Description
본 발명은 냉각후 팽창, 붕괴성을 갖고 있기 때문에 에이징처리 후, 일부 노반재 등으로 이용되고 있지만, 대부분은 매립폐기 처분되고 있는 것이 현상인 제강스라그의 유효이용에 관한 것이다.The present invention is used as a part of roadbed material after aging treatment because of its expansion and collapse after cooling. However, most of the present invention relates to the effective use of steelmaking slag, which is a phenomenon in which landfills are disposed of.
제강스라그에는 각종의 것이 있지만, 본원 발명에서는 전로스라그, 전기로스라그(산화기)를 대상으로 한다.There are various kinds of steelmaking slag, but in the present invention, a total loss slag and an electric loss slag (oxidizer) are targeted.
일반적으로 제강스라그는 2CaO·SiO2, F·CaO, F·MgO, 2CaO·Fe2O3, 4CaO·Al2O3·Fe2O3, Fe2O3, Fe3O4, FeO 등을 함유하고 있기 때문에 잠재수경성을 갖고 있지 않으며, 고로스라그는 서냉처리하면 메리라이트(2CaO·Al2O3·SiO2- 2CaO·MgO·2SiO2의 중간성분)와 CaS를 갖고, 급냉하면 그라스주체로 되어 잠재수경성을 가져서 고로시멘트 혼화재등에 이용되고 있다.Generally, steelmaking slag is composed of 2CaO · SiO 2 , F · CaO, F · MgO, 2CaO · Fe 2 O 3 , 4CaO · Al 2 O 3 · Fe 2 O 3 , Fe 2 O 3 , Fe 3 O 4 , FeO, etc. not to not have a latent hydraulic because it contains, and Los ln when annealed Mary light (2CaO · Al 2 O 3 · SiO 2 - 2CaO · MgO · medium components of 2SiO 2) and has a CaS, when quenched glass It is mainly used for blast furnace cement admixtures due to its potential hydraulic properties.
현재, 이와같은 제강스라그는 스라그팬(Slag Pan)에 받아서 약 20분-12시간 후에 배출되고 있지만 약 200-300℃로 되면 2CaO·SiO2가 β→γ로 전이할 때에 팽창붕괴하거나 FCaO·FMgO를 함유하기 때문에 팽창 붕괴성을 갖고 있어 상기와 같이 대부분은 매립 폐기되고 있다.Currently, such steelmaking slag is discharged after being received by slag pan for about 20 minutes to 12 hours, but when it reaches about 200-300 ° C, it expands or collapses when 2CaO · SiO 2 transitions from β → γ. Since it contains FMgO, it has expansion and collapse property, and most of it is disposed of as landfill as described above.
본 발명은 상술한 결점을 해소하고 유효 이용하는 방버에 관한 것으로 α'-β-22CaO·SiO2주체 또는 그라스주체, 혹은 1부 α'-β-22CaO·SiO2와 그라스주체로 되도록 수재로 하여 건조후 분쇄하고 알카리자극제(예를들면, CaO, Ca(OH)2, Na2CO3, CaCl2, NaOH 등)를 소량 첨가하여 물을 가해서 혼연하면 수경성을 갖는다는 사실을 발견하였다.The present invention relates to a method for solving the above-mentioned drawbacks and effectively using the α'-β-22CaO.SiO 2 main body or the glass main body, or 1 part α'-β-22CaO.SiO 2 and the glass main body so as to be dried. After crushing and adding alkaline stimulants (eg, CaO, Ca (OH) 2 , Na 2 CO 3 , CaCl 2 , NaOH, etc.) in small amounts, water was found to be hydrophobic.
또 그의 분말도가 클수록, 급속하게 경화하는 것도 발견하였다.Moreover, it discovered that it hardened rapidly, so that the powder degree was large.
그리고, 전로스라그라 하드라도 화학성분상 철분이 비교적 적은 것도 발생하고 있으며 전기로스라그도산화기와 환원기를 같이 내는 (One Slag 방법) 방법도 있고, 철분이 어느 정도 함유되어 서냉하여 2CaO·Fe2O3, 4CaO·Al2O3·Fe2O3가 생성하는 성분으로 개질처리 후, 수재화한 것이 강도가 있다.In addition, there is also a relatively small amount of iron in the chemical composition, even in the case of all loss lagra hard, there is also a method of producing the electric loss lag oxidizer and a reducing group together (One Slag method), the iron is contained to some extent slow cooling to 2CaO · Fe 2 O 3, 4CaO · Al 2 O 3 · a is the strength after the modification treatment in which the components produced Fe 2 O 3, number of goods.
화학성분은 범위가 비교적 넓고, 고염기도 때문에 융점이 높고 수재율이 감소하는 경우도 있다.The chemical composition is relatively broad in scope, and in some cases, the melting point is high and the yield rate decreases because of the high base.
또한 규산염질의 암석, 광물 등을 첨가하여 주체로부터 α'-β-2CaO·SiO2주체로부터 2CaO·SiO2-2CaO·MgO·2SiO2주체로 개질하면 융점점성은 내리고 수재율도 향상하여 그라스주체가 되어 건조 후 분쇄해서 알칼리 자극제(예를들면 CaO, Ca(OH)2, 시멘트 등)를 소량 첨가해서 물을 가해서 훈련하면 수경성을 갖는다는 것을 발견하였으며, 진흙(Mud) 고화강도의 발현을 균일화하기 위하여 규산염질의 암석, 광물등을 첨가하는 것이다.In addition, when silicate rocks, minerals, etc. are added to the α'-β-2CaO · SiO 2 principal to 2CaO · SiO 2 −2CaO · MgO · 2SiO 2 to reduce the melting point and improve the yield, the glass becomes the main agent. After drying, grinding and adding small amounts of alkali stimulants (e.g. CaO, Ca (OH) 2 , cement, etc.) to water and training were found to have hydraulic properties, in order to equalize the expression of mud solidification strength. Silicate rock, minerals, etc. are added.
첨가물로서는 Al2O3, SiO2단독으로서도 좋지만 용융온도가 높고 반응이 생기기 어렵다는 결점이 있기 때문에 SiO2, Al2O3, Fe2O3등을 적량 함유하는 것을 첨가하므로서 용융온도의 저하를 촉진하고, 반응이 충분히 일어나도록 하는 것이다.As the additive, Al 2 O 3 and SiO 2 alone may be used. However, since the melting temperature is high and the reaction hardly occurs, the addition of an appropriate amount of SiO 2 , Al 2 O 3 , Fe 2 O 3, etc. is added to promote the reduction of the melting temperature. And the reaction is sufficient to occur.
첨가물의 첨가방법은 다음과 같다.The addition method of an additive is as follows.
1. 제련로내에 제련의 최초 또는 도중에 투입한다.1. Put into the smelting furnace at the beginning or middle of smelting

6. 배재남비내에서 용재와 샌드위치상이 되도록 투입한다.6. Into the ash pot, put it in the form of a sandwich and a sandwich.
7. 3,4,5,6의 조작으로 투입하여 란스파이프(Lance Pipe)상 물을 삽입하고, 버브링가스(Bubbling Gas)(O,N 또는 Air)를 불어 넣어서 확산시킨다.7. Insert 3, 4, 5, 6 and insert water on the lance pipe, and blow the blowing gas (O, N or Air) to diffuse it.

이하 본 발명방법의 작용효과를 확인하기 위하여 행했던 실험 및 그의 효과를 표시한다.The following experiments and effects thereof were conducted to confirm the effect of the method of the present invention.
실험에 사용한 시료의 화학분석치, 성상을 제1표에 표시한다.The chemical analysis values and properties of the samples used in the experiment are shown in the first table.
[제1표][Table 1]
붕괴율은 제강스라그(A)는 35.0%, 제강스라그(B)는 6.5%, 고로수재는 0.2%이었다.The decay rate was 35.0% for steelmaking slag (A), 6.5% for steelmaking slag (B), and 0.2% for blast furnace wood.
또, 붕괴율은 ASTM법(20kg/cm-1, 200℃, 3시간 보지)으로 10-25mm의 사이즈로 처리하고 10mm 이하를 붕괴율로 하였다.In addition, the disintegration rate was treated with an ASTM method (20 kg / cm -1 , 200 ° C, 3 hours holding) in a size of 10-25 mm, and 10 mm or less was used as the disintegration rate.
*1 제강스라그와의 비교를 위해서 나타냈다.* 1 Shown for comparison with steelmaking slag.
우선 제2표에 각 시료의 법합비율(중량 %)을 표시한다.First, the legal ratio (weight%) of each sample is shown in a 2nd table.
[제2표][Table 2]
다음으로 제3표에 각 시료의 배합물의 용도온도(JIS법에 의한 Seger's Cone)를 표시하였다.Next, the application temperature (Seger's Cone by JIS method) of the compound of each sample was shown in the 3rd table | surface.
[제3표][Table 3]
상기의 시료를 항온건조기(105-110℃로 보지) 중에서 24시간 이상 건조 후, 전용 마그네시아도가니(Crucible for Induction Furnaces Fused Magnesia)에 500g을 넣어서 실리콘 카바이드 전기로(Silicon Carbide Electronic Heating Element) (1550℃로 보지)로 재용해해서 로외로 끌어내어 수중에서 냉각하여 수쇄하고, 건조후 약 200맷슈 이하로 분쇄해서 석회를 3 중량 % 첨가 혼합해서 물을 가하여 혼련한 후 비닐봉지에 넣어서 밀봉하고, 경화상태를 조하해서 제4표에 표시한다. 화학분석치, 생성광물 등에 관해서 조사하여 제5표에 표시한다.After drying the sample in a constant temperature dryer (holding at 105-110 ℃) for more than 24 hours, 500 g in a dedicated magnesia crucible (Crucible for Induction Furnaces Fused Magnesia) and Silicon Carbide Electronic Heating Element (1550 ℃) Redissolved, and then drawn out of the furnace, cooled in water, crushed, dried, pulverized to about 200 mms or less, mixed with 3% by weight of lime, mixed with water, kneaded, sealed in a plastic bag, and cured. Calculate and mark in the fourth table. The chemical analysis values, the minerals produced, etc. are investigated and displayed in the fifth table.
[제4표][Table 4]
그리고 ◎는 손으로 눌러서 매우 단단한 것. ○는 단단한 것. △는 약간 단단한 것. ×는 경화되어 있지 아니한 것을 표시함.And ◎ is very hard to press by hand. ○ is hard. △ is a little hard. × indicates that it is not cured.
또 수재화했던 시작스라그는 거의가 급결되어 약 10-20분 후부터 경화하기 시작했다.The starting slag, which had been re-hydrated, was almost quickly cured and started to harden in about 10-20 minutes.
[제5표][Table 5]
상기와 같이 규산염질의 암석, 광물등을 첨가하면, 스라그의 고화온도가 저하하고 또한 2CaO·SiO2의 정출도 적게 되어 수재화하므로서 그라스화도 촉진된다.When silicate rocks, minerals, and the like are added as described above, the solidification temperature of slag is lowered and crystallization of 2CaO.SiO 2 is reduced, so that the glass is promoted while re-watering.
또 재강스라고 단독의 수재화보다 빨리 경화한다. 이 첨가물을 첨가 후, 수재화한 스라그의 주함유물은 그라스주체로서 β 및 α'-2CaO·SiO2를 함유하고 있지만 첨가물을 미첨가한 경우에는 그라스와 β-2CaO·SiO2주체이다.In addition, it hardens more quickly than rehydration alone. After addition of this additive, the main contents of the regenerated slag contain β and α'-2CaO · SiO 2 as the glass main body, but the glass and β-2CaO · SiO 2 main body when the additive is not added.
이 수재화한 스라그를 보통 포오트란드시멘트 크린카량의 5,10,20 중량 % 치환(置煥)하고 또한 이 혼합물 100 중량 %에 대하여 석고를 3 중량 % 배합해서 볼밀로 브렝니치, 약 3,200cm2/g 및 5,700cm2/g등으로 분쇄해서 JIS법에 의한 몰탈시험, 페이스트에 의한 시험을 하고 제6표에 표시한다. 그러나 석회의 함유량을 10% 이상을 써서 몰탈, 페이스트로 해서 24시간 후에 수중양생시킨면 수화반응이 충분치 못하여 붕괴하는 수가 있다.This hydrated slag is usually substituted by 5,10,20% by weight of the amount of poland cement cement, and 3% by weight of gypsum is added to 100% by weight of this mixture. by grinding in cm 2 / g and 5,700cm 2 / g and so on and displays the mortar test and tested by the paste according to the JIS method, and a sixth table. However, if the content of lime is mortar or paste using 10% or more of water and cured in water after 24 hours, the hydration reaction may not be sufficient and may collapse.
7일 정도 습공양생 후 수중양생을 하게 되면 이와같은 현상은 없어진다.After seven days of wet curing and underwater curing, this phenomenon disappears.
[제6표][Table 6]
상술한 바와같이 본원 발명에 의하면, 용융상태의 스라그에 규산염질의 암석, 광물등을 첨가해서 용융확산 반응을 생기게 하고, 수중에서 급냉 수재화하여 건조후 시멘트 크린카에 혼합해서 분쇄하거나, 단독 분쇄물을 혼합하거나, 고로수재의 일부를 바꾸어 사용하여 혼합시멘트로서 이용 가능하며, 제강스라고 단독으로부터의 수재물보다 융점 점성저하를 일으키게 하기 때문에 규산염질의 암석등을 첨가하면 강도도 강하다.As described above, according to the present invention, silicate rocks, minerals, and the like are added to the molten slag to cause a melt diffusion reaction, quenched in water, dried, mixed with a cement cleaner, and pulverized, or crushed alone. Water can be mixed or a part of the blast furnace material can be used as a mixed cement, and since the melting point viscosity is lowered than the steel from steelmaking alone, the addition of silicate rock etc. is also strong.
또 페이스트(Paste) 시험으로서는 약 10분 정도로 경화를 시작하기 때문에 단광과 페렛드(Pellet)의 바인다로서 가능하다.In addition, as the paste test starts curing in about 10 minutes, it is possible as a binder of briquettes and pellets.
