However, this method has not been used in the detecting of molding sand moisture in the Foundry Industry.
但近红外检测技术目前尚未应用于铸造车间型砂水分的检测。Molten metal is poured into a mold cavity formed out of sand.
将熔化的金属倒入由型砂做成的铸模的型腔中。Elastic modulus is one of the important physical parameters of molding sand, and it is tightly connected with properties of molding sand.
弹性模量是一个与型砂性能密切相关的重要物理参数。The gas evolution test method has the advantage that the effective coal dust content in green sand can be determined rapidly and accurately.
发气量试验方法的优点是能够迅速和准确地确定型砂中有效煤粉的具体含量。The system can test active clay content and moisture of green sand fast and control its composition directly.
该系统能快速测定型砂的有效粘土含量和含水量，实现型砂质量的直接控制。best combination of low speed scraper and medium speed rotor , large mulling sand , even - mulling ability , good integrated performance.
低速刮板与中速转子最佳配合混砂量大混匀能力强，型砂综合性能好。The drag is first filled partially with sand, and the core print, the cores, and the gating system are placed near the parting line.
先将下型箱装上部分型砂，安放好型芯座、型芯，浇通系统应放置在分型线附近。A grey relation analysis mould used to evaluate the quality of molding sand was proposed.
提出了铸造型砂性能评价的灰色关联分析模型。A new type of intelligent instrument for the detection of moulding sand moisture is presented in this paper. Its nucleus is microcontroller.
