(54) УСТРСЙ1СТВО ДЛЯ ОТВОДА ДЫМОВЫХ ГАЗОВ ПРИ ТОРКРЕТИРОВАНИИ ФУТЕРОВКИ(54) DEVICE FOR DRAINING OF SMOKE GAS WHEN TREATING THE LIGHTING

Изобретение относитс к мёталлур-, гии, а конкретнее к вспбмогательному оборудованию конверте)ного прризводства стали.The invention relates to metallore, hygiene, and more specifically to the support equipment of an envelope for steel production.

Известно устройство, содержащее водоохлажд емый камин,.кислородную фурму и желоб дл подачи сыпучих матери:алрв, размещенные на тележке, перемещаемой вдоль конвертера и отъезжаинцей от горловины при .отборе проб и скачкзанк шлака } A device containing a water-cooled fireplace, an oxygen tuyere and a chute for feeding bulk mothers: alrvs, placed on a trolley moved along the converter and departing from the neck during sampling and a slag slag} is known.

Наиболее близким к предлагаемому вл етс устройство дл отвода дыма при торкретировании, содержащее прич ставной камин дл отвода продуктов горени в основной охлаждаемый кессон конвертера 2 .Closest to the present invention is a device for removal of smoke during gunning, which contains a stacked fireplace for removal of combustion products to the main cooled coffer of the converter 2.

;Недостатком известного устройства ч1П етс его низка надежность,, что определ етс значительным рассто нием камина от горловины конвертера при торкретировании до кессона .вверху , следовательно, большим подсосом окружающего воздуха и затоплением отсасываемой струи. КрогЛе того, в результате избыточного давлени газов перед отверстием дл ввода хобоТа машины с фурмой больша газов устремитс по пути наименьшеКОНВЕРТЕРА: A disadvantage of the known device is its low reliability, which is determined by the considerable distance of the fireplace from the converter throat when gunned to the caisson at the top, consequently, by a large suction of ambient air and flooding of the suction jet. In addition, as a result of the overpressure of the gases in front of the hole for the entry of the machine with the tuyere, the larger gases rush along the path of the smallest CONVERTER:

го сопротивлени , т.е. через это отверстие на рабочую площадку.His resistance, i.e. through this hole to the working platform.

НедоЙтатком устройства бл етс также его низка маневренность.A low maneuverability is also deficient in the device.

Claims

779400 gasdynamic protection of an embrasure 4. To protect the device of the set of heatgun TygaLuchsH installed a water-cooling shield 8 and 9. ,,,., .. ",:,., -, -, .-" The following Step Fireplace 1 is installed in the working position. Shotfurm 5 is inserted into the converter. After switching on the kislbrod and feeding the vial Bi to the converter, fuel combustion begins, the gunning mass is sintering on the masonry, and the smoke under the action rarely goes to the scrubber for cooling and cleaning. The process of ropKepTripOBaSHk torc & tuyere 5 is removed from the envelope, the machine takes the place of Hai in the workshop located outside the converters. The smoke evacuator is removed from the converter for a certain distance (100-150 mm) and acts until the summer of preparing the latter and breaking the lining. Samples are taken through the embrasure 4 and the temperatures of the liquid steel are carried out. The proposed device possesses high maneuverability and reliability of Sac4ieT providing the possibility of moving the side fireplace and adjusting the gap between the fireplace and the converter; and by reducing the leakage of air through the leakiness of the fireplace and its joints with the converter and the gas outlet path of the converter, Claim 1. Device for flue gas removal during shotcrete of the converter lining, containing a lined added fireplace with a flue gas duct to connect the gas outlet with a gas outlet the converter path and the embrasure for the gunning tuyere, which is so that, in order to improve the maneuver and reliability of the device, it is equipped with a self-propelled trolley mounted on the metal The constructions of the workshop are movable along and perpendicularly to the KOHfiepTepoB line, and the fireplace is suspended on a trolley and is made with a gas-dynamic embrasure protection. . 2. The device according to claim 1, wherein the fireplace is filled with water cooled. . Sources of information taken into account in the examination 1.Lapitsky V.I. and others.
