钢铁冶炼钢铁冶炼ironandsteelsmelting钢、铁冶金工艺的总称。工业生产的铁根据含碳量分为生铁(含碳量2%以上)和钢(含碳量低于2%)。基本生产过程是在炼铁炉内把铁矿石炼成生铁,再以生铁为原料,用不同方法炼成钢,再铸成钢锭或连铸坯。铁冶炼现代炼铁绝大部分采用高炉炼铁,个别采用直接还原炼铁法和电炉炼铁法。高炉炼铁是将铁矿石在高炉中还原,熔化炼成生铁,此法操作简便,能耗低,成本低廉,可大量生产。生铁除部分用于铸件外,大部分用作炼钢原料。由于适应高炉冶炼的优质焦炭煤日益短缺,相继出现了不用焦炭而用其他能源的非高炉炼铁法。直接还原炼铁法,是将矿石在固态下用气体或固体还原剂还原,在低于矿石熔化温度下,炼成含有少量杂质元素的固体或半熔融状态的海绵铁、金属化球团或粒铁,作为炼钢原料(也可作高炉炼铁或铸造的原料)。电炉炼铁法,多采用无炉身的还原电炉,可用强度较差的焦炭(或煤、木炭)作还原剂。电炉炼铁的电加热代替部分焦炭,并可用低级焦炭,但耗电量大,只能在电力充足、电价低廉的条件下使用。钢冶炼炼钢主要是以高炉炼成的生铁和直接还原炼铁法炼成的海绵铁以及废钢为原料,用不同的方法炼成钢。主要的炼钢方法有转炉炼钢法、平炉炼钢法、电弧炉炼钢法3类(见钢,转炉,平炉,电弧炉)。以上3种炼钢工艺可满足一般用户对钢质量的要求。为了满足更高质量、更多品种的高级钢,便出现了多种钢水炉外处理(又称炉外精炼)的方法。如吹氩处理、真空脱气、炉外脱硫等,对转炉、平炉、电弧炉炼出的钢水进行附加处理之后,都可以生产高级的钢种。对某些特殊用途,要求特高质量的钢,用炉外处理仍达不到要求,则要用特殊炼钢法炼制。如电渣重熔,是把转炉、平炉、电弧炉等冶炼的钢,铸造或锻压成为电极,通过熔渣电阻热进行二次重熔的精炼工艺;真空冶金,即在低于1个大气压直至超高真空条件下进行的冶金过程,包括金属及合金的冶炼、提纯、精炼、成型和处理。钢液在炼钢炉中冶炼完成之后,必须经盛钢桶(钢包)注入铸模,凝固成一定形状的钢锭或钢坯才能进行再加工。钢锭浇铸可分为上铸法和下铸法。上铸钢锭一般内部结构较好,夹杂物较少,操作费用低;下铸钢锭表面质量良好,但因通过中注管和汤道,使钢中夹杂物增多。近年来,在铸锭方面出现了连续铸钢、压力浇铸和真空浇铸等新技术。
