Abstract

본 발명은 고로 노벽 연와 두께를 용이하게 검출하는 방법에 관한 것이다.The present invention relates to a method of easily detecting the furnace wall edge and thickness.

그 기술적인 수단은, 고로의 노내 온도의 변동폭을 설정하고, 변동폭에 따라 열전대 온도의 변화폭을 열전대 온도와 노벽연화 두께와의 상관관계로부터 구하여, 열전대 온도가 변화폭의 범위내내 있으면 노벽의 연와두께가 변하지 않은 것으로 하며, 이 범위를 벗어나면 노내 온도가 최대 및 최소치인 경우의 열전대 온도와 노력연와 두께를 검출하는 것이다.The technical means sets the fluctuation range of the blast furnace furnace temperature and obtains the fluctuation range of the thermocouple temperature according to the fluctuation range from the correlation between the thermocouple temperature and the thickness of the furnace wall softening. If it is out of this range, the thermocouple temperature, hard lead, and thickness at the maximum and minimum temperatures in the furnace are detected.

이에따라, 고로의 노내 온도를 고려하여 노벽의 연와 두께를 정확하게 검출 할 수 있음은 몰론, 이로인한 고로의 수명을 연장시킬수 있는 것이다.Accordingly, the fact that the edge and thickness of the furnace wall can be accurately detected in consideration of the furnace temperature of the blast furnace can extend the lifetime of the blast furnace.

Description

고로 노벽 연와 두께 검출 방법Furnace furnace wall edge thickness detection method

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 고로 노벽연와 및 열전대의 개략 정단면구조도이다.1 is a schematic sectional structural view of the blast furnace furnace wall and thermocouple.

제2도는 고로 노내 온도와 열전대온도의 상관관계를 나타낸 그래프이다.2 is a graph showing the correlation between the furnace temperature and the thermocouple temperature.

제3도(A)(B)는 노벽 두께와 열전대 온도와의 상관관계를 구하는 방법에 관한 설명도이다.3 (A) (B) are explanatory diagrams for a method of obtaining the correlation between the furnace wall thickness and the thermocouple temperature.

제4도는 본 발명에 따른 고로노벽 연와 두께 검출방법을 설명하기 위한 흐름도이다.4 is a flowchart illustrating a blast furnace wall edge thickness detection method according to the present invention.

Claims (1)

노벽내의 여런대 실측온도(Tc)를 측정한후, 노내온도의 변동폭인노내 온도의 최대치(Tcmax)및 최소치(Tcmin)를 설정하여 노내온도가 최대치와 최소치를 가지는 경우에서의 열전대 온도와, 노력연와 두께와의 상관관계를 도출하며, 상기 열전에 온도가 노벽 연화 두께에서 구한 상관관계를 이용하여 열전대 실측온도(Tc)가 노내 온도의 최대치 및 최소치 사이의 값일경우 노벽연와 두께의 변화는 무시하고, 상기 열전대 실측온도 (Tc)가 노내 온도의 최대치 (Tcmax)보다 크게되면 노벽연와 두께를 노내온도가 최대치인 경우의 노벽연와 두께와 열전대 온도와의 상관관계를 이용하여 노벽연와 두께를 산출하고, 열전대 실측온도(Tc)가 노내 온도의 최소치(Tcmin)보다 작으면 노내 온도가 최소치인 경우의 노벽 연와 두께와 열전대 온도와의 상관관계를 통하여 노벽연와 두께를 산출하는 것을 특징으로 하는 고로 노벽 연와 두께 검출방법.After measuring the actual measured temperature (Tc) in the furnace wall, set the maximum value (Tcmax) and minimum value (Tcmin) of the furnace temperature, the fluctuation range of the furnace temperature, and the thermocouple temperature and effort when the furnace temperature has the maximum and minimum values. Deriving the correlation between lead and thickness, and using the correlation obtained from the softening thickness of the furnace wall, if the thermocouple measurement temperature (Tc) is a value between the maximum value and the minimum value of the furnace temperature, the change of the furnace wall thickness and thickness is ignored. When the thermocouple measurement temperature (Tc) is greater than the maximum value (Tcmax) of the furnace temperature, the furnace wall edge and the thickness is calculated by using the correlation between the furnace wall edge and the thickness and the thermocouple temperature when the furnace temperature is the maximum value, If the thermocouple measurement temperature (Tc) is less than the minimum value (Tcmin) of the furnace temperature, the furnace wall edge is correlated with the thickness and the thermocouple temperature when the furnace temperature is minimum. Blast furnace wall kite thickness detecting method, characterized in that for calculating the thickness. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
