Thrust grate with a stationary grate component and with a grate component ( ) moved forwards and backwards and is connected to members for its lateral guidance. These members are formed by oppositely arranged tension elements ( ) stretched between the moved grate component ( ) and a stationary structural part ( ) essentially horizontally and perpendicularly to the direction of movement of the grate.

Cooler for combustion products, with a conveyor through which air flows, which cooler is formed by a stationary grate surface (,) and a conveyor (,). The conveyor contains a plurality of drivers (,) moved at a distance from one another over the grate surface. A pre-space (,) is formed at the back of the feed stream fed to the grate (,), which pre-space is delimited on the underside by the conveyor (,) and accommodates a slope of the products to be cooled. The products in the pre-space are intensively cooled and surround the drivers in a protective manner as the latter enter the hot product bed.

The invention relates to a method for blowing oxidizing gases into molten metal located in a reaction vessel having tuyeres below the metal bath surface, whereby the oxidizing gases are blown into the molten metal from these tuyeres and fed to the tuyeres at an inlet pressure between 85 bars and 170 bars.

Method for blowing oxidizing gases into molten metal

In a process for the production of a metal melt in a metallurgical vessel, the filter dusts incurring in producing the metal melt are to be processed to charging substances without causing a load on the environment and without great expenditures. This is achieved in that the filter dusts are introduced into the metallurgical vessel by aid of a gaseous conveying medium composed of natural gas or a mixed gas primarily containing natural gas, the filter dusts being supplied to the metallurgical vessel in a closed system and reduced by the carrier gas.
