In other word, without casting powder, CCM technology can not reach current level.Therefore, casting powder is an important part of modern CCM technology. Every country is investing a great labor and money in developing casting powder to satisfy CCM production requirement, which improve the developing of CCM technology.There have many kinds of refractory products in our factory.

1.Making continues casting stable, ensure that the continues casting can move on smoothly.
2.Improving steel billet surface and under-surface steel quality.

Function of casting powder in mould is as following,
1.Casting powder can create an insulation layer on steel level, which can help to keep temperature of the melton steel.
2.Protecting the melton steel from secondary oxidation.
3.Casting powder can absorb floating inclusion in melton steel.
4.Casting powder has a good function of floating.
5.Casting powder can help to control the heat conducting.

There also have many kinds of refractory products in our factory,such as clay insulating bricks, fire brick ,refractory raw materials,refractory nozzle, etc.When you need any refractory products,welcome to view our website to know more kinds of refractory products.
