Modeling of Air Entrainment During Pouring of Steel Castings. Seyyed Hojjat Majidi and Christoph Beckermann. Department of Mechanical and Industrial Engineering. The University of Iowa, Iowa City, Abstract. Air entrainment mold fillingduring is known to be a major source of reoxidation inclusions in steel castings. An Example in Steel Casting The One Person Hitch Housing for the 2 ½ and 5 Ton Trucks The Application – The one person hitch housing is part of an improved hitch/frame design for the military’ s 2½ and 5 ton trucks, used for towing weapons systems, cargo trailers, and other payloads. The hitch housing acts as an alignment and locking fixture.
Ladle changes in continuous casting machines result in liquid steel level changes in tundishes. During this transient event of production, the flow rate controller opening is increased to reduce the pressure drop across the opening which helps to keep the mass flow rate at the desired level for the reduced liquid steel level in tundish.

Authors; to the nozzle holder on the bottom of the ladle does not provide a good protection effect because air can easily flow into the teeming system and cause reoxidation of molten steel during teeming. By contrast, an argon shroud protection device seated on Author: Chao-jie Zhang, Yan-ping Bao, Min Wang, Le-chen Zhang.
May 01, · Experiments using mechanical shrouding at Wisconsin's Pelton Casteel and Falk Corp. in the mid-to-late s revealed that mechanical shrouding alone held some promise. In particular, a mechanical shroud on a lb production part at Falk reduced pouring time, and improved the cleanliness of the casting and subsequent machining.
control of fluid flow conditions. This chapter summarizes some of these problems and discusses the effect of continuous casting parameters on controlling the flow. The flow system and its ter-minology are illustrated in Fig. a and b. The task of the flow system is to transport molten steel at a desired flow rate from the ladle into.

Tundish Technology for Casting Clean Steel: A Review YOGESHWAR SAHAI With increasing demand of high-quality clean steel, cleanliness is of paramount importance in steel production and casting.
Tundish plays an important role in controlling the continuously cast steel quality as it links a batch vessel, ladle, to a continuous casting mold.

Modelling of liquid steel flow with free surface electromagnetic stirring of a continuous casting facility for steel bars, in order to explore the influence of operating parameters such as the. engineers and the foundry’s casting engineers is essential, to optimize the casting design, in terms of cost and performance.
Additional guidelines for casting design are given in “Steel Castings Handbook” and Supplement 1,3, and 4 of the “Steel Castings Handbook”. Minimum Section Thickness.
FUNDAMENTALS OF METAL CASTING •For this step to be successful, metal must flow into all regions of the mold, most importantly the main cavity, before solidifying •A casting with a higher volume-to-surface area ratio cools and solidifies more slowly than one with a lower.

Mar 16, · It supplies molten steel in presence of a slag cover to all continuous casting molds constantly and continuously at constant steel flow rate. The flow rate is maintained constant by maintaining a constant steel bath height in the tundish through teeming of molten steel from the ladle.
The number of mold is either one or more than one. mold of a continuous casting machine as shown by Yoshida et al. in Fig. , and is solidified as slabs, blooms, or billets. In the last three decades, continuous casting has become a mature technology for the solidification of steel. Today, continuous casting has almost.

Transient fluid flow in the continuous steel-slab casting mold Brian G. Thomas, Quan Yuan, S. Sivaramakrishnan, and S.P. Vanka The quality of steel produced from continuous casting is greatly affected by fluid flow If the steel flow velocity across the top surface is too great, it.
software can be used, in place of actual casting trials, to detect feeding and risering problems in a steel casting, the present rules still serve several important purposes: • Casting simulation does not provide the initial riser design for a casting; the present rules can be used to develop the first “trial” riser design.
Apr 16, · As far as steel casting is concerned, this is a special type of casting known to use various kinds of steel. This is particularly used when cast iron shows lack of strength and resistance.
Among the fields and industries where steel casting is popularly used are in .Steel - Steel - Continuous casting: About 55 percent of the world’s liquid steel production is solidified in continuous casting processes, the most widely used of which feeds liquid steel continuously into a short, water-cooled vertical copper mold and, at the same time, continuously withdraws the frozen shell, including the liquid steel it contains.changing casting speed if the need arises or for changing the nozzle if erosion, cracking or clogging occurs.
Open casting means no steel jet protection during transfer from ladle to tundish and from tundish to molds, with an exception for low carbon steel. In some cases, the injection of aluminum wire into the mold is still practiced.
