This work explores the effect of additives on the pouring temperature in a waterworks and industrial calcium fluoride sludge co-melting system. Two kinds of sludge were mixed in various ratios to find a mixing ratio at which the operating temperature for subsequent additive tests was relatively low. Various proportions of either sodium carbonate (Na2CO3) or potassium carbonate (K2CO3) reagent w...

We introduce our work on pouring as an example of complicated tasks for robots. The architecture is a skill library with planning and learning methods. We briefly describe our representation for pouring, then discuss problems and future directions.

Introduction Ingot products account for 8.3% of the total crude steel produced in the world. It is produced either by top pouring or bottom pouring of the liquid in the moulds. The increasing demand for quality steels led to the evolution of bottom pouring technology for casting of steel ingots. This process constitutes of a set up involving pouring sprue and runner system to deliver liquid ste...

This paper is concerned with the pouring control of tilting-ladle-type automatic pouring systems in casting industries. A new approach to the modeling and control system of the pouring process is proposed. In the approach, the flow rate model is described by a nonlinear system with hydrodynamics. The flow rate control system is built by a feedfoward control using the inverse dynamics of the flo...

The high cost of fabrication hindered the actual application of metal matrix composite (MMC) despite of their high stiffness, strength, corrosion resistance, wear resistance, non-reactivity with chemicals and so many other tailored quality which are never obtained in alloy of metals. In this study, a modest attempt has been made to find out the process parameters at which best mechanical proper...

Granular materials are predominantly plastic, incrementally nonlinear, preparation-dependent, and anisotropic under shear. Nevertheless, their static stress distribution is well accounted for, in the whole range up to the point of failure, by a judiciously tailored isotropic nonanalytic elasticity theory termed granular elasticity. The first purpose of this paper is to carefully expound this vi...

Aiming at the construction of infill wall structural column are often used in artificial layer pouring method and top pouring back method, to improve the structure of wall column concrete pouring process, puts forward a new type of structural column concrete pouring machine. The application of this equipment, process worker can finish pouring filled wall structure column and tap filled wall str...
