Introduction
Hot sill and heat charge technology are two advanced casting technologies. They can improve the quality of billet and obtain higher production accuracy. They are becoming more and more popular in the manufacturing industry. There are many advantages to using these two technology. This paper will discuss the advantages and principles of hot-sill technology and heat-charge technology in continuous rolling billets.
Advantages of Hot Sill and Heat Charge Technology
Continuous casting billets are an important part of the contemporary steel manufacture industry. The quality of billet directly affects the production process of steel and its products. Therefore, it is very important to choose the appropriate casting technoloigy. Hot sill and heat charge technology are two of the most advanced technologies for billet casting. They are becoming more popular in recent years.
Hot rolling of billets can improve their quality. It can also reduce their surface oxidation and produce uniform wettability. With the help of these two advanced casting technologie, the surface can achieve better uniformity, the shape can be reduced and the rolling accuracy can be improved. Furthermore, these technologies can reduce the cost of billet production.
The production speed can be improved due to the combined use of cold and hot rolling processes. The billets can move through the mold more quickly and hence more billets can be produced in less time. Furthermore, the combined use of both technologies can help to control internal oxidation and improve metallurgical properties.
Principle of Hot Sill and Heat Charge Technology
Hot Sill technology is a hot compensating pouring process. The steel pipe enters the pouring area at a certain temperature and is poured into the bottom of the casting die. A curtain of hot steel pipe then flows down the walls of the die cavity and the billet emerges at the end. The billet is then rolled at a uniform temperature allowing for improved uniformity and shape.
Heat charge technology is a preheating method in which cold billets are preheated before being poured into the die. This preheating helps to reduce thermal shocks that can occur during the rolling process. Heat charge also help to reduce oxidation, producing a better quality billet.
Conclusion
Hot sill and heat charge technology are two of the most advanced casting technologies in the billet production industry. They offer many advantages such as improved accuracy, reduced cost, improved production speed and control of oxidation and metallurgical properties. Additionally, they help to produce more uniform billets by providing uniform temperature throughout the rolling process. Furthermore, these technologies can reduce thermal shocks. As a result, hot sill and heat charge technology are becoming increasingly popular for continuous rolling billet production.
