Ferrosilicon is used as a source of silicon to reduce metals from their oxides and to deoxidize steel and other ferrous alloys. This prevents the loss of carbon from the molten steel (so called blocking the heat); ferromanganese, spiegeleisen, calcium silicides, and many other materials are used for the same purpose. [5]
The whole factory was destroyed making a crater with a depth about 7 m (23 ft) and a diameter of 40 m (131 ft); [1] steel girders were found 3 km away from the explosion. The blast measured 3.4 on the Richter scale, [2] with an estimated power equivalent to 20-40 tons of TNT. [1] The explosion was heard 80 km (50 miles) away.
Electrical steel is an iron alloy which may have from zero to 6.5% silicon (Si:5Fe). Commercial alloys usually have silicon content up to 3.2% (higher concentrations result in brittleness during cold rolling). Manganese and aluminum can be added up to 0.5%. [1]
An explosion tore through an Ohio metals plant on Monday, killing one person and injuring at least a dozen others, officials, witnesses and a media report said.
Sir Robert Abbott Hadfield, 1st Baronet FRS [1] (28 November 1858 in Sheffield – 30 September 1940 in Surrey) was an English metallurgist, noted for his 1882 discovery of manganese steel, one of the first steel alloys. He also invented silicon steel, initially for mechanical properties (patents in 1886) which have made the alloy a material of ...
Slag from steel mills in ferrous smelting is designed to minimize iron loss, which gives out the significant amount of iron, following by oxides of calcium, silicon, magnesium, and aluminium. As the slag is cooled down by water, several chemical reactions from a temperature of around 2,600 °F (1,430 °C) (such as oxidization ) take place ...
On 15 November 2019, the State Council approved the investigation report, presented by the investigation team of the State Council. The report asserts that the explosion accident was a serious production safety accident: there was a long-term practice of illegal storage of hazardous waste, resulting in spontaneous combustion and explosion.
