 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. Such refractory materials employed as tundish linings, or of components in tundish linings, include anthracite, chromite and glass powders amongst others. Some 7% of all refractory materials in Europe are used for tundishes and in continuous casting(1,2), with a respectable 5% of this going to landfill after use(3). Tundishes are closely related to ladles, which are used to transport molten metal from the furnace to the tundish ahead of casting. These large, refractory lined buckets are operationally very similar to tundishes and thus the principles for tundish lining design and materials largely apply to ladles as well. Overall, it can be said that an ideal tundish lining will have the following qualities:

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. The tundish is a refractory container, and the molten steel poured from the ladle is distributed to each mold through the tundish metering nozzle.The quality and life of the tundish nozzle directly affect the purity of steel before entering into mold. Tundish nozzle is divided into two types: argon blowing and non-argon blowing. The tundish nozzle is embedded in the seat brick at the bottom of the tundish and used in conjunction with the stopper. The tundish nozzle is mainly used to adjust the flow of molten steel entering the mold, and argon can be blown through the inner wall to prevent the nozzle from being blocked. 

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. 

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. 

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.
