Professional Provide Copper Mould Tube|Carbon Products-L&T Group

Copper Mould Tube-L&T Group is a British based group of companies.

Through years of shareholding and restructuring reform among the leading members in the group, L&T group has become a professional company serving the world metallurgical and petrol-chemical industry as an integrated group of Copper Mould Tube Manufacturing, Research & Development and trading with its full capacity.

L&T Group does not only provide products and service of our own group, but also offer the related products and service from our long-term strategic alliance at most competitive price.

Our philosophy is to offer our customers a total solution to their Copper Mould Tube requirement for the long-term mutual benefit of all parties.

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 Copper Mould alloys chosen for the moulds must maintain their physical properties at the operating temperatures of the continuous casting process.
The temperature gradation from the inner wall of the mould to the outside face of the mould can cause serious distortion problems ,and it is imperative that the correct alloy is chosen for the various operating conditions.

Copper -Silver alloy
The addition of a small amount of silver Copper Mould Tube ,whilst not increasing the melting point of copper ,does increase the recrystallisation temperature by almost 100¡æ,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.

SOLIDIFICATION

The 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 Copper Mould Tube 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 COATINGS

Over 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.
