Application in Steel Industry
A Spray Nozzle may have a multitude of applications in a wide variety of industries, however they serve certain purposes that are vital in the process of manufacturing steel, for instance,
- Slab, Bloom & Billet cooling.
- Cooling of Rolls.
- Rinsing & cooling of pickling lines.
- Spray systems used in Dust Control Systems (DCS).
Characteristics
It is important for the Spray Nozzle to be manufactured with certain characteristics that fit applicable environments, therefore, regarding their use in Steel Mills, they should ideally have the following characteristics.
- Produce a cone spray pattern for optimal cooling, washing & dust control.
- Even distribution of spray pattern.
- Designated spray angles for specific purposes.
Types of Materials
Spray nozzles are manufactured in a wide variety of materials. Depending on the type of material used, their resistance to factors such as Heat and Chemicals vary greatly, hence it is imperative to understand the properties of these materials to ensure the efficiency and prolonged lifespan of the spray nozzles.
Stainless Steel
Stainless Steel Spray Nozzles are used widely throughout many industries due to their resistance to heat. They are able to withstand temperatures up to 800°C but perform poorly against certain chemicals making them less resistant to corrosion.
Brass
Made from copper and zinc alloys, Brass Spray Nozzle are a less expensive yet excellent replacement for stainless steel spray nozzles. They have a high resistance to corrosion making them extremely durable, which is increased when paired with protective coating.
Aluminum
Due to its low density, Aluminum Spray Nozzles do not have much use in Industrial Machinery, rather they are used in lawn and turf applications where the use of soft metals is acceptable.
Ceramic
Ceramic Spray nozzles offer a high degree of resistance to wear and chemicals making them a good candidate against abrasions and corrosions.
Spray Nozzle for Steel Making
When selecting equipment or consumable for any industrial process, it is vital to be aware of the conditions the equipment might go through. During the Steel manufacturing process, there are various stages to be considered where the equipment goes through high temperatures, exposure to various chemicals and abrasions. Keeping these factors in mind, Brass Spray Nozzles prove to be the ideal candidate to ensure longevity and reliable use.
Brass vs Steel - Which Spray Nozzle is better?
As discussed previously, Steel and Brass Spray Nozzles both offer a great degree of protection against high temperatures and abrasions, but Brass Spray Nozzles offer additional advantages of resistance against corrosion and cause less noise pollution. This means that they are more reliable while exposed to chemicals while also being a more economical option than Steel Spray Nozzles. Hence, keeping the following factors in mind;
- Resistance against abrasions.
- Resistance against corrosions.
- Reliable under high temperatures.
- More economical than other materials.
- Cause less noise pollution.
Brass Spray Nozzles prove to be the best option for the process of Steel making i.e. cooling of Slab, Billets, Blooms, Rolls, rinsing and cooling of pickling lines and for use in Dust Control Systems (DCS).
