弹丸发射器由首钢机械厂负责设计试制,与特钢公司等单位采用发射器进行射铝的工艺试验,取得满意的结果,并于今年获得中国专利局对于此项发明的专利权。用发射器向包内发射铝弹丸可使铝的收得率比正常冶炼提高30％以上。又因控制准确,所以对改善质量,起到了促进作用。 The projectile launcher was designed and manufactured by Shougang Machinery Factory and tested with the special steel company and other units using the launcher for aluminum casting. The projectile launcher achieved satisfactory results and won the patent of the Chinese Patent Office for this invention this year. Launching an aluminum projectile into the bag with a launcher can increase the yield of aluminum by more than 30% over normal smelting. And because of accurate control, so to improve the quality, has played a catalytic role.
