Hardening or softening metal (e.g. to make less easily marred tools, knives) is how I got there, not sure of non-metal-working uses.
I suppose though if you can get it to hold cooler temps too, then it's just an oven, could use for reflowing solder, testing performance of something at higher temperatures, warming bagels..
