Metallurgical industry as a high temperature, high corrosion, high risk of typical industrial scenarios, the lighting system safety and reliability requirements are extremely stringent.

Molten metal splash, dust explosion risk, strong acid gas corrosion and other problems always threaten production safety, ordinary lighting equipment is not only short life, but also probably due to sparks or high temperature surface triggering major accidents.

Explosion proof fluorescent light 4 foot with its professional explosion-proof design, resistance to extreme environmental characteristics and high luminous efficacy performance, into the metallurgical workshop, foundry and steel furnace area lighting preferred.

In this paper, we will analyze the core value of Explosion proof fluorescent light 4 foot in the metallurgical field, and supply selection, installation and improvement of the whole process of the program.

First, why the metallurgical industry must use Explosion proof fluorescent light 4 foot?

Metallurgical production environment has the following typical risk characteristics:

1. explosive gases and dust: coking process releases hydrogen [H₂], carbon monoxide [CO], aluminum and magnesium alloy processing produces metal dust, are probably to reach the limit of explosive concentration.

2. Extreme high temperature environment: continuous casting workshop temperature often exceeds 50 ℃, ordinary lamps and lanterns are easy due to poor heat dissipation leading to component aging and even fire.

3. chemical corrosion and mechanical shock: pickling process sulfuric acid mist, rolling area metal debris splash, accelerate the damage to the lamps and lanterns and trigger the risk of leakage.

Explosion proof fluorescent light 4 foot are approved for explosion-proof [Ex d] or dust-proof [Ex tD] certification, and use a fully sealed structure and non-combustible materials to ensure that internal arcs and high temperatures are completely isolated from the external hazardous environment.

For example, ceramic insulated terminals are used at both ends of the tube to eliminate the risk of short-circuit caused by molten metal droplets.

Second. Explosion proof fluorescent light 4 foot to deal with metallurgical scenarios core technology breakthroughs

1. Triple protection structure design

Explosion-proof cavity: the lamp shell is made of 316L stainless steel or die-casting aluminum, and the internal explosion pressure is approved to be released from the precision threaded joint surface, which is in line with GB 3836.2 guidelines.

Impact protection: Surface covered with 6mm toughened glass cover, approved for IK10 impact test [20 Joule impact resistance], resisting metal debris splash.

Corrosion-resistant coating: the shell is coated with polytetrafluoroethylene [PTFE] coating to resist sulfuric acid and hydrochloric acid vapor corrosion, extending the service life to more than 5 years.

2. Improved adaptability to high temperature environment

High-efficiency heat dissipation system: built-in annular cooling fins and heat pipe infusion technology, so that the surface temperature of the lamp is always below 85 ℃, to avoid ignition of combustible dust.

Wide temperature driving power supply: It can work in the environment from -40℃ to +120℃, ensuring that the lighting around the steelmaking furnace will not fail due to the sudden change of temperature.

3. Luminous efficiency and energy saving performance upgrade

High-frequency electronic ballast: Eliminate stroboscopic phenomenon, color rendering index [CRI] reaches more than 85, accurately identifying defects on the metal surface and color change of the molten pool.

Intelligent dimming function: approved PLC system linkage, automatically switch to 30% brightness during equipment maintenance, energy saving rate increased by 40%.

Third, metallurgical workshop explosion-proof fluorescent tube selection and installation specifications

Fundamental selection parameter guide

1. Explosion-proof level matching: Coking plant gas area: choose Ex d IIB T4 [gas explosion-proof] or Ex de IIB T4 composite explosion-proof.

2. Aluminum powder processing workshop: give priority to Ex tD A21 IP65 T130℃ [dust explosion-proof].

3. Optical performance requirements: melting furnace operation area: color temperature 5000K cold white light, illuminance ≥ 300 lux; raw materials warehouse: color temperature 4000K neutral light, illuminance ≥ 150 lux.

Fourth, the installation and maintenance of best practices

1. Explosion-proof wiring scheme: armored cable is laid through galvanized steel pipe, and the junction box adopts explosion-proof type and is filled with Ex explosion-proof mastic.

2. Anti-vibration installation design: spring damping brackets are used around the mill and crusher to reduce the risk of lamps falling off due to equipment vibration.

3. Cleaning and maintenance cycle: clean up the metal dust on the surface of the lamp with an anti-static brush every month, and test the elasticity of the sealing ring and the insulation resistance value every quarter.

Fifth. Successful cases: Explosion proof fluorescent light 4 foot in the steel joint venture applications

A large steel group in the steelmaking workshop renovation after the deployment of explosion-proof fluorescent tube system implemented:

Annual lighting-related safety accidents fell to 0, approved ISO 50001 energy management system certification; compared with the original high-pressure sodium lamp system, energy consumption reduced by 55%, maintenance costs reduced by 70%; billet quality inspection accuracy increased by 18%, due to insufficient lighting led to a 12% drop in scrap rate.

Sixth, the future momentum: Explosion proof fluorescent light 4 foot and metallurgical intelligence depth of integration

Along with Industry 4.0 technology in the metallurgical industry penetration, Explosion proof fluorescent light 4 foot are being given more intelligent features:

1. safety warning linkage: integrated infrared sensors to monitor equipment overheating, triggering lights flashing alarm and synchronized shutdown of the power supply in the hazardous area.

2. Energy Efficiency Digital Twin: Approve the built-in meter of the lamps and lanterns to upload energy consumption data in real time, and AI algorithm to improve the workshop lighting strategy.

3. AR-assisted maintenance: Scanning the lamp QR code to retrieve the three-dimensional disassembly guide, shortening the fault repair time by more than 50%.

FAQ: Explosion-proof fluorescent tube in metallurgical industry

Q1: Which is more suitable for metallurgical workshop, explosion-proof fluorescent tube or LED explosion-proof lamp?

A: High-temperature areas [such as around the smelting furnace] preferred Explosion proof fluorescent light 4 foot, because of its heat dissipation uniformity is better than LED, and there is no problem of light decay; low-temperature areas can be combined with LED explosion-proof lamps to enhance energy efficiency.

Q2：Does the high humidity in pickling workshop affect the explosion-proof performance?

A: Explosion proof fluorescent light 4 foot conforming to IP66/IP67 standards can be used for a long time in environments with humidity below 95%, but the sealing of the junction box needs to be checked every month.

Q3：How to deal with the metal slag adhesion on the surface of the lamps and lanterns?

A: Choose the lampshade with nano oleophobic coating, and use high pressure air gun to clean it daily; when serious sintering, you need to stop the machine and use special ceramic spatula to remove it.

Q4: Do I need to replace the ballast regularly for Explosion proof fluorescent light 4 foot?

A: The life span of high quality electronic ballasts can reach 60,000 hours. It is recommended to test the output waveform once every 3 years and replace it quickly if it is abnormal.
