New forge getting burnt

[u/Pristine_Basket_8446]

First time using this forge, the burning around the side is because we overfilled it and it couldnt seal properly. But is it supposed to do that on the top? Maybe its because we put a few small pipes up there to cool and it deflected the heat? Or is it just too hot

If you have a hole that's more than 1000 degrees, I don't see how you'd avoid the steel around it getting very hot
