我厂为解决大型工件的热处理,设计了一台用硅酸铝耐火纤维作绝热保温材料的大型台车电阻炉,用于碳钢、合金钢工件的淬火、回火、正火、退火、调质。要求最高工作温度1000℃,升温速度60℃/h,最大装炉工件φ4000×450mm,单重6000kg;装炉量为25000kg;炉膛有效容积为4500×5000×1200mm。台车位置的上部、侧墙、后墙、炉顶均选取比重(γ)为250kg/m~3,平均导热系数(λ)为0.105kCal/m·h·℃,厚度为5×20mm的硅酸铝耐火纤维。台车位置的侧部,
I plant to address the large-scale heat treatment of the workpiece, the design of a silicate refractory fiber insulation materials for large thermal insulation resistance furnace, for carbon steel, alloy steel parts quenching, tempering, normalizing, annealing quality. Requirements maximum working temperature 1000 ℃, heating rate 60 ℃ / h, the largest furnace work piece φ4000 × 450mm, single weight 6000kg; loading capacity of 25000kg; furnace effective volume of 4500 × 5000 × 1200mm. The top, side wall, rear wall and top of the trolley are selected to have a specific gravity (γ) of 250 kg / m 3, an average thermal conductivity (λ) of 0.105 kCal / m · h · ° C and a thickness of 5 × 20 mm Alumina fire-resistant fiber. Side of trolley location,
