Eel fractory materials areare built against the inner wallthesteel steel shell in order, that are refractory materials built against the inner wall on the steelshell in order, which are inner fractory components are constructed against the inner wall of of your shell in order, that are inner (functioning) layer, back (security) layer, and insulating layer. This study took 130-ton130-ton inner (operating) layer, (security) layer, layer, and insulating layer.study study took of slab (working) layer, back back (security) and insulating layer. This This took 130-ton of slab steel ladle asladleresearchobject. Among the backthe back layer and steel shell, avoiding of slab steel the investigation object. Involving the backlayer and steel shell, avoiding the steel steel ladle because the because the study object. Involving layer and steel shell, avoiding the steel nails on the steel shell, were pasted two layers of layers ofthicknessSACIP with castable. the steel nails on the steel shell, weretwo layers of20 mm thicknessthicknesswith castable. nails around the steel shell, were pasted pasted two 20 mm 20 mm SACIP SACIP with the profile structure structure ofladleis shown is shown in Figure four. castable.

Surface Temperature of Outer Steel Shell two.two.1. Numerical simulation of Temperature Field of Steel Ladle Wall (1). Establishment of Model Without affecting the calculation outcomes, as a way to facilitate the establishment on the model, the following assumptions have been proposed [24,25]: (1). The steel ladle trunnels, bottom breathable bricks and a few driving devices structural reinforcements valves have little impact around the temperature field within the FEM of steel ladle wall, so these components are omittedCoatings 2021, 11,five ofin the model; (2). The contact thermal resistance in between the steel ladle insulating layer and also the steel shell is negligible; (3). Because of the compact slope angle of your steel ladle, the steel ladle is usually regarded as a cylinder soon after removing the mechanical components for loading and unloading about the steel ladle; (4). The temperature of molten steel will be the exact same everywhere in the steel ladle; (five). Since the steel ladle has axially symmetrical geometry, a a part of the steel ladle wall is taken for the FEM. The thermal conductivity equation is shown in Equation (1). 2 T 2 T + 2 r2 z=(1)exactly where is the thermal conductivity of the material, W/mK; T may be the temperature, K; r would be the normal Almorexant supplier distance, m; z is axial distance, m. (2). Meshing Figure 6 is often a 2D model from the ladle wall which was created by SOLIDWORKS 19.0, and imported into APDL of ANSYS 2020 R2 for processing. Mainly because it’s a strong heat transfer model, plane 77 was chosen especially for the heat transfer model which is a 2-dimensional 8-node thermal unit entity (each and every node has only one degree of freedomtemperature, and each element has a consistent temperature shape function), suitable for 2D.
