解决合金冷硬铸铁辊筒铸造生产过程中产生的气孔、夹杂、裂纹、冷硬层超深或者无冷硬层等铸造缺陷而导致的废品率居高不下的技术问题,同时为了降低废品率,提高生产效率和品质,通过采用自硬呋喃树脂砂生产线生产合金辊筒。经过生产实践,该工艺不仅简化了操作工序,提高了生产效率;还缩短了生产周期,运用合理的浇注工艺和浇注方式还提高了产品的品质。
The invention solves the technical problems of high reject rate caused by casting defects such as pores, inclusions, cracks, ultra-deep cooling layers or non-cooling layers generated during the production of alloy chilled cast iron rollers, and at the same time, in order to reduce the rejection rate, Improve production efficiency and quality by producing alloy rolls using a self-hardening furan resin sand production line. After production practice, the process not only simplifies the operation of the process and improve production efficiency; also shorten the production cycle, the use of a reasonable casting process and casting methods also improve the quality of the product.
