Large pit-type furnaces and deep pit furnaces can be used for high-temperature, medium-temperature, and low-temperature work, and can be used for annealing, quenching, tempering, and other heat treatment purposes for metal materials and mechanical parts such as alloy steel, high-chromium steel, and dade a ɛwɔ manganese a ɛkorɔn.
