Developing a technology for introducing alloy addition to liquid steel during the course of continuous casting process seems be an interesting approach enhancing steelmaking process, especially as effective introduction micro-additives or non-metallic inclusion modifiers is key production highest-quality steel. This paper presents results investigation describing chemical homogenisation in two-...

To solve the instability of liquid steel in continuous casting process and inconsistent flaw detection heavy rail steel, flow control was studied numerically a tundish with porous baffle wall by using fluid dynamics software Fluent. The opening plan improved through orthogonal optimization design holes wall. test condition set to left inclination angle α1 = 22°, right α2 48°, an upward elevatio...

In response to the frequent problem of inconsistent quality billet castings and their rolled products from each strand by a five-strand tundish, flow field in tundish is optimized presenting new control devices conducting isothermal physical modelling along with numerical simulation. The results show that dead volume fraction case A6 reduced 27.74% 19%, stagnation time prolonged 12 s 35 s, dyna...

Abstract A transient multiphase flow model is established by solving the heterogeneous dynamic equation to simulate process of slag entrapment in tundish, which can provide data for trial production reduce tundish residue on premise ensuring no entrapment. numerical simulation critical height 60 t under different steel throughputs analyzed, and following conclusions are obtained: when throughpu...

Abstract There are few studies on the shape and structure of channel-type induction heating tundish multi-physics field. Computational fluid dynamics has been used to study influence macroscopic transport behavior with channel heating. The results show that increasing depth molten pool is conducive dynamic multiphase, deeper pool, larger active area, longer residence time, more inclusions remov...

 Abstract Background: Distal Radial fracture is one of the most common fractures of the skeletal system. Although it has been believed to be a simple fracture with excellent outcomes, practical operations’ results have always been undesirable and even poor. The goal of this study was to compare two methods of treatment “pin and plaster and precautious pin fixation in patients with unstable extr...
