(54) CONVERTER FOR LABORATORY SLOTS

 ... one -.

 The invention relates to metallurgy, in particular, to devices for studying parameters of metallurgical processes .., ..:

A known converter for laboratory 5 studies containing a refractory lining and; the cooled body, in which the lining is made monolithic, and the body itself is made of bimetallic material with a Fusible layer adjacent to the shell, and is equipped with a ring electric inductor P.

The closest in technical essence and attainable results of the invention is a converter 5 for laboratory purposes, comprising a body with a refractory lining and a removable bottom, into the wall of which a quartz plate 2 is inserted.

V ...... V 20,. The disadvantage of the converter is a single flat surface (5-surface observation of boundary sections both in diameter and depth of penetration of the SWe-25 oxidative flow of the melt, and it is not possible to set the flow of the process in the horizontal T volume in the horizontal or in the Vertical planes of the cross section, and in particular, conduct, nairimer, with Yes;

The purpose of the invention is to provide a more i accurate study of the duo eto mode lb ho-.

Delivered - 1) LB is achieved by the fact that the converter is equipped with a refractory first-egorodka, replicated in the lower part of the body under the bottom of m and plate-screen, made of low-melting material and installed under the partition wall in the grooves, filled around the perimeter of the bottom. - :; -.

In the drawing dredstavlenb proposed.

device., .. ::. (Converter contains, case 1 with refractory lining 2, removable bottom 5. In the refractory lining of the case there is: a special groove - sweat, made around the entire perimeter, to install the refractory partition 4 (refractory:. Plate of sufficient thickness and strength with. Aim, ensuring the optimal exposure of the diyMaic and EC loadings of the melt metal of the Blended metal). In addition, it has a sufficient refractory resistance when in contact with aggressive ions and radiation formed in the process P1 of the blower. i

lpegopodka - is installed on the refractory mass (magnesite powder with:

by adding liquid glass) to seal the “artificial: bottoms. The removable bottom 3 bore a similar groove - sweat; along the entire perimeter for (the upper layer of the screen 5, at the same time, to achieve; to the body with clamps; 5 around the perimeter. Their number is chosen arbitrarily, based on the strength conditions of the fixing clamps to the body. . e. Screen 5, located in: close proximity to Chaga purge, not in contact with the liquid van Yüyü, will allow you to evaluate the transferred temperature of Screen 5 due to the transfer of the heat flow wasp. material into separate qi, smelt melt.; The device works as follows: -,;; - iB. any studied and interesting period of melting (sample melt for the content of C and Mp is taken during the purge or, the plate-screen 5 is removed and measurements are taken of the printed area "hot n: tna, with

This makes it possible to adjust

 oxidant, (pressure, flow rate) in the bath and the position of the tuyere above the melts. After which a brazen T1Lasti.nu-ec-en-CAN be replaced with a new one. The heating of the partition 4 occurs throughout the whole area evenly (the more “cold sides are located near the vessel walls. At a fixed fixed position — the supply of the tuyere tuyere) and the temperature range, and therefore, the heat flow generated is: fio to the center of the reaction vessel in the subfurm area . The radiating ability of the partition 4 transmits a melt-melting plate-screen 5 to receive a heat flux plate, reflecting the highest and lowest temperature at a given moment of purging. The heat flux regulates the air gap between the partition 4 and the plate I. minimizes when the partition is

, and the plate is in contact. The gap is adjusted, based on the thermal conductivity of the overheating | 1 4 and the screen used; ng1 5. To reduce heat consumption by 5 rgn) to radiate from the partition of 4 in; At the place of junction of day 3, thermal foams are provided, MOTHbie gaskets, shown (shown on the drawing), or clamps are sealed with heat material, for example, cord asbestos.

The experiments were carried out in containers with a diameter of 65.0 mm. The experimentally selected partition 4 was about 7 mm, 0 mm (in this case, the plate was played by the bottom of the container). Trill screen 5, respectively, was 2.0–3.0 mm and in this case used lead. The mass of the blown metal was 1.5 kg; oxidant consumption (oxygen) - on the order of 6, .10 nmCmin with a diameter of nozzle of a tuyere of 4.0 GL «7 -

Thus, the device will give the possibility of MORNING ® dry; adjust the rto to blow 5 adjustment of the blast mode in order to reduce metal carbon, tem most likely to stabilize the process of producing carbon by optimizing oxidation of carbon and that eventually improving the slagging process and thermal conditions of smelting. -, ---, - х
