Explosion proof highaby light: metallurgical industry safety and efficient lighting core to handle the programme

First, Explosion proof highaby light in the metallurgical industry fundamental application scenarios

Metallurgical industry production environment to high temperatures, strong vibration, dust and mixed gases coexist as a feature, for example, ironmaking blast furnace, steel rolling workshop and other areas, conventional lamps and lanterns are prone to structural failure or sparks caused by potential safety hazards.

Explosion proof highaby light with its explosion-proof design, impact resistance and corrosion resistance, into the following core scenarios preferred solution:

1. Ironmaking blast furnace and converter area: the temperature around the furnace body often reaches more than 200 ℃, Explosion proof highaby light adopts aluminium alloy die-casting shell and toughened glass cover, with temperature resistance up to T4 group [≤ 135 ℃], with fins heat dissipation structure, it can be operated stably in the high temperature environment.

2. Raw material conveying and crushing workshop: high concentration of dust, frequent vibration, explosion-proof high bay lamp approved IP66/IP67 protection level sealing design, with impact resistant polycarbonate lampshade [IK10 level], effectively resist dust penetration and mechanical impact.

3. Gas purification and recovery system: gas probably contains CO, H₂ and other flammable gases, explosion-proof high bay lamps in line with the Exd IIB T4 explosion-proof guidelines, explosion-proof cavity can withstand the internal 150kPa explosion pressure, blocking the risk of spark leakage.

4. Underground cable tunnels and emergency access: integrated emergency function Explosion proof highaby light can be automatically activated after a power failure to maintain ≥ 3 hours of lighting to ensure the safe evacuation of personnel and equipment repair 58.

Second, Amasly metallurgical industry choose Explosion proof highaby light five core advantages

1. intrinsic safety and explosion-proof performance Explosion proof highaby light approved explosion-proof structural design, the internal arc and high temperature is completely isolated, to meet the metallurgical industry on the Ⅱ B explosive gas environment protection needs, reduce the probability of lighting equipment triggered by the explosion.

2. Extreme environment and long life temperature range: -40℃ to +80℃, adapt to the metallurgical workshop temperature difference between day and night and local high temperature;

Surface anti-corrosion treatment approved 1000 hours salt spray test, suitable for coastal or chemical subsidiary metallurgical plant;

LED light source life ≥ 60,000 hours, reducing the frequency of overhead maintenance [e.g., 30 metres of the top of the plant lamps and lanterns replacement costs reduced by 70%].

3. energy efficient and cost improvement 200W LED Explosion proof highaby light efficiency of 140 lm / W, compared with the traditional 400W high-pressure sodium lamps, 65% reduction in annual power consumption, a single workshop to save more than ¥ 50,000 in annual electricity. combined with intelligent dimming system, can further reduce energy consumption by 20% -30%.

4. Intelligent control and convenient operation and maintenance with the help of DALI or PLC control system, the implementation of zone dimming, fault alarm and remote monitoring.

For example, the rolling area can automatically adjust the illumination to 500-1000lx according to the production rhythm, taking into account energy efficiency and operational accuracy.

5. Compliance and certification guarantee approval of CNEX explosion-proof certification, ISO9001 quality management system, in line with the ‘Metallurgical Industry Lighting Design Code’ on the mandatory requirements of the hazardous area, to help companies approve the safety acceptance.

Third, Explosion proof highaby light selection technical guidelines

1. Explosion-proof grade: Prefer Exd IIB T4 [for gas, dust environment] or Exd IIC T6 [hydrogen and other high-risk gases];

2. Optical design: asymmetric light distribution [beam angle 120°] is advocated for the steelmaking area, and wide-angle floodlight [150°] is adopted for the raw material yard to improve the coverage uniformity;

3. Material technology: the shell is made of die-casting aluminium alloy + electrostatic spraying, and the light-transmitting cover needs to be equipped with anti-ultraviolet coating to avoid the adhesion of metal dust;

4. Intelligent expansion: optional temperature and humidity sensors or gas concentration monitoring module, linkage lighting system to implement environmental safety warning.

Fourth, application cases: a special steel enterprise steelmaking workshop transformation

A special steel enterprise steelmaking area of the original use of metal halide lamps, the annual failure rate of more than 40%, replaced by AMASLY ALX-GW200 Explosion proof highaby light:

The average illuminance is increased from 150lx to 450lx, which meets the demand of precision operation of steel rolling equipment;

Lamps and lanterns high temperature resistance performance approved 72 hours continuous 200 ℃ environment test, zero failure operation;

Comprehensive annual energy consumption reduced by 58%, the payback period of only 1.8 years.

FAQ: Explosion proof highaby light common problem answers

Q1：Can explosion-proof high bay lamps be used in open-air metallurgical raw materials yard?

Yes, it can be used in open-air metallurgical raw material yard. Explosion-proof high bay lamp IP67 protection grade can withstand heavy rain and dust, and the shell anti-corrosion design is suitable for high humidity environment in the open air.

Q2: How to assess whether the luminaire needs to be upgraded?

If there is light decay >20%, corrosion of the housing or deterioration of the seals, it is recommended to replace the luminaire immediately. Regular testing should be carried out once every 12 months.

Q3: LED Explosion proof highaby light and traditional lamps and lanterns maintenance cost comparison?

200W LED, for example, 10 years of maintenance costs for high-pressure sodium lamps only 1/5, mainly due to long life and low failure rate.

Q4: Does it support customised light distribution scheme?

According to the workshop height and equipment layout design bat wing, symmetrical round and other light distribution mode, improve the uniformity of illumination.
