结合对老式的SL-71-99型输送带淬火加热电炉的大修,我们对该电炉采用复合炉衬,改变了加热体的部置方式和炉膛结构,制造了节能输送带淬火加热电炉。经过空载运动和生产实践表明,与老式电炉相比,该电炉具有节电、高效和维修方便等特点。一、节能方案的选择通常,热处理电炉的节能改造,对周期式作业炉主要是降低蓄热量;对连续式作业炉,主要是减少散热损失。SL-71-99型输送带炉是连续式作业炉。能不能既减少散热又降低蓄热量达到节能的目的呢?回答是肯定的 SL-71-99型电炉装料口经常处于开启状态。由于热幅射及空气对流的作用,炉门热
Combined with the overhaul of the old SL-71-99 conveyor belt quenching electric furnace, we adopted the composite lining to the electric furnace, changed the arrangement of the heating body and the furnace structure, and manufactured the energy-saving conveyor quenching electric furnace. After no-load motion and production practice shows that, compared with the old electric furnace, the electric furnace with energy-saving, efficient and easy maintenance and so on. First, the choice of energy-saving options In general, energy-saving heat treatment furnace, the cycle of operating furnace is mainly to reduce heat storage; for continuous operation furnace, mainly to reduce heat loss. SL-71-99 conveyor belt furnace is a continuous operation furnace. Can not both reduce heat and reduce heat storage to achieve the purpose of saving it? The answer is yes SL-71-99 type electric furnace charging port is often open. Due to the effects of thermal radiation and air convection, the furnace door is hot
