Speaking of Muffle, the first thing we need to understand what is muffle, which is the liner of an industrial steel coil annealing furnace. The liner is made of high temperature resistant 310S stainless steel, made in China and also made in Switzerland.

Whether an industrial steel coil annealing furnace has muffle or not has a certain effect on the effect of production line. If it is operated by a technician with poor skills, the effect will be relatively obvious. Industrial steel coil annealing furnace with muffle liner has better heat preservation effect than annealing furnace without liner, because it is sealed, and the space is small, so the heat is concentrated. And the industrial steel coil annealing furnace without muffle liner, due to the larger internal space, the gas consumption will be larger, and may also contain more impurities, the production and processing effect will be slightly less, but for skilled technicians, the processing speed and output is also more than that with muffle.
