  tundish
Numerical simulation of flow phenomena and optimum operation of tundish
      
The results show that the configuration and operation of tundish play an important part in quality assurance of grade 20 carbon-steel products.
      
Strict control of the superheat degree of casting liquid steel can decrease the non-metallic inclusion content of the re-oxidation in billets and reduce the erosion of tundish.
      
The design of a tundish to improve the efficiency of inclusion removal requires a detailed knowledge of the flow behavior of the molten steel in the tundish.

Studies were carried out by hydraulic modeling on flow morphology and particle floatation behaviour conducted by different modes of dams built inside the continuous casting tundish, among which the dual dam is beneficial to the purification of molten steel. Results from productive application of tundishes with such a type of dam are consistent well with those of the hydraulic tests. Compared with those incorporating only one single dam, the oxide inclusions in the concast slabs can be reduced at least...

Studies were carried out by hydraulic modeling on flow morphology and particle floatation behaviour conducted by different modes of dams built inside the continuous casting tundish, among which the dual dam is beneficial to the purification of molten steel. Results from productive application of tundishes with such a type of dam are consistent well with those of the hydraulic tests. Compared with those incorporating only one single dam, the oxide inclusions in the concast slabs can be reduced at least one grade, while slab reject rate caused by inclusions reduced by 1/3 to 1/2.

用水力模型研究了中间包内不同隔墙时的流股形态和粒子上浮,表明双隔墙(底部中孔隔墙前加矮墙)是有利于净化钢液的较好隔墙形式。双隔墙中间包的生产考核取得与水模试验一致的结果。与单隔墙中间包比较,连铸坯中氧化物夹杂可降低1级以上,轧后夹杂废品率减少1/3~1/2。

The tundish is the important metallurgical unit of the continuous castin-g. In order to incressing demand for steel of higher quality, effective mesur-es must be elaborated to remove the large non-metallic inclusions by optimizing fluid flow and renewal time of liquid steel in the tundish, making it possible to raise from steel melts.The paper presented the influence of liquid debit, teeming spout immer-sed in bath, deep bath, proper dam on the fluid renewal time and flow pattern in the tundish...

Liquid depth and proper dam of tundish are very effective for renewal time and flow pattern in the tundish.

中间包是钢水流入结晶器的最后一个冶金容器,它对铸坯质量有重大影响。为减少铸坯中的夹杂物,必须改善钢水在中间包内的停留时间分布和流动状态,使夹杂物充分上浮分离。 本文用水力学模型和光电示踪法,研究了中间包流量、液面高度、挡墙形式和钢流注入方式等对平均停留时间和流动状态的影响,指出了中间包液面高度对平均停留时间影响最为显著,而挡墙的作用在于改善了钢水流动的轨迹。

An investigation has been carried out into the "metallurgical criterion" of the slab solidification during continuous casting. The effect of following variables on the metallurgical criterion has been studied by the mathematical model of heat transfer: casting speed, spray water intensity, water distribution in spray zone, superheat in tundish, convection in liquid pool and temperature of spray water. Considering these factors, a nomogram of the productivity related to slab thickness, casting speed, spray...

An investigation has been carried out into the "metallurgical criterion" of the slab solidification during continuous casting. The effect of following variables on the metallurgical criterion has been studied by the mathematical model of heat transfer: casting speed, spray water intensity, water distribution in spray zone, superheat in tundish, convection in liquid pool and temperature of spray water. Considering these factors, a nomogram of the productivity related to slab thickness, casting speed, spray water intensity and depth of liquid pool was prepared so as to selecte reasonably the technological parameters and to control scientifically the operation.

本文论述了连铸坯凝固冷却过程的“冶金标准”。用数学模型从理论上计算了操作参数如拉速、比水量、二冷区水量分布、钢水过热度、液相穴内钢水对流运动和二冷水温度等对连铸坯凝固“冶金标准”的影响。根据计算结果,整理出坯厚、拉速、比水量、液相穴深度和生产率的关系图,这有利于选择合理工艺参数,科学地控制操作。
