Heat Treat - Metallurgy of Steel for Bladesmiths & Others who Heat Treat and Forge Steel Part 2

Heat Treat - Part 2 Heat treating of metals is essential to the production of durable products. These products are heated in a furnace to the proper temperature and then cooled by some sort of quench medium: air, salt, quench fluid, or oil. The use of oil quenches is wide-spread and the quench facilities generally fall into two categories - open and enclosed. In many Open Quench Tank operations, the parts, as they exit the furnace on the furnace conveyor, drop into an oil bath through a chute. A conveyor, submerged in the oil, carries the parts through the oil for the prescribed time A drip pan under the exit conveyor catches the quench oil draining back into the quench tank. A fume collection hood and exhaust duct create a secondary area for concern. Heat Treat Source: https://www.spreaker.com/user/15730398/chapter-one
