Description
Przedmiotem wynalazku jest sposób zabezpie¬ czenia gladzi rdzennika górniczego stojaka lub przesuwnika hydraulicznego przed uszkodzeniami mechanicznymi oraz dzialaniem korozji.The subject of the invention is a security method connecting lines of the core box of a mining rack or the hydraulic shifter against damage mechanical and corrosive effects.
Powierzchnie zewnetrzne rdzenników, dla za¬ pewnienia szczelnosci i odpowiedniej zywotnosci uszczelnien, musza byc bardzo odporne na uszko¬ dzenia mechaniczne, posiadac wysoki stopien glad¬ kosci i byc bardzo odporne na dzialanie korozji Narazone sa one na dzialanie zróznicowanych wa¬ runków geologicznych przy zmiennej korozyjnosci srodowiska kopalnianego, wód chemioznie agre¬ sywnych i na dzialanie uszkodzen mechanicznych powodowanych urobkiem.The outer surfaces of the core boxes for ensuring tightness and adequate durability seals must be very resistant to damage mechanical, have a high degree of smoothness bones and be very resistant to corrosion They are exposed to the action of various shafts geological plots with variable corrosivity mine environment, chemically aggressive waters strong and to mechanical damage caused by the spoil.
^Znane sa rózne sposoby zabezpieczenia gladzi rdzennika przed niszczacym dzialaniem korozji na przyklad przez nakladanie metoda gailwaniizapcji chromem technicznym lub brazem. Stosuje sie równiez nakladanie metoda . metalizacji powlok cynkowonglinowych. Powloki .te mimo dolbrych wla¬ snosci mechanicznych, naniesione bezposrednio na powierzchnie stalowe maja mala waiitosc jako za¬ bezpieczenia gladzi rdzennika przed uszkodzenia¬ mi imeicihanicznynii i korozija.^ There are different methods of securing the gloss core box against the destructive effects of corrosion on example by superimposition method of snapping cap technical chrome or bronze. Apply also overlapping method. metallization of coatings zinc carbon. These coatings are not yet poured in mechanical properties, marked directly on steel surfaces have a low value as a n protection of core box cores against damage me imeicihanicznynii and corrosion.
Powstale uszkodzenia gladzi powoduja stosun¬ kowo szybkie zuzywanie sie uszczelek, co pociaga za soba koniecznosc zwiekszenia czestotliwosci -re¬ mom/tów stojaków i przesuwników hydraulicznych, a tym samym podwyzszenie kosztów wydobycia i obnizanie wydajnosci. Uszkodzenia tepowojduja nie¬ kiedy obnizenie sprawnosci i niezawodnosci dziala¬ nia ukladów hyidraulaicznyioh, co ma istotne znacze¬ nie dla technologii procesu wybierania kopalin.The resulting damage to the coals causes sexual intercourse very fast wear of the seals, which causes a pull for himself the need to increase the frequency -re¬ torque of stands and hydraulic shifter, thus increasing the cost of extraction and performance degradation. The damage does not occur when the decrease in efficiency and reliability of operations of hyidraulic systems, which is of significant importance not for the mining process technology.
Wymienionych wad i niedogodnosci n(ie ma spo- sób zabezpieczenia gladzi rdzennika wedlug wyna¬ lazku. Istota tego sposobu polega na tym, ze na stalowy ulepszony cieplnie rdzennik naklada sie powloke niklowa o zawartosci do 20% fosforu o grubosci do 50 /Mm. a nastepnie wygrzewa sie ja io ' w temperaturze do 600°C w celu uzyskania pla¬ stycznosci powloki i uodpornienia jej na dziala¬ nie korozji przy podwyzszeniu jej twardosci po¬ wyzej 700 kG/mni2. Hartowanie indukcyjne ma na celu podwyzszenie twardosci warstwy lezacej ^ bezposrednio po;d powloka niklowa do twardosci powyzej i5i0 HjRC oraz lepszego zwiazania powlo¬ ki z podlozem. Tak wykonane zabezpieczenie gla¬ dzi rdzennika zapewnia odpowiednia odpornosc rdzennika na uszkodzenia mechaindiczne jalk i dzia- w lanie korozji.The abovementioned defects and inconveniences (there is no the means of securing the core core according to the invention lazku. The essence of this method is that on the heat-treated steel core box is overlapped nickel coating with phosphorus content up to 20% o thicknesses up to 50 / mm. and then it warms up o 'at a temperature of up to 600 ° C in order to obtain the plas contact of the coating and its resistance to the action no corrosion while increasing its hardness after more than 700 kG / mni2. Induction hardening has to increase the hardness of the underlying layer ^ directly after; d nickel coating for hardness above i5i0 HjRC and better bonding of the coating ki with the substrate. The glass protection thus made Thanks to the core core, it provides adequate resistance core box for mechanical damage to the shelves and in pouring corrosion.
