  1. 1. Use of Thermal Analysis to reduce the Microporosity in ductile iron. : Analysis of micro porosity casting defect

    University essay from Jönköping University/JTH, Material och tillverkning

    Author : Adriana Mura; [2022]
    Keywords : Nucleation; Ductile Cast iron; Inoculation; Preconditioning; Over-inoculation; Charge materials; Hypoeutectic; Eutectic; Hypereutectic; Shrinkage;

    Abstract : It became always more important in Cast Iron Foundry to have a process control system that helps to reduce the variability and follow the correct specifications, to simplify the detection of eventual inoculation problems or incorrect working ranges.In the thesis, it is presented a case study of a specific defect of microporosity that appeared in the internal areas of some castings.

  3. 2. Inoculant measurement with thermal analysis

    University essay from KTH/Materialvetenskap

    Author : Christopher Armstrong; [2020]
    Keywords : Thermal Analysis; Inoculation; Nucleation; Compacted Graphite Iron; CGI; Cast Iron; Material Properties;

    Abstract : Over time the level of inoculant will decrease due to fading and this needs to be compensated bymore additions of inoculant. When casting CGI400 at Scania a one-step method is used, and the inoculant additions are based on the last ladle from the previous oven. READ MORE

  4. 3. The effect of a feruloyl esterase producing inoculant along with mechanical treatment prior to ensiling on fibre digestibility of grass silage

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Kiros Kelkay Haile; [2019]
    Keywords : ryegrass; in vitro incubation; feruloyl esterase; ensiling; meadow fescue; fibre digestibility;

    Abstract : Plant fibre is the main portion of dairy cattle diets. It is also important in maintaining health and proper function of the rumen. However, digestibility of fibre is relatively low, and, in most cases, it is not more than 60%. In cell walls of grasses and cereals, lignin and hemicellulose are connected, forming a matrix.

  5. 4. Investigation of the possibility for using ZrO2 and ZrSiO4 for Zr additions to liquid ferrosilicon

    University essay from KTH/Materialvetenskap

    Author : Amanda Vickerfält; [2017]
    Keywords : inoculant; ferrosilicon; zirconium; zirconia; zircon sand;

    Abstract : Ferrosilicon containing 50-75% Si and 1.0-5.0% Zr is used as inoculant in the cast iron industry. Zr can be added to liquid ferrosilicon by use of Zr metal or zirconium ferroalloy (FeSiZr). READ MORE

  6. 5. Feed intake, in vivo digestibility and protein utilization of grass, red clover and maize silages in sheep

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Elisabeth Saarsoo; [2015]
    Keywords : grass; maize; red clover; silage intake; digestibility; protein utilization; sheep;

    Abstract : Sheep in Sweden are usually fed grass/clover forage supplemented with concentrate during the winter season. Red clover forage fed to ruminants has shown to increase dry matter (DM) intake and give a lower in vivo DM digestibility compared to grass forage. READ MORE
