furnace hearth meaning in Chinese
炉床 炉缸
炉缸
Examples
- Continuous solidifying furnace hearth car furnace
气体软氮化炉 - Under the load of high basicity occur three circular crevices from top to bottom at the furnace hearth parallel to the furnace shell
在高碱度负荷下，该高炉炉缸部位产生了平行于炉壳的至上而下的三条环裂。 - After thermodynamic calculation on several operation conditions of the furnace , cold - state flow and resistance mensuration , the combustion of the tubular - furnace hearth was changed into swirl and addition of radiate cylinder and oxygen content detection minish 1 . 25 surplus air to less than 1 . 15 , improving the combustion condition and convection and radiate heat transfer efficacy , resuling in reducing the waste - gas temperature 45 , decreasing exhaust gas loss , and saving fuel by 6 %
摘要通过对加热炉几种工况进行热力计算、冷态试验的流场分布及阻力测定和热态试验的炉膛温度场分布及管壁温度等参数的测定，确定将管式加热炉炉膛内直流燃烧改为旋流场燃烧和增加辐射筒，增设烟气含氧量分析，可以将燃烧的过剩空气系数从1 . 35减小到1 . 15以下，极好地改善炉膛内的燃烧状况和对流辐射传热效果，从而降低排烟温度45 ，减少加热炉排烟损失，节约了煤气量6 %以上。 - Abstract : based on the analysis of influence of tubular rib construction on heat transfer area on steel blank and heat transfer space in furnace , a t - shape support system for tubular rib is presented , by which the construction of wholly overhead furnace hearth can be realized for large and medium scale continuous reheating furnaces , making furnace gases to come into full contact with steel blank , raising space utilization ratio of furnace chamber and improving heat exchange
文摘:分析了炉筋管结构形式对传热空间、坯料受热面积的影响；提出采用t形支撑技术优化炉筋管，可实现大、中型连续加热炉的全架空炉底，使炉气与坯料表面充分接触，提高炉膛空间利用率，可较大幅度提高炉膛热交换。
