All customerprocesses that use gases - Strategic application technology
Is it possible to imagine a world without steel? No, steel is one of the essential materials in our society and we encounter it every day, whether as a paper clip, means of transportation or skyscrapers. The period of mass steel production began in the mid-19th century with developments from Bessemer, Thomas and Siemens - Martin. The advantage of pure oxygen for refining was already known at that time, but only became technically manageable 100 years later. Steel producers, research institutes and suppliers are working worldwide to improve product properties and manufacturing. Steel is made from iron ore or scrap.
Stone wool production process
Mineral wool, also known as mineral fiber, mineral cotton, man-made mineral fibre (MMMF), and man-made vitreous fiber (MMVF), is a general name for fiber materials that are formed by spinning or drawing molten minerals (or "synthetic minerals" such as slag and ceramics). The nomenclature of these wool products is simply the parent/raw material name in prefix to wool. Wool from glass is glass wool, wool from rock is stone wool and so on. Specific mineral wool products are stone wool and slag wool. Europe also includes glass wool which, together with ceramic fiber, are completely man-made fibers. Applications of mineral wool include thermal insulation, filtration, soundproofing, and hydroponic growth medium.
Typical mineral wool composition
Gases help to produce drinking water of perfect quality. Nowadays, modern treatment facilities largely avoid the use of poisonous or corrosive chemicals. Instead two industrial gases are increasingly used: oxygen and carbon dioxide, both a natural component of the water cycle.
Welding and cutting processes
Aluminum melting process
Just over 50% of aluminum products are produced from recycled secondary aluminum, with the main process steps being scrap conditioning, melting and casting. Depending on the contamination and bulk of the scrap, various types of furnace are used during melting: rotary drum furnaces, chamber furnaces or shaft furnaces. To remove impurities, the aluminum melt is cleaned by gas purging. This takes place in holding furnaces or specially designed ladle stations. In the case of the melt being transported in ladles on vehicles to another processing location, it is necessary to preheat the ladles with burners.
