Definitions
- feeder includes both feeder shells, feeder inserts and feeder caps, and heating pads.
- hollow spheres are often used today, originating from the fly ash of coal-fired power plants.
- these hollow spheres suitable for use in feeders are not available without restriction in the necessary qualities.
- the use of synthetic hollow spheres is possible.
- these often do not have the required properties in order to achieve good insulating properties in the finished feeder. It was therefore the object of the present invention to provide a lightweight filler, which can be used as a replacement for the currently favored hollow spheres.
- core-shell particles for use as a filler for feeder masses for the production of feeders, comprising
- core-shell particles having a d10 value in the range of 0.30 mm to 0.40 mm and a d90 value in the range of 0.50 mm to 0.60 mm, it is particularly preferred if the core-shell particles have a mean particle size d50 of 0.4 mm to 0.5 mm, preferably a mean particle size d50 of 0.42 mm to 0.47 mm, more preferably a mean particle size d50 of 0.44 to 0.46 mm.
- cores (a) each having one or more cavities and a wall enclosing these cavities the cores (a) having a d50 value in the range of 0.15 to 0.45 mm,
- the core-shell particles prepared according to Embodiment 3 are homogeneously mixed with cold box binder (Hüttenes-Albertus: benzyl ether resin based on activator 6324 / gas resin 7241 with a ratio of activator 6324: gas resin 7241 of 1: 1). From the resulting mixture, feeder caps and other profile tablets (a) are stamped and (b) shot with core shooters (e.g., Röper, Laempe). Curing takes place in each case by gassing with dimethylpropylamine.
- Comparative Example 3 (not according to the invention)
- the core-shell particles prepared according to Comparative Example 1 are mixed with cold box binder (Hüttenes-Albertus: benzyl ether resin based on activator 6324 / gas resin 7241 with a ratio of activator 6324: gas resin 7241 from FIG : 1) homogeneously mixed. From the resulting mixture feeder caps and other profile moldings (a) are stamped and (b) shot with core shooting machines (eg Röper, Laempe). Curing takes place in each case by gassing with dimethylpropylamine. Comparative Example 4 (not according to the invention)
- a safer density feed could be proven for all embodiments.
- an improved cupping behavior was determined compared to the comparative examples.
- the determined voids depths are shown in the following table.
- a negative void depth value means that the void is at least partially in the casting, while a positive void depth value means that the void is formed in the respective residue vaporizer.
- the corresponding cube castings with residual feeders are shown in Figures 4 to 8.
