原砂 meaning in Chinese
raw sand
roughing sand
Examples
- Foundry sands and sand mixtures for casting - method of testing
铸造用原砂及混合料试验方法 - Raw untreated sand
未处理原砂 - For foundry sand from a famous domestic area , the curve of thermal expansivity with the temperature was described
本文最后给出了利用本装置测得的国内某著名铸造用原砂的热膨胀温度曲线。 - So that the students can choose different labs and parameters in order to do some simple experiments as character of nature sand , mould assemble and numerical simulation of solidifying process
学生可以选择不同的实验，对实验进行浏览，选择实验过程参数，并能完成原砂性能、模具拆装，凝固过程数值模拟等简单实验。 - A thermal expansivity test device consisting of hating unit , attemperating unit , displacement transducer , recorder and so on , was developed to determine the thermal expansivity of new sand , clay - beaded sand , sodium silicate sand , resin bonded sand with the temperature or isothermally
摘要铸造用砂热膨胀性测试装置，由加热装置、温控装置、移位传感器、记录仪等组成，可实现铸造用原砂（亦可用于粘土型砂、水玻璃型砂、树脂型砂等）的随温和等温热膨胀性测试。
