The science and practice of extracting metals or metal compounds from minerals and transforming them into metallic materials with specific qualities using a variety of processing techniques is known as metallurgy. With the development of technology and the metallurgy industry, the filtration market in this area grows quickly annually.

The need for filtration is increasing and the filter equipment is also developing. In the metallurgy industry, the rolling mill coolant and lubricate system need a filtration system. Equipment coolant and lubricating oil need to be filtered to remove contaminants and accomplish recycling in the metallurgical process in order to save input costs. Filtration can help to extend equipment service life and help equipment stay at optimum level.

Based on their different filtration needs and characteristic, they have respective suitable filtration elements. For the rolling mill coolant system, continuous filtration is crucial, so the automative self-cleaning filter is a great choice for this system.

When it comes to the hydraulic and lubricating system, the most important point is to remove the tiny metal debris and other impurities generated due to thermalization. Depth filter cartridge can be the best choice for this operation, which can effectively eliminate the undesired micro impurities.

Brother Filtration, as a professional and experienced filtration expert, designs and manufactures suitable filter cartridges and filter housings for treatment in metallurgy. If you want to know more about this industry, you can read the introduction for rolling mill coolant and hydraulic & lubricating systems in detail.

Why do we need filtration in the metallurgy industry?

Hydraulic systems are frequently employed in the metallurgical sector. The hydraulic systems are prone to contaminants entering them easily because of the difficult working circumstances they are under.

These contaminants will harm the hydraulic systems and interfere with the proper operation of the metallurgical process if filtering is not done. Air dust filtering is crucial in the metallurgy business because gases produced in the metallurgical process will contaminate the environment if released into the air directly.

What do we need to face in the metallurgy industry?

There are some problems that would be caused by no treatment and filtration, which could result in other losses and a bad working environment.

  • Hydraulic system damage
  • Influencing further steps
  • Low level of productivity
  • Environmental damage

Which process needs filtration in the metallurgy industry?

Coolant filtration

The wear and tear of system parts, pipes, and valves will be accelerated during industrial production by suspended solids, particles, and other pollutants in the fluid, leading to the early collapse of these facilities. Fluid filtration is essential because the impurities in the fluid will unavoidably lower the quality of the finished products.

Backwash filters can efficiently remove solid particles and safeguard important equipment downstream. Additionally, unlike tubular backwash filters achieve automated backwashing by injecting clean water or gas or by employing filtrate inside the filter, wedge wire backwash filters achieve automatic backwashing through filtrate inside the filter housing. Its multi-core or multiple-linked structure minimizes downtime, improves filtration effectiveness, and guarantees continual filtration during backwashing.

Gas-liquid & Liquid-liquid filtration

Oil-water separation or gas-liquid separation is necessary in the metallurgy sector to guarantee that the products are free of contaminants and trace droplets. Therefore, it is crucial to properly consider the hydrophilic or hydrophobic qualities of the filter material as well as its chemical compatibility.

Coalescer separation filters are primarily employed in liquid-liquid separation and gas-liquid separation applications, with the goal of removing further dispersions from liquids or removing trace droplets (water or oil) and solid particles from gases. As a result, it can effectively preserve important equipment downstream while classifying and purifying different media.

Air dust filtration

Nowadays, the energy, non-ferrous metallurgy, and iron and steel industries have all experienced significant growth. As a result, a lot of hot gases containing dust particles are produced during production, and if released into the air directly, they will inevitably harm the environment. Hot gas filtering is therefore crucial for preserving the environment.

Organic fiber dust collection bags are the most popular right now. This style of the dust filter bag is inexpensive and lightweight. However, it is quickly destroyed and has weak resistance to high temperatures. Cake building up on the bag will clog it and make cleaning difficult.

Additionally, filter bags made of ceramic fiber, glass fiber, and other inorganic fibers are available. Ceramic fiber has good resistance to high temperatures and corrosion, but it has poor ductility and is easily brittle when temperatures rise quickly. High-strength glass fiber has subpar folding and wears resistance.
