Description
Technical Field

Background
Hot metal detector (HMD for short) is photoelectric detection device, and it adopts thermopile sensor as detection device, combines germanium lens imaging principle, discerns the leading edge and the direction of hot metal motion, and then realizes hot metal and detects, and its theory of operation is: the lens transmits infrared thermal radiation emitted by a measured object to the photoelectric conversion circuit to be converted into an electric signal, the electric signal is amplified and then transmitted to the electronic switch comparison circuit, and when the radiation quantity reaches a trigger point, the electronic switch output circuit is triggered. The hot metal detector does not need manual adjustment, can continuously, stably and reliably work in severe environments such as high temperature and the like, and is widely applied to the rolling process of hot rolled strips, building materials and section steel.
The hot metal detector is an important signal source for realizing rolled piece tracking and process automatic control, whether the detection result is accurate or not influences the accurate action of equipment, and if the detection result is inaccurate, rolling waste accidents can be caused. When interference such as smoke dust, water vapor and the like exists between a lens of the hot metal detector and a detected position (such as a roller way) (namely a detection path), the dispersed particles can refract and shield infrared radiation emitted by the hot metal, and the detection accuracy can be greatly reduced.
At present, the following methods are mainly used for solving the technical problems:
(1) and (3) raising the ambient temperature: specifically, a heat source is arranged around the detection area to increase the ambient temperature and reduce the fog. However, increasing the environmental temperature generally causes an increase in energy consumption cost, and there is a method of increasing the environmental temperature by disposing the steel coil just offline near the measurement equipment, but the steam in the environment causes the corrosion of the steel coil surface and is also easy to cause the occurrence of steel mixing accidents.
(2) And the negative pressure dust collecting device is adopted to reduce the environmental dust. However, the negative pressure dust collection mode is adopted, so that the equipment investment is large, the cost is increased, the machine needs to be stopped, and the productivity is reduced.
(3) And a nozzle is additionally arranged on a detection path of the hot metal detector, and dust or mist is swept through compressed air. However, disposal in this manner requires a dedicated dust collection facility, increasing the risk of environmental incidents.
