More Information
Summary:The invention discloses a mine spray lance which comprises a metal body made from a thermally treated alloy material, wherein the alloy material comprises the following components: 1-2% of Si, 0.5% of N, 0.9% of B, 1.1% of Mg, 0.7% of Au, 0.6% of Tc and Cu and inevitable impurities in balancing amount. The alloy material is thermally treated through the following steps: 1) heating to 615 DEG C at the speed of 10 DEG C/min, and performing heat preservation for 3 h; 2) cooling to room temperature at the speed of 10 DEG C/min; 3) heating to 715 DEG C at the speed of 20 DEG C/min, and performing heating preservation for 2 h; and 4) cooling to room temperature at the speed of 20 DEG C/min. the metal body of the mine spray lance has good properties and a long service life.
