Embodiment Construction

[0023] The following description and examples of the present invention should not be used to limit the scope of the present invention. Other examples, features, aspects, embodiments and advantages of the invention will be apparent to those skilled in the art from the following description. As will be appreciated, the invention contemplates alternative embodiments other than those exemplary embodiments specifically discussed herein without departing from the scope of the invention. Accordingly, the drawings and descriptions should be regarded as illustrative and not restrictive in nature.

[0024] figure 1 A typical continuous casting machine (10) is shown having a ladle (20) coupled to a feeder trough (50) through a ladle shroud (26). As shown, the liquid steel (2) stored in the ladle (2) flows through the ladle nozzle (22) to the sliding gate (24). The sliding gate (24) can be opened and closed by selectively aligning the opening (23) of the sliding gate (24) with the lad...

Abstract

A continuous casting machine is provided that includes a refractory tundish funnel. The tundish funnel has a tapered shape and is designed to sit on a tundish lid in order to channel steel from the ladle to the tundish bath. A collector can also be provided to channel the steel from the ladle. The collector has an opening with a cross-section that transitions from a cylindrical shape to a cross-shape.

Description

[0001] priority [0002] This application claims priority to U.S. Provisional Application No. 62 / 372,431, filed August 9, 2016, entitled "TUNDISH FUNNEL," the disclosure of which is incorporated herein by reference middle. Background technique [0003] Continuous casting is used in steel manufacturing to create semi-finished steel shapes such as ingots, slabs, blocks, billets, etc. During a typical continuous casting process, liquid steel is transferred to a ladle, where the liquid steel flows from the ladle through a feed trough and into the mold. Feed troughs are large containers that hold a reservoir of liquid steel to be distributed to the mold in a continuous flow. [0004] In some instances, oxygen formed in the liquid steel can create defects, such as pinholes, in the steel. To reduce the occurrence of such defects, the liquid steel is deoxidized or killed, and during the continuous casting process, refractory ladle shields are usually inserted from the ladle into t...
