Abstract

The invention discloses friction no-spark aluminium casting alloy for mine fan parts, relating to aluminium casting alloy materials. The friction no-spark casting aluminium alloy comprises the following components in percentage by weight: 1.0-2.5 percent of Zn, 2.5-6.0 percent of Cu, 0.1-0.3 percent of Cr, 0.1-0.15 percent of Ti, 0.3-0.8 percent of Mn, 2.5-4.5 percent of Re (rare earth elements), not more than 1.5 percent of Si, not more than 0.5 percent of Mg, not more than 0.5 percent of Fe, and the balance of Al. The invention solves the problems of difficult smelting operation, high cost, hard realization in traditional technology, and has the advantages of favorable safety of friction sparks, little material components, low cost, simple batching and convenient implementation.

Description

technical field [0001] The invention relates to a cast aluminum alloy material, in particular to a friction-free spark-free cast aluminum alloy material for parts such as a mine ventilator. Background technique [0002] Mine ventilators, portable electric drills, wind coal drills, electrical equipment casings, etc., have caused many accidents due to sparks generated by impact or friction. Therefore, foreign developed countries have long conducted research on the safety of light alloy materials used in mines, but no breakthrough has been made so far. At present, many countries have banned the use of equipment made of light alloys in coal mines or within 300m of mining faces with methane hazards. my country has also made strict regulations on the use of light alloy materials for mining: because the sparks generated by the impact or friction of light alloy materials (such as ZL401 GB / T1173-1995) are most likely to ignite gas and cause explosion accidents, it is forbidden to us...
