Description

연속열처리로의 에너지 절감 시스템 및 제어 방법{Energy saving systems and control methods for continuous heat treatment}Energy saving systems and control methods for continuous heat treatment

본 발명은 연속열처리로에서 버너 운전의 제어와 가스공급제어를 통하여 연속열처리로 운전에 소요되는 에너지를 절감하기 위한 것으로, 상기한 연속열처리로의 영역별로 구비되는 온도센서에 의해 획득되는 온도측정값과 설정된 온도값을 비교하여 버너부의 동작과 가스공급밸브에 제어신호를 전달하되, 연속열처리로의 영역별로 상기 온도센서에 의해 측정되는 온도가 설정온도 이상일 경우에 회귀분석에 의해 에너지절감량을 산출하여, 온도와 분위기가스량에 따른 전력 최적화 조건이 가능하도록 하여 에너지 사용량을 최적화 하도록 하는, 연속열처리로의 에너지 절감 시스템 및 제어방법에 관한 것이다.The present invention is to reduce energy required for operation of a continuous heat treatment furnace through control of burner operation and gas supply control in a continuous heat treatment furnace, and a temperature measurement value obtained by a temperature sensor provided for each area of the continuous heat treatment furnace A control signal is transmitted to the operation of the burner unit and the gas supply valve by comparing the set temperature value with the , It relates to an energy saving system and control method for a continuous heat treatment furnace, which optimizes energy consumption by enabling power optimization conditions according to temperature and atmospheric gas amount.

금속을 소재로 하는 부품은 사용처 및 용도에 따라 기계적 물성을 부여하기 위해 열처리가 필요하고, 이와 같은 열처리를 위한 장비 또는 장치로 열처리로가 활용된다.Parts made of metal require heat treatment to impart mechanical properties depending on the intended use and use, and a heat treatment furnace is used as equipment or apparatus for such heat treatment.

상기한 열처리로에는 전기에 의한 전열방식과 가스에 의한 가스히팅방식으로 구분되며, 열처리로의 특성상 상당한 에너지를 필요로 하게 된다.The heat treatment furnace is divided into a heat transfer method by electricity and a gas heating method by gas, and requires considerable energy due to the nature of the heat treatment furnace.

전기를 이용한 전열방식의 경우, 열선봉을 열처리로에 결합하여 전력공급에 의해 상기 열선봉을 발열시켜 열처리로의 열원으로 사용하고 있다. 이러한 전열방식의 경우 온도 제어가 용이한 장점은 있으나 열선봉의 열처리로 인한 경도부여 내지 고온에 따른 열선 파손 등이 발생되어 유지보수의 어려움과, 사용수명이 짧은 문제점이 있고, 전지를 이용함에 따라 열처리로의 운전비용이 상당히 증가하는 문제점이 있다. In the case of the heat transfer method using electricity, a hot rod is coupled to a heat treatment furnace, and the heat wire is heated by power supply to use it as a heat source for the heat treatment furnace. Although this heat transfer method has the advantage of easy temperature control, it is difficult to maintain and has a short service life because hardness is imparted due to heat treatment of the hot wire or heat wire breakage due to high temperature occurs. There is a problem in that the operating cost of the heat treatment furnace is significantly increased.

이와 달리 가스히팅방식의 열처리로의 경우 전기보다는 비교적 저렴한 비용으로 열처리로의 열원으로 활용되나 온도의 제어가 용이하지 않는 단점이 있다.On the other hand, in the case of a gas heating type heat treatment furnace, it is used as a heat source for a heat treatment furnace at a relatively lower cost than electricity, but has a disadvantage in that temperature control is not easy.

또한, 통상적으로 사용되는 연속열처리로를 이용하여 열처리 공정을 수행할 때, 피열처리체의 열처리는 피열처리체의 이송 방향에 대해서 구획된 복수 가열실과 인접하는 가열실로 피열처리체를 이송하기 위한 이송 수단을 구비한 연속식 열처리로를 사용하고 각 가열실을 개별적으로 온도 제어함으로써, 원하는 온도 곡선에 따라 승온, 균열 지지 및 강온하는 방법으로 수행된다.In addition, when the heat treatment process is performed using a conventionally used continuous heat treatment furnace, the heat treatment of the object to be treated is a transfer for transferring the object to be treated to a plurality of heating chambers partitioned with respect to the transport direction of the object to be treated and a heating chamber adjacent to the heat treatment chamber. It is carried out by using a continuous heat treatment furnace equipped with means and temperature-controlling each heating chamber individually, thereby increasing the temperature, supporting cracks, and lowering the temperature according to a desired temperature curve.

이러한 열처리에 사용되는 연속식 열처리로에 있어서 가열실에 설치되는 가열 수단으로서는 온도 제어의 용이함에서 전기 히터를 이용하는 것이 일반적이지만 최근에는 에너지 절약이나 CO2 배출량의 절감을 목적으로 가스 연소식 래디언트 튜브 버너를 가열 수단으로 하는 시도가 있으나, It is common, but recently, gas combustion Radiant tube for the purpose of reduction of the energy saving and CO 2 emission using an electric heater in the temperature control easy as heating means provided in the heating chamber in a continuous heat treatment used in such a heat treatment Attempts have been made to use a burner as a heating means, but

가스 연소식 래디언트 튜브 버너-를 가열 수단으로 한 연속식 열처리로는 가스 연소식 래디언트 튜브 버너가 통형 발열면을 가지기 때문에, 튜브의 길이 방향에서 정밀한 온도 제어가 수행하지 못하고 피열처리제가 정밀한 온도 분포 정밀도가 요구될 경우에는 사용할 수 있는 범위가 한정되어 충분한 에너지 절약 효과나 CO2 배출량의 절감 효과를 얻을 수 없다.In a continuous heat treatment furnace using a gas-fired radiant tube burner as a heating means, precise temperature control in the longitudinal direction of the tube cannot be performed because the gas-fired radiant tube burner has a cylindrical heating surface. When distribution precision is required, the usable range is limited, so that sufficient energy saving effect or reduction of CO 2 emission cannot be obtained.

본 발명은 연속열처리로(일명 배치식 열처리로)의 에너지 절감 방법을 제시하고자 한다.The present invention intends to propose an energy saving method of a continuous heat treatment furnace (aka batch heat treatment furnace).

본 발명은 통상적으로 알려져 있는 연속열처리로(1)에 적용 가능하며, 연속열처리로의 각 개별열처리로(2) 영역별로 온도센서(10)를 구비하여 각 개별열처리로(2) 내부 온도를 측정하게 된다.The present invention is applicable to a conventionally known continuous heat treatment furnace 1, and a temperature sensor 10 is provided for each individual heat treatment furnace 2 area of the continuous heat treatment furnace to measure the internal temperature of each individual heat treatment furnace 2 will do

한편 상기 연속열처리로(1)의 각 개별열처리로(2)에 각각 적합한 최적의 온도를 미리 온도설정부(20)에 의해 설정되도록 구성하게 되는 온도설정단계(S10)를 거치게 되는데, 각 개별열처리로(2)의 최적 온도는 열처리되는 피열처리체의 특성, 물성 등의 판단 근거에 의해 미리 설정될 수 있다.Meanwhile, a temperature setting step (S10) in which the optimum temperature suitable for each individual heat treatment furnace 2 of the continuous heat treatment furnace 1 is set in advance by the temperature setting unit 20 is passed, and each individual heat treatment The optimum temperature of the furnace 2 may be set in advance based on a judgment basis such as characteristics and physical properties of the object to be heat treated.

이와 같이 각 개별열처리로(2)의 온도설정 후 각 개별열처리로(2)에 구성되어 있는 버너부(51)의 전원 공급에 따라 가스의 초기 공급과 동시에 점화되어 연속열처리로(1)의 가동 상태에 진입하게 되면, 상기한 각 개별열처리로(2)에 구비되는 온도센서(10)에 의해 각 개별열처리로(2)의 실시간 내부 온도를 측정하게 된다.In this way, after the temperature of each individual heat treatment furnace 2 is set, in accordance with the power supply of the burner unit 51 configured in each individual heat treatment furnace 2 , the gas is ignited at the same time as the initial supply of gas, and the continuous heat treatment furnace 1 is operated Upon entering the state, the real-time internal temperature of each individual heat treatment furnace 2 is measured by the temperature sensor 10 provided in each of the individual heat treatment furnaces 2 .

즉, 상기 연속열처리로(1)의 운전에 따라 각 영역별로 구비되는 온도센서를 통하여 온도를 측정하여 획득되는 온도측정값획득단계(S20)를 거치게 된다.That is, according to the operation of the continuous heat treatment furnace 1, a temperature measurement value obtained by measuring the temperature through a temperature sensor provided for each area is obtained (S20).

한편, 온도설정부(20)에 의해 설정된 설정온도값과 각 개별열처리로(2)의 온도센서(10)에 의해 측정된 온도측정값은 작업자의 모니터(60)에 디스플레이되어 실시간 확인 가능하도록 구성하게 된다.On the other hand, the set temperature value set by the temperature setting unit 20 and the temperature measurement value measured by the temperature sensor 10 of each individual heat treatment furnace 2 are displayed on the operator's monitor 60 and configured to be confirmed in real time. will do

아울러, 상기 온도센서(10)에 의해 측정되는 연속열처리로의 각 구역별 개별열처리로(2) 내부 온도측정값은 비교판단부(30)측으로 송신되어, 상기 비교판단부(30)에서 온도설정부(20)에 의해 설정된 설정온도값과 상기 온도센서(10)에 의해 측정된 온도측정값을 비교하게 되는, 온도값비교단계(S30)를 거치게 된다.In addition, the temperature measurement value inside the individual heat treatment furnace 2 for each zone of the continuous heat treatment furnace measured by the temperature sensor 10 is transmitted to the comparison determination unit 30 side, and the temperature is set in the comparison determination unit 30 A temperature value comparison step (S30) of comparing the set temperature value set by the unit 20 and the temperature measurement value measured by the temperature sensor 10 is performed.

온도센서(10)에서 측정되는 온도측정값이, 온도설정부(20)에서 설정된 설정온도값 이상일 경우에는 회귀분석부(40)로 데이터를 송신하여 회귀분석모델을 통해 에너지의 예상 절감량을 산출하게 되는 회귀분석단계(S40)를 거치게 된다.When the temperature measurement value measured by the temperature sensor 10 is greater than or equal to the set temperature value set in the temperature setting unit 20, the data is transmitted to the regression analysis unit 40 to calculate the expected energy savings through the regression analysis model. It goes through a regression analysis step (S40).

이와 같이, 온도값비교단계(S30)를 거쳐 온도측정값이 온도설정부(20)에 의해 설정된 설정온도값 이상일 때 회귀분석부(40)측으로 송신된 데이터값은 회귀분석단계(S40)를 전술한 바와 같이 거쳐, 회귀분석모델에 의해 분석된 결과와, 이로부터 예상 가능한 예상에너지절감량 등이 작업자의 모니터(60)에 디스플레이되는 과정을 거치게 된다.In this way, when the temperature measurement value is greater than or equal to the set temperature value set by the temperature setting unit 20 through the temperature value comparison step (S30), the data value transmitted to the regression analysis unit 40 side is the regression analysis step (S40) above. As described above, the result analyzed by the regression analysis model and the expected energy saving amount that can be predicted therefrom are displayed on the monitor 60 of the operator.

만약, 상기 온도센서(10)에서 측정되는 온도측정값이, 온도설정부(20)에서 설정된 설정온도값 이하일 경우에는 전체적인 열처리로의 효율이 저하될 수 있으므로 해당 영역의 개별열처리로(2) 효율성을 증가시키기 위해, 구역별버너운전제어부(50)를 통하여 해당 개별열처리로(2) 버너부(51)의 운전 및 가스유량제어부(52)제어부(52)에 의해 가스의 공급 유량이 제어되도록 하여, 해당 개별열처리로(2)의 온도가 설정온도값에 근접되도록 제어하게 되는, 가스공급제어단계(S50)를 거치게 된다.If the temperature measurement value measured by the temperature sensor 10 is less than or equal to the set temperature value set by the temperature setting unit 20, the efficiency of the entire heat treatment furnace may decrease, so the efficiency of the individual heat treatment furnace 2 in the corresponding area In order to increase , the operation of the burner unit 51 of the individual heat treatment furnace 2 and the gas supply flow rate are controlled by the gas flow control unit 52 and the control unit 52 through the burner operation control unit 50 for each zone. , a gas supply control step (S50) of controlling the temperature of the individual heat treatment furnace 2 to be close to a set temperature value is performed.
