Abstract: In this paper, a new solution of solidification problems in continuous casting based on meshless method is presented with multiple strategies to solve the practical problems. An additional term is added to stabilise the computation with Neumann boundary. The enthalpy method is used to calculate the latent heat and the corresponding iterative solution is given. An iteration scheme for ...

Among many factors which affect the dimensional accuracy of dental castings, several mechanical factors have been selected and studied theoretically and experimentally by the authors1-4). The analytical method employed in those studies showed clearly the effects of mechanical conditions on the deformation of wax patterns and castings in molds during the casting process. The results of the analy...

Phase separation simulation study related to cellulose acetate-water-acetone has been done. Results show that porous asymmetric and symmetric membranes can be produced by changing the nonsolvent concentration or by the drying conditions without altering the polymer content using dry-casting process. Dry-casting process is the process in which complete evaporation of solvent and nonsolvent takes...

This paper stablishes the model of the integrated batch planning process, and proposes an improved algorithm for this problem. The simulation results of a computerized scheduling system are given to prove the fitness of the model. The steel making casting production process scheduling problem is very difficult to get a good performance solution in practice. The scheduling of steelmaking casting...

A reoxidation inclusion model is described that simulates the entire life cycle of inclusions during the filling of steel castings and predicts their final location in the casting. Inclusions can be released into the mold at the inlet and/or nucleate on the metal free surface, where contact with oxygen from the atmosphere creates them. Inclusion motion is calculated by solving an equation of mo...

Aluminothermic welding has been used to connect railway rails for over a century. This technique the advantages of flexibility, weld compactness, and simplicity. External energy is not required procedure. Exothermic heat produced by chemical reactions aluminothermic elements. To create quality welded connection, mold pouring system must provide uniform hot steel without turbulence, even dissipa...
