Common Detection Methods of High Speed Steel Roll

Common Detection Methods of High Speed Steel Roll

High-speed steel rolls have good wear resistance and thermal crack resistance, but they are sensitive to cracks caused by cooling, improper use or mechanical damage. Surface crack is the main reason of high speed steel roll failure. Generally, the surface of high-speed steel rolls is prone to mechanical cracks, network "hot" cracks, stress cracks and fatigue cracks. All manufacturers generally adopt good non-destructive testing methods and procedures to regularly inspect the rolls, and repair and replace the high-speed steel rolls with problems in advance to avoid rolling accidents. So, let's take a look at the common detection methods of high speed steel rolls. Commonly used high-speed steel roll detection methods are: 1. eddy current automatic flaw detection advantages: belonging to automatic flaw detection, with automatic recording system, can accurately determine the axial position of defects on the roll. The detection sensitivity is high, and some small surface or near surface defects can be found, which is unmatched by other detection methods such as ultrasonic. Disadvantages: The type, shape and depth of the crack cannot be determined, and the true equivalent of the defect cannot be determined. Sometimes it is affected by many factors, such as the distance between the probe coil and the measured reel, the material, size, shape, conductivity, magnetic permeability, defect type, etc. of the reel. Periodic calibration of eddy current sensitivity and other flaw detection

Characteristics and using process of high speed steel roll

Characteristics and using process of high speed steel roll

High-speed steel roll is a hot-rolled material with rapid development and wide application in recent years. Its composition is more complex alloy steel. Can harden. The working layer is made of high carbon steel, and the roller core is made of ductile iron, graphite steel or forged steel. The two different materials are compounded by centrifugal casting or CPC process. The matrix structure is generally tempered martensite bainite carbide, and the carbide is distributed in the matrix in a highly dispersed form, so it has high wear resistance and toughness, which makes turning difficult. So, let's take a look at the characteristics and use of high-speed steel rolls. High-speed steel roll features: good thermal stability, good hardenability, high carbide hardness, easy to form oxide film, thermal cracking resistance and good wear resistance, the requirements for cooling water is far lower than that of cemented carbide. Requirements, its single groove rolling capacity can reach 45 times the cast iron roll. It is beneficial to the negative tolerance control of the rolled material and improve the surface quality of the rolled material. It is mainly aimed at the application of online bar products and finished front frames, as well as the development of new material coils for slitting and rolling pre-cutting and slitting passes. The hardness can reach HSD78-90, high wear resistance, good impact resistance and good thermal fatigue resistance. With the popularity of high-speed steel roll online bar mill, R & D manufacturers quickly spread out. But the manufacturers in high

Advantages of high speed steel roll

Advantages of high speed steel roll

High-speed steel roll is a high-carbon high-speed steel composite roll, which has become an important part of the development of modern rolling production. After 20 years of development, it has been widely used in rolling mills all over the world. At present, cast high-speed steel rolls are not only widely used in the finishing stands of cold and hot strip steel hot rolling mills, but also in the finishing stands of wire and bar mills. Is a very good application, then, let's take a look at the advantages of high speed steel roll. The advantages of high-speed steel rolls: 1. High hardness of carbides: The rolls used in the past mostly distribute Fe3C or M7C3 eutectic carbides on the matrix, with coarse organization and low hardness. High-speed steel rolls generally use high-C, high-V high-speed steel, but also contain more Cr, Mo, W, Nb, Co and other alloying elements. During solidification and heat treatment, these alloying elements form primary and secondary carbides. Things. High chromium cast iron roll carbide M7C3(2500Hv) and M23C6(1600Hv). In the infinite chilled cast iron roll, the carbide is Fe3C(l300Hv). 2, good thermal stability: high speed steel roll contains more W, Cr, Mo, V, Nb and other elements, good thermal stability. The study found that the hardness of ordinary roll material with temperature
