我厂设计制造的RYG-15-7坩埚保温炉,其耐火层炉衬为轻质耐火砖表面贴硅酸铝纤维毡,保温层用硅酸铝纤维棉。具有结构紧凑、升温快(室温升至工作温度的时间为2.5小时)、耗电少(与具有相同炉膛尺寸、相同规格坩埚的36千瓦低压铸造保温炉比较,工作特性基本一致而安装功率减少了21千瓦,即功耗减少58.3％)等优点。该炉从建成到投产,经过近一年的生产考验,性能符合设计要求。现将该炉的主要设计原理及测试结果介绍如下。一、浴炉的设计计算 1.设计技术指标
I plant design and manufacture of RYG-15-7 crucible holding furnace, the refractory lining for light refractory brick surface aluminum silicate fiber mats, aluminum silicate insulation fiber cotton. It has the advantages of compact structure, fast temperature rise (2.5 hours at room temperature to working temperature) and low power consumption (compared with 36 kilowatts low pressure casting holding furnace of the same size crucible with the same furnace size, the operating characteristics are basically the same and the installation power is reduced 21 kW, or 58.3% reduction in power consumption) and other advantages. From the completion of the furnace to put into operation, after nearly a year of production tests, the performance meets the design requirements. Now the main design principles of the furnace and test results are as follows. First, the design of the bath furnace design 1. Design specifications
