Heat Treatment Furnace Accurate Control Of Furnace Temperature

Heat treatment furnace is composed of furnace wall, roof and bottom three parts. Generally with refractory bricks, refractory castables and refractory fiber cotton and other materials as lining, due to furnace type, refractory varieties and heat treatment process conditions of its different service life is not the same.

The use of insulated refractory bricks and refractory masonry lining for a variety of heat treatment furnace. The thickness of the furnace wall is generally about 460 mm. Insulation layer thickness of 70 ~ 230mm with a bulk density of 0.8g / cm3 diatomaceous earth refractory bricks, clay or high-alumina insulation brick, floating beads or calcium silicate insulation board masonry. Working layer thickness 230 ~ 348mm.

Chain furnace and muffle furnace and other high-temperature annealing furnace working layer with clay refractory brick masonry continuous horizontal furnace, tower furnace and hood furnace furnace working layer available bulk density of 0.8 ~ 1.0g / cm3 clay Or high-aluminum insulation brick and floating beads brick masonry roll furnace on the side of the masonry roll masonry masonry to facilitate the replacement of the furnace roll, tower furnace and pit furnace furnace wall to prevent the whole Pour out every 2m high parts should be installed metal joists or tiles and connected with the furnace shell. The holes in the furnace wall are surrounded by clay refractory masonry. The use of non-hood or muffle of the bright treatment of vertical furnace and tower furnace and other equipment when dealing with stainless steel and other senior metal materials need to pass high purity dry hydrogen or nitrogen and hydrogen and other protective gases so the furnace must be high purity Refractory material that is the lower part of the furnace wall and some special-shaped plate and the tube should be sintered or fused corundum material to build the remaining furnace wall with alumina hollow ball insulation brick masonry mud must also be used with the masonry. Such materials in the heating process does not precipitate any harmful gases and can resist the destruction of hydrogen so the furnace application life is longer.

The roof is divided into hanging flat top, fixed or removable vault and so on. The top of the furnace is a moving lid. The thickness of the work and insulation layers of the furnace tops are 230 mm and 70 to 230 mm, respectively, and the refractory material used is basically the same as that of the furnace wall.

Heat treatment furnace bottom in addition to the chain furnace and some muffle furnace are load-bearing. The working layer and the thickness of the insulation layer are generally 230mm and 70 ~ 230mm. The former with clay refractory masonry the latter with clay or high-alumina insulation brick, floating beads or diatomite brick masonry use. Heat treatment furnace brick furnace body under proper operating conditions for the service life of 3 years to reach more than 4 years. During this period vulnerable parts of the lining to go through several minor repairs.
