Characterization of the Strength of a Natural Sand and Artificial Sand Core Manufactured with Inorganic Binder
물유리계 바인더로 제조한 천연주물사와 인공주물사 중자의 강도 특성
Min A Bae, Pan Seong Kim, Kyeong Ho Kim, Man Sig Lee, Jae Ho Baek
배민아, 김판성, 김경호, 이만식, 백재호
Korean J. Met. Mater. 2021;59(4):273-280.   Published online 2021 Mar 24
DOI: https://doi.org/10.3365/KJMM.2021.59.4.273

Abstract
Natural sand and organic binders are commonly used in casting processes, but these ingredients produce environmental problems with dust and harmful TVOC(Total Volatile Organic Carbon) gases. Research on the introduction of artificial sand and inorganic binders to solve these environmental problems is being actively conducted mainly in the casting industry...... More

      
The Effect of the Surface Energy of Water Glass on the Fluidity of Sand
Min A Bae, Man Sig Lee, Jae Ho Baek
Korean J. Met. Mater. 2020;58(5):319-325.   Published online 2020 Apr 20
DOI: https://doi.org/10.3365/KJMM.2020.58.5.319

Abstract
In recent years, the metal casting industry has sought to meet ever more stringent environmental standards. Inorganic binders based on silicate chemistry have many advantages with respect to environmental issues, but often suffer from reduced strength, burn-on and poor water-resistance. In particular, when sand is mixed with a water glass..... More

Effect of Additives on the Sand Burning of Inorganic Binder in Al-Si7Mg Alloy Casting
물유리계 바인더의 첨가제가 Al-Si7Mg 합금 주조 시 소착에 미치는 영향
Min A Bae, Myung Hwan Kim, Jeong-Wook Park, Man Sig Lee
배민아, 김명환, 박정욱, 이만식
Korean J. Met. Mater. 2018;56(4):327-333.   Published online 2018 Apr 5
DOI: https://doi.org/10.3365/KJMM.2018.56.4.327

Abstract
Traditional organic binders used by the foundry industry produce problems such as generation of volatile organic compounds(VOCs), smoke and etc. A water glass binder system has been developed to improve the casting strength and to solve the environmental problems. However the water glass binder has a serious problem of sand..... More
