"One and a half" smelting reduction ironmaking method
One-and-half Step Reduction Process
The One-and-half Step Reduction Process, also known as the Tomiyama Process and the Budden Process, is an innovative, cost effective iron and steel making process that has been used in Japan since the late 1940s. The process involves two key steps that have the......
Hot metal pre-desulfurization
Iron Desulfurization
Iron Desulfurization is an essential process for the production of good iron ore, as the presence of sulfur in iron ore can impart undesirable characteristics to the material. The removal of sulfur from iron ore is necessary in order to purify the ore, eliminate impurities an......
Working principle of infrared carbon and sulfur analyzer
Introduction
Infrared Carbon Sulphur Analyzer (ICSA) is a scientific instrument used in industrial production, which can quickly and accurately measure the amount of carbon, sulphur and other elements contained in powder, liquid and solid samples. This instrument is widely used in industrial prod......
Influence of Supply State Properties of Duplex Stainless Steel on Weldability
Effects of Supply State Characteristics of Duplex Stainless Steel on Weldability
Welding is a process of joining two or more materials by fusing them together. It is a complex process, which includes a wide range of heat treatments, metallography and metallurgical capabilities. The weldability of......
peritectic reaction
Hydrogen embrittlement becomes a serious failure mode of many industrial metallic materials, especially on high-strength steels or alloys that experience high mechanical stress or fatigue, when subjected to high hydrogen content environment. Hydrogen embrittlement of metals is an important phenome......
Forging process of magnesium alloy
ForgeProcessingofMagnesiumAlloy
Magnesium alloys are suitable for die casting, forging and pressing processing, and provide good conditions for energy saving and material utilization. Magnesium alloy has some excellent physical and mechanical properties such as strength, electrical conductivity, ......
Electrometallurgy
Pyrometallurgy
Pyrometallurgy is a key process in the recovery of metals from ores or other sources. It is a branch of metallurgical engineering that involves the use of high temperatures (usually greater than 1000°C) to extract metals and other materials from their ores, either in their solid o......
Utilization of sulfur dioxide in heavy metal smelting flue gas
Utilization of Sulphur Dioxide from the Metallurgical Process Emission
The metallurgical industry is a major contributor to sulfur dioxide (SO2) emissions. The burning of coal combustion, in metallurgical process, can produce a large amount of sulfur dioxide gas. Sulfur dioxide is an air pollutan......
Gold extraction by thiourea method
Cyanidation method is a commonly used gold extraction method for ore containing low content of gold. Generally, leaching is needed to extract gold. Heap leaching technology is suitable for low-grade ore containing gold. The ore is piled up in small heaps and is sprayed with a dilute solution conta......
