Description

(54) ГАЗОКИСЛОРОДНАЯ ФУРМА(54) OXYGEN SOURCE

Изобретение относитс  к металлургии , в частности,к сталеплавильному производству. Известны фурмы дл  продувки и нагрева жидкого металла в сталеплавиль ной ванне 1. Наиболее близкой по технической сущности и достигаемому результату к предлагаемой  вл етс  газокислородна  фурма дл  нагрева и продувки жидкого металла, содержаща  концентрично расположенньае трубы, образующие тракты дл  подвода кислорода и газа, подвода и отвода охлаждающей воды, и головку с соплами 21,-, Недостатком известного устройства  вл етс  невозможность утилизации тепла отход щих газов. Цель изобре.тени  - повышение тем пературы факела и утилизаци  тепла отход щих газов. Поставленна  цель достигаетс  те что газокислородна  фурма дл  нагре ва и продувки жидкого металла, состо ща  из концентрично расположенны тру-б, образующих тракты дл  подвода и отвода .охлаждающей воды, подвода кислорода и газа, и головки с сопла ми, снабжена камёрой нагрева, установленной на внутренней поверхности наружной трубы со встроенными в нее распылительными форсунками и сообщенной с трактом дл  подачи газа посредством- каналов. Кроме того, распылительные форсунки снабжены обратными клапанами. На чертеже представлена газокислородна  фурма с камерой нагрева, продольный разрез. Фурма состоит из трубопровода 1 подвода кислорода, трубопровода 2 подвода охлаждающей воды, трубопровода 3 подвода газа, трубопровода 4 отвода охлаждающей воды. Камера 5 нагрева состоит из трубок 6 подвода и отвода газа, распылительных форсунок 7, нагреваемой поверхности 8. Форсунка 7 снабжена обратным клапаном 9, установленным в корпусе 10 на пружине 11. В корпусе 10 выполнены отверсти  12 дл  провода воды. В головке фурмы выполнено сопло 13 смешени . фурма работает следующим образом. При вхождении камеры 5 нагрева в зону высоких темп ератур (1700-1800 С) через нагреваемую поверхность 8 камеры 5 проходит поток тепла с нагреванием внутреннего объема камеры до 100Ь-1200С.The invention relates to metallurgy, in particular, to steelmaking. Known tuyeres for purging and heating a liquid metal in a steel-smelting bath 1. The most close to the technical essence and the achieved result to the proposed is an oxygen-oxygen tuyere for heating and purging a liquid metal, containing concentrically located pipes forming paths for oxygen and gas supply, supply and removal of cooling water, and a head with nozzles 21, -. A disadvantage of the known device is the impossibility of recovering the heat of the exhaust gases. The aim of the invention is to increase the temperature of the flare and utilize the heat of the exhaust gases. This goal is achieved by the fact that a gas-oxygen lance for heating and blowing liquid metal, consisting of concentrically arranged pipes, forming paths for supplying and discharging cooling water, supplying oxygen and gas, and a head with nozzles, is equipped with a heating chamber installed on the inner surface of the outer tube with spray nozzles embedded in it and in communication with the path for gas supply through channels. In addition, the spray nozzles are equipped with check valves. The drawing shows a gas-oxygen lance with a heating chamber, a longitudinal section. The lance consists of pipeline 1 for supplying oxygen, pipeline 2 for supplying cooling water, pipeline 3 for supplying gas, pipeline 4 for discharging cooling water. Heating chamber 5 consists of gas supply and exhaust pipes 6, spray nozzles 7, heated surface 8. Nozzle 7 is equipped with a check valve 9 installed in housing 10 on spring 11. Holes 12 are provided in housing 10 for the water wire. A mixing nozzle 13 is formed in the head of the lance. lance works as follows. When the heating chamber 5 enters the high temperature zone (1700-1800 C), the heat flux passes through the heated surface 8 of the chamber 5 and heats the internal volume of the chamber to 100–200 ° C.

A known gas-oxygen lance for blowing melts with preliminary mixing of gases ( fuel and oxygen), which consists of coaxially arranged pipes and a head with nozzles with a central supply of cooling water. However, this lance is not equipped with a device that prevents flame from leaking from the nozzles to the mixing unit. Combustion of a mixture of gas and oxygen inside the annular supply path leads to cut In the proposed gas-oxygen tuyere, in order to prevent flame penetration from the purge nozzles into the fuel-oxygen path, the latter in the lower part is divided by an annular water-cooled partition with openings (an annular partition is manufactured metal, for example copper), an annular gas manifold is placed under the partition, which communicates with the purge nozzles. FIG. 1 shows the gas-oxygen |) urma in section; in fig. 2 is the same; the section along A — A in FIG. 1. The described lance consists of three coaxial alipulations of the pipes, through which, like in an ordinary oxygen lance, the head I is fed, and water is drained from it, and purging gas is fed into it. The lance has a central-axial supply of water 2 to the head I 5 for cooling, channels 3 for draining water from the cetiral cavity of the head into the inter-pipe cavity 4 of the lance. Channels 3 are evenly distributed between the nozzles 5. In the tail part of the tuyere, as in the known tuyeres, there are 10 nozzles b and 7, respectively, for iodachi in the tuyere and removal of water for cooling from it, as well as the nozzles 8 and 9, respectively, for introducing oxygen into the tuyere and fuel (gas). In addition, in the tail part of the tuyere, at the 15th level of the tubing 9, there is a mixing ring 10, which overlaps the annular gap formed by the central (axial) pipe 11 and the separation pipe 12. The mixing ring 10 is sealed 20 (for example, by welding), welded or with one of these pipes or with both. In the first case, the circumferential docking with the pipe has a seal 13. The mixing ring 10 contains a series of vertical holes — mixing nozzles 14, through which from the upper part 15 of the annular gap, blocked by ring 10, oxygen passes into the fuel-oxygen path 16. The mixing nozzles 14 in the lower part are articulated with openings 17, which serve to supply gaseous
