气流冲击造型机是一种实砂效果好、速度快、适用性强、无噪音和结构简单的造型机,因此,目前引起国内外铸造界的重视。用它来进行铸铁生产已有了成功的经验,但用于铸钢生产仍处在一个摸索阶段。我厂从西德BMD公司引进的规格为1700×1400×850/850气流冲击造型机将于今年五月安装完,为了保证这台先进的造型机能顺利地投入铸钢生产,我们与江西工业大学铸造教研室在该校进行了铸钢水玻璃砂和单一砂在气冲造型机上的造型试验。通过试验,掌握了这两种砂在冲实下紧实度变化的一般规律和常见的一些工艺因素的影响,基本上达到了工艺验证的目的。
Air impact molding machine is a real sand effect, speed, applicability, noise-free and simple structure of the molding machine, therefore, the current casting industry at home and abroad caused the attention. It has had a successful experience with cast iron production but it is still in a groping phase for the production of cast steel. Our plant imported from Germany BMD company specifications for the 1700 × 1400 × 850/850 air impact molding machine will be installed in May this year, in order to ensure that this advanced molding machine can successfully cast steel production, we and Jiangxi University of Technology Foundry Teaching and Research Office at the school conducted a cast steel sodium silicate sand and a single sand in the air impact molding machine modeling test. Through experiments, we can grasp the general rules of the compaction of these two kinds of sand and the influence of some common technological factors, and basically achieve the purpose of process verification.
