WitrynaImpurities in the iron from the Blast Furnace include carbon, sulphur, phosphorus and silicon. These have to be removed. Removal of sulphur Sulphur has to be removed first in a separate process. Magnesium powder is blown through the molten iron and the sulphur reacts with it to form magnesium sulphide. Witryna(1) The running property of the melt becomes worse with increase of the sulphur, and especially worse when the sulphur is more than 0·282%. (2) When the sulphur reaches 0·282%, there appears a chill phenomenon, the shrinkage becomes maximum, and blow holes are found. (3) The combined carbon increases abruptly at 0·282% sulphur. biofilm formation assay kit dojindo

Witryna3 mar 2024 · Silicon has a strong deoxidizing force that reduces the magnetic aging effect of iron. When heated in an oxidizing atmosphere, silicon steel forms a layer of SiO2 film that improves the oxidation resistance of steel at high temperature. Silicon can promote the growth of columnar crystals in cast steel and reduce plasticity. Pouring metal defects include misruns, cold shuts, and inclusions. A misrun occurs when the liquid metal does not completely fill the mould cavity, leaving an unfilled portion. Cold shuts occur when two fronts of liquid metal do not fuse properly in the mould cavity, leaving a weak spot. Both are caused by either a lack of fluidity in the molten metal or cross-sections that are too narrow. The fluidity can be increased by changing the chemical composition of the metal or by increasin…
