how do i make a oven/forge for hardening steel parts etc what setup do you all use?i love pictures
is that a posher name for soft breeze blocksI've used a couple of loose refractory bricks and a propane burner to warm stuff up.
First, whatever your final design, track down scrap night storage heaters . . . then use the bricks inside to line whatever you build. Set them into place with conventional fire cement, they'll take huge amounts of direct heat and retain a stable heat for ages.
A forge is quite different from a furnace. My forge is a shallow metal box about rwo feet square with half a dozen holes in the middle with a pipe attached to an axminster exhaust fan and a shutter to regulate airflow. Get a fire going in the middle, turn on the fan and cover the fire with coke beans and bob's your uncle.
:what parts are u hardening apart from lathe tools . domestic ovens only go to about 240c http://www.technologystudent.com/equip1/heat1.htmTo harden metal i'd just use 4 or 5 soft fire bricks and a propane torch, heat the parts up until they loose they're magnetism or use a tempilstik if the the temperature is critical. To temper the parts depending on the hardness you can use your kitchen oven.
I have comercial blacksmiths hearth & it's lined out with firebricks to A protect the steelwork & B to retain heat with a water cooled tuyere single pipe blower with speed control at right angles from the back & it burns coke, you can also burn coal, the blacksmith at a local museum uses coal.
