WitrynaThe iron that comes straight out of the blast furnace is called pig iron, and it tends to be very brittle because it contains 2 % – 5 % carbon and other types of impurities. Some of the pig iron is placed into molds to make what is known as cast iron. Cast iron is primarily used to make pans, drain covers, engine blocks, and fences. WitrynaA casting defect is an undesired irregularity in a metal casting process. Some defects can be tolerated while others can be repaired, otherwise they must be eliminated. They are broken down into five main categories: gas porosity, shrinkage defects, mould material defects, pouring metal defects, and metallurgical defects.
WitrynaImpurities in the cast iron raw material were removed using this device. The treatment was carried out with 500 kg and 1000 kg of melt by weight fed to the treatment device 7. The experiment conditions are shown below. 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.

Introduction. Degeneracy of spheroidal graphite in cast irons is contemporary to the discovery that small additions of cerium [ 1] or magnesium [ 2] to the melt before casting changes the graphite shape from lamellar to spheroidal.
