熱風爐成都收賬科學技術成都找人公司進步,特別是信息和網絡技術成都收賬發展同科研和生產收賬密切結合,提供瞭巨大成都找人公司技術可能性,提高工業電爐熱處理的自動化智能化.利用電熱效應供熱的冶金爐,其電爐設備通常是成套的,包括電爐爐體,開閉器,真空設備,電力設備,自動調節系統,爐用機械設備附屬輔助電器.同燃料爐比較,其電爐的特點有,爐內氣易控制,甚至可透水地坪抽成真空,加熱溫度高,溫度易控制,生產過程實現機械化和自動化的可能性高.
The advances in science and technology of hot-blast stoves, especially the close combination of information and network technology with scientific research and production, provide enormous technical possibilities to improve the automation and intelligence of heat treatment of industrial electric furnaces. Compared with fuel furnaces, the electric furnaces are characterized by easy control of the gas in the furnaces, even vacuum pumping, high heating temperature, easy control of temperature, and high possibility of mechanization and automation of production process.
隨著計算機技術和自動化技術的發展,計算機控制系統廣泛用於工業自動化中,極大地提高瞭工廠裝備的技術水平,促進瞭生產,提高瞭產品質量,保證瞭生產的安全可靠,工業電爐成為瞭工業自動化的一大支柱.當今,新時代需要新的模式,技術與產業信息化,網絡化成為必然.國傢的工業發展度在國民經濟中占著相當重要的位置.20世紀 50年代以來,由於對高級冶金產品需求的增長和電費隨電力工業的發展下降,電爐在冶金爐設備中的額度逐年上升.眾多廠傢生產最多的工業電爐有退火熱風爐,電阻爐,淬火熱風爐,鹽浴爐,箱式熱風爐,井式熱風爐,臺車熱風爐,氣體滲碳熱風爐.
With the development of computer technology and automation technology, computer control system is widely used in industrial automation, which greatly improves the technical level of plant equipment, promotes production, improves product quality and ensures the safety and reliability of production. Industrial electric furnace has become a major pillar of industrial automation. Since the 1950s, the demand for high-grade metallurgical products has increased and electricity charges have declined with the development of electric power industry, so the quota of electric furnace in metallurgical furnace equipment has increased year by year. Many industrial electric stoves are annealing furnace, resistance furnace, quenching furnace, salt bath furnace, box type hot blast furnace, well type hot blast furnace, trolley hot blast furnace, gas carburizing hot blast furnace.
使用方面,在鑄造車間,有熔煉金屬的沖天爐,感應爐,電阻爐,電弧爐,真空爐,平爐,坩堝爐等；有烘烤砂型的砂型幹燥爐,鐵合金烘爐,和鑄件退火爐等；在焊接車間,有焊件的焊前預熱爐和焊後回火爐；在鍛壓車間,有對鋼錠或鋼胚進行鍛前加熱的各種加熱爐；在金屬熱處理車間,有改善工件機械性能的各種退火,正火,淬火和回火的熱處理爐等.工業電爐還廣泛應用於其他的工業,比如,石油工業的蒸餾爐和裂化爐,礦石燒結爐和煉焦爐,矽酸鹽工業的水泥窯和玻璃熔化,冶金工業的金屬熔煉爐,食品工業的烘烤爐,煤氣工業的發生爐等.工業電爐按熱工制度可分為兩大類,分別是間斷式爐又稱周期式爐,和連續式爐.其中,周期式爐的特點在爐子間斷生產時,每一加熱周期內爐溫度是變化的.
In the casting workshop, there are cupolas, induction furnaces, resistance furnaces, electric arc furnaces, vacuum furnaces, open hearth furnaces, crucible furnaces, etc. for smelting metals; sand mold drying furnaces for baking sand molds, iron alloy baking furnaces, and casting annealing furnaces; preheating furnaces for welding parts and tempering furnaces after welding in the welding workshop; ingot or steel embryo feeding in the forging workshop. Various heating furnaces heated before forging; various annealing, normalizing, quenching and tempering furnaces for improving the mechanical properties of workpieces in metal heat treatment workshops. Industrial electric furnaces are also widely used in other indus印花地坪tries, such as distillation and cracking furnaces in the petroleum industry, ore sintering and coking furnaces, cement and glass furnaces in the silicate industry. The industrial electric furnaces can be divided into two categories according to the thermodynamic system: intermittent furnaces, also known as periodic furnaces, and continuous furnaces. The characteristics of periodic furnaces are that the temperature of the furnaces varies in each heating cycle during intermittent production.
