Product Description

NP1313 Blow Bar High Chrome Casting Wear Parts Hammer Plate For Impact Crusher Mining Machine
Product Description
Hyton produces High Chrome casting liners mainly include Blow bar,hammer plate ,hammer head ,impact plate and etc, High Chromeparts are available from 15% to 26% High alloys.
With chromium steel, the carbon is chemically bonded in the form of chromium carbide. The wear resistance of chrome steel is based on these hard carbides of the hard matrix, whereby the movement is hindered by offsets, which provides for a high degree of strength but at the same time less toughness.

1.Material : High chrome, ceramic insert and customised material.
2.Usage : Wear parts for crusher in the quarry, mining, aggregate, recycling,demolition field etc.
3.Production quality testing : Hardness testing, metallographic testing, spectral analysis, mechanical properties and heat treatment.
4.Competitive feature : High quality with moderate price.
5.Production base : Has a core production base in Jiangsu Province, and cooperates with brother foundries. We have established a "production and supply alliance organization" with many brother foundries.
6.We have rich experience and qualifications in the production of alloy steel, manganese, ductile iron, high chromium cast iron and ceramic insert and titanium carbide & tungsten carbide insert technology.
7.We are able to supply the most cost-effective solutions and ways of working for our customers with different needs.

Impact Crusher Wear PartsFeatures.

Permanganese steel has good toughness, at the same time under strong impact and large pressure, will produce processing hardening, thereby improving the resistance of permanganese steel Grinding. With the development of railway, metallurgy, mining and other industries, the performance of wear-resistant materials put forward higher requirements, at the same time the need for wear-resistant materials The increasing demand provides impetus for the development of wear-resistant materials. However, under certain operating conditions, the wear resistance of permanganese steel is not high.

Permanganese steel substrate tissue

Figure 1 is a permanganese steel substrate tissue, as can be seen from Figure 1a: Under the new heat treatment, there is no precipitation along the crystal carbide. As can be seen from Figure 2b: Raw heat treatment
Under, carbide not only precipitates along the crystal, but also has a large number of carbides in the crystal. Between 400 and 550 degrees C is the temperature zone where carbides are precipitated and grown.
In between, the primary heat treatment process in this temperature range insulation 1 h, so that a large number of carbides precipitated.

Different heat treatment process substrate impact breaks

Figure 2a is a broken shape with a impact toughness value of 190 J/cm2, as can be seen from Figure 2a: "Under the new heat treatment process, there are a large number of ligaments in the impact break profile, which is the reason for the high impact toughness value." Figure 2b is a broken profile with an impact toughness value of 84 J/cm2, from Figure 2b
It can be seen that: under the raw heat treatment process, the severed shape is the quasi-dissociation of the severed shape, so the impact toughness value is lower.
Substrate carbide

Figure 3 is the analysis of carbon diffusion in the crystal under the new process. As can be seen from the results: dot block precipitated carbide as Fe, Cr, Mn compound carbide. This carbide, dispersed on the substrate, enhances the base's ability to resist abrasive wear. Carbonization began to precipitate in Auschwitz
The temperature of the material is 125 degrees C, but at this temperature the amount of carbide is very small, in order to
increase the amount of carbide in the dispersion of the substrate, need Increase the aging temperature, but more than 450 degrees C carbide will appear crystal boundary continuous mesh distribution, there will also be large carbide inside the crystal; New heat treatment
The process is time-sensitive at 350 degrees C, which maintains the high toughness of the substrate while improving the wear resistance of the substrate.

The combination of ceramic blocks and per manganese steel substrates and mechanism
The combination of ceramic blocks and substrates affects the life of the material. The interface of the material is analyzed in the gold phase.
The binding of ceramic blocks to permanganese steel is observed through a scanning electron mirror, as shown in Figure 4. Figure 4a High manganese steel and ceramic blocks under the new process.
The combination is good, and the substrate close to the ceramic block is free of micro-cracks. The per manganese steel substrate tissue close to the ceramic block is fine, and the carbide dispersion is distributed. Figure 4b Under the old process, the combination of permanganese steel and ceramic blocks is poor, and the substrate close to the ceramic block has micro-cracks. The per manganese steel substrate is large in tissue and carbon.
Dispersion distribution of chemicals to reduce binding strength; As can be seen from Figure 4c: The ceramic and substrate of the binding site are interlaced, and ceramic particles and substrates can be seen in the body is embedded in the permanganese steel substrate.

To better examine the binding status of the combined material interface, Figure 5 shows the EDS line scan photo at the junction, from Figure 5 It can be seen that: metal ceramics and permanganese steel substrates combine very well, and permanganese steel and metal ceramic substrates melt into one. Fe element of the substrate material Content, from substrate to metal ceramics, in the interface showed a decreasing trend; The content of Ti elements, from metal ceramics to substrates, decreases significantly, and the Ti content at the interface is lower than that of metal ceramics far from the interface the Ti content, but the diffusion distance of the Ti element Shorter. The diffusion of these two elements is thermal diffusion Results.
The heat of the metal solution of the permanganese steel substrate makes pottery Porcelain blocks are placed for quite some time after pouring at high temperatures, and the effect of temperature on the speed of diffusion shows Exponential changes, which greatly increases the diffusion rate High, the formation of a better metallurgical combination.
