常温自硬呋喃树脂砂是一项制型(芯)新工艺。我厂应用二年多来,成功地解决了生产中一些高难度、高精度的铝合金铸件的铸造难题。 一、铸造模拟试验结果分析 我厂生产的铝合金铸件,不仅形状复杂,且铸造公差有的要求达±0.20mm,表面光洁度为3。为满足设计要求,保证铸造质量,我们首先进行了铸件表面光洁度和泥芯(片状长条形泥芯和塔形泥芯)溃散性的工艺性模拟试验,然后才应用于生产。
Room temperature furan resin sand is a system (core) new technology. I plant more than two years, successfully solved the production of some difficult, high-precision casting of aluminum alloy casting problems. First, the casting simulation test results Analysis of the aluminum alloy castings I plant, not only complex shape, and some of the requirements of casting tolerance up to ± 0.20mm, surface finish of 3. In order to meet the design requirements and ensure the casting quality, we first performed the process simulation test on the surface finish of the castings and the collapsibility of the mud core (lamellar strip core and tower core) before being applied to the production.
