- the method according to the invention is preferably practiced with: a ferrous alloy comprising steel or cast iron; - aggregates of millimeter ceramic granules where aggregates of infiltrable ceramic precursors are selected from the following compositions: o Alumina-zirconia in proportions 90/10 to 10/90, the zirconia optionally being stabilized with yttrium oxide ; o Powdered carbon and titanium optionally comprising iron powder as a moderator of the reaction initiated by the casting of the ferrous alloy; o Metal-ceramic composites (CERMET).
- a ferrous alloy comprising steel or cast iron
- - aggregates of millimeter ceramic granules where aggregates of infiltrable ceramic precursors are selected from the following compositions: o Alumina-zirconia in proportions 90/10 to 10/90, the zirconia optionally being stabilized with yttrium oxide ; o Powdered carbon and titanium optionally comprising iron powder as a moderator of the reaction
- the inserts are defined as being infiltrable three-dimensional structures formed of more or less porous aggregates or even of agglomerates of millimeter particles with interstices.
- Figure 1 shows the element of a ceramic insert with blind holes according to the invention.
- the insert is presented here schematically in its simplest form. Such an insert is positioned on the blind side on the face most exposed to wear. Such an insert has many interstices, or pores (not shown) which are intended to be infiltrated by the ferrous alloy during casting.
- Figure 2 shows a ceramic insert based on the same principle as that described in Figure 1 but with larger blind holes to illustrate the different possibilities of making blind holes in such a ceramic insert.
- Figure 3 shows a ceramic insert with blind holes based on the same principle as that described in Figure 1 but this time the insert is in two different ceramic layers D and E.
- Figure 4 shows a ceramic insert with blind holes based on the same principle as that described in Figure 3 but this time with deeper blind holes penetrating into the second layer E.
- Figure 5 shows a ceramic insert with blind holes based on the same principle as that described in figure 3 but this time made with enlarged holes.
- Figure 6 shows a ceramic insert with blind holes based on the same principle as that described in Figure 1 but this time with blind holes associated in a proportion of about half and half to through holes of section bigger.
- Figure 7 shows a ceramic insert with blind holes based on the same principle as that described in Figure 1 but this time with blind holes associated in a minority proportion with through holes of larger section.
- the blind holes of smaller diameter than the through holes, are in the majority.
- Figure 8 shows a ceramic insert with two different stress areas A and B.
- the area A most exposed to wear mainly comprises blind holes and the area B less exposed to wear mainly comprises through holes.
- the through holes in zone B have a larger section than the blind holes.
- Figure 9 shows the same configuration as Figure 8 but this time with a different ceramic side A and side B.
- Figure 10 shows the same configuration as Figure 8 but this time not only with a different ceramic side A and side B, but also with two different ceramic layers D and E in zone A, with a more resistant ceramic wear on the blind side of zone A.
- Figure 11 shows a ceramic insert according to the invention with blind holes positioned obliquely.
- Figure 12 shows a ceramic insert according to the invention with blind holes of frustoconical shape.
- FIG. 13 represents an illustrative example of a wearing part according to the invention in the form of a grinding roller for a vertical rotary grinder where the zone A most exposed to wear comprises the ceramic insert with blind holes. Zone A is adjacent to Zone B with less wear and tear with through holes.
- Figure 14 schematically shows the use of a grinding roller on a table of a vertical rotary grinder.
- Figure 15 schematically shows a grinding cone with a ceramic insert with blind holes.
- Wear parts produced in a foundry are widely used in the mining industries for crushing rocks and ores or in the field of dredging. Without being limiting, we can for example cite, for the crushing of rocks, the composite impactors for impact crushers, the mobile cones of compression crushers or the tables of rollers of vertical compression crushers.
- Ceramic reinforcements are generally introduced in the form of a prefabricated ceramic insert or even in the form of an insert in which the interstices have already been filled with liquid cast iron and cooled before being reintroduced into a mold to cast the part wear that one wishes to obtain.
- composition possibilities for making an insert according to the invention there are many composition possibilities for making an insert according to the invention.
- Maintaining the insert in the mold during casting also requires a certain know-how acquired by manufacturers over the years.
- the inventors of the present invention have now produced a ceramic insert structure that perfectly meets this compromise.
- This has a perforated structure with blind holes, the blind side being placed on the most stressed side of the wearing part so as to offer a high resistance to wear at the start of use and once the blind side. (bottom of holes) worn, resistance to impact and wear by presenting through holes.
- the holes made in the structure of the insert have a diameter generally between 1 and 10 cm, preferably between 1 and 8 cm and particularly preferably between 1 and 4 cm.
- the depth of the blind holes depends on the total thickness of the insert and the specific use, it generally represents between 20 and 85% of the total thickness, preferably between 30 and 80% and particularly preferred between 40 and 70%.
- the insert can be made in several superimposed layers (D and
- the blind side can therefore be formed by a ceramic composition different from that comprising the holes which is superimposed or adjacent to it (see figures).
- holes are preferred for the holes, it is obvious that the invention is not limited to this shape.
- the holes can therefore have any shape of section, for example hexagonal squares or any shape.
- blind holes sit alongside through holes, the proportion of blind holes must however be significant, that is to say greater than 20%, preferably greater than 40% and particularly preferably greater than 60%.
- the terminal holes in the most stressed area of the wear part have a section and / or an opening area smaller than that of the holes in the least stressed area.
- the general concept of the invention lies in the fact that the first wear is on a side reinforced by an insert mainly devoid of holes, here in this case the blind side of the insert, which once worn offers always a strong resistance to wear with through holes of a smaller cross section compared to the through hole sections located on the least stressed side of the wearing part.
- the invention is not limited by a precise composition of ceramics, ceramics based on alumina-zirconia or even titanium carbide, placed as such in the mold (cermet grains) or formed in situ by self-propagating thermal reaction are however preferred. Proportions of alumina-zirconia comprising 10 to 90% alumina and 90 to 10% zirconia by volume are preferred, the zirconia optionally being stabilized with yttrium oxide.
- the present invention has been exemplified by a roller of a vertical rotary crusher and moving parts of a cone crusher which have been produced with, on the one hand, an insert comprising through holes according to the state of the art and d 'on the other hand with inserts essentially comprising blind holes according to the invention.
- Machine type Secondary cone crusher Type of wearing part: Moving part
- Type of ground material Rhyolite 50-150 mm
- Type of crushed material Silico-Limestone Number of operating hours with and without through inserts on the most stressed part:
