E ⁇ iron m ⁇ zhe ⁇ by ⁇ is ⁇ lz ⁇ van for izg ⁇ vleniya de ⁇ aley, ⁇ ab ⁇ ayuschi ⁇ in usl ⁇ viya ⁇ ab ⁇ azivn ⁇ g ⁇ izn ⁇ sa.
This alloy has a relatively high wear rate under conditions of abrasive wear due to impact and contact pressures.
alloy steel is alloyed ( ⁇ , ⁇ , 587170), 15% (wt.%): Carbon 2.5 - 3.2 ⁇ m. 9.0 - 10.8 brown ' 1.2 - 2.4 manganese 11.0 - 15.0 20 cerium 0.001 - 0.2 vanadium 0.15 - 0.3 iron other
This steel can be used in the manufacture of massive, sophisticated parts for metal and mining 25.
the main task of the present invention is to create a cast steel by means of the correspondingly available and commercially available products.
cast steel is used at the following composition of components (wt.): Carbon 2.4 - 3.0 extreme 1.4 - 1.6 manganese 12.9 - 15.0
composition of the steel makes it possible to increase the increased wear and tear of the device due to the abrasive wear and tear in the case of negligible impact loads.
the filling of the wide range of materials is carried out in the following order: Exit and return of the actual production - the main line; after melting ⁇ réelle ⁇ ; ⁇ réelle ⁇ - manganese; ssen ⁇ vanadium; Oxidizing agents - brown, aluminum; 30 modifiers - titanium, boron, cerium.
Received cast steel has compositions (wt.%): - 5 - carbon 1, 6 - 3.0 ⁇ pon minimum 1.2 - 1.6 manganese 11.0 - 15.0 ⁇ ⁇ 9.0 - 10.8
the carbon content in the steel is 1.6–3.0 wt.%, which ensures the formation of an optimal quantity of small amounts of carbohydrates of type C ⁇ and C.
the content of brown is 1.2 - 1.6 wt.% Is necessary for the reduction of steel, to ensure good fluidity and more complete absorption of cerium and boron.
Composition of seeds more than 1.6 wt.% Results in the formation of harmful silicides resulting in intermittent destruction.
a content of 25 mg and less than 1.2 wt.% Does not produce a noticeable effect.
the manganese content of 11.0-15.0 wt.% Ensures the necessary level of properties and the emission of the old base has ceased.
the content of the chrome in the steel was 9.0-10.8 wt.%, which ensures 30% of the required level of property due to the easing of the austenit and the formation of dispersed carbides in the matrix,
the cerium and vanadium content in the steel was 0.001-0.2 wt.% And 0.15-0.3 wt. Corresponds to the grinding of the original grain in steel, increasing its impact viscosity 35%.
the main component of steel is iron, hardware - 6 - the indicated alloying elements in it are contained in wt.% Of admixture: sulfur up to 0.03, odds up to 0.1, and admixtures in total (Si, sh, Ca) up to 0.5.
Titanium introduced into steel in the following areas: facilitates the grinding of eutectic barbids and cleans grain boundaries from non-metallic inclusions. The result is the selection of barbecue, barbecue and
the steel provides a * matrix with the separation of the second phase (carbides, borides, nitrous ores), which are connected to the matrix with voltage pulses.
Reduced aluminum s ⁇ de ⁇ zhaniya less than 0.05 wt.% Does not ⁇ azyvae ⁇ Su- sches ⁇ venn ⁇ g ⁇ influence ⁇ m ⁇ zhenie ⁇ s ⁇ a ze ⁇ na aus ⁇ eni ⁇ a, ⁇ a ⁇ ⁇ a ⁇ ⁇ liches ⁇ v ⁇ dis ⁇ e ⁇ sny ⁇ chas ⁇ its ⁇ sh and not great.
An increase in the aluminum content of the above-mentioned range (0, 15 wt.%) Is inappropriate, due to the growth of arterial particles in the form of arboreal species. ⁇ As a result, the steel is hardened, impact toughness and wear are reduced.
