在钢的浇注工艺中采用绝热板、保温剂和发热剂等技术,是一项提高钢坯收得率的重要措施。为了不断改善上述材料的质量,从1976年开始试制JR—C2型浇注材料热特性测试仪器,几经改进于1980年初正式定型。经近300炉的测试证明该测试仪结果稳定、可靠,结构紧凑,外形美观,操作方便,安全可靠。 该仪器的基本特点在于产生一个模拟浇注时保温帽中钢水加热的温度场,并根据功率补偿原理,通过炉子电功率记录曲线测出上述材料在该温度场中的热流密度,从而直
In the pouring process of steel using insulation panels, insulation agent and heating agent and other technologies, is an important measure to improve the billet yield. In order to continuously improve the quality of the above materials, JR-C2 pouring material thermal characteristics testing equipment was trial-manufactured from 1976, and several improvements were made in the early 1980s. After nearly 300 furnace tests prove that the tester results are stable, reliable, compact structure, beautiful appearance, easy operation, safe and reliable. The basic characteristic of the instrument is to generate a temperature field for the molten steel heating in the insulation cap during the simulation of pouring. According to the power compensation principle, the heat flux density of the above material in the temperature field is measured by the electric power record curve of the furnace,
