摘要
研究了一种铸造金属颗粒用定量器滴嘴的结构及其制造工艺。结果表明,由烧结陶瓷加工而成的滴嘴本体及与滴嘴本体配合的塞子两部分构成的组合式定量器滴嘴,强度高,韧性、耐磨性和耐蚀性好,使用寿命长,更换时不断裂,可提高铸造金属颗粒生产线的作业率,降低金属颗粒加工成本。金属液流经定量器滴嘴后,能够实现平稳、断续流动,加工的金属颗粒尺寸均匀、稳定性好。
A new kind of batcher drip nozzle used for casting metal grains and its manufacturing process have researched.The results showed that the composite batcher drip nozzle consisting of ceramics drip nozzle and plug had high strength,excellent toughness,abrasion resistance and corrosion resistance, and long service life.It was not easy to fracture while replacing.The new batcher drip nozzle could increase the productivity of production line and decrease the production cost of metal grains when it was used to cast metal grains.After the metal liquid flowed alone the batcher drip nozzle,the fluxion was calm and chopping.The dimension of metal grains is even and the stability of production is verv good.
