Description
본 발명은 점토벽돌의 제조방법에 관한 것으로서, 보다 구체적으로는 입도 조정 탈탄 슬래그를 점토벽돌 원료에 혼합하여 점토벽돌의 소성 변형율을 감소시킬 수 있는 점토 벽돌 제조방법에 관한 것이다.The present invention relates to a clay brick manufacturing method, and more particularly to a clay brick manufacturing method that can reduce the plastic strain of clay bricks by mixing the particle size adjustment decarburization slag to the clay brick raw material.
일반적으로 점토는 풍화, 분해과정에서 암석 내에 존재하는 규소, 알루미늄이 물과 결합하여 형성되는 것으로서, 열을 가하면 다시 암석처럼 단단하게 굳어지는 성질을 가지고 있다. 이와 같은 성질 때문에 점토는 도자기, 벽돌과 같은 건축자재, 내화물의 원료, 종이와 포와 같은 충진물 등 다양한 분야에서 사용되고 있다.In general, clay is formed by combining silicon and aluminum in the rock with water during weathering and decomposition, and has the property of hardening like a rock again when heat is applied. Because of this property, clay is used in various fields such as ceramics, building materials such as bricks, raw materials of refractory materials, and fillings such as paper and fabrics.
이 중 점토 벽돌은 일반적으로 점토와 규사를 주 원료로 하고, 상기 주 원료를 토련기를 이용하여 성형한 후, 건조, 소성하는 방법으로 제조된다. 종래에 일반적으로 사용되던 점토벽돌의 제조방법에 관하여는 일본공개특허 평6-72754호와 한국공개특허공보 제1995-0008410호에 기재되어 있다. 그러나, 상기 특허문헌에 기재되어 있는 방법으로 점토벽돌을 제조할 경우, 소성 변형율이 5 내지 10% 정도로 높게 나타난다는 문제점이 있다. 소성 변형율은 소성에 의한 수축, 팽창되는 정도를 나타내는 값으로서, 점토벽돌의 경우, 소성 후에 수축이 일어나는 것이 일반적이다. 소성 변형율이 높으면, 제품의 형태나 크기, 용량 등의 변형율이 커지기 때문에, 규격화된 제품의 생산이 어렵다는 단점이 있다.Among them, clay brick is generally produced by using clay and silica sand as main raw materials, and molding the main raw materials using a refining machine, followed by drying and firing. The clay brick manufacturing method generally used is described in Japanese Patent Laid-Open No. Hei 6-72754 and Korean Patent Publication No. 195-0008410. However, when producing a clay brick by the method described in the patent document, there is a problem that the plastic strain appears as high as 5 to 10%. The plastic strain is a value indicating the degree of shrinkage and expansion by firing. In the case of clay brick, shrinkage generally occurs after firing. If the plastic strain is high, the strain, such as the shape, size, capacity, etc. of the product is increased, there is a disadvantage that the production of a standardized product is difficult.
본 발명은 상기와 같은 종래의 문제점을 해결하고자 점토벽돌의 소성시 일어나는 소성 변형을 크게 감소시킬 수 있도록 점토 벽돌의 주원료에 대한 구성 성분으로서 입도 조정 탈탄 슬래그를 사용하여 소성 변형율이 매우 작은 점토 벽돌의 제조 방법을 제공하는데 그 목적이 있다.The present invention is to solve the conventional problems as described above by using a particle size adjustment decarburization slag as a constituent for the main raw material of clay brick to greatly reduce the plastic deformation occurring during the firing of clay bricks It is an object to provide a manufacturing method.
본 발명자는 상기와 같은 목적을 달성하기 위하여 연구를 거듭한 결과, 점토벽돌 원료에 입도 조정된 탈탄 슬래그를 이용하면 점토 벽돌의 소성 변형율을 크게 감소시킬 수 있음을 발견하고, 본 발명을 완성하였다.As a result of repeated studies to achieve the above object, the present inventors have found that the use of decarburized slag having a particle size adjusted to the raw material of clay brick can greatly reduce the plastic strain of clay brick, thereby completing the present invention.
구체적으로, 본 발명은 제1 구현예로서, 점토 및 50mm 이하의 입도를 갖는 탈탄 슬래그의 배합물에 물을 첨가하여 혼련하는 단계; 진공 토련하여 벽돌을 성형하고, 건조하는 단계; 소성하는 단계를 포함하는 점토벽돌 제조방법,Specifically, the present invention provides a first embodiment comprising the steps of kneading by adding water to the blend of clay and decarburized slag having a particle size of 50mm or less; Vacuum masonry to mold and dry the bricks; Clay brick manufacturing method comprising the step of firing,
제2 구현예로서, 상기 배합물은 점토 70 내지 40중량% 및 탈탄슬래그 30 내지 60중량5를 포함하는 것을 특징으로 하는 점토벽돌 제조방법,As a second embodiment, the formulation is a clay brick manufacturing method comprising 70 to 40% by weight of clay and 30 to 60% by weight of decarburized slag,
제3 구현예로서, 상기 소성온도는 1050℃ 내지 1150℃인 것을 특징으로 하는 점토벽돌 제조방법, 및As a third embodiment, the firing temperature is a clay brick manufacturing method, characterized in that 1050 ℃ to 1150 ℃, and
제4 구현예로서, 상기 소성 시간은 1 내지 24시간인 것을 특징으로 하는 점토벽돌 제조방법을 제공한다.As a fourth embodiment, the firing time provides a clay brick production method, characterized in that 1 to 24 hours.
본 발명은 점토, 규사, 석분 등으로 이루어진 종래의 점토벽돌 주원료에 입도 조정된 탈탄 슬래그를 특정 비율로 배합하여 사용함으로써 종래의 점토벽돌 제조방법에 비하여 소성 변형율을 크게 감소시킬 수 있다.The present invention can significantly reduce the plastic strain as compared to the conventional clay brick manufacturing method by using a mixture of decarburized slag adjusted in particle size in a specific ratio of the conventional clay brick main material consisting of clay, silica sand, stone powder.
또한, 본 발명은 입도 조정된 탈탄 슬래그의 배합비, 소성시간, 소성 온도 등의 조건을 조절함으로써 소성 변형율 감소를 극대화할 수 있다.In addition, the present invention can maximize the plastic strain reduction by adjusting the conditions such as the mixing ratio, the firing time, the firing temperature of the particle size adjusted decarburization slag.
이하 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.
일반적으로 점토벽돌을 제조하는 종래 방법은 점토와 규사 또는 석분 등의 주원료를 토련하고 건조시킨 후 소성하는데, 본 발명은 점토벽돌의 소성시 일어나는 소성 변형을 크게 감소 시킬 수 있도록 점토벽돌의 주원료에 대한 구성성분으로서 입도 조정 탈탄 슬래그를 사용하는 것에 그 특징이 있다.In general, the conventional method for producing clay brick is to sinter the main raw materials, such as clay and silica sand or stone powder, and then fired, and the present invention is to reduce the plastic deformation that occurs during the firing of clay bricks. It is characterized by using a particle size adjusting decarburization slag as a component.
본 발명에 따른 점토 벽돌의 재료로는 점토와 탈탄 슬래그의 배합물이다. 탈탄 슬래그는 소성 과정에서 결정화되면서 부피가 팽창되는 성질을 갖고 있기 때문에 점토와 함께 탈탄 슬래그를 첨가하면 소성 시 점토의 수축을 상쇄시킬 수 있어 벽돌의 소성 변화율을 감소시킬 수 있다. The material of the clay brick according to the invention is a blend of clay and decarburized slag. Since decarburized slag has the property of volume expansion as it is crystallized during firing, adding decarburized slag together with clay can offset the shrinkage of clay during firing, thereby reducing the plastic change rate of bricks.
이때 사용할 수 있는 탈탄 슬래그는 제강과정에서 얻을 수 있는 것이라면 특별히 한정하지는 않으나, 탈탄 슬래그의 입도는 5mm 이하로 입도 조정한 슬래그를 사용하는 것이 바람직하다. 따라서, 제강과정에서 얻어지는 탈탄 슬래그로서 5mm 미만의 것이라면 아무런 제한없이 사용할 수 있으며, 5mm를 초과하는 경우에는 분쇄하여 5mm 미만으로 한 후에 사용하는 것이 바람지하다. 탈탄 슬래그의 입도가 5mm를 초과하는 경우에는 점토와의 균일한 혼합이 어렵기 때문에 바람직하지 않으며, 나아가, 탈탄 슬래그의 결정화시 균일한 부피 팽창을 얻을 수 없는 바, 본 발명에서와 같이 5mm 이하의 입도 조정된 탈탄 슬래그를 사용하는 것이 바람직하다.The decarburized slag that can be used is not particularly limited as long as it can be obtained in the steelmaking process, it is preferable to use slag whose particle size is adjusted to 5 mm or less. Therefore, the decarburized slag obtained in the steelmaking process can be used without any limitation if less than 5mm, if it exceeds 5mm it is recommended to use after grinding to less than 5mm. If the particle size of the decarburized slag exceeds 5 mm, it is not preferable because it is difficult to uniformly mix with clay, and furthermore, it is not possible to obtain a uniform volume expansion during crystallization of the decarburized slag. Preference is given to using particle size adjusted decarburized slag.
이러한 탈탄 슬래그의 사용량은 30중량% 내지 60중량%의 범위로 첨가되는 것이 바람직하다. 탈탄 슬래그의 사용량이 30중량% 미만일 경우 점토벽돌의 소성 변형율 감소 효과가 충분하지 못하고, 탈탄 슬래그 사용량이 60중량%를 초과할 경우에는 슬래그의 결정화에 따른 팽창의 효과가 너무 크게 되어, 전체 변형율을 크게 하기 때문이다.The amount of such decarburized slag is preferably added in the range of 30% by weight to 60% by weight. When the amount of decarburized slag is less than 30% by weight, the effect of reducing the plastic strain of clay brick is not sufficient, and when the amount of decarburized slag is exceeded by 60% by weight, the effect of expansion due to crystallization of the slag becomes too large, thereby reducing the overall strain rate. It is because it enlarges.
상기 점토와 입도 조정된 탈탄 슬래그를 상기 범위의 함량을 갖도록 배합된 배합물에 물을 첨가하여 혼련한다. 이때 첨가되는 물의 함량은 15-25%의 수분 함량을 유지하도록 첨가하는 것이 바람직하다.The clay and the particle size-adjusted decarburized slag are kneaded by adding water to the blended formulation having a content in the above range. At this time, the amount of water added is preferably added to maintain the water content of 15-25%.
상기 혼련된 배합물을 토련기를 용하여 진공토련한 후, 원하는 크기외 형태로 성형하고, 100-150℃에서 2-7일간 건조시켜 성형품을 제조한다.The kneaded blend is vacuum drilled using a scouring machine, molded into a desired size, and dried at 100-150 ° C. for 2-7 days to produce a molded article.
상기 얻어진 성형품을 소성로에서 소성하여 목적으로 하는 벽돌을 얻는다. 이때, 소성 온도 범위는 1050℃ 내지 1150℃의 온도범위에서 소성하는 것이 바람직하다. 소성온도 1050℃ 미만인 경우에는 충분한 소성반응이 일어나지 않고, 1150℃를 초과하는 경우에는 성형체가 용융되기 때문에 상기 범위의 온도에서 소성하는 것이 바람직하다. 이때, 소성시간은 1시간 이상이면 충분하고, 그 이하에서는 균일하고 충분한 소성반응이 일어나지 않는다. 보다 바람직하게는 12 내지 24시간 동안 소성할 수 있다. 24시간을 초과하는 경우에는 에너지 소모가 많아 비경제적이다.The obtained molded product is fired in a firing furnace to obtain a target brick. At this time, the firing temperature range is preferably baked in a temperature range of 1050 ℃ to 1150 ℃. When the firing temperature is lower than 1050 ° C, sufficient firing reaction does not occur. When the firing temperature is higher than 1150 ° C, the molded body is melted, and therefore, firing at a temperature in the above range is preferable. At this time, the firing time is sufficient for 1 hour or more, and below it, a uniform and sufficient firing reaction does not occur. More preferably, it can be baked for 12 to 24 hours. If it exceeds 24 hours, energy consumption is high and it is uneconomical.
나아가, 소성 과정 완료 후에, 상기 소성된 제품은 냉각시킴으로써 최종적인 점토벽돌을 얻을 수 있다. 상기 점토벽돌은 급랭시키면 파벽이 발생될 수 있으므로, 6 내지 12시간에 걸쳐 서서히 냉각시키는 것이 바람직하다.Furthermore, after completion of the firing process, the fired product can be cooled to obtain a final clay brick. When the clay brick is quenched, a wave wall may be generated, and it is preferable to gradually cool the clay brick over 6 to 12 hours.
이하, 본 발명을 실시예를 통하여 보다 구체적으로 설명한다.Hereinafter, the present invention will be described in more detail with reference to Examples.
실시예 1Example 1
점토와 입도 조정 탈탄 슬래그를 아래 표 1과 같은 함량으로 배합하고, 각각의 배합물에 물을 첨가하였다. 이때, 함수율은 20%로 하였다. 그 후 토련기를 이용해서 120℃에서 5일간 진공 토련하여 성형한 후, 1150℃의 소성온도에서 5시간 동안 소성시킨 후, 10시간에 걸쳐 상온으로 서서히 냉각하여 점토벽돌을 제조하였다(발명예 1 및 2, 비교예 1 및 2). 이때, 탈탄 슬래그 함량에 따른 점토벽돌의 소성 변형율을 측정하였다. 그 측정 결과를 표 1에 나타내었다.Clay and particle size adjustment decarburized slag was blended in the amounts shown in Table 1 below, and water was added to each blend. At this time, the moisture content was 20%. Thereafter, by vacuum drilling at 120 ° C. for 5 days using a refining machine, and then firing at a firing temperature of 1150 ° C. for 5 hours, gradually cooling to room temperature over 10 hours to prepare a clay brick (Invention Example 1 and 2, Comparative Examples 1 and 2). At this time, the plastic strain of clay brick according to the decarburized slag content was measured. The measurement results are shown in Table 1.
[표 1]TABLE 1
상기 표 1에서 알 수 있는 바와 같이 탈탄 슬래그 함량이 30중량%(발명예 1), 60중량%(발명예 2)인 벽돌의 경우가 탈탄 슬래그 함량 20중량%와 70중량%인 벽돌의 경우에 비하여 소성 변형율이 거의 1/2 이하의 수준으로 크게 감소되었음을 알 수 있다.As can be seen in Table 1, in the case of the brick having a decarburized slag content of 30% by weight (invention example 1) and 60% by weight (invention example 2) of the brick having a decarburized slag content of 20% by weight and 70% by weight It can be seen that the plastic strain was greatly reduced to a level of almost 1/2 or less.
실시예 2Example 2
점토 40중량%와 입도 조정 탈탄 슬래그 60중량%를 가수 혼련하여 함수율 20%로 하고, 그 후 토련기를 이용해서 120℃에서 5일간 진공 토련하여 성형한 후, 1150℃의 소성온도에서 5시간 동안 소성시킨 후, 10시간에 걸쳐 상온으로 서서히 냉각하여 점토벽돌을 제조하였다. 이때, 1000℃ 내지 1200℃의 범위에서 소성온도를 달리하여 소성함으로써 소성온도에 따른 점토 벽돌의 변형율을 측정하였다(발명예 3, 4 및 비교예 3, 4). 그 결과를 표 2에 나타내었다.40% by weight of clay and 60% by weight of the particle size adjusting decarburized slag were hydroly kneaded to a water content of 20%, and then molded by vacuum drilling at 120 ° C. for 5 days using a refining machine, and then fired at a firing temperature of 1150 ° C. for 5 hours. After cooling, the clay brick was slowly cooled to room temperature over 10 hours. At this time, by varying the firing temperature in the range of 1000 ℃ to 1200 ℃ by firing was measured the strain of the clay brick according to the firing temperature (Invention Examples 3, 4 and Comparative Examples 3, 4). The results are shown in Table 2.
[표 2]TABLE 2
상기 표 2에 나타낸 바와 같이 1000℃의 소성온도에서 소성한 경우에는 충분한 소성이 일어나지 않았으며, 1200℃의 소성온도에서 소성한 경우에는 성형체가 용융되어 부정형으로 된 반면, 소성온도 1050℃ 및 1150℃에서 소성한 경우에는 소성 변형율이 낮은 벽돌이 얻어졌음을 알 수 있다.As shown in Table 2, when the firing was performed at a firing temperature of 1000 ° C., there was no sufficient firing. When firing at a firing temperature of 1200 ° C., the molded body was melted and became indefinite, whereas the firing temperatures were 1050 ° C. and 1150 ° C. When fired at, it can be seen that a brick having a low plastic strain was obtained.
실시예 3Example 3
점토 50중량%와 입도 조정 탈탄슬래그 50중량%에 함수율 20%로 가수 혼련하 여 얻은 배합물을 토련기를 이용하여 120℃에서 5일간 진공 토련하여 성형한 후, 소성온도 1150℃에서 소성하고, 10시간에 걸쳐 상온으로 서서히 냉각하여 점토벽돌을 제조하였다. 이때, 소성시간을 30분 내지 9시간의 범위에 변화시킴으로써, 소성시간에 따른 점토벽돌의 변형율을 확인하였다(발명예 5 내지 8 및 비교예 5). 그 측정 결과를 표 3에 나타내었다.50% by weight of clay and 50% by weight of particle size-adjusted decarburized slag were hydroly kneaded at a water content of 20%, and then vacuum-molded at 120 ° C. for 5 days using a refining machine, followed by firing at a baking temperature of 1150 ° C. for 10 hours. Slowly cooled to room temperature over to prepare a clay brick. At this time, by changing the firing time in the range of 30 minutes to 9 hours, the strain of the clay brick according to the firing time was confirmed (Inventive Examples 5 to 8 and Comparative Example 5). The measurement results are shown in Table 3.
[표 3][Table 3]
표 3에 나타낸 바와 같이 소성이 30분인 경우에는 벽돌의 소성이 불완전하게 나타났으며, 1시간 이상인 경우에 소성 변형율이 1% 이하로서 소성 변형율 감소 효과가 크게 나타남을 알 수 있었다.As shown in Table 3, when the firing time is 30 minutes, the sintering of the bricks is incomplete, and when the firing rate is 1 hour or more, the plastic strain rate is 1% or less, which shows that the plastic strain reduction effect is large.
