Aluminum-zirconium-titanium-carbon grain refiner and method for producing the same

A method comprising the steps of:

• a. melting commercially pure aluminum, heating to a temperature of 1000-1300 Celsius, and adding zirconium, titanium and graphite powder thereto to be dissolved therein, and
• b. keeping the temperature under agitation for 15-20 minutes, and performing casting molding to obtain an aluminum-zirconium-titanium-carbon (Al—Zr—Ti—C) intermediate alloy having dispersed ZrC and Al4C3 mass points and a chemical composition consisting of:
• 0.1%˜10% Zr, 0.1%˜10% Ti, 0.01%˜0.3% C, and Al in balance, based on weight percentage.
