Having worked with furnaces and vehicles springs for many years the basics of heat treatment are quite simple, what is is difficult is getting even temperatures along the whole item.

A forge works well with a short blade, knife of spear head, but a bow would need a furnace chamber to get an even temperature otherwise you could not get an even temper, one end would bend/flex more than the other.

EN45 silicon manganese spring steel hardens at 850C, oil quench then temper at 650C and allow to cool, good luck.
