From the literature, it is known that due to their glass formation tendency, it is not possible to deposit fully-crystalline silicate coatings when the conventional atmospheric plasma spraying (APS) process is employed. In APS, rapid quenching of the sprayed material on the substrate facilitates the amorphous deposit formation, which shrinks when exposed to heat and forms pores and/or cracks. T...

a mathematical model of a continuous reheating furnace has been developed to identify the design and operating parameters that significantly affect furnace performance. in this study, the furnace is modeled 3 dimensionally and themonte carlomethod is used to find the overall absorption factor. the overall absorption factor is then used to calculate the energy balance for furnace walls, the gas,...

Since the early 1930s, the process of melting glass and subsequently forming fibers, in particular discontinuous fiber glass or continuous glass filaments, evolved into commercial-scale manufacturing. Most commonly, a direct melt process is applied. Thereby, the several raw materials were mixed, fed into a furnace, melted and forwarded to the fiber-forming units. Here, the filaments are formed ...

Introduction Fast, efficient batch melting using the modern induction furnace can improve operating flexibility and production yield, as well as reduce the cost of environmental protection. The compelling advantages of induction batch melting have encouraged foundries to change the way they handle their melting operations. Among the chief advantages is cost. The operational cost of a typical in...
