METHOD FOR PRODUCTION OF LOW-ALLOYED STRUCTURAL STEEL WITH BORON CONTENT 0,0015-0,0040 MACHINES,@

摘要

Usage: The invention relates to ferrous metallurgy and to a method of preparing boron-containing steel of pig iron. SUMMARY proposals lies in the fact that in the melting of iron steel is used, which components are taken in the following ratio,% by weight carbon 4.0-5.0.; 0,35-1,00 silicon, manganese, 0.1-1.5; Forest 0,015-0,040; remainder iron, with the ratio of silicon to boron concentration then taken within 23-25 ​​C. with known methods of smelting borsoder--containing steels by doping boron alloy 1, boron or other boron-containing waste materials 2. vj .vi iO CJ VI 4
