Trolley furnace is a national standard energy-saving periodic operation furnace with super energy-saving structure. It adopts composite fiber insulation, ultra light weight and high-strength micro bead vacuum ball energy-saving brick. It is exclusive to produce anti falling wire upward inclined 20 ° wire laying brick, furnace mouth anti workpiece impact brick, automatic sealing trolley and furnace door, integrated rail connection, and can be used on the horizontal ground without foundation installation. It is mainly used for quenching, annealing and aging of high chromium and high manganese steel castings, gray iron castings, nodular iron castings, rolls, steel balls, crusher hammers, wear-resistant lining plates and heat treatment of various mechanical parts.
The shell of this series of electric furnace is welded by steel plate and section steel. The trolley is welded by section steel and steel plate. The trolley reduces heat radiation and convection loss through soft contact with furnace lining and sand sealing mechanism, so as to effectively ensure the tightness of furnace body. The furnace lining adopts full fiber structure, which can save about 30% energy compared with brick furnace. Long fiber blanket is used as raw material, and special equipment is used to make 300 × 300 × 300 specification. A certain amount of compression is left in the process of processing. After the completion of masonry, each ceramic fiber block expands in different directions, so that the modules are extruded into a seamless whole, which achieves good heat storage effect The product construction is convenient and fast, and can be directly fixed on the stainless steel anchor round nail of the furnace shell steel plate. Compared with other products, it has the advantages of low heat conduction, low heat capacity, excellent corrosion performance, excellent thermal stability, thermal shock resistance and thermal insulation, and the anchor is set on the cold side of the furnace body to improve the high temperature resistance of the fiber.
