On the basis of analysis of the measuring results , the reasonable preheating operation regulations are carried out 结合测量结果分析了铸坯加热过程的温度制度和供热制度，提出了加热炉合理的热工制度，并应用于实际生?之中。
In order to get the high - qualitied ingot and stabilize the production during the cc process , we must find the suitable controlling parameters to control it 在钢铁连铸生产过程中，保证质量及生产稳定性的关键在于选择合适的工艺参数以控制铸坯的凝固过程。
The paper put forward a new model and tendency of rolling plate which adopt the medium thickness casting billet and the modern steckel mill 进而指出，中等厚度的连铸坯与现代炉卷轧机组合的成卷轧制中厚板的生产模式，是今后中厚板生产发展的一种新模式和方向。
By the industrial experiment , the distribution of continuous casting billet preheating temperature is measured , and the economic load range of reheating furnace is established 摘要在工业生?条件下测量了铸坯加热温度分布，工业试验确定了加热炉经济负荷运行区。
A new processing technique for seamless tubes manufacture of stainless steel is introduced in the present work , in which die cast hollow blank is directly used for a hot extrusion 摘要介绍了一种短流程无缝不锈钢管材的制备工艺，即用空心铸坯直接热挤压制备荒管。
The results show that temperature gradient on the front edge of solidified shell in combined mold can be reduced and the proportion of equiaxial crystal of billet is more than 80 % 结果表明：复式结晶器能够降低钢液凝固前沿的温度梯度，从而使铸坯的等轴晶率超过80 % 。
The present paper reviews the current status and technical development ofr continuous caster productivity , improvement of product cleanliness and surface and internal quality of casting strand 综述了提高连铸机生产率、铸坯洁净度及铸坯表面和内部质量等方面所采用的技术措施。
In this paper , the internal transverse cracks of continuous casting slabs of a niobium - bearing peritectic grade of steel are investigated using electron probe microanalyser and optical microscope 摘要连铸坯厚度中心存在的内裂纹在后续的轧制过程中轧不合而对产品的质量带来重大的影响。
As the melt speed of sic in steel water is very slow and sic has the function of restrain the melting of free carbon in steel water , so the contain of carbon in steel is decreased 由于碳化硅中的碳熔解到钢水中去的速度极小，而且有抑制游离碳熔解到钢水中去的作用，因此减少了钢铸坯碳增量。
The object of my research work is to build a complete mathematical model for the secondary cooling process during cc process , and identify the unknown controlling parameters in it 本项研究工作的目标是建立完整的连铸二冷过程的传热数学模型以及利用铸坯的表面温度来辨识出二冷段一些喷淋工艺参数。
