the effect of inoculant amount and casting temperature onthe choice of inoculant used in grey cast iron production today is probably one of the most important parameters in obtaining the good quality castings. in an earlier investigation2, ten different inoculants were tested and studied by quick cup casting as well as in a commercial casting.material selection method in design of automotive brake disccast iron metallic iron containing more than 2% dissolved carbon within its matrix (as opposed to steel which contains less than 2%) but less than 4.5% is referred to as gray cast iron because of its characteristic color. considering its cost, relative ease of manufacture and thermal stability, this cast iron (particularly, gray cast iron),what is grey cast iron? willman industriesusesadvantagesbenefitscompositionpropertiesclassificationresourcesthere are more pounds of grey iron castings produced every throughout the world than any other type of casting. just about every manhole cover is from grey iron and the disc brakes on your car are most likely grey iron as well. other common uses for grey iron includesee more on willmanind gray iron overviewstructureclassificationsadvantages and disadvantagessee alsofurther reading
gray iron, or grey cast iron, is a type of cast iron that has a graphitic microstructure. it is named after the gray color of the fracture it forms, which is due to the presence of graphite. it is the most common cast iron and the most widely used cast material based on weight.
it is used for housings where the stiffness of the component is more important than its tensile strength, such as internal combustion engine cylinder blocks, pumphousings, valve bodies, electrical boxes, and d · text under ccbysa licensechina foundries metal casting, beijing jinmei gray cast iron, ductile cast iron and steel castings for residential and industrial stoves and boilers, construction and agricultural machinery, pumps, valves, pipe fittings, manhole covers and sewage grids, annual production 10 tons, fbo 3 automatic ming line, resin sand casting line, green sand casting line, hot shell and corefengcheng hanyang industrial co ltd (8459)may 03, 06· our products are grey cast iron, ductile cast iron, steel casting ,gearbox for valves, valves and accessories etc. we already have 5 tons of castings resin bonded sand mould production line, it can make the casting surface roughness and size accuracy enhance 23 levels.cast iron castings foundry cast steel railway castings（）production of cast wheels, casting of cast wheels, rough parts production lines for cast wheels bridge technology is a manufacturer of mechanical parts, engineering vehicle parts, industrial machinery and equipment, sand turning iron castings, cast steel blanks.bic bosphorus international consultancybic manufactures castings from various materials such as grey cast iron, ductile cast iron, cast steel, stainless steel, aluminium, iron and copper as well as forged steel and aluminium parts. our strength is based on sound knowledge and decades of experience in material and forming processes.review enhanced quality in electric melt grey cast ironsreduced, or when cast parts in different qualities (grey iron, ductile iron, compacted graphite iron) are increasingly being demanded from the same foundry production line. consequently, in many parts of the world, such as in asia as a whole, many cupola furnaces have been closed down and
