Composite steel plate ultrasonic flaw detection method GB 7734-87
Ultrasonic testing is a form of non-destructive testing that utilizes the principle of ultrasound, which is the vibration of sound waves greater than the human ear can detect, to detect flaws in a material. It’s one of the most common testing methods used to inspect steel plates, and can be appli......

Steel plate controlled cooling
Using Steel Plate to Control Cooling
One of the most important factors that affects the efficiency of industrial production processes is efficient temperature control. In most cases, this can be done through the use of air conditioning and other cooling systems, but in some specialized applicatio......
New technology of pre-reduction sintering
Introduction
Today, sintering technology has become the mainstream production process of steel production and even the production of many materials. With the rapid development of modern industry, the world has to make great efforts to reduce energy consumption, reduce emissions and reduce produc......
differential analysis
Regression discontinuity design (RDD) is a quasi-experimental design that utilizes a discontinuity or discontinuity in the variables of interest to assess the effects of an intervention. RDD is a method of causal inference used to determine the causal impact of a treatment or intervention. RDD is ......
Cold Crack Tendency of Ferritic Stainless Steel Weld Seam and Fusion Line
Cold Crack Tending of Ferritic Stainless Steel Welds and Fusions
Abstract
This paper discusses the tendency of cold cracking when welding or fusion welding ferritic stainless steel parts together. First, the types of cracking that may occur under these conditions are analyzed, followed by a deta......
Rail Magnetic Particle Inspection Technology
Steel Rail Magnetic Particle Testing Technology
In recent years, the use of steel rail magnetic particle testing (MT) technology has become increasingly popular to complement the dated standard visual inspection and radiography methods used in the metal fabricating industry. Until the 1950’s non......
Metallographic diagram of HT200 steel
The microstructure of HT200 steel is of great importance for its mechanical properties. Microscopic examination of HT200 steel reveals that it is composed of ferrite and pearlite. The presence of pearlite and ferrite is indicative of a hypereutectoid pearlite-ferrite microstructure, also known as ......
