Description

but

Filled in the form of a refractory tube, it is tentatively ready for operation. To the top of the vfeTa nnqecKoft part of the wiring summed up the inert or neutral gas. Creating Excess -. gas pressure in the south in the cavity of the conduction of the exhaust gas from it slag.j

A portion of 10–50 i of the required quantities of the element is deposited on the surface of the metal in the wiring; they are kept for 1/30 I for 9 min to dissolve 30–70% of the element; Ment in the metal filling the cavity of the tipd-vodka creates in it an overpressure of 1 0, O5-2 atm of gas for 0, O1-1 min, due to j outside which the residual portions and the metal with the solution ijieifflbiM element come from the cavity to; | 5 Lubin O, O5-O, 5 metal height. This obes-4 PacTBo mie almost complete element in metal is ignored. Then, the gas pressure in the wiring is reduced due to the joint of its cavity with the atmosphere, the Metal again enters the cavity of the refractory part of the wiring. At the end of the entry operation, the metal is repeated. During the entire period of the element introduction, the metal is mixed with a mixed gas; we feed 1 gm through porous npoq-28 ki to the bottom buckets. The proposed method is especially effective in continuous casting, steel on vertical, radial and curvilinear installations.

At the same time, light-melting and with the best dilution, elements are introduced, for example, alkali, in large portions and withstand: time on the surface, and refractory-1 elements, for example, titanium, tungsten, and portions and withstand I 3S more time

Claims (5)

1. The method of doping, deoxidation and mohifitsirovaniya metals and alloys, concluded by introducing the reagent into the metal and mixing it with an inert gas, is different because, in order to increase the amount of absorption and expansion of the quantity of the elements, the reagent is periodically , in portions of lp-50% of-ofélero, the amount is injected onto the metal surface limited (with a refractory wiring with a neutral gas | b of its cavity, can withstand & -70% of the reagents in the metal to dissolve. I 2. The method according to claim 1, about tl and h ay m and d- “. With this, refractory wiring limit O, O1-O, 5 metal surface. 3. The method according to claim 1, is also distinguished by the fact that the reagent is injected into the deep-i bin corresponding to O, 05-O, 5 of the height of the metal. 4. The method according to claim 1, which means that during the introduction of the reagent into the volume of the metal, an inert gas overpressure is created in the wiring cavity of O, O5-2 atm. 5. A method according to claim 4, characterized in that the overpressure takes about 0.01-1 minutes.
