Definitions
- the invention relates to a tapping tube for a metallurgical melting vessel.
- a metallurgical melting vessel is understood to mean an aggregate in which a metallurgical melt is produced, treated and / or transported, for example a converter or an electric arc furnace.
- a molten metal in the melting vessel is passed along the tapping tube in a downstream unit.
- the steel is fed from the converter via a ladle to a downstream continuous casting plant.
- the molten metal should be transported as possible without contamination. For example, contact with the ambient atmosphere (oxygen, nitrogen) should be avoided, as should slagging.
- a converter tap is known, which is composed - in the axial direction - of several refractory blocks or slices.
- the inlet-side block should have a funnel-shaped passage and at the outlet end, the passage of the tapping pipe should have the smallest diameter.
- Tapping tubes of this type have been on the market for 20 years and have proven themselves. Also have proven tapping pipes whose geometry at the outlet end corresponds to the requirements of DE 42 08 520 C2. The calculation of the outlet cross-section is based on a flow profile of the corresponding melt, namely assuming an average value for the height of the melt above the tapping tube.
- the height of the molten metal (bath height) during tapping is often almost constant, because the converter is tilted (fed) with increasing tapping time.
- the bath height inevitably decreases.
- this increases the danger that slag will be conducted with the molten metal into the tapping pipe and through it. It can also lead to the formation of turbulence and the formation of a negative pressure in the tapping pipe. At the same time, this increases the risk of reoxidation and nitridation.
- the object of the invention is to optimize a tapping pipe of the type mentioned in such a way that it ensures the desired ("continuous") mass flow during the entire tapping time and prevents the slag from being carried along.
- “Steady” means that the mass flow in the tapping channel of the If possible, do not tear off the tapping pipe until the end of the tapping time. Likewise, the intake of oxygen or nitrogen should be avoided as far as possible.
- the design of the tapping pipe should be such that, regardless of its wear (within technically acceptable limits), a largely uniform mass flow can be transported along the tapping pipe. According to DE 42 08 520 C2, the flow profile of a melt can be determined from the following formula:
- the respective bath height (height of the melt above the outlet end of the tapping tube).
- the required radius of a circular cross-section of the tapping pipe passage is plotted against distance from the outlet end, where "0" defines the outlet end of the tapping pipe, 1.35 meters is the total length of the (new) tapping pipe and maximum bath height
- the effective maximum height of the molten bath above the tapping inlet is 1.35 meters
- the remaining curves show the theoretically minimum radius of the tapping channel at different distances from the outlet end for different bath heights under de r Acceptance of the same cross-section (radius 65 mm) at the outlet end
- a radius of 80 millimeters is sufficient for the cross section of the passage channel to completely fill a circular cross section of the tapping pipe at the outlet end with a radius of 65 mm with the melt jet. If, however, the bath level continues to drop, for example to a minimum bath height of 1,600 millimeters (effective height of the molten bath above the tap inlet now 250 mm), then the same cross section of the tap tube results in the necessary radius of the cross section of the passage channel at the outlet end in the inlet area of the tapping pipe a value of approx. 1 10mm.
- the invention leads to completely different geometries of the passage channel of a tapping tube.
- Fig. 2 shows as a curve (1) again at a bath height of 1600 mm and a radius of the outlet cross section of 65 mm required profile of the outlet channel in longitudinal section (theoretically at least necessary radius).
- Curve (2) shows the flow conditions in a tapping tube according to the prior art (radius of the inlet cross section: 80 mm).
- the avoidance of turbulence and maintenance of a compact jet in the tapping channel solves the invention by such a design of the tapping channel that during the tapping time, so even at low bath heights (effective height of the bath level above the inlet end of the tapping tube: less than 30% of the maximum height) , the entire tapping channel is completely filled with melt.
- the invention comprises in its most general embodiment a tapping tube for a metallurgical melting vessel, whose axially extending passage channel between the outlet end and the inlet end has a channel cross-section A (y) with the following dependence:
- a (y) A. (h, + hk ) / (h, + hk -y) '
- H should be less than or equal to 0.3 times the maximum height (h max ) of a melt in the melting vessel in the axial extension of the tapping pipe
- the variable factor (hi / h max ) takes into account the different flow behavior especially at low bath height.
- the factor " ⁇ 0.3” indicates that a condition is detected in which the effective height of the melt level above the inlet end of the tapping tube is at least 70% less than the effective height of the melt level at the maximum bath height.
- H k represents the existing length of the tapping pipe between the inlet end and the outlet end. While the outlet end of the tapping pipe is necessarily its lower free end and remains unchanged over time, the position of the inlet end changes with the time of use of the tapping pipe By definition, the inlet end corresponds to the level of the adjacent refractory material of a refractory lining of the metallurgical melting vessel, and as the erosion progresses, the length of the tapping pipe is shortened accordingly.
- h length of the tapping tube between inlet end and outlet end
- y axial distance between the outlet end and a location along the tapping pipe.
- the diameter "d" at the outlet end was set at 0.13 meters to ensure a desired flow rate "X".
- the diameter of the passage channel in the inlet area to 0, 19 meters and calculated in 1 meter height to the outlet end to 0, 16 meters.
- the factor (hi / h max) assumed to be> 0.05 and / or ⁇ 0.3 is (h max is the maximum height of the melt in the melting vessel above the inlet region of the tapping pipe in axial extension of the tapping pipe).
- the value is between> 0, 1 and / or ⁇ 0.2.
- the dimensioning of the tapping pipe in the inlet part is particularly important.
- the conditions at low effective heights of the bath level are decisive.
- the cross-sectional geometry at the outlet end is mainly determined by the setpoint of the flow rate (mass flow at maximum bath height).
- the cross-sectional calculation for the passageway refers to values "y"> 50% of the total length of the tapping pipe. "According to another embodiment, these values are increased to ranges> 70%, which means that essentially the inlet half and the inlet side, respectively One third of the total length of the tube should be designed fiction-specific.
- this section can be formed continuously conically tapered; but the necessary taper in the direction of the outlet end can also be done stepwise if necessary.
- FIGS. 3-5 also show technically adapted step-shaped wall profiles with which the desired effects can likewise be realized and which are technically easier to produce.
- the lower outlet side half of the tapping tube, the taper of the follow (upper) inlet-side part but it is also possible to form this part with less conicity (slope), up to a cylindrical shape of the passage channel. This is especially true for the last 10 to 20% of the length of the tapping tube on the outlet side.
- the invention according to one embodiment (circular channel cross-section and symmetrical design of the inner contour to the channel axis) teaches the wall area to be designed such that the slope (S) follows the inner contour of the passage channel (in longitudinal section) as follows:
- the slope S in this case describes the change of the radius ) of a circular cross-section of the tapping channel as a function of the distance y from the outlet end of the tapping.
- h k 0.75 m (eg reduced tapping length with worn converter lining)
- the values should be> 0.02. With very low effective bath heights and shorter tap lengths, the area where S> 0.02 should be, already extends to the inlet half of the tapping channel. This value S can be increased to> 0.025,> 0.05 or> 0.25.
- the value may be »0.25, for example 1, 5, 10, 30, 50, 70 or 100. If the course of the wall of the tapping channel is completely or partially step-shaped or existing accordingly Production plants approximated so "slope" means the slope of the straight in the longitudinal section between the edges successive stages connectable straight line.
- the dimensioning according to the invention of a tapping pipe also takes into account the change in length of the tapping pipe depending on the state of wear of the adjacent lining in that the respective values for the tapping length and the height of the overlying melt are included in the calculation.
- SA (y) change of the cross section in m 2 / m at the point y
- A cross-sectional area of the through-channel at the discharge end of the tapping pipe
- hi 0.3 h max or less of the maximum height (h max ) of a melt in the melting vessel above the tapping inlet in the axial extension of the tapping pipe
- hk length of the tapping pipe between inlet end and outlet end
- y axial distance between the outlet end and a point along the tapping tube.
- the cross-sectional area must increase by at least 47% per meter of channel length in order to create fluid-favorable conditions.
- the inventive design of the tapping tube makes it possible to operate the tapping even at low bath heights with reduced turbulence and continuous melt flow and thus significantly reduce the entrainment of slag.
- by reducing the temperature losses and the reduced wear further economic benefits such as energy savings and extended life of tapping.
