Inconel 625 alloy is a super alloy composed of nickel, chromium and molybdenum elements, which has extremely high corrosion resistance and high temperature performance. Due to these properties, Inconel 625 finds widespread use in many industries, including the paper industry.
In the paper production process, various materials and equipment need to have high corrosion resistance and high temperature performance to ensure the quality and production efficiency of the paper produced. Due to its excellent properties, Inconel 625 alloy has been widely used in the paper industry, providing paper companies with a reliable material choice.
This article will introduce the application of Inconel 625 in the paper industry and discuss its advantages and precautions in this field.
First, Inconel 625 has excellent corrosion resistance. This makes it resistant to corrosion by strong acids and alkalis common in the paper industry. Therefore, it is ideal for manufacturing equipment and tools in corrosive environments.
Secondly, Inconel 625 has good wear resistance and high temperature performance, and can still maintain its stability and strength under high temperature and high pressure conditions. This allows it to withstand the high stresses and temperatures of high-speed rotating equipment such as bearings and drums in the paper industry.
In addition, the processability of Inconel 625 is very good. It can be easily processed and assembled. This reduces production costs and processing time and improves production efficiency.
In general, Inconel 625 has broad application prospects and important economic value in the paper industry.
Applications of Inconel 625 in the paper industry:
Paper is made from wood through a series of processes. During this manufacturing process, wood undergoes many physical and chemical treatments. This places very high demands on the performance of papermaking equipment. The following are some typical applications of Inconel 625 in paper production.
Cutting tools and knives:
During the paper production process, wood is debarked, sliced, and shredded. These processes all use cutting tools. When cutting wood, the cutter is not only subjected to high stress but also generates high heat due to friction.
Due to its high hardness, strength and wear resistance, Inconel 625 can be used in the manufacture of cutting tools and knives. Inconel 625 enables these tools to operate at high temperatures with excellent cutting performance and long life.
Steam heater:
The chopped wood is mixed with an acid solution and fed into a steam heater. A steam heater is like a large pressure cooker. It uses high temperatures and pressure to react and mix the wood and acid solution. After a few hours, the wood turned to paste.
The high temperature and high pressure environment in the papermaking process places very high demands on steam heater equipment and pipe materials. Use Inconel 625 to manufacture equipment and pipes that are resistant to high temperatures and pressures. This makes the steam heater resistant to corrosion from high-temperature and high-pressure steam and acidic solutions.
Cleaning and bleaching:
The prepared paste is washed and bleached repeatedly. Washing and bleaching use lots of water and bleach. They all have certain oxidizing or corrosive properties.
Inconel 625 has excellent corrosion resistance and oxidation resistance. Therefore, it can be used to manufacture cleaning and bleaching equipment.
Dehydration equipment:
After bleaching, the paste is dehydrated under the pressure of two rollers. This process also requires materials with excellent oxidation resistance and strength.
Using Inconel 625 to manufacture dewatering drums can ensure their stable operation for a long time. Made of Inconel 625 material can increase its corrosion resistance and high temperature and pressure performance.
Precautions for Inconel 625 in the paper industry:
When using Inconel 625 alloy, you need to pay attention to the following aspects:
First, excessive heating and cooling of the material needs to be avoided. This can lead to oxidation and embrittlement of the material, reducing its performance and service life.
Secondly, when using Inconel 625 alloy to manufacture parts, various parameters during the production process, such as temperature, pressure and atmosphere, need to be strictly controlled. Only in this way can the quality and performance of the final product be guaranteed.
Additionally, solutions and media containing chloride ions should be avoided. This can lead to corrosion and damage to materials, affecting service life and safety.
Finally, when manufacturing parts using Inconel 625 alloy, care should be taken to clean and maintain the material. This prevents impurities and contaminants from damaging the material.
in conclusion:
Inconel 625 is a superalloy widely used in the paper industry. Its excellent corrosion resistance, excellent performance under high temperature and pressure, and good processability make it widely used in the paper industry. It has important applications in cutting tools and knives, steam heaters, bleaching equipment, etc.
However, there are some things you need to pay attention to during use, such as avoiding prolonged exposure to high temperatures and pressure, and avoiding excessive use of coolant.
Overall, the applications of Inconel 625 will continue to be promoted and expanded. It will continue to play an important role in the future paper industry.
