This paper discusses different alternatives of more efficient preparation of spheroided graphite cast iron production. Secondary metallurgy and chemical heating technology are used to recast cast iron fused in copula furnace. The work applies the known physical-chemical rules used in the production of quality spheroided graphite cast iron in regular production conditions. Based on the previous developments, the aim was to prepare implementation of verified secondary metallurgy processes in adjusted casting ladle. The casting ladle was adjusted in order to allow execution of all processes required in order for the relevant standards and material lists requirements to be met in respect to spheroided graphite cast iron quality. Comments regarding the trends in ferroalloy metallurgy and related marketing approach of the company. The work is concluded by a summary of advantages brought in by the new approaches compared to the traditional ones from the economical as well as environmental perspective.

Until a few decades ago few people could imagine that the photovoltaic, solar thermal and other power based on renewable resources, will become a reality. Today people from all over the world on the contrary try at full blast derive benefit from of all possible available source. Using sunlight as a source of energy is first enforced only for small devices such as calculators for charging the battery, but now we are able to produced energy from the sun to supply people around the world. Of course it is not possible supply consumer sector plus firm only from performances renewable power supply. Therefore endeavour is derive benefit from classical energy production at the same time with others power supply. The basic components of photovoltaic and solar thermal power are panels. The panels are made of different materials in different shapes and sizes. During production, the resulting effect looks in addition to costs associated with production. For photovoltaic and solar thermal power plant requires sufficient sunlight. The sunshine has biggest intensity on south of ours planets. Therefore endeavour is build lump these power station just in stand with bigger intensity sunshine. One of them is just Cyprus, too.
