한식형 그을림 기와의 고밀도 침탄층 형성을 위한 소지조성물 및 한식형 그을림 기와 제조방법{The tan tile Korean style shape for high density character a composite and Korean style shape tile making process}The composition of Korean style and Korean style shape tile making process for forming a high-density carburized layer with Korean-style burnt tile

본 발명은 한식형 그을림 기와에 고밀도 침탄층을 형성하기 위한 소지조성물과 한식형 그을림 기와 제조방법에 관한 것이며 한식형 그을림 기와에 압축 강도를 높이고 내마모성과 수분 흡수율을 낮추어 고품질의 한식형 그을림 기와를 제공할 수 있도록 한 것이다.The present invention relates to a base material composition for forming a high-density carburized layer on the Korean-style burned roof tile and a method for manufacturing a Korean-style burned roof tile to provide high quality Korean-style burned roof tile by increasing the compressive strength and lowering the wear resistance and water absorption rate It is to be done.

한식형 그을림 기와는 점토를 주원료로 하고, 자화 공정에서 휨이나 뒤틀림을 방지하고, 색상을 발현하기 위하여 규사나 백토, 고령토 등의 부원료를 사용하여 소지조성물을 제조하고, 상기 소지로 기와를 성형한 후 건조하고 이를 1,000~1,200℃의 온도에서 1~2시간을 소성하고, 900~950℃에서 환원소성으로 탄화처리하여 제조된다.Korean-style burned roofing tile is made of clay as the main raw material, and prevents warping and warping in the magnetization process, and uses a subsidiary material such as silica sand, clay, kaolin, etc. After drying, it is calcined at a temperature of 1,000 to 1,200 ° C. for 1 to 2 hours and carbonized at 900 to 950 ° C. under reduced firing.

상기의 기와는 원료의 내화도가 증가 되어 소성온도가 높아지면서도 점토 특유의 치밀한 침상입자 구조가 부원료의 투입으로 불안정한 구조로 변화되어 압축 강도는 3,200~3,500g/㎟이고, 수분 흡수율은 4~7%이고, 내마모성은 0.08~0.09g이어 서 압축강도와 내마모성이 취약하게 되어 우수기에는 기와에 수분이 흡수되어 지붕 하중이 무거워지거나 결빙되는 동절기에는 강도 취약으로 파손되는 등의 결점과 고온에서의 장시간 소성으로 제조원가가 높아지는 결점을 수반하고 있다.As the fire resistance of the raw materials increases, the firing temperature increases, and the dense needle-like structure peculiar to clay is changed into an unstable structure due to the input of secondary raw materials, and the compressive strength is 3,200-3,500 g / mm2, and the water absorption rate is 4-7%. The wear resistance is 0.08 ~ 0.09g, which makes the compressive strength and the wear resistance weak, so that moisture is absorbed by the tile in the rainy season and the roof load becomes heavy or breaks due to the weak strength in the winter season. This is accompanied by the drawback that the manufacturing cost increases.

상기와 같은 종래의 제반 결점을 해소하기 위한 여러가지 연구가 이루어지고는 있으나 그 해결 방안은 해소되지 못하고 있다.Various researches have been made to solve the above-mentioned general drawbacks, but the solution has not been solved.

또 한식형 그을림 기와 및 한식 토기와에 관한 선행기술은 아래와 같다.In addition, the prior art related to Korean-style burned roof tiles and Korean earthenware tile is as follows.

본 발명은 상기와 같은 종래의 제반 결점을 해소하고 주원료인 점토에 부원료인 규사, 백토 사용을 중단하고, 고령토의 사용을 최소화하고 산화철을 함유시켜서 소지조성물을 구성하고, 상기 소지조성물로 기와를 성형하고 건조 후 산화소성 및 환원소성 공정에서 산화철을 자화시켜서 고밀도 침탄층을 형성시켜서 고강도이고 수분 흡수율과 내마모성은 낮추어 고품질의 그을림 기와를 제공하고, 산화소성 온도를 낮추고 소성시간을 단축하여 그을림 기와의 제조원가를 낮출 수 있도록 하기 위한 목적이다.The present invention solves the above-mentioned conventional drawbacks and stops the use of silica, white clay as an auxiliary material in clay, which is the main raw material, minimizes the use of kaolin and comprises iron oxide to form a base composition, and forms a tile with the base composition. After drying, the iron oxide is magnetized in the oxidizing and reducing firing process to form a high density carburized layer, which is high strength, lowers the water absorption rate and abrasion resistance, provides high quality burned roof tiles, lowers the oxidizing temperature and shortens the firing time, thereby producing the burned roof tiles. The purpose is to lower the.

본 발명에서 보인 도1은 제조공정도이다.1 is a manufacturing process diagram shown in the present invention.

본 발명은 점토와 고령토 및 산화철을 90~93 : 5~8 : 2~4의 중량비율(%)로 혼합하여 한식형 그을림 기와 소지조성물을 구성하고, 상기 소지조성물로 한식형 그을림 기와 성형기의 성형틀에서 기와를 성형하고 이를 건조시킨 다음 소성로에 넣고 1,070~1,080℃의 온도에서 50분간을 유지시켜서 산화소성 한 후 냉각하면서 900~950℃에서 LNG가스를 500mmAq이상으로 20~30분간을 분사하여 환원소성을 수행한 다음 상온으로 냉각시켜서 한식형 그을림 기와를 제조한다.The present invention mixes clay, kaolin and iron oxide in a weight ratio (%) of 90 to 93: 5 to 8: 2 to 4 to constitute a Korean-style seared group and a base composition, and the base composition is a molding of a Korean-type seared group and a molding machine. After forming the tile in the mold and drying it, put it in the kiln and keep it for 50 minutes at the temperature of 1,070 ~ 1,080 ℃ to oxidize and reduce the cooling by spraying 20 ~ 30 minutes of LNG gas over 500mmAq at 900 ~ 950 ℃ while cooling. Baking is performed and then cooled to room temperature to prepare a Korean-style seared tile.

상기와 같은 본 발명의 한식형 그을림 기와는 소지의 조성이 간단하고 주원료인 점토에 혼합된 산화철(Fe₂O₃)은 기와의 제조공정인 산화소성 공정과, 환원 소성 공정에서 자화속도를 신속하게 하고, 저온에서 자화되면서도 치밀한 구조를 갖게 되므로 그을림 기와의 소성공정에 소요되는 연료비를 절감할 수 있게 된다.As described above, the Korean-style seared tile of the present invention is simple in composition and iron oxide (Fe₂O₃) mixed in clay, which is a main raw material, has a rapid oxidation rate in the firing process, and a reduction firing process, which is a manufacturing process of the tile. The magnetization at and yet has a compact structure can reduce the fuel cost required for the baking process of the burner tile.

또 주원료인 점토에 산화철이 혼합상태에서 신속하게 자화되고 산화환원 공정(탄화처리)에서 그을림 기와의 표면에 고밀도 침탄층이 형성되어 내마모성 및 수분 흡수율이 낮게 되며 상기 그을림 기와로 지붕을 시공하게 되면 결빙기에 기와에 흡수된 수분의 결빙으로 파손되는 요인과, 우수기에 그을림 기와에 수분 흡수로 인하여 기와의 무게가 증가 되는 요인과, 그을림 기와의 운반과 시공과정에서 강도 취약으로는 파손되는 결점이 없고, 그을림 기와로 시공된 건축물은 장구히 보존할 수 있게 되는 이점이 있다.Also, iron oxide is rapidly magnetized in the mixed state of clay, which is the main raw material, and a high-density carburized layer is formed on the surface of the burned-up tile in the redox process (carbonization treatment), resulting in low abrasion resistance and water absorption rate. There is no defect that is damaged by the freezing of moisture absorbed in the roof tiles, the weight of the roof tiles due to the absorption of moisture in the seaweed roof tiles during the rainy season, and the weakness in strength during the transport and construction of the seaweed roof tiles. The building constructed with the burned roof tile has the advantage of being able to be preserved for a long time.

본 발명의 구체적인 실시 예를 설명하면 다음과 같다.Hereinafter, specific embodiments of the present invention will be described.

제1공정(원료배합 공정)First step (raw material blending step)

주원료인 점토와 고령토 및 산화철을 중량비율(%)로 하여 90~93 : 5~8 : 2~4% 배합하고 균질화 되게 반죽하여서 한식형 그을림 소지조성물을 제조한다.A Korean-style grilled composition is prepared by mixing 90-93: 5-8: 2-4% of clay, kaolin and iron oxide as main components by weight ratio and kneading homogeneously.

상기에서 사용 점토는 화학성분 분석을 통해 산화철(Fe₂O₃) 성분이 높은 점토를 사용하고 입도는 1mm이하로 한다.The clay used in the above uses a high iron oxide (Fe₂O₃) component through chemical analysis and the particle size is 1mm or less.

(일반적으로 2차 점토의 산화철 함유량은 4%미만이므로 산화철을 부원료로 추가 투입하여 총 조성물의 5~7%가 함유되게 한다.)(In general, the iron oxide content of secondary clay is less than 4%, so iron oxide is added as a subsidiary material so that 5 to 7% of the total composition is contained.)

상기에서 부원료로 투입하는 산화철은 기와를 산화소성 및 환원소성 공정을 수행할 때 자화를 신속하게 진행하기 위한 융제(FLUX)로 작용한다.The iron oxide introduced as an auxiliary material serves as a flux (FLUX) for rapidly advancing magnetization when the roof tiles are subjected to an oxidizing and reducing firing process.

또 부원료의 하나인 고령토는 산화철의 투입으로 인한 적색의 발색을 제어하기 위한 목적과, 내화도의 균형을 유지하여 휨 및 뒤틀림을 억제하기 위한 용도로 투입되어 점토성분과 유사한 구조적 특성으로 구조적인 안정화하게 된다.Kaolin, one of the subsidiary materials, is used for the purpose of controlling the color development of red due to the addition of iron oxide, and for the purpose of controlling the balance of fire resistance and suppressing warping and warping, so that the structural stability is similar to the clay component. do.

제2공정(성형공정)2nd process (molding process)

제1공정의 한식형 그을림 기와 소지조성물을 한식형 그을림 기와 성형기의 성형틀에 일정량씩 넣어 성형하고 성형 된 기와는 건조한다.The Korean-style searing machine and the base composition of the first process are put into a mold of the Korean-style searing machine and the molding machine by a predetermined amount, and the formed tile is dried.

제3공정(3rd process 산화소성Oxidative Oxidation 공정) fair)

제2공정을 거쳐서 성형 건조된 기와는 소성로에 넣고 상기 소성로의 내부 온도가 1,070~1,080℃가 되도록 하고, 상기 온도에서 50분간을 유지하여 산화소성 한다.The roof tile formed through the second step is placed in a kiln, so that the internal temperature of the kiln is 1,070 to 1,080 ° C, and maintained at the temperature for 50 minutes to oxidize.

상기 온도에 이르면 산화철은 자화가 이루어지게 된다.When the temperature is reached, the iron oxide is magnetized.

제4공정(4th process 환원소성Reducing firing 공정) fair)

제3공정이 경료되면 냉각 단계로 전환시켜 소성로의 내부온도가 900~950℃에 이르면 LNG 가스를 500mmAg이상의 압력으로 20~30분간을 분사시켜서 환원소성(탄화처리) 한다.When the third process is completed, the process is switched to the cooling stage. When the internal temperature of the kiln reaches 900 to 950 ° C., the LNG gas is sprayed at a pressure of 500 mmAg or more for 20 to 30 minutes to reduce baking (carbonization).

상기 환원소성은 종래 보다는 10~20분이상 길어지게 되면 침탄을 집중시켜서 그을림 기와의 표면에 고밀도 침탄이 이루어지게 된다.When the reducing firing is longer than 10 to 20 minutes longer than before, the carburizing concentrates the carburizing, and thus the high density carburizing is made on the surface of the burning roof.

제5공정(냉각 및 5th process (cooling and 제3화공정Episode 3 Process ))

제4공정이 완료되면 강제 냉각하고 500℃에 이르면 소성로의 문을 개방하여 자연 냉각시키고 상온에 이르게 되면 소성로내의 기와를 인출하여 상품화한다.When the fourth step is completed by forced cooling, when the temperature reaches 500 ° C, the door of the kiln is naturally cooled, and when it reaches room temperature, the tile in the kiln is drawn and commercialized.

상기와 같은 본원발명에서 제1공정으로 조성된 소지조성물은 종래에 비하여 산화소성 공정에서 소성온도를 50~100℃로 낮출 수 있고, 산화소성 시간도 10분~1시간을 단축할 수 있어 연료비를 절감하여 제조원가를 낮출 수 있게 된다.In the present invention as described above, the base material composition prepared in the first step can reduce the firing temperature to 50 to 100 ° C. in the oxidizing step, and the oxidizing time can also be reduced to 10 minutes to 1 hour, compared to the conventional method. Reduction in manufacturing cost can be achieved.

또 상기 한식형 그을림 기와 소지 조성물로 기와를 성형하고 산화소성과 환원소성을 거쳐서 제조한 본원발명의 한식형 그을림 기와는 표면에 고밀도 침탄층이 형성되어져 종래의 그을림 기와에 비하여 압축강도와, 내마모성과, 흡수율이 향상되고 변형이 없는 고품질의 그을림 기와를 제조할 수 있게 된다.In addition, the Korean-style burnt tile of the present invention manufactured by forming the tile with the Korean-style burnt group and the holding composition and undergoing oxidizing and reducing firing is formed with a high-density carburized layer on the surface, so that it has a compressive strength and abrasion resistance. As a result, it is possible to produce high quality sooting tiles with improved water absorption and no deformation.

상기 본 발명으로 제조된 그을림 기와는 종래 방식의 그을림 기와에 비하여 압축 강도, 흡수율, 내마모성을 시험한바 아래와 같이 본원발명의 그을림 기와가 종래의 그을림 기와에 비하여 탁월한 우수성을 확인하였다.The burned roofing tiles prepared according to the present invention were tested for compressive strength, water absorption, and abrasion resistance as compared to the burned roofing tiles of the conventional method, and as described below, the burned roofing tile of the present invention was confirmed to have excellent superiority to the conventional burned roofing tiles.
