Steel plants are high-risk production environments, where problems caused by dust from different processes create:
Important production delays
An increase in labor costs
Serious health risks for operators.
It is necessary to equip steel plants with powerful vacuum solutions, such as vacuum cleaners from the DHV line. The range is capable of removing large volumes of material efficiently and constantly
SAFE MAINTENANCE AND HOW TO DO IT
Several stages of the production process in the steel plant require constant maintenance, thus avoiding problems that could lead to unexpected production interruptions.
The most important aspects to be monitored are:
CLEANING THE OVERHEAD CRANE
The dust generated by the melting process is deposited on the runways and walkways of the overhead crane that is used to power the electric arc furnace.
The deposited dust leads to major handling problems and short circuits capable of stopping the production.
The ideal solution to recover waste materials in a quick and safe way is a dedicated centralized suction system.
The system consists of metal piping, separator filter, and Delfin high vacuum central suction unit.
Industrial vacuum cleaners with pumps are very powerful solutions, easy to handle thanks to the forklift attachment that makes the disposal of material easier.
The calamine is a heavy material, produced during the cooling of the metal bars. It accumulates in large quantities into the roller mechanisms and under the conveyor lines used to transport the finished product.
In the long run, its presence creates the malfunction of the systems and increases their failures.
The calamine is collected and deposited by the powerful suction units with lobe pumps (by adding a pneumatic conveying system). This allows the system to work efficiently.
The oven is the essential element present in all foundries, the core of production. The dust generated by the casting process constantly accumulates on the top of the oven. These materials are usually removed manually, extending the time when the oven is switched off. The use instead of a suction unit with lobe pumps for constant cleaning allows to:
Cut maintenance time required for cleaning the oven
Ensure the proper heat exchange between the furnace and the surrounding environment
Avoid breakdowns of the furnace handling mechanisms
EXTRACTION FOR THE BLASTING PROCESS
When the raw part comes out of the oven, it is sanded through the blasting process. This process takes place inside dedicated booths where large quantities of small abrasive materials sand and clean the piece.
This leads to a considerable dispersion of often harmful sand in the sand blasting chambers and their removal can be a complex job.
By installing a centralised system with suction inlets near the chambers, it is possible to vacuum and reuse the abrasive material by filtering it from exhausted waste.
THE BENEFITS OF THE DHV RANGE
To prevent future failure, reduce waste of time, and increase the life of the components, continuous and regular maintenance of the system is required. The benefits of using Delfin industrial vacuum solutions are multiple and include:
Reduction of system downtime
Recovery and recycling of materials
Significant reduction in costs and time dedicated to the maintenance
Clean and safe working environments for operators.
DHV vacuum cleaners are equipped with:
High-performance suction unit with self-cooled lobe pumps that guarantee the achievement of very high vacuum and airflow rate values.
A filtering system with different types of filters according to the need. The filter cleaning process can be timed or semi-assisted and is carried out by a counter-cleaning valve of the chambers or with a self-cleaning filter shaker.
A collection unit, consisting of a removable container, can be unloaded from the bottom through a large door or from a lower hopper with a capacity of 1000 lt. The hopper can be unloaded to the bottom through a manually operated butterfly valve. Pneumatic actuators or other types of discharge are also available.
DELFIN DEVELOPMENT AND SUPPORT
Choosing a Delfin vacuum solution, you will have a dedicated team, made up of a technical office and representatives from the " High Vacuum" department.
They will be with you during all phases of the process. From the analysis of the design, installation, and assistance, ensuring full personalization of the system.
