连续铸钢是在炼钢和轧钢生产之间发展出来的一种全新的生产工艺,是钢铁工业上继氧气炼钢之后的又一重大新技术,它的出现使得铸锭和轧制溶为一体。因而它与传统的模铸技术相比,有很多的优点,连续铸钢技术从五十年代发展起来后,已几经改革,最显著的改革是高度的降低。第一代立式连铸机高度30米以上,第二代立弯式连铸机高度20米左右,第三代弧型连铸机高度10米左右,目前从工艺技术上讲以弧型连铸机最为成熟,也是最流行的一个机型,但这种弧型连铸机也有它的弱点,首先是设备不能安装在一般的炼钢厂厂房中,而要建造较高的厂房,另外弧形连铸机浇<80mm的方坯时结晶器液面高度控制较困难,由此带来了一些问题需要解决,为发展连续铸钢技术,开发了一种新的连铸技术,即水平连铸技术。因此有资料称它是连铸机的未来。
Continuous casting is a new production process developed between steelmaking and rolling production. It is another major new technology in the steel industry following oxygen steelmaking. Its appearance makes the integration of ingot and rolling . Therefore, it has many advantages compared with the traditional molding technology. After the continuous casting technology developed from the 1950s, it has been reform several times and the most significant reform is highly reduced. The first generation of vertical caster height of 30 meters, the second generation of vertical caster height of about 20 meters, the third generation of arc caster height of about 10 meters, from the current technology to speak with Arc The most mature casting machine, but also the most popular model, but this arc-type caster also has its weaknesses, first of all equipment can not be installed in the general steelworks plant, but to build a higher plant, the other arc Shape continuous casting machine billet <80mm billet mold height control more difficult, which brought some problems to be solved, in order to develop continuous casting technology, has developed a new continuous casting technology, which even the level of even Casting technology. So there is information that it is the future of caster.
