An Introduction To Tundishes

Modern metal production simply wouldn’t work without tundishes, where production would be inefficient and more costly. Through the use of refractory-lined tundishes, the process of metal casting is greatly enhanced. The core components of tundish linings such as chromite and anthracite are available from African Pegmatite - the preferred industrial provider for a wealth of refractories and minerals for the foundry industry. A tundish is a device used in the casting of metals. It is any open-topped vessel with holes in the bottom to deliver molten metal at a controlled rate into casting moulds. It is often used between smelting and casting to ensure a consistent and regulated flow, whilst enabling the switchover of casting moulds if needed. Tundishes are often made of steel and are lined with some kind of liner, which is always a refractory material, often in brick form.

Tundish nozzles are basically used for controlling the flow of steel from the Tundish to the Continuous Casting equipment. Different kind of tundish nozzles include, Alumina, Alumina Carbon, Zirconia Alumina Nozzles, which are manufactured for single to multiple casting application.

Silicon metal is a grey and lustrous semi-conductive metal that is used to manufacture steel, solar cells, and microchips. Silicon is the second most abundant element in the earth's crust (behind only oxygen) and the eighth-most common element in the universe. Nearly 30 percent of the weight of the earth's crust can be attributed to silicon. Silicon metal is mainly used by the chemical industry in the production of silicon compounds and by semiconductors.

How the slag ball mill turns slag into treasure ?

As a kind of metallurgical waste, slag will not only pollute the environment, but also waste resources. After being processed by ball mill, slag can be turned into fine slag powder and used as raw material for concrete and cement, which effectively improves the economic utilization value. This paper will introduce the slag ball mill in detail from three aspects: processing principle, parameters and characteristics and market price.What equipment can process slag into slag powder to turn waste into treasure? Slag ball mill has this magic. It is a "artifact" that can turn slag into slag powder. It can grind slag to 0.074mm-0.89mm. The working principle of slag ball mill is the same as that of ordinary ball mill, which depends on the steel ball medium in the cylinder to grind the materials. When the slag enters the cylinder from the feed end, the centrifugal force generated by the rotation of the cylinder will bring the steel ball to a certain height. The high steel ball falls down in a parabolic trajectory due to gravity and collides with the slag with great impact force.

What is a carburizer Carburizing agent is the product of increasing carbon (c). In the process of steelmaking, due to various factors, the carbon content in molten steel decreases, which affects the quality of finished steel. Therefore, steel mills often buy carburizing agent in order to deal with the carbon decline in steelmaking. There are many common types of carburizers, including graphite carburizers, petroleum coke carburizers and casting carburizers, which are mainly used in steel-making and casting industries.
