Translation of "Einsatzgut" in English

The feedstock to electric arc furnaces often contains oils, emulsions or greases.

For agriculture, pesticides are a valuable input.

The input material can also be introduced in the wet state.

At least a portion of the slag is recycled and mixed with the charging materials of the reactor.

The scrap and waste in question is usually put to fresh use as raw material.

The starting material had the following composition (data in % by weight):

In the planetary roller extruder the feedstock is rolled in a thin layer between the inter-meshing teeth.

To feed an arc furnace with solid charging material, its shell must be made accessible.

This is, in general, only obtained with charge material of high bulk density, so-called coarse scrap.

It is apparent that the charge consists of sponge iron having a relatively high carbon content and good metallurgical properties.

In addition, the deformation of the used material performed by the extruder spindles causes a considerable heating.

If, on the other hand, the product is simply another input into the final product, it must be carefully examined whether the licensed technology constitutes the primary object of the agreement.

This is also the case where one party grants a licence to the other party and accepts to buy a physical input from the licensee.

In cases where the licensed technology relates to an input which is incorporated into a final product it is as a general rule not restrictive of competition that royalties are calculated on the basis of the price of the final product, provided that it incorporates the licensed technology.

According to still another feature of the invention, the falling slag is at least in part recycled by mixing with the reactor charging materials.

Such mixing of the slag with the charging material facilitates reaching the high temperature required for gasification.

The deviation of these differences from the minimum distances desired for for achieving the pre-set desired values can be diminished by the addition of of preheated coal to the charge.

By sucking off of the zinc-containing gases from the plane 28 located below the depth, the surface temperature of the furnace charge can be adjusted such that the green charged material is not subjected to a thermal shock.

To this effect, at least one of the pipes (24) coming from the thickener (22) leads to an inlet of the grinder (25) where the slag is ground with the other charging materials.

The pump (28), which is connected to the stirrer (26) and forces the charging material into the boiler, works in relation to the operating pressure required for the reactor.

A direct current arc furnace has at least one anode movable into the furnace interior and at least one cathode also movable from above into the furnace interior, between which cathode and the inserted material or the melt an arc is produced.

Irregularities in the charging lead to an ununiform amount of outflow, since the solid charging material resting on the melting bath exerts a pressure on the melting bath in dependence on its weight, which has a direct effect on the outflow amount per time unit.

By this measure, the pressure exerted by the granular charging material on the melt and thus the outflow of the melt is made still more uniform.

Under the conditions of the gasification, chlorine-containing organic compounds primarily contained in the material being used are completely converted, wherein the chlorine content is converted to hydrogen chloride or non-toxic inorganic chlorides.

The gasification in the flow path has the disadvantage that the material being used for the gasification process must be present in a flowable form, so that the material can be fed into the gasification reactor in a continuous and controlled manner.

Experience in combustion technology has shown that substances contained in the material or substances newly created during the combustion as well as volatile heavy metals vaporize, are sublimated at the subsequent heating surfaces and form projections together with slag droplets suspended in the flue gas and incompletely burned coke particles, which projections cause interruptions in the operation and the continuous removal thereof also requires high investment and operating costs, and may impair the efficiency.

Advantageously, the dosing pipes are each provided with a wall recess extending vertically upwardly from the mouth and located at the sides facing the electrodes, whereby in the region of the electrodes more charging material is present.
