Re: castable refractory

Hi Steve
I am just at the last stages of completing a cast oven. I used Darley Densecrete 145 for casting the dome and it worked a treat. I also used their refractory tiles for the base which are 305 x 305. This determined the size of the oven floor at 915mm.
Happy to post more pics of the construction if you need.
Cheers
Willy

Re: castable refractory

The nice thing about using industrial materials is that the manufacturers have process engineers on staff who's job is to answer questions just like this. These guy's jobs are pretty routine, and they often enjoy getting a question out of the ordinary. You should call Darley Refractories and say you have a technical question about a product. Explain the project, the thickness, the temperatures, the exposure to direct flame, and ask for a recommendation. Then come back and tell us what you learned.

Hi All,
As with everybody else here, I seem to have spent ages reading about brocks and designs. I am utterly in love with the dmun's geodesic dome and edschmidt
castable triangles.

After much model, lots of paper cubes lying around, I am thinking of heading down the castable route. But, what castable should I use.I have searched for castable refractory and am presented with a variety of types. I am assuming I won't be wanting insulating stuff but which ones do I go for?

darleyrefractories dot com au (I can't post links) has 4 which are insulating and 3 high temp ones. Any advice anyone?

I plan to build a 90cm (36 inch) ,or there abouts, dome in the next 6 months.

Thanks
Steve
