1 前盲从60年代初期至70年代后期,国外发展了一种连续铸钢的新技术,即水平连铸。水平连铸技术具有以下特点: (1)铸机设备高度低,因此无需建高大厂房,该技术特别适用于中、小型炼钢车间,也适用于老钢厂的铸锭车间改造。 (2)铸机设备结构较简单,设备重量比弧形连铸机少40％,故基建投资较少;又由于水平放置,因此便于安装和维修。 (3)水平连铸中间包与结晶器连成一个整体,避免了钢水的二次氧化,因而,连铸坯的纯洁度较高,可铸钢种范围较大。 (4)与弧形连铸相比,水平连铸结晶器内的钢水静压力较高,凝固坯壳与结晶器
A pre-blind From the early 1960s to the late 1970s, a new continuous casting technology developed abroad, namely horizontal continuous casting. Horizontal continuous casting technology has the following characteristics: (1) Caster equipment, low height, so no need to build tall plants, the technology is particularly suitable for medium and small steelmaking plant, also applied to the transformation of the old steel plant ingot. (2) Caster equipment structure is simpler, equipment weight less than the arc caster 40%, so less capital investment; but also because of horizontal placement, so easy to install and repair. (3) The horizontal continuous casting tundish is connected with the mold as a whole to avoid the secondary oxidation of the molten steel. Therefore, the purity of the continuous casting slab is high, and the range of castable steel is large. (4) compared with the arc continuous casting, horizontal continuous casting mold higher static pressure molten steel, solidified shell and mold
