I poured my opening with reinforced cement. No angle iron required. Square or arched, it will support your oven.

1/4 inch will work. Thats what I used but my span was around 3 feet. 3/8 seems pretty thick...

Couple things. First, you can usually find the angle iron you need at a building supply store. Its used over windows for bricks.

Second, you don't need angle iron at all. I put some rebar inside the blocks, supported the blocks with other blocks, poured concrete into the dry-stack, and that was that.

In fact, if I ever do this again, I am going to skip the row of blocks over the lower door because it makes the door top too low. The slab for the oven will span about 60 to 70 inches all by itself - you don't need a center post or anything, so its perfectly capable of spanning 30" or whatever over what happens to be the lower door. So, you can make your dry stack ways and fill them up (nothing over the lower door). Prepare your form for the oven slab, adding a few extra rebar above the door opening. Support the wood above the door opening really well with blocks or something and pour the slab.

It is true you need angle iron to support blocks because blocks (or concrete) don't do well under tension. However, rebar is a fix because its very strong under tension. They make concrete 'beams' (just concrete with rebar) spanning huge distances all the time, and the slab above the opening is just a small concrete beam.
