STANDARD MATERIALSPhosphorus de-oxidised copperThis alloy has been proven to be excellent for the manufacture of moulds in the continuous casting of billets .The main composition of this alloy are Cu +Ag 99.90min,P0.0015/0.040.Copper -Silver alloyThe addition of a small amount of silver ,whilst not increasing the melting point of copper ,does increase the recrystallisation temperature by almost 100℃,and also helps to give better thermal conductivity at the operating temperatures.This alloy is normally used in moulds for the continuous casting of blooms and slabs .In this case ,the moulds are much thicker than in the billet moulds ,and the moulds temperature can be higher.The main composition of this alloy are Cu+Ag99.90 min. Ag 0.08/0.12 O 0.004/0.012.COPPER MOULD TUBE  The continuous casting of molten steel into billets ,blooms and slab products ,has been highly refined over the years into an extremely sophisticated system .The continuous casting process is expected to produce metallurgically sound products at the lower possible cost ,and this is being achieved in many steelworks throughout the world.Copper moulds have played an important role in the development of the continuous casting process .Their funcition is to receive the molten steel and to allow rapid heat transfer from the steel to the cooling water to enable quick solidification.The mould must exhibit excellent thermal conductivity ,be resistant for thermal erosion ,and be resistant to distortion from thermal stress .So far only copper and a few copper alloys meet the above conditions ,both economically and technically.SOLIDIFICATIONThe rate of solidification in the continuous casting process dictates the speed of production .The molten steel ,which is in contact with the inner faces of the copper mould ,starts to sllidify as rapidly as the heat is extracted ,forming a shell .The shell increases in thickness as more heat is extracted ,and eventually total solidfication is achieved .the process is similar to the solidification of ingots in ingot moulds .In continuous casting ,the whole process is speeded up ,with the aim to produce and homogeneous shell growth.Consequently ,the mould is an important part of the continuous casting process ,and the manufactured quality of the mould plays and important role in their length of life.INNER SURFACE COATINGSOver the years ,Metallurgists and Engineers have been working together to develop better continuous casting moulds .The steel companies require a more economical mould which will give a longer service life .Surface coating of the inner walls of the mould has given the best results to date .Coatings available are Chromium and Nickel plating .Also,a combination of the two give good results on slab casting.SPECIFICATIONS OF COPPER MOULDSquare Copper mould tubeSquare 60x60-350x350(mm) Rectangle 120x160-180x300(mm)Round Copper Mould tubeDiameter 100-400(mm)Size(mm): 90x90,100x100,110x110,115x115,120x120130x130,135x135,140x140,143x143,150x150155x155,160x160,165x165,175x175,180x180200x200,220x220,100x170,100x173,130x240150x200,150x210,150x220,160x200,160x220150x225,160x235,165x225,175x225,180x220200x240,240x240,235x235Radius(mm): 4000,5000,5250,6000,7000,7500,8000,9000,10250,10300,11000,12000Length(mm): 700,750,780,790,800,810,812,850,900,1000
