산소일수증기 흡입 제철에 관한 연구

양훈영 대한금속재료학회(대한금속학회) 1969 대한금속·재료학회지 Vol.7 No.3

현금의 제철법을 간접제철법과 직접제철법의 두가지로 크게 나눌 수 있다. 이 중 대부분의 철은 전자에 속하는 코크스 용광로법에 의하여 생산되고 있다. 이 코코스용광로법은 오랜 역사를 가짐과 동시에 그 생산성과 경제성은 다른 제철법의 추종은 불허하는 중요한 위치에 있다. 그럼에도 불구하고 이 제철법은 막대한 건설자금과 대용량화가 필요하며 더우기 나라에 따라서는 전연 없거나 고갈해가는 코크스원료인 점결탄을 필요로 함과 동시에 장입원료에 요구되는 조건들이 엄격한 등의 결점을 가지고 있다. 현재 대량의 산소의 사용이 철강공업 특히 제강분야에 보편화 되어가고 있다. 제철분야에 있어서의 산소의 이용은 산소부화 공기의 사용과 최근 발표되고 있는 Stora 회전로법 정도이다. 여기에서는 순산소를 가장 열효율이 높은 직립로에 사용함으로써 적은 투자와 소규모로 제철할 수 있고 원료조건도 비교적 완화되는 제철법을 모색하고자 시험을 하였다. 기초실험과 산소-수증기 취입시험에서 얻은 결과는 다음과 같다. (1) H₂와 CO로 된 혼합가스에 의한 광석의 환원속도는 H₂ 함량이 클수록 크며 H₂ 40∼50%까지의 혼합가스가 환원력이 크다. (2) 환원온도와 가스유량이 클 수록 환원속도가 빠르며, CO₂, N₂ 함량이 적을 수록 환원력은 크다. (3) 산소 취입시의 수증기의 첨가량이 적을수록 H₂, CO₂함량은 적어진다. (4) 노정가스중의 CO, H₂ 함량은 보통의 용광로 가스보다 많으며 CO₂를 제거한 청정가스는 보조연료로서 재사용이 가능하다. A preliminary study has been made of the reduction by mixtures of CO and H₂ of natural hematite ore. Effects of gas composition, temperature, and gas flow rate on the reduction rate were studied. Preferable reduction performance was achieved with an elevated temperature, a H₂ rich gas mixture, and increased gas flow rate. Based on the preliminary work, a larger scale test in a low shaft vessel with ore burden and coke, into which an oxygen-steam blast was blown, has also been made to approach the physical chemical behavior to the practical operation. From the test, it was evaluated that shaft furnace for iron ore reduction could be shortened in its height than conventional blast furnace, since the temperature gradient in the shaft vessel was so steepened and bosh gas composition was much more powerful than that of blast furnace. A proposed sheet was attempted fox the ironmaking process with oxygen-steam blast, using cleaned top gas as an auxiliary fuel, excluding blast hot stove, causing decreased coke ratio and increased production.

韓國 製鐵 工業의 展望

梁勳永 全北大學校 1958 論文集 Vol.2 No.-

The Government of the Republic of Korea has established an annual goal of 200,000 tons for domestic steel production. In spite of such a production project, the building up of the iron industry on the basis of the domestic mineral resources and conditions prevailing in the country faces a number of obstacles from the technical point of view. The Government, therefore, has repeated joint discussions with Korean technicians and representatives of the Government authorities concerned for the solution of the prevailing difficulties. In the meantime, in march 1956, Mr. W. S. Riu who is Managing-Director of the Daihan Heavy Industry Corporation was instructed to proceed west Germany, entrusting with a study of the adoptable iron and steel making process on the basis of the domestic materials. In addition, In may 1956, the government invited prof Lu¨th of Aachen University to ask his opinion for the possibilities of building up an iron industry in our country. Prof. Ku¨th submitted his findings in a report ofter conducted field surveys. He proposed to erect 3 electric pig iron furnaces with a daily capacity of 150 to 170 tons each in Mookho, and Stu¨rgelberg process with 50 tons capacity, he argued, might be adequate so for as the inchon plant was concerned. In the steel making process, he recommended to erect 3open-hearth furnaces of 50 to 60 ton capacity each, which vtilige the surplus gas from the electric pig-iron furnaces as fuel. For his recommendation, however, I have expressed my opinion on the college paper that the electric reducing furnace and Stu¨rzelberg process would not suitable in our country because of its higher processing cost and deficiency of electric power. I submitted that the blast furnace process might be adopted successfully if the production of artificial coke by domestic anthracite has been materialized, however, in the existing circumstances being not yet aceomplished the form coke test, the DEMAG-Humboldt process would be the most suitable method as the right advantage in our country, and concerning the steel making process it is benificial to adopt the duplex process-the combined Bessener and basic open-hearth process-which promote fuel economy by shortening the purification time and makes the steel maker independent of the steel serap. Subsequently, in May 1957, I received a report from Mr. W. S. Riu who had returned home from west Germany. He proposed a blast furnace process using artificial coke on the basis of his tests for the production of blast furnace coke from domestic anthracite. On the other hand, he recommended an oxygen-blown converter process as the steel production method. His observation and recommendation in connection with developing an iron and steel industry in Korea is so favorable and practicable that I should like to introduce his suggestions to our students and civilian technicians and, added to this, would give my own impressions.

ESR 법에 의한 Cu-Pb 합금의 조직과 마모특성에 관하여

양훈영,민동준 대한금속재료학회(대한금속학회) 1984 대한금속·재료학회지 Vol.22 No.10

Experiments were carried out to investigate the effects of various casting methods and ESR, together with the addition of 2% nickel and 1% tin on the structure and wear properties of Cu-Pb alloy. The results obtained are as follows; 1) Inter-rod spacing of lead in ESR ingot was inversely proportional to the square root of solidification rate. 2) Wear resistivity of ESR ingot was superior to that by sand castings or chill castings. 3) Wear mechanism of Cu-Pb alloy seemed to be metallic and melting wear, no oxidizing wear was appreciable. Therefore, wear amount increased with increasing sliding speed.

Solubility of nitrogen in liquid iron, iron-chromium and iron-nickel alloys has been measured by the sampling method under 1 atm N₂pressure. Experiments were carried out at the temperature range of 1829-2205K and at the composition range of 0-30.2% Cr and 0-40.0% Ni. Results obtained are as follows: 1) Nitrogen solubility measured in pure iron was, log (wt % N)_Fe=-341/T-1.157. 2) Interaction parameters in liquid Fe-Cr and Fe-Ni alloys were, 3) Enthalpy change of nitrogen solubility in Fe-Cr and Fe-Ni slloys were,
