铸造技术的发展已经超出了传统牛顿流体在重力条件下充型与凝固的范畴,流变学在铸造工艺理论中的反映日趋强烈,急需探讨和构建基于非牛顿流体的铸造工艺理论,为铸造新技术的健康发展提供必要的理论支撑。本文对近年来国内外基于非牛顿流体的铸造工艺理论研究成果进行了综合归纳,形成了非牛顿流体压力成形工艺理论的基本框架,提出了非牛顿流体充型能力的评价方法和理论预测模型、非牛顿流体的补缩机理与致密化条件以及非牛顿流体表观粘度的理论计算模型。

研究发现,合金钢挤压铸造有其一系列特殊性,如合金钢挤压铸造总压下量计算中的线收缩率仅为传统铸造收缩率的1/2~1/3;估算脱模力时需要考虑静摩擦力,而不是动摩擦力,否则容易导致无法脱模;给出了定量确定挤压力的计算公式。生产实践证明,合金钢挤压铸造中寿命最短的模具零件是压头、芯杆和形成型腔的模芯和压室,它们的异常失效形式主要有端部墩粗、开裂、粘焊或冲焊。防止这些异常失效的最有效途径是合理使用涂料。最近,合金钢挤压铸造在煤矿液压设备和电气化铁路等领域获得了新应用。

通过对凝固层的受力分析,提出了滞留层初期尺寸的预测模型及定量计算方法,并据此分析了各工艺因素的影响趋势。结果表明,在通常范围内增加结晶器直径或减小其长度、提高凝固系数或提高结晶器内的纵向温度梯度、减小拉坯速度、降低制浆室高度、改善结晶器润滑,都可以提高初期裂口的形成位置,减小滞留尺寸,进而有利于提高半固态连铸过程的稳定性。验证实验表明,这一预测模型的误差在5%~10%范围内。

介绍了连续冷却和搅拌条件下树枝晶向粒状晶转变的填充司隙(FAS)和颈缩熔断(NMAR)两种机制,并通过理论推导得到了可以用来计算其转变时司的数学公式。两种机制下的转变时司计算结果与实验结果吻合较好。

【期刊论文】Basic rules for rheologic forging process of semisolid alloy

Semisolid mold forging is a major type of semisolid processing, which is different from neither traditional mold forging nor traditional permanent casting. However, processing defects are often seen in work pieces because of lacking available rules for the process design and control. Some basic rules for the process design and control, simply named the shortest flowing length, pressure filling and the minimum uplifting mold pressure, are advanced in the paper based on amount of researches and experiments. The equations to determine the major process parameters are given out such as the filling pressure, forming pressure and locking mold pressure for the process design and control. The rules and equations are experimentally proved available and applicable by several actual work pieces produced by the semisolid forging process.

【期刊论文】Effect of Process Factors on Microstructure of Semisolid Continuous Casting Billets
邢书明, Shuming Xing, Qijie Zha, Hanqi Hu

Semisolid continuous casting (SSCC) is a new technology to produce billets for semisolid metal forming (SSMF). The effect of process factors, such as pouring temperature, stirring rate, preheating temperature and thermal conductivity, of stirring chamber, on the microstructure of SSCC billets was studied by means of the factorial experimental method. The results show, that the microstructure of SSCC billets can be controlled by the above-mentioned four process factors. In order to obtain free and rounded granular grains in an SSCC billet, the pouring temperature, preheating temperature and stirring rate should be kept in a moderate nnlge, and the thermal conductivi D, of stirring chamber should be high. The regression equations with the process factors connecting the microstructure was also set up based on experimental data

The mold-filling ability of the semisolid alloy has very important effects on the quality and properties of the work pieces produeed by the semisolid forming process. The factorial experiments show that all of the heating factors, such as mold temperature, heating temperature and the keeping time of billets, have some effects on the mold-filling ability of semisolid alloy. According to the analysis of iniluencing extent on the filling ability, it is found that the most important one oftha factors is the mold temperature instead of the billets temperature, the next one is the heating temperature of the billet, and the keeping time rows on the third. 11 is also found that there is an interrelation between the billet heating temperature and the mold temperature. The effect of the interrelation on the mold-filling ability is even stronger than the keeping time. The higher the mold temperature, heating temperature or the keeping time is, the hatter the mold-filling ability of the semisolid alloy is. The parleter lvdcibe the mold-filling ahili, defined as the maximum filling height along the upright direction or the maximum filling length along the horizontal direction, can be theorefieaily determirtad according to the flowing theory of viscous fluid.

Semisolid rheologic forming process has become a new focus in the field of semisolid process because of its many obvious advantages such as shorter process route, smaller investment, lower cost and without reheating, compared with the thixptropic forming process. However, there are many key problems to be solved in its industrialization such as how to manufacture the semisolid slurry quickly, how to control and adjust the slurry quality efficiently, how to ration the slurry to pour into molds, how to design the mold and the forming process parameters etc. A product line of semisolid rheologic forging to produce steel castings used in rolling stocks has been constructed according to the research results. It is proved that a combination of several methods for manufacturing slurry, stirring and chemical grain refining, is a useful way to accelerate the slurry preparation and to control the slurry quality; that using a special pouring equipment with short and thick pouring nozzles and supplying an additional pressure are two available methods to pour successfully; that an automatic control system, especially the on line or real time concatenation control of the system is necessary in the rheologic forming process; that the mold material used in the rheologic forming process can be selected referring to the die-casting or the squeeze casting process; and that an actual and valuable way to increase the mold life is to form a special coating on the inner surface by the surface coating technology.

The major unsteady phenomena in semis,olid continuous casting process are the breakage and breakout. The essential reasons for them are the passageway bbcking or the solidified shall too thin lo endure the wilhdrawal force be cause d the remained shall formed at the beginning and its developing afterwards. Through theoretically analyzing the crack filling and the remained shall developing, stability conditions were presented. The essential one of them is that the stress acted on the semis,olid slurry must be larger lhan the yield stress of it. The condition without breakage is lo build a balance belween the increase of the remained shall resulted in s,olidifying and the decrease of it resulted in flowing of the semis,olid slurry. The condition without breakout is lo ensure the solidified thickness larger than the safe thickness. The corresponding mathematical formulas of these conditions were set up and the verification experiments show lhat these con ditions are reliable in applications.
