Through actual production, the punching method and the feeding method are used to produce ductile iron, and the characteristics of the two processes are analyzed. Through the comparison, the comprehensive performance of the castings produced by the feeding method is more stable than that of the punc ...
Since the mid-1980s, in production, some gears generally treated with alloy steel carburizing and quenching process have higher strength requirements, as well as high speed, high power, and high reliability requirements. However, the shape of the steel after carburizing and quenching treatment is re ...
Modern large-scale cold strip rolling mills have realized headless and semi-endless rolling. The requirements for the quality of the strips, such as the surface flatness and thickness difference of the cold-rolled strips, are getting higher and higher, and the quality requirements for the work rolls ...

A few days ago, the first batch of 1,200-ton contract for the easy-weld ultra-high-strength steel Q890CFD independently developed by Baosteel was delivered to users. The product will be used to manufacture super-large hydraulic supports for coal mines. ...
Ultra-low carbon martensitic stainless steel (06Cr13Ni46Mo and 06Cr16Ni46Mo) is an important material usually used for the upper crown, lower ring, blades and guide vanes of important parts of hydraulic turbines. This series of stainless steel materials are difficult in smelting technology and have ...
Continuous casting is a high-efficiency production method. Continuous casting machine is a general term for equipment that continuously completes the segmentation and output of molten steel forming (pouring, condensation). ...
Compared with other high-strength alloy steels with similar chemical composition and processing technology, alloy steel Pyrowear53 has significantly higher strength, plasticity and toughness. In this study, the provided alloy steel bars were sampled from the transverse and longitudinal directions, a ...
For construction machinery, how to better repair faulty construction machinery is an important point. Maintenance is an effective means to restore the technical performance of construction machinery, eliminate faults and eliminate hidden troubles, and extend the service life of machinery ...
