Corrosion-Resistant Liner for Food-Grade Extrusion Processes

1.Product Introduction

Linner is usually used inside of the barrrel , near to the screw elements, So its inner wall is easily worn and corroded by materials.

2.New Materials Introduction

Based on long years of experience for the manufacturing, in order to long last the service life of the liner or barrel liner, we developed our special new materials OS02H , a kind of Nickel-Chromium- Tungsten alloy.

Nickel-Chromium- Tungsten alloy has excellent abrasion resistance and corrosion resistance. The increase of Cr content in the nickel-chromium alloy matrix contributes to the oxidation resistance, high temperature resistance and corrosion resistance of the alloy. At the same time, the addition of CrB is better than WC. The microhardness of CrB is as high as 4000-4200DPH, which is close to diamond. It is more conducive to improving the overall strength of the alloy. Due to the high density of WC, it is about 15.7g/cm3, while the matrix of nickel-chromium alloy is only about 8g/cm3. The melting is caused by the uneven surface and depth of the alloy due to the easy segregation of WC, so the content and particle size of WC must be controlled.

Nickel-Chromium-Tungsten alloy( we call OS 02H) hard phase increased to about 50%, OS02 is only ten to thirty,Moreover, the fusion is not sufficient, and the microscopic pores are relatively obvious, which is reflected by the Rockwell hardness HRC of only 52-55.While the Rockwell hardness of nickel chromium tungsten alloy (OS02H) is HRC56-64, the conventional control is HRC58-60. The service life is 3-5 times longer then WR5 or CPM10V.

Nickel-Chromium-Tungsten alloy( OS02H )on the basis of Ni60 in accordance with foreign twin screw working conditions of the formula, greatly improved Hard phase carbides (containing tungsten carbide chromium carbide and other carbides), and the nickel pool fullDissolve. Our Ni-Cr -W alloy layer can reach HRC64 is the best proof.

Main Materials:

NiCrW alloy (Ni60 based on the addition of CrC and CrB)

 

Main Features:

Wear resistance, corrosion resistance, belongs to the special alloy, hardness in HRC≥57, alloy parent full melt, improve the density, hardness.

Material Parameters Temperature Resistance: Temperature limit 600ºC Alloy Layer Thickness: >=1.8mm Alloy Layer Hardness: 57-64HRC

The Main Process Is Different (from the original sintering process to the current spray welding process) The product has better densification, the hardness can reach more than 57 degrees, and the service life of the product is 3-5 times that of the sintering process.

Bimetallic refers to a material or component composed of two different metals or alloys that are bonded together. The purpose of creating a bimetallic structure is to take advantage of the unique properties and characteristics of each metal.

In the context of extruder screws and barrels, bimetallic construction is commonly used to enhance their wear resistance and durability. Typically, the screw or barrel is made of a base material that provides strength and structural integrity, while a wear-resistant alloy is applied to the surface that comes into contact with the material being processed.

The wear-resistant alloy is selected based on its ability to withstand the abrasive and corrosive forces encountered during extrusion. Common materials used for the wear-resistant layer include high-carbon steel, tool steel, tungsten carbide, or other hard alloys. These materials have excellent hardness and resistance to wear, increasing the lifespan of the screw or barrel.

The bimetallic construction allows for the combination of the desirable properties of both materials. The base material provides strength and support, while the wear-resistant alloy protects against abrasion and extends the working life of the extruder screw or barrel.

Overall, bimetallic construction is an effective method to improve the performance and longevity of extruder screws and barrels, reducing downtime and maintenance costs in the extrusion process.

Bimetallic Nickel refers to a type of composite material composed of two layers: a nickel base layer and a second layer consisting of another metal or alloy. The nickel base layer provides the structural integrity and corrosion resistance, while the second layer adds specific properties or functionalities.

Bimetallic Nickel materials are used in various applications where the combination of nickel’s excellent properties with those of another metal or alloy is desirable. This composite material allows for improved performance, durability, and cost-effectiveness compared to using pure nickel or other metals alone.

Some common examples of bimetallic nickel materials include nickel-clad steels, nickel-aluminum composites, and nickel-copper alloys. These materials find applications in industries such as electrical engineering, electronics, automotive, aerospace, and more.

The specific properties imparted by the second layer can vary depending on the intended application. For example, the addition of aluminum can enhance heat dissipation and reduce weight, while copper can improve electrical conductivity. The choice of the second layer material depends on the desired characteristics required for a particular application.

In summary, bimetallic nickel refers to a composite material that combines the properties of nickel with another metal or alloy. It offers enhanced performance and versatility in various industries and applications.
