棒材冷床热金属检测器
在轧钢生产线上，棒材冷床是整条生产线上的关键部分，而热金属检测器（热检探头、红外线检测器）又是棒材冷床的重要检测站，热金属检测器的温度检测范围宽、稳定性好是轧钢产量和成材率的根本保障。
新一代棒材冷床热金属检测器 HMD1型、LTD1型、RJJ1型在传统检测器的安装尺寸、接线编号的基础上进行升级。机芯采用进口元件、检测头采用多角度显微镜镜片和大口径耐高温工艺玻璃防尘，使检测范围更宽。检测器带有现场电源变色指示灯、高温警示灯、实验按钮和可靠的航空插头电线电缆，在现场具有稳定性好，操作维修方便等特点。

英文说明：
Hot metal detector
In the rolling steel production line, the cold bed is the key part of the whole production line, and the hot metal 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 metal detectors HMD1, LTD1, RJJ1-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 metal 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 parameters
— 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: 420mm × 230mm × 85mm (length × height × thickness)
— Weight: 3.91kg
3. How to use
Put the detector in a position where the movement of the hot metal is within the range of detection. Then adjust the direction of the detector to make sure that the hot metal is at the center of detection range. In the end, immobilize the detector.
4. Wiring tables
Wiring table 1 (applicable to HMD1, LTD1, RJJ1 - DC24V type)
Pin number | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
Color | brown (positive) | red | orange (pink) | yellow | green | blue | purple (white) |
Function | DC24V input | NO | COM | NC | high level (+24V) | low level (0V) | |
passive contact output (relay) | active electric contact output | ||||||
Wiring table 2 (applicable to HMD1, LTD1, RJJ1 - AC220V type)
Pin number | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
Color | brown | red | orange (pink) | yellow | green | blue | purple (white) |
Function | AC220V input | NO | COM | NC | NO | ||
passive contact output (relay) | electric contact output | ||||||
Note: COM = common point, NO = normally open, NC = normally close.
5. Cautions
① Please do not install the detector in the position 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.
