Laser-clad alloyed high manganese steel frog and manufacturing method thereof
The invention provides a laser-cladding alloyed high manganese steel frog and a manufacturing method thereof. The laser-cladding alloyed high manganese steel frog comprises a frog body made of high manganese steel. The frog main body comprises the following chemical components in percentage by mass: 1.0 to 1.3 percent of C, 12.0 to 14.0 percent of Mn, 0.3 to 0.8 percent of Si, 0 to 0.045 percent of P, 0 to 0.03 percent of S and the balance of Fe and trace impurities; an alloyed high-manganese steel cladding layer is arranged on the traveling surface of the frog main body with the width of 50mm from the throat to the point rail; the alloying high manganese steel cladding layer comprises the following chemical components in percentage by mass: 0.1 to 0.75 percent of Mo, 0.1 to 0.5 percent of Cr, 0.9 to 1.75 percent of Ni, 1.0 to 1.3 percent of C, 12.0 to 14.0 percent of Mn, 0.3 to 0.8 percent of Si, 0 to 0.045 percent of P, 0 to 0.03 percent of S and the balance of Fe and trace impurities. The technical problem of how to reduce and control the cost while how to improve the toughness, the wear resistance and the service life of the high-manganese steel frog is solved. The manufactured high-manganese steel frog is better in toughness and abrasion resistance, longer in service life, good in economic benefit and more suitable for popularization.
