Continuous casting is a method of producing an infinite solid strand from liquid steel by continuously solidifying it as it moves through a CC machine.
To transfer liquid steel from a teeming ladle to the continuous casting machine mould, an intermediate vessel, called a tundish, is used.
The continuous casting tundish serves as a buffer and links the discontinuous process of the secondary steel making in the ladle with the continuous casting process in the mould. It acts as a reservoir during the ladle change periods and continues to supply liquid steel to the mould when incoming liquid steel is stopped, making sequential casting by a number of ladles possible.
Many steel plant operators have studied their tundishes in order to maximize the benefits of the residence time available for the floatation and assimilation of reaction products from the liquid steel into the slag phase. These can be products of deoxidation, reoxidation, precipitation, emulsification and/or entrainment of refractory components into the liquid steel, and thus encompass both indigenous and exogenous inclusions. Based on a sound choice of tundish design, the operation of a tundish needs to be geared to the following.
- To promote inclusion floatation by maximizing residence time
- To ensure inclusion assimilation by a captive and noncorrosive slag
- To reduce thermal and chemical losses from the liquid steel
- To minimize short circuiting and dead zones
- To offer the operator an optimal design for quality and yield.
The steel industry is undoubtedly an important contributor to the economy. Most of the construction companies available in the market uses steel frame to build heavy infrastructure, and some of the main reasons owing to which steel frames is used over other types of infrastructure available in the market is its benefits which it gives to its customers.
Advantages of steel framing
Generally,building construction is finished with the help of mild steel instead of using the most powerful tool present in the market. This mild steel is very durable and strong to use, and can be used under every circumstance or for building strong infrastructure and buildings. The features of steel framing is as following:
1. Flexible, The mild steel frames can be easily bended or molded according to the comfort of the user.2. Ductility, The soft and appropriate material of the frame will not crack in extreme conditions and instead stays intact to be used for different purposes on the construction site.
3. Durable, These are very durable to use, because they can last for a longer period of time and users need not have to bear cost for replacement again and again.
Where to use steel frames?
Before the steel frames or different kinds of cladding rails are put to use, it is important to understand what their different types are and uses which can deliver the best output to the users. Following are the kind of frames which can be used;
Fujian Putian Geili Machinery manufacturing Co., Ltd was founded in 2006, the registered capital of 20,000,000 yuan. The company is located in one of the city center onn the west side of the Straits Economic Zone, Xianyou Putian. We are not only a manufacturer of steel machinery, but we have our own steel mill, which can produce deformed bar, angle bar, round steel, wire rod, steel coil, steel plate etc. If you have inquiry in these area, pls don't hesitate to contact us.
