Feed tank injection: injection volume of the tank showed that the lower limit of coal, to allow automatic feeding signal injection tank pressure settings to reach the middle tank full feed。 string injection cans and cans of injection。再后簡(jiǎn)要介紹了幾種新噴煤工藝，包括： 富氧大噴煤 量技術(shù) ； 利 用 等離子大量噴吹煤粉； 復(fù)合噴吹 技術(shù)； 粒 煤噴吹技術(shù) 。摘 要 I 摘 要 本次畢業(yè)設(shè)計(jì) 主要闡述了高爐噴煤噴吹自動(dòng)化控制系統(tǒng)，不包括制粉過(guò)程的控制，控制范圍是從煤粉倉(cāng)、中間罐、噴吹罐、噴吹總管、由爐前煤粉分配器到噴吹支管的自動(dòng)控制過(guò)程。 簡(jiǎn)介描述了 幾種較成熟的工業(yè)性生產(chǎn)流程 ： 德國(guó)KvTTNER流程 ； 美國(guó)阿姆科 (ARMCO)流程 ； 日本住友流程 ； 日本川崎流程 ； 盧森堡 Paul Wurth流程 ； 混合型流程 ； 7 英鋼聯(lián)粒煤噴吹流程 。s, Europe, China, the United States before some of the factory started in the blast furnace pulverized coal injection on the test. 7O at the end of the second oil crisis in the emergence of the blast furnace pulverized coal injection technology to speed up research and development, especially in Europe and Japan is in the practical application has been made a major breakthrough. Foreword to the first part of the definition of a blast furnace pulverized coal injection is from the blast furnace tuyere direct injection to the ground of the coal (anthracite, bituminous coal, or both, as well as a mixture of pulverized lignite), to replace the coke to the blast furnace to provide heat and reducing agent. Led by the definition of the meaning of the use of this technology, it replaces the lowcost coal and increasingly scarce expensive metallurgical coke, coking reduced so that the cost of blast furnace substantially reduced. It is a means of regulating the status of furnace, but also work to improve the hearth, Detailed Summary VI and is stable antegrade blast. And then introduced the basic process technology used, under the milling device to the distance from the blast furnace, coal stores, injection tank placement differences in the thickness pipeline injection, injection pressure is high or low concentrations of the size of transmission as well as different forms of spray, you can have a direct injection, indirect injection。s outlook for blast furnace. The second most of the major coal injection on blast furnace automation control package. First point of injection and detection process carried out on the layout, including the choice of three cans of string emission requirements can injection valve, fluid valve, charge pressure valve are pressure valves, fire nitrogen valve, conical valve under , Detailed Summary VII the cone valve, under the coal feeder and the distribution of the ball valve were pared and described in detail on the installation drawings indicate the location, but also all the necessary measuring equipment (such as pressure, temperature, weight, gas content, etc.) , the required number, a description of the installation location. And then in the graph on the basis of the control process described injection. First introduced the basic mode of operation: fully automatic operation, manual operation, and maintenance operations, and then is a major operation carried out by Overview (including coal from the coal inverted position to the intermediate tank can control, to the pulverized coal injection in the middle tank cans cans back control from the injection of pulverized coal to blast furnace tuyere spray cans of control, stop the blast furnace pulverized coal injection control, security control procedures for the chain), and finally a detailed description of the specific operation. Tank feeding the middle: the middle of the preconditions can feed tank for the middle must be an empty signal, the pressure must be less than , emission valves in the open status, filling pressure valve, fluid valve, cone valve and the valve under the cone in the off state, intermediate between the cans and the cans are injection valve in the off state。 。寶鋼 1高爐噴煤即屬阿姆科流程。 1 前言 4 富氧大噴煤量技 術(shù) 高爐鼓風(fēng)中含氧每增加 1％ ， 可增產(chǎn) 3％ ，可多噴煤 8～ lOkg／ t。斯肯索普廠噴吹的粒煤粒 度 95％雖小于 2 mm，但只有 10％ ～ 3O％小于 74μ m， 其三座高爐通常噴煤量為 150kg／ t。噴煤比也持續(xù)上升，重點(diǎn)企業(yè)平均噴煤比 大 于60千克／噸鐵。但我國(guó)高爐尚無(wú)專用氧氣機(jī)，使用煉鋼親氧常常得不到保證 ， 致使噴煤量不可能達(dá)到 150～ 200千克／噸鐵；原燃精條件差 ， 不利于改善料往透氣性 ， 從而阻礙噴煤量的增加 。 煤粉倉(cāng)下接中間罐，煤粉倉(cāng)與中間罐之間采用軟連接，設(shè)置 1 中間罐上錐形閥。 2 高爐噴煤噴吹自動(dòng)化控制整體方案 11 2． 手動(dòng)操作：出必要的安全操作外，還可以人工的對(duì)個(gè)單體設(shè)備進(jìn)行手動(dòng)操作。 2） 噴吹罐內(nèi)壓力達(dá)到設(shè)定值。正確的回波信號(hào)識(shí)別由智能軟件完成，精度可達(dá)到毫米級(jí)。 使產(chǎn)品使用更方便 ,更可靠。3mm 特性與優(yōu)勢(shì)： 無(wú)盲區(qū)，高精度 兩線制技術(shù)，是差壓儀表、磁致伸縮、射頻導(dǎo)納、磁翻板儀表的優(yōu)良替代產(chǎn)品。 6） 中間罐與噴吹罐之間的均壓閥處于“關(guān)閉”狀態(tài)。噴吹總管
