在我国,几年来广泛应用远红外加热方法.我厂在1978年采用板形远红外炉烘烤铸件砂芯.由于机械工业的飞跃发展,能源愈来愈紧张,铸件质量要求日益增高,因此,在1980年,我改进设计了一个管形远红外砂芯烘炉.经过一年来的使用,效果较好,能节电25%以上,合脂砂芯烘干质量也大有提高,由于芯子不干而造成铸件气孔的现象已消除. In our country, the far-infrared heating method is widely used in the past few years.Our factory baked the sand core of the cast-shaped far-infrared furnace in 1978. Due to the rapid development of the machinery industry, the energy is more and more tense and the quality requirements of casting are increasing day by day. In 1980, I improved the design of a tubular far-infrared sand core oven.After a year of use, the effect is better, can save more than 25%, combined sand core drying quality is also greatly improved, because the core Do not do and cause the phenomenon of casting porosity has been eliminated.
