炉篦条消失模铸造工艺优化

炉篦条是冶金设备烧结机上的一个重要零件,对铸件技术要求高,工作面不允许有铸造缺陷,采用消失模铸造生产炉篦条是一种先进、高效的生产工艺。针对原消失模铸造工艺经常出现的夹渣、夹砂等问题以及铸件报废的原因,在对原工艺认真分析的基础上对炉篦条铸件铸造工艺进行了优化:改变铸件浇冒口的设计,将原来的2个冒口向铸件长度方向的中间靠近;将铸件在浇注位置方向上的工作面朝下,以保证工作面的铸造质量;从管理、工艺实施和监督检查方面进行严格控制,消除气孔,保证涂料烘干,防止涂料返潮。通过优化铸造工艺,有效提高了生产效率,降低了生产成本。批量生产也证明了优化工艺性能稳定,产品质量可靠。

Process optimization of fire bars with EPC

The fire bar is one of the important parts of metallurgical equipment, with high technical requirements of casting, whose working face does not allow casting defects. The EPC production method of fire bars is an advanced and efficient production technology. The fire bars produced by former technology often have slag, sand and other defects, so based on analysis of the original process, the optimized design of casting riser is put forward. The two risers in the original casting are designed to be nearer along the length direction; The working face of casting on pouring position direction is adjusted to be down, assuring the quality; Strict control from the aspects of management, process supervision and inspection is needed to eliminate air hole, ensure drying of the paint coating, and prevent damping. By optimizing casting process, the efficiency of casting production is effectively improved, and the production cost is reduced. Mass production also proves that the optimization of process performance is stable, and the product quality is reliable.
