新型精密铸造模具加热焙烧隧道窑

New Heating and Baking Tunnel Kiln for Investment Casting Mould

通过对铸造行业铸件模具加热炉与隧道窑的使用性能、结构及特点的分析,结合铸件模具加热的特点,综合考虑铸件模具加热温度、气氛、周期、能耗等工艺要求,针对铸件模具加热设计了新型隧道窑。通过降低窑炉断面高度、采用小功率多烧嘴交错分布、选用新型节能耐火材料、温度采用自动控制等措施,使得设计的新型隧道窑较传统加热炉在降低产品单位能耗、减小模具温差、提高铸件质量、改善操作环境、实现加热工序连续化生产等方面都有很大的改进和提高。

A new tunnel kiln for casting mould was designed through the comparison of the performance,structure,characteristics of the casting mould heating furnace and tunnel kiln in the casting industry,combined with the mould heating characteristics,considering the heating temperature,atmosphere,period,energy consumption and other technical requirements of the casting mould.By reducing the height of the furnace section,using low-power burner staggered distribution,selecting new energy-saving refractory materials,adopting automatic temperature control,the new tunnel kiln has more improvements and advances than traditional heating furnace in reducing the energy consumption of the product unit,decreasing the temperature difference of the mould,increasing the quality of casting,improving the operating environment and realizing the continuous production of the heating process.
