A novel process for producing molten pig iron or steel raw material is described. The pig iron is initially at least partly reduced to sponge iron by means of a reducing gas and is then melted in a melting gasifier, being optionally finally reduced. Apart from the sponge iron, the melting gasifier is supplied with coal at least partly degassed by a hot gas and oxygen-containing gas. The hot gas us...

In a ribbon consisting of a cross-linked plastic which can be shrunk by the action of heat and can be placed in the manner of a collar (2a) around an elongated object (4), and after the connecting together of the edges (3a, 3b) of the ribbon, can be shrunk onto the object (4) by the action of heat. The edge regions (3a, 3b) of the ribbon consist of non-cross-linked plastic and a connecting togethe...
