It is shown that the distribution of ends tubular billets, which are main connecting elements vehicle brake system, accompanied by a loss stability in circumferential and axial directions, as well localization deformations, followed destruction form longitudinal crack occurs at end preform. The presence weld complicates general conditions deformation during crimping leads to workpiece along wel...

Metallurgical aggregates, which are used for metal waste melting, equipped with lances blowing gaseous media. These media allow especially scrap melting and intense homogenization of the resulting melt. In connection this, systems developed both itself on bath surface or into melt gas mixture powdered substances. When designing individual lance tips nozzles, it is necessary to respect certain c...

The aim of this case study is to implement the Lean Six Sigma methodology reduce scrap rate edge-bending process a metal door used in assembly refrigeration appliances. This was initiated because refrigerators does not work at maximum capacity due that occurs for component. Losses have direct effects on company’s profits and its competitiveness market. research provides an overview identificati...

In this study, old scrap tire powder was used with building materials commonly in Iraq, where it some brick holes the form of 0-1 mm ( crumb rubber without fabric and metal), case, called bricks [STP-I]. It compared traditional wall that does not contain tires, [No STs]. A test room has been build prepared for purpose a heating source 8 hours applied on each wall. The comparison by measuring te...

The continuous increasing consumption of metals during the last decades caused a considerable growth of anthropogenic stocks. But, knowledge regarding quantity, quality and availability of material from these stocks is still quite limited. This study aims at analysing anthropogenic aluminium (Al) stocks and flows in Austria utilising a dynamic material flow model. The amount of Al currently sto...
