Horizontal centrifugal casting process of rare earth alloy wear-resistant pipe

Rare earth alloy wear-resistant pipe is produced by horizontal centrifugal casting, in which the smelted liquid metal is passed through the pouring riser and diverted into the rotating mold barrel (the speed of the mold barrel is generally 800-1000 rpm), under the action of centrifugal force A casting method for filling and solidifying into a casting. The horizontal centrifugal casting machine is used for casting various tubular castings and various carbon steel, alloy steel pipes and double-layer steel rolls that require different compositions of inner and outer layers.

Medium carbon alloy rare earth wear-resistant steel

Medium-carbon alloy rare earth wear-resistant steel is a wear-resistant alloy material jointly developed by our factory and North Jiaotong University in the 1980s. After years of continuous improvement, this alloy material has been serialized and can meet various working conditions of power plants.

Power plant boilers have used medium carbon alloy rare earth wear-resistant steel pipe fittings for powder feeding elbows and ash and slag discharge pipes for nearly 20 years, and have won their wide recognition.

Power plants use rare earth wear-resistant pipes for a long time

Medium-carbon alloy rare earth wear-resistant steel materials have the advantages that other wear-resistant materials cannot be used in general, such as accessories for some equipment of power plant coal grinding, pulverizing, ash removal, and slag discharge systems that cannot be manufactured by bimetallic materials. Such as slag scraper scraper, pulverized coal mixer, spiral pipe, etc., can all be made of this material, which brings great convenience to the operation, maintenance and management of the power plant.

The composition design of medium carbon alloy rare earth wear-resistant steel adopts medium carbon multi-alloy system to ensure that the material maintains comprehensive performance indicators. Combining the characteristics of our country’s resources, this material adopts a small amount of multi-element alloy body, and adds FeV, FeNb, Cu and other multi-alloy elements on the basis of the original alloy materials FeCr, FeMn, Ni, Re, FeSi, etc., to ensure the performance of the product.

The medium carbon alloy rare earth wear-resistant steel has high wear resistance, and the rare earth wear-resistant alloy steel has strong wear resistance. After adding FeV, FeNb, and Cu, the metallographic structure of the material has changed. The metallographic structure is: Lath Martensite + Bainite. The grains are finer, the strength is higher, the plasticity is stronger, and the metal matrix is ​​further passivated, so that the wear resistance of the original material has been improved.

Medium carbon alloy rare earth wear-resistant steel has high temperature resistance, strong corrosion resistance and improved wear resistance. The content of Ni and Cr elements in the alloy directly determines the temperature resistance of the material. The content of Cr element and Cu element determines the corrosion resistance of the material. The reasonable combination of these elements makes the new rare earth wear-resistant alloy material have several properties at the same time, such as high wear resistance and high wear resistance. It has excellent corrosion resistance, so it can adapt to the use of various harsh working conditions.

The medium carbon alloy rare earth wear-resistant steel has advanced technology and stable performance. On the basis of centrifugal casting and resin sand molding, our factory has introduced a new EPC lost foam vacuum suction casting process to make molds according to product structure, application, use method, and quantity. High precision, uniform material structure and stable performance, especially for special-shaped parts such as wear-resistant spiral pipes, pulverized coal mixers, fork pipes, import and export hoppers, round and round joints, cone buckets, etc., the wall thickness is uniform.

Installation

Rare earth alloy wear-resistant pipes are suitable for thermal power plants, coal washing plants, coal preparation plants, metallurgical mines and other working conditions in the coal industry. The common connection methods of rare earth alloy wear-resistant pipes include welding, flange connection, and V-connector connection.

Rare earth alloy wear-resistant pipe

Features

Rare earth alloy wear-resistant pipe is used for pneumatic, pumping slurry and other material conveying pipes. It has the characteristics of fast flow rate and large flow rate.

Abrasion resistance

Compared with high manganese steel materials under the same conditions, the unit wear of rare earth alloy is about 1/3 that of high manganese steel, and its service life is 2-3 times that of high manganese steel.

Strong corrosion resistance, high temperature, high wear resistance

Because R alpha composition and structure characteristics of carbide , and the content of solid solution to Cr matrix has strong heat resistance, corrosion resistance, and add the Mo in the high temperature or corrosive environment shows the performance of corrosion resistance, abrasion resistance, add a certain amount of rare earths, giving the inner structure of the alloy is more compact, surface to form a layer of protective film, prevent seepage of carbon. Increased wear resistance, corrosion resistance; Containing a certain amount of boron makes the alloy hardness , which can not was achieved by carburizing. At the same time, containing a certain amount of Mn increases the fatigue resistance of the alloy , so that the wear resistance of the alloy is better than that of high chromium alloy and rare earth alloy.

More convenient installation and maintenance
  • Rare earth wear resistant alloy pipe, metal wear resistant pipe, high hardness, heat treatment pipe arbitrary cutting, unloading, installation, maintenance, very convenient.
  • Elbow and branch pipe can be used together with the seamless steel pipe section, flange connection pipe is more reliable, easy to disassemble.
  • Good welding performance, can be cut, butt-welded with low carbon steel, suitable for operation and construction in various places and environments.

Alloy cast pipe has high pressure resistance

Alloy wear-resistant casting pipe can bear the pressure of 6 ㎏ / cm2, can be applied to gas conveying high pressure pipeline, for external use high-quality steel pipe or is made of high qualified steel plate, hot pressing push system, through the good welding, makes the elbow in more than 10 kg/cm2 pressure is no problem, won’t appear because of local air leakage, diversion phenomenon of material.

Advantages that other wear-resistant materials

Such as bimetallic materials can not be manufactured in the power plant coal grinding, pulverizing, ash removal, slag discharge system of some equipment accessories. Such as dredge scraper, pulverized coal mixer, spiral tube, etc., can be made of this material, which brings great convenience to power plant operation, maintenance and management.

Advanced technology and stable performance

On the basis of centrifugal casting and resin sand molding, the company introduced a new EPC lost foam vacuum suction casting process to make molds according to product structure, application, usage method and quantity, with high dimensional accuracy, uniform material organization and stable performance, especially for wear-resistant Spiral pipes, pulverized coal mixers, fork pipes, import and export hoppers, round and round joints, cone buckets and other special-shaped parts are cast as a whole, and the wall thickness is uniform.

Disadvantages

The disadvantage of rare earth wear-resistant alloy steel is its low impact resistance, so it should be carefully handled during transportation and installation.
