3、提煉鐵的歷史可以追溯到史前時期。古時候,鐵礦石是在炭火中加熱的(起初無疑是偶然的),當(dāng)火熄滅時,像海綿一樣的固體鐵塊就產(chǎn)生了。海綿鐵能夠錘打成型制造工具和武器。冶金前輩發(fā)現(xiàn),在吹火或扇風(fēng)時,火會燃燒得更旺,鐵就會更快地?zé)挸?。從此以后人們就使用風(fēng)箱來增加風(fēng)量。Background Information電弧爐煉鋼圖1 平爐生產(chǎn)示意圖Text Worldwide, the iron and steel industry is one of the most significant and, in terms of tradition, one of the oldest sectors of in
4、dustry. As early as 3,000 years ago, iron was serving as a basis of human culture and civilization. Text The beginning of the extraction of iron from its ores dates back to prehistoric times. In early times, iron ore was heated in a charcoal fire (doubtless by chance at first). When the fire went ou
5、t, a piece of solid iron like a sponge was left. The spongy iron could be hammered into shape to make tools and weapons. Our metallurgical forefathers found that when they blew or fanned the flames, the fire became hotter and the iron was produced more rapidly, so bellows were used to increase the s
6、upply of air. The development of modern ironmaking production benefits from the application of several important techniques:Text Oxygen steelmaking processes are concerned mainly with the refining of a metallic charge consisting of hot metal (molten pig iron) and scrap through the use of high-purity
7、 oxygen to rapidly produce steel of the desired carbon content and temperature. Various steelmaking fluxes are added during the refining process to reduce the sulphur and phosphorus contents of the metal bath to the desired level. The oxygen top-blown process (LD or LD/AC) is currently the more comm
8、on, but is gradually giving way to combined blowing process in some new plants.Text (1) In 1709, Abraham Darby, a yang man succeeded in smelting iron with coke. This innovation resulted in a steep rise in pig iron production. (2) After the year 1755,steam engines and large electric motor were used a
9、s blast momentum to force more air into the hearth increasing blast volume greatly. (3) In 1828, Nilson adopted the regenerative hot blast stove to heat air for blast furnace , reducing the coke ratio of blast furnace greatly.Text Before the Industrial Revolution, steel was an expensive material, pr
10、oduced in only small quantities for such articles as swords and springs, while structural components were made of cast iron or wrought iron.Text In August 1856, an Englishman, Henry Bessemer, made public the description of a process which eventually reduced the price of steel to about a seventh of i
11、ts former cost and more important still, made it possible to produce steel in large quantities. Henry Bessemers process consisted in blowing air from the bottom through the hot metal so that it could burn away impurities. This process was a mainstay of the steel industry. Text The first Bessemer con
12、verter was lined with silica bricks .The acid Bessemer process, as the Victorian ironmasters discovered, could not eliminate phosphor, which is harmful to steel, so low phosphoric pig irons had to be used. In 1878, two Englishmen, Sidney Thomas and Percy Gilchrist, contributed the improvement whereb
13、y they lined the converter with basic refractory bricks, containing magnesia or dolomite. Lime was added to the bath to combine with the phosphor and silicon, and thus remove them from the iron in the form of slag containing calcium phosphate and calcium silicate. The basic lining of the converter p
14、rovided conditions under which the reactions with the lime could take place without destroying the furnace lining. If silica brick were used, as in the acid process, the lime would attack it chemically.Text In 1865, another efficient process for steelmaking was introduced, this transformed the pig i
15、ron and/or scrap into regeneratively heated hearth-type furnace. After its inventors, it was also known as the Siemens-Martin process (or open hearth process). The Siemems-Martin open-hearth furnace was so called because the molten metal lies in a comparatively shallow pool on the furnace bottom or
16、hearth as fig1-1 show. This rather inefficient performance of the open-hearth compared with the enormous output of the blast furnace, justified the emergence of the highly productive oxygen process for steel. Text As soon as electric energy could be supplied in sufficient quantities, electric heat w
17、as used for steelmaking. The electric-arc furnace process was first used extensively for the production of alloy steels during the 19141918 war. The rapid increases in demand for alloy steels during and after the Second World War led to the construction of larger furnace with lower power consumption
18、 per ton of metal. Today, Electric arc furnace has a firm footing in the industry. Text After 1970s, Bessemer process and open-hearth process are losing their significance. As the demand for high quality steels increased, post-treatment became a routine step in the production of steel.Fig.1-1 Open-h

33、叫亨利貝塞麥的英國人公布了他的煉鋼方法,這個工藝能夠把鋼的成本降低到原來成本的七分之一左右,更重要的是它能夠大量地生產(chǎn)鋼了。亨利貝塞麥工藝是從爐底向鐵水吹入空氣,使鐵水中的雜質(zhì)去除,它曾經(jīng)是煉鋼工業(yè)的一個主要支柱。 最早的亨利貝塞麥轉(zhuǎn)爐是用硅磚做爐襯。維多利亞女王時代的鐵器制造商發(fā)現(xiàn),酸性貝塞麥工藝不能去除對鋼有害的磷,所以必須用低磷生鐵進(jìn)行冶煉。1878年,名叫希德尼托馬斯和珀西克利斯特的兩個英國人對此法進(jìn)行了改進(jìn),他們用含氧化鎂或白云石的堿性耐火磚砌成爐襯,再向熔池加入石灰使其與鐵水中的磷和硅化合,這樣磷和硅就以磷酸鈣和硅酸鈣的形式從鐵水中除去。轉(zhuǎn)爐采用堿性爐襯提供了鐵水與石灰發(fā)生反應(yīng)的條
34、件,從而避免了爐襯的損壞。如果象酸性法那樣使用硅磚,石灰就會對爐襯產(chǎn)生化學(xué)侵蝕作用 Translation在1865年,誕生了另一種有效的煉鋼工藝,它使生鐵/和廢鋼進(jìn)入到具有蓄熱室的爐子中進(jìn)行冶煉。依發(fā)明者的名字命名,就叫做西門子馬丁工藝(平爐工藝)。之所以被叫做西門子馬丁平爐工藝是因?yàn)殍F水盛在一個比較淺的爐底或爐膛內(nèi),如圖1-1所示。但是,平爐效率不高,適應(yīng)不了高爐的巨大生產(chǎn)能力,這就必然促成了大生產(chǎn)能力的氧氣轉(zhuǎn)爐煉鋼法的出現(xiàn)。Translation一旦電能供應(yīng)充足,電熱就開始被用來煉鋼。在19141918年的戰(zhàn)爭期間,電弧爐工藝首次被廣泛地用于合金鋼的生產(chǎn). 二次大戰(zhàn)期間和之后,合金鋼需求
35、的快速增加導(dǎo)致要建造爐容大和噸鋼能耗低的爐子。當(dāng)前,電弧爐在工業(yè)上有著穩(wěn)定的地位。 二十世紀(jì)七十年代后,亨利.貝塞麥工藝和平爐工藝逐漸被淘汰。而隨著對高質(zhì)量鋼需求的增加,爐外精煉已成為當(dāng)今煉鋼過程中必不可少的步驟。Translate the following expressions into English keys 1. the iron and steel industry 2. spongy iron 3. structural component 4. basic refractory brick 5. wrought iron 6 . open hearth 7.
