본 발명은 슬래브 보열수단에 관한 것으로, 특히 내부쉘형의 보열커버와, 내부쉘형의 보열커버를 감싸면서 이동가능한 외부쉘형의 보열커버로 이루어져 미활용야드를 없애 슬래브 적재율을 최대화함으로서 가열로내 재로시간을 단축하고 에너지를 절감할 수 있도록 개선된 이중쉘형의 슬래브 보열수단에 관한 것이다. The present invention relates to a slab thermal insulation means, and in particular, consisting of the inner shell-type heat insulation cover and the outer shell-type insulation cover that is movable while covering the inner shell-type heat insulation cover to maximize the slab loading rate by eliminating unused yards, thereby reducing the time for re-heating in the furnace. The present invention relates to a double shell type slab insulation means that can be shortened and energy saved.

도 1은 종래의 슬래브 보열수단의 평면도, 도 2는 그 측면도이다. 도 1 및 도 2의 도시를 참조하면, 종래의 제철소에서 이루어지는 열연, 후판 슬래브는 연속주조공정을 통해 생산되고 있으며, 이러한 슬래브는 기관차의 대차로 이송, 산적되어 열연공장의 가열로로 장입되기 전까지 온도 유지를 위해 보열커버(3)로 덮어 보관하도록 되어 있다. 즉, 슬래브 야드에서 보열커버(3)로 슬래브(4)를 보온하여 가열로에 장입함으로서 가열로내 재로시간을 단축하고 에너지를 절감하기 위함이다. 이러한 보열커버(3)는 슬래브를 덮을 수 있도록 하단이 개구된 함체의 형태를 가지며, 그 내측면에는 단열재가 부착된 구조로 이루어진다. 1 is a plan view of a conventional slab heat insulating means, Figure 2 is a side view thereof. Referring to FIGS. 1 and 2, hot rolled and thick plate slabs made in a conventional steel mill are produced through a continuous casting process, and these slabs are transferred to a bogie of a locomotive and stacked before being charged into a heating furnace of a hot rolling mill. In order to maintain the temperature is covered with a heat cover (3). In other words, the slab yard to keep the slab (4) to the heat retaining cover (3) to charge the heating furnace in order to shorten the re-heating time in the furnace and save energy. The heat cover 3 has a form of a housing having a lower end opening so as to cover the slab, and an inner surface of the heat insulating cover 3 is attached to the heat insulating cover 3.

그런데, 이와 같은 보열커버(3)로 슬래브를 덮은후에 크레인(1)으로 슬래 브(4)를 이송하기 위하여 적재 혹은 인출하고자 하는 경우에는 슬래브(4)를 덮고 있는 위치의 보열커버(3)를 옆으로 이동시키기 위해 대기공간을 필요로 하며, 이러한 대기공간 만큼 필연적으로 슬래브 비활용야드 지역(5)이 발생하게 되어 슬래브 적재율이 낮아지는 문제점이 있었다. 이로 인해 가열로내 재로시간이 장기화되고, 에너지의 낭비로 생산성과 제품의 단가가 상승되는 문제로 이어지므로 그 개선책이 요구되고 있는 실정이었다.By the way, when the slab is covered with the heat retaining cover 3, the heat retaining cover 3 at the position covering the slab 4 is to be loaded or withdrawn in order to transport the slab 4 to the crane 1. It requires a waiting space to move sideways, the slab inutilization yard area (5) inevitably occurs as much as this waiting space has a problem that the slab loading rate is lowered. This has led to the problem of prolonged working hours in the furnace and the increase in productivity and the cost of products due to waste of energy.

본 발명은 상술한 바와 같은 종래 기술의 제반 문제점을 해소하고자 안출된 것으로, 슬래브 적재율이 최대화되어 가열로내 재로시간이 단축되고 에너지 절감효과를 얻을 수 있도록 내부쉘형의 보열커버와, 내부쉘형의 보열커버를 감싸면서 이동가능한 외부쉘형의 보열커버로 이루어지는 이중쉘형의 슬래브 보열수단을 제공하는 것을 목적으로 하는 것이다. The present invention has been made to solve all the problems of the prior art as described above, the inner shell type heat insulation cover and the inner shell heat insulation to maximize the slab loading rate to shorten the time in the furnace and energy saving effect An object of the present invention is to provide a double shell type slab heat insulating means comprising a heat insulating cover of an outer shell type that is movable while covering a cover.

상기 과제를 해결하기 위한 본 발명의 이중쉘형 슬래브 보열수단은 슬래브 보열을 위한 다수의 보열커버들이 레일상에 구비되어 이루어지는 보열수단에 있어서, 상기 보열수단은 상기 다수의 보열커버들을 감싸면서 이동 가능하도록 된 외부쉘형의 보열커버를 적어도 하나 이상 포함하여 구성되어진 것을 특징으로 한다. The double-shell slab heat insulating means of the present invention for solving the above problems is a heat holding means is provided with a plurality of heat retaining cover for the slab heat retaining on the rail, the heat retaining means to be movable while wrapping the plurality of heat retaining covers Characterized in that it is configured to include at least one of the outer shell type heat insulating cover.

이때, 상기 이중쉘형 슬래브 보열수단은 상기 레일보다 넓은 폭으로 이루어진 제2레일이 구비되고, 상기 외부쉘형의 보열커버는 상기 제2레일을 따라 이동하 도록 구성되어진 것을 특징으로 한다. At this time, the double shell-type slab insulation means is provided with a second rail having a wider width than the rail, the outer shell-type heat insulation cover is characterized in that configured to move along the second rail.

본 발명의 이중쉘형 슬래브 보열수단에 의하면, 인출하고자 하는 슬래브를 보열하고 있던 보열커버를 이동시키도록 마련된 대기공간인 비활용야드를 필요로 하지 않으며, 다른 보열커버를 감싸도록 외부쉘형의 보열커버를 이동시키면 되므로, 슬래브 보열을 위한 야드의 활용율을 극대화할 수 있으며, 이로 인해 슬래브 보열의 효율성을 향상시켜 가열로 재로시간을 단축함은 물론, 제품 생산성 제고로 제조 단가를 낮출 수 있다.According to the double-shell slab heat insulating means of the present invention, the outer shell heat retaining cover is not required to cover the other heat cover without requiring a non-utilization yard, which is an air space provided to move the heat retaining cover which holds the slab to be pulled out. Since it is possible to move, it is possible to maximize the utilization rate of the yard for slab insulation, thereby improving the efficiency of slab insulation to shorten the time of reheating furnace, as well as to lower the manufacturing cost by improving product productivity.

이하, 첨부된 도면을 참조하여 본 발명에 따른 이중쉘형 슬래브 보열수단을 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail the double shell type slab heat insulating means according to the present invention.

도 3은 본 발명의 이중쉘형 슬래브 보열수단의 평면도, 도 4는 본 발명의 이중쉘형 슬래브 보열수단의 측면도이다. Figure 3 is a plan view of a double shell type slab heat insulating means of the present invention, Figure 4 is a side view of a double shell type slab heat insulating means of the present invention.

도 3 및 도 4를 참조하여 설명하면, 본 발명에 따른 이중쉘형 슬래브 보열수단은 슬래브 보열을 위한 다수의 보열커버들이 레일상에 구비되어 이루어짐은 종래의 보열수단과 동일하나, 상기 다수의 보열커버(3)들을 감싸면서 이동 가능하도록 된 외부쉘형의 보열커버(8)를 적어도 하나 이상 포함하여 구성되어진다. Referring to Figures 3 and 4, the double shell type slab thermal insulation means according to the present invention is provided with a plurality of heat retaining cover on the rail for the slab heat retaining is the same as the conventional heat retaining means, the plurality of heat retaining cover (3) is configured to include at least one of the outer shell type heat insulating cover 8 to be movable while wrapping.

상기 이중쉘형 슬래브 보열수단은 슬래브 야드에 슬래브(4)의 길이방향으로 다수의 보열커버(3)들이 이동 가능한 레일(12)과 함께, 상기 레일보다 넓은 폭으로 이루어진 제2레일(10)이 구비되며, 상기 외부쉘형의 보열커버(8)는 상기 제2레 일(10)을 따라 이동 가능하다.The double shell type slab insulation means is provided with a second rail (10) having a wider width than the rail, along with a rail (12) movable a plurality of heat retaining cover (3) in the longitudinal direction of the slab (4) on the slab yard. The outer shell thermal insulation cover 8 is movable along the second rail 10.

이하, 상기 외부쉘형의 보열커버(8)보다 작은 크기로 이루어지는 다수의 보열커버(3)들은 내부쉘형의 보열커버(3)로 칭하여 설명하기로 한다. Hereinafter, the plurality of heat retaining covers 3 having a smaller size than the outer shell heat retaining cover 8 will be described as an inner shell heat retaining cover 3.

외부쉘형의 보열커버(8)는 이와 인접하는 내부쉘형의 보열커버(3)보다 큰 폭과 높이를 가지므로 제2레일을 따라 이동하더라도 내부쉘형의 보열커버(3)와 충돌하지 않고 이를 감싸면서 이중쉘형의 슬래브 보열구조를 형성하는 것이다.Since the outer shell heat retaining cover 8 has a width and a height greater than that of the inner shell heat retaining cover 3 adjacent thereto, the outer shell heat retaining cover 8 does not collide with the inner shell heat retaining cover 3 even when moving along the second rail. It is to form a double shell type slab thermal insulation structure.

다만, 외부쉘형의 보열커버(8)는 내부쉘형의 보열커버(3)를 감싸면서 이동가능한 한도내에서 그 크기를 최소화하여 공간의 활용성을 높이고 제작 단가를 낮추도록 함이 바람직하다. However, the outer shell heat retaining cover 8 is preferably to minimize the size of the inner shell heat retaining cover (3) within the movable limit to increase the utilization of space and lower the manufacturing cost.

외부쉘형의 보열커버(8)는 내부쉘형의 보열커버(3)와 크기에 있어서는 상이하나, 그 구조와 작동방식은 동일하게 이루어질 수 있다. The outer shell heat retaining cover 8 is different in size from the inner shell heat retaining cover 3, but the structure and operation thereof may be the same.

즉, 외부쉘형 보열커버(8)는 내부쉘형의 보열커버(3)와 동일하게 하부가 개방된 함체의 형태를 가지며, 내측면에는 단열재가 부착된 구조로 이루어질 수 있다. 또한, 내부쉘형의 보열커버(3)의 구동방식과 동일하게 전동식이나 유압식과 같은 구동방식으로 제2레일 상으로 이동되어질 수 있다. That is, the outer shell heat retaining cover 8 may have a shape of an enclosure having a lower opening like the inner shell heat retaining cover 3, and a heat insulating material attached to an inner surface thereof. In addition, it can be moved on the second rail by a driving method such as an electric or hydraulic type in the same manner as the driving method of the inner shell type thermal cover 3.

이하에서는 상기의 구조로 이루어진 본 발명에 따른 이중쉘형 슬래브 보열수단에 의해 수행되어지는 슬래브 보열과정을 설명한다. Hereinafter will be described the slab insulation process performed by the double-shell slab insulation means according to the present invention having the above structure.

우선, 슬래브를 적재하고자 하는 야드(5)에 대기하고 있던 외부쉘형 보열커버(8)를 제2레일(10)을 따라 이동시킨다. 이때 외부쉘형 보열커버(8)는 인접된 내 부쉘형 보열커버(3)와 충돌되는 일 없이 감싸면서 이동되어 내부쉘형 보열커버(3)의 외부에 외부쉘형 보열커버(8)가 구비된 이중쉘형 슬래브 보열구조를 이룬 상태로 대기한다.First, the outer shell heat retaining cover 8 that has been waiting in the yard 5 to load the slab is moved along the second rail 10. At this time, the outer shell heat retaining cover 8 is moved while wrapping without colliding with the adjacent inner shell heat retaining cover 3, and the double shell type having the outer shell heat retaining cover 8 on the outside of the inner shell heat retaining cover 3. Wait for the slab insulation structure.

다음으로, 크레인으로 슬래브를 야드(5)에 내려 놓게 되면, 측면으로 빠져있던 외부쉘형 보열커버를 다시 슬래브가 적재된 야드(Yard)으로 이동시켜, 슬래브를 보열한다. Next, when the slab is lowered to the yard 5 by a crane, the outer shell-type heat retaining cover that has been dropped to the side is moved back to the yard where the slab is loaded and heats the slab.

또한, 도 5의 (a)의 도시와 같이 슬래브(4)를 외부쉘형 보열커버(3)로 덮은 상태에서, 슬래브(4)를 추출하고자 하는 경우, 도 5의 (b)의 도시와 같이, 외부쉘형 보열커버(8)를 인접 내부쉘형 보열커버(3)를 감싸도록 이동시킨후, 크레인으로 야드(5)에 적치된 슬래브(4)를 인출하며, 슬래브 인출이 완료되면 도 5의 (c)의 도시와 같이 다시 외부쉘형 보열커버(8)를 야드(5)에 원위치시키는 순으로 수행한다. In addition, when the slab 4 is to be extracted in a state in which the slab 4 is covered with the outer shell thermal insulation cover 3 as shown in FIG. 5A, as shown in FIG. 5B, After moving the outer shell type heat retaining cover 8 to surround the adjacent inner shell type heat retaining cover 3, the slab 4 loaded on the yard 5 is drawn out by a crane, and when the withdrawal of the slab is completed, FIG. As shown in Fig. 1), the outer shell heat retaining cover 8 is again placed in the yard 5.

따라서, 기존의 경우 슬래브 인출이나 적출시 보열커버를 대기시키기 위하여 불가피하게 존재할 수 밖에 없었던 비활용야드(5)로 인해 야드 활용율에 제한이 따랐으나, 본 발명에 따르면 외부쉘형 보열커버(8)를 인접하는 내부쉘형 보열커버(3)측으로 충돌 없이 이동시키는 이중쉘형의 슬래브 보열구조를 가지므로, 비활용야드(5)를 없애고 슬래브 야드의 적재율을 최대화하여 활용할 수 있어 생산성을 향상시키게 되는 것이다.Therefore, the conventional yard utilization rate was limited due to the inactive yard (5) inevitably existed to wait for the heat cover when the slab withdrawal or extraction, in accordance with the present invention, the outer shell type heat cover (8) Since it has a double-shell slab thermal insulation structure to move to the adjacent inner shell-type heat insulation cover 3 without collision, it is possible to eliminate the inactive yard (5) and to maximize the loading rate of the slab yard to improve productivity.
