WO1985000186A1 - Converter for the smelting of steel - Google Patents

Abstract

The converter for smelting steel comprises a body (1) so fabricated that it may turn about trunnions (6) of its supports (5), bottom tuyeres (2) and lateral tuyeres (3) provided for supplying oxygen and a fuel, which tuyeres are arranged in a refractory lining. The lateral tuyeres (3) are so arranged that a geometrical axis (7) thereof intersects a vertical axis (8) of the converter at a point (9), which is defined lower than an axis (10) of the trunnions (6) at a distance equal to 0.5-1.0 of the distance between a bottom (11) and a locus, where the axis (10) of the trunnions (6) and the vertical axis (8) of the converter are intersecting.

The invention is related to black metal, and more specifically, the inverters for smelting have become more difficult. • Use of the product may be used for the cleaning of steel furnaces, especially for the use of non-corrosive iron, and

The previous level of technology is even more stable, in the case of which the unit is mounted at a 15 ° angle to increase the distance.

However, the combustion process is unstable, since most of the oxygen is consumed by the oxidation of iron.

A steelmaking unit is known, which contains a burner that has been blown up with data and perfumes for the supply of oxygen and fuel (see, for example, US Pat. No. 3912243-34). Generally speaking, the Forum is able to increase the amount of gas that is being handled due to the burning of exhausted gas, which is not

Disassembling the basic invention, the task has been to create an in-line melting vessel, at the expense of changing the angle of the income due to a change in the income tax.

This task is solved in that, in the process for the smelting of steel, which contains a shell executed with the help of the machine, it is possible to recover from it.

The drive has options 5, but the drive 6 is on hand. Volumes 2 and 3 are intended for use in an environment that conserves oxygen, gas and hydrocarbon-containing fuel, such as gas. Lateral Frames 3 are installed so that they are supplied through the product, an acid is supplied, and the metal bath is connected to it.

On the other hand, an increase in the margin of the margin of distribution I does not exclude the release of metal and slag from the burner.
