The Study on the Manufacturing Cold Cured Briquette Using Curing Reaction of Sodium Silicate
규산 소다의 경화 반응을 이용한 상온 경화 괴성광 제조에 대한 연구
Kang-Min Kim, Jeong-Whan Han
김강민, 한정환
Korean J. Met. Mater. 2020;58(6):369-374.   Published online 2020 May 20
DOI: https://doi.org/10.3365/KJMM.2020.58.6.369

New technologies need to be developed in the ironmaking process to reduce carbon dioxide emissions. To achieve this, in recent years steelmakers have been working to reduce coke usage by increasing thermal energy efficiency. However, it is very difficult to reduce coke consumption while maintaining production, because the level of..... More

Corrosion Behavior of SiC and Si3N4 by Alkali Gas
알칼리 가스에 의한 SiC 및 Si3N4의 침식 거동
Ju-Hun Kim, Kang-Min Kim, Ji-A Lee, Jeong-il Kim, Jeong-Whan Han
김주훈, 김강민, 이지아, 김정일, 한정환
Korean J. Met. Mater. 2020;58(1):17-25.   Published online 2019 Dec 12
DOI: https://doi.org/10.3365/KJMM.2020.58.1.17

Studies of effective furnace cooling technology and refractory materials have extended the lifetime of a blast furnace to more than 15 years. On the other hand, the replacement of refractories in the blast furnace results in considerable cost and time loss for stopping the blast furnace operation. Various kinds of..... More

Charging Behavior of Sinter Feed according to Types of Charging Chute
장입 슈트 형태에 따른 소결 원료 장입 거동
Kang-Min Kim, Ki-Woo Lee, Jae-Hong Kwon, Hae-Kwon Jeong, Jeong-Whan Han
김강민, 이기우, 권재홍, 정해권, 한정환
Korean J. Met. Mater. 2017;55(12):896-904.   Published online 2017 Dec 4
DOI: https://doi.org/10.3365/KJMM.2017.55.12.896

In the iron ore sintering process, a thermal imbalance can occur in the sinter feed bed which degrades the quality of the sintered ores. In order to solve this thermal imbalance, it is necessary to control the sizes of the sintering feed charging through the chute by designing an appropriate..... More

Reduction Behaviors of Carbon Composite Iron Oxide Briquette Under Oxidation Atmosphere
산화성분위기에서의 탄재 내장 산화철 브리켓의 환원특성
Ki-Woo Lee, Kang-Min Kim, Jae-Hong Kwon, Sang-Han Son, Jeong-Whan Han
이기우, 김강민, 권재홍, 손상한, 한정환
Korean J. Met. Mater. 2017;55(1):24-30.   Published online 2017 Jan 5
DOI: https://doi.org/10.3365/KJMM.2017.55.1.24

The carbon composite iron oxide briquette (CCB) is considered a potential solution to the upcoming use of low grade iron resources in the ironmaking process. CCB is able to reduce raw material cost by enabling the use of low grade powdered iron ores and coal. Additionally, the fast reduction of..... More

Effect of Basicity on the Reduction Behavior of Carbon Composite Iron Oxide Briquette
탄재내장 산화철 브리켓의 환원거동에 미치는 염기도 영향
Jae-Hong Kwon, Eui-Hyuk Kwon, Ki-Woo Lee, Kang-Min Kim, Ji-A Lee, Jeong-Whan Han
권재홍, 권의혁, 이기우, 김강민, 이지아, 한정환
Korean J. Met. Mater. 2016;54(11):846-854.   Published online 2016 Nov 5
DOI: https://doi.org/10.3365/KJMM.2016.54.11.846

The world is gradually running short of high quality iron resources. This forces ironmaking processes to focus on the use of low quality iron ores. Carbon composite iron oxide briquettes (CCB) are one of the alternative choices. CCB enables the utilization of low quality powdered iron ores and coal, and..... More
