摘要： A feeder system for metal casting comprising a feeder sleeve mounted on a tubular body. The feeder sleeve has a first end and a second end and a longitudinal axis extending generally between said first and second ends. The feeder sleeve comprises a continuous sidewall that extends generally around the longitudinal axis that defines a cavity for receiving liquid metal during casting and the sidewall has a base at the first end of the feeder sleeve. The tubular body defines an open bore therethrough for connecting the cavity to the casting in use. The feeder sleeve comprises at least one cut-out that extends into the sidewall from the base to a first depth and the tubular body projects into the cut-out to a second depth, the tubular body having at least one abrading region in contact with a surface of the feeder sleeve within the cut-out. The second depth is equal to or less than the first depth so that upon application of a force in use the abrading region abrades the surface of the feeder sleeve with which it is in contact such that the tubular body is pushed towards the second end. The invention also resides in a feeder sleeve for use in the system and a process for preparing a casting mould employing the system.

摘要： The present invention relates to a feeder system for metal casting. The feeder system comprises a feeder sleeve mounted on a tubular body. The feeder sleeve has a longitudinal axis and comprises a continuous sidewall that defines a cavity for receiving liquid metal during casting. The sidewall extends generally around the longitudinal axis and has a base adjacent the tubular body. The tubular body defines an open bore therethrough for connecting the cavity to the casting. A groove extends into the sidewall from the base to a first depth and the tubular body projects into the groove to a second depth and is held in position by retaining means. The second depth being less than the first depth so that upon application of a force in use the retaining means are overcome and the tubular body is pushed further into the groove.

摘要： An elongate collapsible feeder element (20; 40) for use in metal casting and a feeder system comprising the feeder element and a feeder sleeve secured thereto.
The feeder element (20; 40) has a length, a width and a height and comprises an A end and an opposite B end measured along the height, and a C end and an opposite D end measured along the length, said A end for mounting on a mould pattern or swing plate and said opposite B end for receiving a feeder sleeve; and a bore between the A and B ends defined by a sidewall comprising a stepped collapsible portion.
The feeder element is compressible in use whereby to reduce the distance between the A and B ends. The sidewall has a first sidewall region (24;52) defining the B end of the feeder element which serves as a mounting surface for a feeder sleeve in use, and a second sidewall region (38; 50) contiguous with the first sidewall region (24;52). The stepped collapsible portion comprises a series of third sidewall regions (32a,b,c,d; 44a,b) in the form of concentric rings of decreasing diameter interconnected and integrally formed with a series of fourth sidewall regions (34a,b,c,d; 46a,b) in the form of concentric annuli of decreasing diameter.
The bore has an axis that is offset from the centre of the feeder element along the length towards the C end and said second sidewall region (38;50) is non-planar, contiguous with a third sidewall region and located between the bore axis and the D end.摘要翻译： 一种用于金属铸造的伸长的伸缩式供料器元件（20; 40）和一个包括供料器元件和固定在其上的供料器套筒的供料器系统。 馈送元件（20; 40）具有长度，宽度和高度，并且包括沿高度测量的A端和相对的B端以及沿该长度测量的C端和相反的D端，所述A端用于 安装在模具图案或摆动板上，并且所述相对的B端用于接收进料器套筒; 并且A和B端之间的孔由包括阶梯式可折叠部分的侧壁限定。 馈送元件在使用中可压缩，从而减小A端和B端之间的距离。 所述侧壁具有第一侧壁区域（24; 52）和第二侧壁区域（38; 50），所述第一侧壁区域（24; 52）限定所述供给器元件的B端部，所述供给器元件的B端部用作供料套筒在使用中的安装表面，所述第二侧壁区域邻接所述第一侧壁区域 24; 52）。 阶梯式可折叠部分包括一系列第三侧壁区域（32a，b，c，d; 44a，b），所述第三侧壁区域以减小直径的同心环的形式互连并与一系列第四侧壁区域（34a，b，c ，d; 46a，b）以直径逐渐减小的同心环的形式。 所述孔具有轴线，所述轴线沿着朝向C端的长度偏离供给器元件的中心，并且所述第二侧壁区域（38; 50）是非平面的，与第三侧壁区域邻接并且位于孔轴线和 D结束。

摘要： The present invention relates to a process for the production of ductile iron comprising the sequential steps of:- (i) treating liquid iron with an initialiser comprising an effective amount of a group IIa metal other than Mg, (ii) at a predetermined time after step (i), treating the liquid iron with a magnesium containing nodulariser, (iii) treating the liquid iron with a eutectic graphite nucleation-inducing inoculant, and (iv) casting the iron. The invention allows for the variability of oxygen content in the base iron to be processed such that the mechanical properties of components cast from the processed iron are independent of the original oxygen content of the base iron.

摘要： The invention relates to an impact pad (20), for use in a T-shaped tundish (10), the pad (20) comprising a base (21) having an impact surface and an outer side wall (22) extending upwardly therefrom and defining an interior space having an upper opening (24) for receiving a stream of molten metal. This pad is characterized in that the interior space is divided into two regions (25a,25b) by a separating wall (26) provided with at least one passageway (27) for the molten metal stream, the separating wall (26) extending upwardly beyond the outer side wall (22). This impact pads increases the homogeneity of the molten steel cast from the different outlets of the T-shaped tundish and provides equal or relatively similar residence times of the molten steel discharged through the different outlets of the tundish. This impact pad also permits a fast transition of the steel quality at ladle change while retaining the advantages of conventional impact pads (low level of slag emulsification).
