Abstract

Experimentally using electric vibration viscometer and the method of design of experiments on the simplex studied the melt viscosity of the system CaO - SiO₂ - Al₂O₃ - MgО. Developed its mathematical model and computer program that allows calculation of viscosity in the temperature range 1 573 - 1 823 К. Using the model diagrams are constructed in the form of isothermal sections of the tetrahedron on MgO. It is concluded that the use of the model is more efficient than Chart, so it does not require a complex geometric constructions tetrahedron when the viscosity values, and, moreover, can be used in automatic process control in real time.
