The General Kinematics VIBRA-DRUM® Dross Reclamation Mill quickly liberates precious metals from slag and dross, quickly recovering your valuable material. The VIBRA-DRUM® is able to be run in either a continuous or batch process through GK’s automated retention system. Optional lifting mechanism enables the drum to both quickly clean-out when run in batch form, but […]
An inoculant is a material added to the liquid iron just prior to casting that will provide suitable sites for nucleation of graphite during the subsequent cooling. Tradi tionally, inoculants have been based on graphite, ferrosilicon or calcium silicide.
Dia Casting And Its Types By Alpha Metal Industries - Aluminum Pressure die casting is defeated high volume run parts with more slender divider thicknesses.Die casting is a metal forcing so as to throw process that is described liquid metal under high pressure into a mold cavity.

inoculation, in medicine, introduction of a preparation into the tissues or fluids of the body for the purpose of preventing or curing certain diseases. The preparation is usually a weakened culture of the agent causing the disease, as in vaccination vaccination,means of
Late inoculation (i.e. as close to the mold cavity as possible) is the preferred method of insuring optimum inoculation of all types of graphitic cast iron. Casting microstructures and mechanical properties can be achieved with the least amount of inoculant material and …
Abstract: Casting simulation requires high quality information about the thermophysical properties of the alloy, but the nuer of alloys for which such information is available is limited. In this paper, a solution of Butler’s formulation for surface tension is presented for

A typical cast structure of a solid-solution alloy with an inner zone of equiaxed grains is shown in Fig. 1b. This inner zone can be extended throughout the casting, as shown in Fig. 1c, by adding an inoculant (nucleating agent) to the alloy. The inoculant induces
Two types of cups are currently widely used in casting prac-tice: sand cups and metal cups (see examples in Fig. 6). Sand cups are cheaper, but a metal cup allows for a more precise positioning of the thermocouple and more consistent fill-ing. Figure 7 shows

In the previous section (section 5) it was noted that the process of BNF takes place after a legume root has been infected by soil bacteria of the genus Rhizobium. It was also noted that these bacteria are capable of living naturally in the soil, without legumes present. When forage legumes are grown in these soils, the rhizobia already present infect the roots of the plants and form nodules
When comparing un-inoculated and inoculated irons, differences in microstructure are easily revealed, which again will strongly affect the final mechanical properties of the casting. Through inoculation, the graphite nucleation and eutectic undercooling of the iron can be controlled and this will be of crucial assistance in giving the iron its required service properties.
is used for a casting which solidifies slowly and vice versa. A gate should not have sharp edges as they may break during pouring and sand pieces thus may be carried with the molten metal in the mould cavity. Types Top gate Bottom gate Parting line side gate

Inoculation has a visible, beneficial effect in both the surface layer and the body of casting. Even with the highest solidifiion rate, at the surface layer of the 25mm round bar samples, the structure has the lowest graphite nodularity (15-20%), due to the sulphur content in the mould binder, in contrast with 40-50% nodularity in the casting body.
The global ferrosilicon market size was estimated at 7,610.0 kilo tons in 2015. The increasing demand for ferrosilicon (FeSi) as a deoxidizer in the steel industry and as an inoculant in the casting industry is expected to drive the market over the forecast period
The types of graphite formed enable the control of physical properties of gray and ductile irons that make these irons so important to industry. It is important that the inoculant is dry prior to use and that the correct amount by weight or volume be used.
