for a cast iron grade (alloy if so) that has a maximum service temp. of 1500 F or greater. searched Matweb & could only find 1350F. Does anyone know of a grade that meets this crteria? Thanks.

Anyone have any tips on opening a program (.exe) when you create a new part? The program is some software that I wrote outside of solidworks (not a macro) that I need to open when I create a new part. Thanks!

Normally I do the same, but this was a very specisifc weld that had to be air tight & I wanted make sure that my guys saw it. I used a pofile revolve to mimic a weld. Thanks to all. V

Thanks! I'll do that. V

I have a 1/2" sch 40 pipe going through a pipe cap with a 7/8" dia hole. This leaves a bit of space between the two. I need to add a weld bead in the assembly, but cannot figure it out. I am new to SolidWorks. Anyone have any sug. on this or a site that can show me how? Thanks

Well....they do not know. No one apparently has had this problem, but I can re-create it on 3 different computers. I issued my PO today for the full version. Thanks for the help. V

I have only had this installed for about 1 week & I think it is a license issue also since it is doing it on my home computer. I will post the results after I talk to my reseller. Thanks

I just started getting this message. I create a new drawing, add the model, save, close & then repoen. I get the error & it closes the drawing. Here is the error: "Invalid Object Index, file is corrupt" Using SWX PE 2005. Thanks

I am not sure what you mean by one dimensional. All of our heat flows that we do are basically taking a wall of infinte height & depth & calculating the cold face temp by knowing the inside temp, k-factor, insulation thickness & if it is a sidewall, hearth, or cylinder. Would that be...

Larry- ASTM C680....well worth buying. Thanks & let me know your thoughts on the spread sheet. IRstuff- Let me know your thoughts also. Thanks fellas!

I am currently working with our material supplier on this & they have given me a list of coefficients to use for the material & I am using a Heat Flow program from another supplier. I can email this program (excel document) if anyone would like to take a look at what I am trying to do. Also I...

Thanks to both of you. I will let you know how things turn out.

To start, I am not an engineer. I am a programmer trying to write a steady state heat flow program for refractory linings for my family business. I keep running into problems. With the heat flow programs I have seen, not one will ask to guess the coldface temps & the mean temps. Essentially...
