A brief introduction to the trolley furnace by the manufacturerPublished by：2022/6/5 Categories:News Viewed by: 7212 times The trolley furnace is a national standard JN type periodic operation furnace with a super JN structure. It uses composite fiber insulation, ultra lightweight and high-strength microbead vacuum ball JN bricks, and produces anti drop wire inclined 20 ° wire support bricks, furnace mouth anti workpiece collision bricks, actively seals the trolley and furnace door, integrates rails, does not require basic equipment, and can be used on a horizontal ground. S is used for high chromium, high manganese steel castings, gray cast iron parts, ductile iron parts, rolling mills, steel balls, crusher hammers, wear-resistant lining plates, quenching, annealing, aging, and heat treatment of various mechanical parts. The shell of the general trolley furnace is welded from steel plates and section steel. The furnace lining material of the electric furnace is made of ultra lightweight 0.6g/cm Э JN refractory insulation bricks, and the interlayer is insulated with aluminum silicate fiber felt. The space between the furnace shell and the silicon aluminum brazing interlayer of the furnace lining is filled with expanded stone powder insulation. The furnace mouth is made of heavy anti-collision bricks and the trolley surface layer is made of heavy high aluminum anti pressure bricks.
A maze type refractory material is used to build the exterior between the electric furnace body and the trolley. The heating elements of this electric furnace are all spiral shaped heating elements, placed on the side of the furnace and the trolley masonry. The heating element material is internationally recognized 0Cr25AL5, and the high operating temperature of element Z is 1200 ℃.
