The goal of the latest strategy in glass companies is to decrease the cost of production while maintaining or increasing the glass quality. There are several perspective ways leading to this goal: Optimization of the heating system, Modification of the furnace design, or Installing the new advanced control system. Optimization of the heating system can be achieved by installing modern burner sy...

A lot of metallurgical processes take places in shaft furnaces, where reacting gas carrying powders flows up in packed bed of descending metallurgical materials. Gas + powder two phase flow in fixed packed bed has been investigated by author for many years 1 . At present author undertakes the investigations with moving bed. Physical model with glass bed and glass powders was constructed. The ex...

The basic areas of devices condition management through Autonomous and Professional Maintenance are described here. Mentioned areas of activities are per...

The article is devoted to the problem of origin iron metallurgy and formation first large metallurgical center in territory Southern Siberia. On basis archaeological radiocarbon data, it was concluded that not a single iron-smelting furnace Scythian time southern Siberia known. oldest smelting sites appeared region 1st century BC — AD were associated with Xiongnu traditions building oval furnac...

This paper concerns the mathematical modelling and numerical solution of thermoelectrical phenomena taking place in an axisymmetric induction heating furnace. We formulate the problem in a two-dimensional domain and propose a finite element method and an iterative algorithm for its numerical solution. We also provide a family of one-dimensional analytical solutions which are used to test the tw...

Power quality is becoming a more concern of today’s power system engineer due to rapid growth of non-linear loads in distribution network. Electrical Arc Furnace (EAF) is one of the responsible causes for deteriorating power quality in the distribution network. Hence electric arc furnace model is needed to study and to analyze the power quality in the distribution network. This paper presents a...

The design of system for operative planning of blast furnace production process in VSŽ inc. Kosice A system for operative planning of blast furnace production process is described in the paper. The suggested system is based on the use of a new hierarchy of operative plans, consisting of one-month plan, (7+3) days plan, and 24-hour plan. The system allows smoothing of production process at the b...

abstract: friction stir welding, a solid state innovative joining technique, is widely being used for joining aluminium alloys for aerospace, marine automotive and many other applications of commercial importance. fsw trials were carried out using a vertical machining centre (vmc) on aa6061 alloy. the main objective of the present work was to evaluate the weld processing parameter of friction s...

air cooled blast furnace slag is a by product made of gradually air cooled molten blast furnace slag, and is often stored in stockpiles near the iron mills and usually occupy a wide area around the iron mills. from this perspective the further use of these materials can have its own merits. air cooled blast furnace slag can be used in asphalt mixtures because of their proper frictional properti...
