The KR method successfully realized the "three removal" pretreatment of molten iron
Introduction
Hot Metal Desulfurization (HMD) is an important step in ironmaking and steelmaking. To ensure the quality of molten iron, the sulfur content must be controlled in a proper range. HMD is carried out to reduce the sulfur content of the hot metal, so as to meet the requirements of smelt......

The Influence of Different Metallurgical Treatment on
Microstructure and Mechanical Properties of Inconel 783 Alloy
Abstract
Inconel 783 alloy is a high iron-nickel-chromium superalloy developed as an anti-corrosive and wear-resistant material. Different metallurgical processes have different e......
Open hearth
The Carboniferous period is a geological period that occurred approximately 300 million years ago and was characterized by the development of large forests and the intensification of coal deposits. During this period, the Earth experienced extreme climatic changes, with volcanic activity resulting......
Determination of Inclusion Properties by OES Technology in Asea-SKF Process to Study the Influence of Top Dross Composition
Analysis of Impurities Characteristic Using OES Technology in Asea-SKF Process and Its Influence on Dregs Composition
Abstract
In the Asea-SKF process, an optical emission spectrometry (OES) technique is usually used to measure the impurities characteristic and its influence on the dregs compos......
Movement law of oxygen free jet
Introduction
Oxygen atoms are lighter than air and are mainly used in welding because of the energy stored in the bond between two atoms. Due to the light weight of oxygen molecules, when released through a nozzle into the atmosphere, the molecules will travel at high speeds due to their lower ma......
Technical Research on Root Cleaning of Blades Using 4-coordinate CNC Machine Tool (Part 2)
II.Experimental Results
A.The Results of the Design
In the first stage of the experiment, three designs were made: a straight blade, a curved blade, and a shaped blade. The straight blade design had the least amount of surface area. The curved blade had a wider range of surface area, while the s......

With the development of modern technology, advanced plastic forming machines have been applied in many manufacturing processes. Among them, an adaptive electric spark forming machine has become the most popular one, and has been widely......
Comparison of Shear Tests between Ultrasonic Spot Welding and Resistance Spot Welding at Room Temperature
Comparison of Ultrasonic Spot Welding and Resistance Spot Welding Under Room Temperature
Welding is commonly used in many industries, including automotive, aerospace, mechanical, and electrical. It is a permanent joint that bonds together two materials. Ultrasonic spot welding (USW) and resista......
Analysis of the Cracks in the Corresponding Parts of the Shoulder of the Die with Drawbeads Broken
Deep-Joint Tear Analysis of Shoulder Residual Strain Crack in Pullout Mold
Introduction
Deep-joint tear is a crack in the shoulder area of a moulded part that usually occurs when the material between the moulded part and the mould has been pulled apart due to a high force applied during the pull......
Hot metal "one package to the end" test was successful
The successful completion of the one-pack-to-the-bottom experiment of Pellet Iron water proves its superiority in terms of quality and cost. Pellet Iron water is a kind of processed iron ore, which is produced by external heating, smelting and multiplex grinding. It is characterized by low content......
