Projecteur ATEX in the metallurgical industry lighting fundamental role and technological breakthroughs

First, Projecteur ATEX in the metallurgical industry core application scenarios

Metallurgical industry covers high-risk areas such as ironmaking blast furnaces, steel rolling workshops, raw material conveyor belts, etc. Its environmental characteristics cover high temperature [200℃+], strong vibration, dust accumulation and combustible gas mixture.

Projecteur ATEX, with their explosion-proof design, corrosion-resistant materials and intelligent temperature control system, have become the first choice for safety lighting in the following scenarios:

1. Ironmaking blast furnace and converter area: the temperature around the furnace often exceeds 200℃, Projecteur ATEX adopts aluminium alloy die-casting shell and toughened glass cover [temperature resistance T4 group ≤135℃], with fin heat dissipation structure, it can be operated stably in high temperature environment.

2. Raw material crushing and conveyor belt: high dust concentration and frequent mechanical vibration, the lamps need to meet the IP66/IP67 protection level and IK10 impact resistance guidelines.

For example, AmaslyATEX LED MAX model is approved with aluminium lamp body and anti-vibration bracket design, which is suitable for long-term vibration environment.

3. gas purification and recovery system: gas contains CO, H₂ and other flammable gases, Projecteur ATEX Exd IIB T4 explosion-proof grade can withstand the internal 150kPa explosion pressure, blocking the risk of arc leakage, in line with the ‘Metallurgical Industry Lighting Design Code’ mandatory requirements.

4. Underground cable tunnels and emergency access: integrated emergency battery model [Amasly ATEX explosion-proof lamps] can maintain ≥ 3 hours of illumination after a power failure, to protect personnel evacuation and equipment repair.

Second, the metallurgical industry choose Projecteur ATEX five technical advantages

1. Intrinsically safe and multiple explosion-proof certificates Projecteur ATEX approved explosion-proof structural design, surface temperature ≤ 80 ℃ [T6 group], to avoid ignition of combustible gases.

For example, Exd IIB T4 certified models can cover 90% of the explosive environment requirements of the metallurgical industry.

2. Energy efficient and intelligent control of LED models with a luminous efficacy of 140 lm / W, 100W lamps and lanterns luminous flux of more than 11,000 lm, compared with the traditional 400W high-pressure sodium lamps, energy consumption is reduced by 65% 415;

Support DALI/0-10V dimming system, according to the production rhythm of automatic adjustment of illumination [such as night time to 50 lx, operating hours to 200 lx], comprehensive energy saving 30%.

3. Extreme environmental adaptability temperature range -40 ℃ to +80 ℃, adapt to the northern cold and southern high temperature climate;

Approved ISO 9227 guidelines 2000 hours salt spray test, the shell using 316L stainless steel or fluorocarbon spray coating process, to resist corrosion of acidic gases.

4. optical improvement and visual safety equipped with asymmetric light distribution [120 ° beam angle] and batwing light pattern, eliminating the ‘black hole effect’, longitudinal brightness uniformity ＞ 0.7, glare index TI <15%, to enhance the accuracy and safety of operations.

5. Long life and low maintenance cost LED light source life ≥ 100,000 hours, reducing the frequency of maintenance at high altitude [such as 20 m high plant maintenance costs reduced by 80%], and modular design to help high-speed replacement parts.

Third, Projecteur ATEX selection and installation specifications

1. Explosion-proof grade: Exd IIB T4 [gas, dust environment] or Exd IIC T6 [hydrogen and other high-risk gases] is preferred. 2;

2. Optical configuration: the raw material area advocates wide-angle floodlight [150 ° coverage], the blast furnace periphery using a concentrated lens centralised lighting;

3. material technology: the shell needs to be die-casting aluminium alloy + anti-static coating, light transmittance > 90%, and with UV protection;

4. Installation guidelines: lamps and lanterns spacing ≤ 8 metres, the height from the ground ≥ 4.5 metres, tilt angle of 5 ° -15 °, to avoid direct line of sight.

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

A rolling workshop original use of halogen floodlights, annual failure rate of more than 50%, replaced with AMASLY ALX-T100 Projecteur ATEX:

Average illuminance increased from 80 lx to 250 lx, rolling accuracy error reduced by 18%;

Lamps approved 2000 hours of salt spray test and -40 ℃ low temperature verification, failure rate down to 3%;

Save ￥320,000 on annual electricity costs, with a payback period of only 1.5 years.

FAQ: ATEX Flood Lights Frequently Asked Questions

Q1：Does Projecteur ATEX need regular explosion-proof testing?

Yes. Every 2 years, you need to carry out explosion-proof surface inspection and sealing test, and submit the explosion-proof certificate to the safety supervision department for record.

Q2: How to deal with metal dust adhesion on the surface of the lamp?

Advocate the use of nano oleophobic coating lampshade, wipe with neutral detergent every month, prohibit the use of strong acid / alkali solution. Some models are equipped with auto-cleaning function.

Q3: What is the energy consumption comparison between LED and halogen Projecteur ATEX?

100W LED model is equivalent to 300W halogen lamp, energy consumption is reduced by 65%, life expectancy is extended by 5 times.

Q4: Can I directly replace the existing high pressure sodium lamp on the circuit?

Need to verify the voltage compatibility [AC220V±15%], advocating the installation of surge protectors and adjust the distribution load.
