棒材冷床熱金屬檢測器

在軋鋼生產線上，棒材冷床是整條生產線上的關鍵部分，而熱金屬檢測器（熱檢探頭、紅外線檢測器）又是棒材冷床的重要檢測站，熱金屬檢測器的溫度檢測范圍寬、穩定性好是軋鋼產量和成材率的根本保障。

新一代棒材冷床熱金屬檢測器HMD4、HGE98、HGE65、RJJ4、RJJG型扁口在傳統檢測器的安裝尺寸、接線編號的基礎上進行升級。機芯采用進口元件、檢測頭采用多角度顯微鏡鏡片和大口徑耐高溫工藝玻璃防塵，使檢測范圍更寬。檢測器帶有現場電源變色指示燈、高溫警示燈、實驗按鈕和可靠的航空插頭電線電纜，在現場具有穩定性好，操作維修方便等特點。

1.工作原理

本檢測器接收到鋼的運動信號，經光學部分進行聚焦到光學元件上后經電子線路處理，輸出兩對開關量，繼電器觸點輸出和無觸點電平輸出，實現冷床一個站點的監控。

英文說明：

Hot bl detector

In the rolling steel production line, the cold bed is the key part of the whole production line, and the hot bl detector (thermal detector, infrared detector) is an important inspection station of the cold bed. The wide temperature detection range and the fine stability are the fundamental guarantee of the rolling steel output and yield.

These new generations of hot bl detectors HMD4, HGE98, HGE65, RJJ4, RJJG-flat type are updated from the traditional in aspects of installation dimension and Connection number. Imported components are used in electronic circuits. In the detecting head, the multi-angle microscope lens and the large-diameter heat-resistant dustproof glass are introduced. All these improvements make the detection range wider. The detectors are equipped with color-change indicator, high-temperature warning indicator, test button and reliable aviation plug, electric wires and cables, which have the characteristics of stability, easy-use, easy-maintenance, etc.

1. Working principle

The hot bl detector receives a light signal from the moving steel. The light is concentrated on the optical component. After the signal is processed by electronic circuits, two kinds of switches are outputted: relay passive contact output and contactless active high level output, which implement the monitoring of one station on the cooling bed.

2. Technical beters

— Detected spectral range: 400nm-1100nm

— Detected temperature: 260℃-1400℃

— Response time: contact < 20ms; electric contact < 2ms

— Detected distance: 0.03m-1m

— Working temperature: –25℃－75℃ (air-cooling); –25℃－100℃ (water-cooling)

— Storage temperature: –25℃－70℃

— Power voltage: AC-220V±20％; DC-24V

— Level of protection: IP67

— Self-checking: Press the test button and check if the contact or electric contact is normal.

— Wide-angle lens: microscope lens widening the visual angle of devices

— Photoelectric element: imported VXTB5080 with high sensitiity

— Color-change indicator: green (power supply); red (working)

— Cooling: For water-cooling devices, oxygen hoses can be used as water hoses and several detectors can be concatenated to be cooled together.

— Size: 310mm × 200mm × 56mm (length × height × thickness)

— Weight: 2.10kg

3. How to use

Put the detector in a b where the movement of the hot bl is within the range of detection. Then adjust the direction of the detector to make sure that the hot bl is at the center of detection range. In the end, immobilize the detector.

4. Wiring tables

Wiring table 1 (applicable to HGE98, HGE95, HMD4, RJJ4, RJJG - DC24V)

Wiring table 2 (applicable to HGE65, HGE95, HMD4, RJJ4, RJJG - AC220V)

Note: COM = common point, NO = normally open, NC = normally close.

5. Cautions

① Please do not install the detector in the b radiated by the sunlight directly. Prevent disturbances of sunlight and other possible lights.

② Water-cooling is a must when the environment temperature exceeds 70℃.

③ After a period of usage time, please wipe the dust or dirt on the lens which is hidden in the dustproof cylinder. If the sensitivity is declined, please adjust the sensitivity knob.
