Abstract
A molten metal transfer pipe 52 for transferring an injection sleeve 51 has a bent pipe portion 3 thereof reduced in diameter to provide a throttle part 4 attaining a pressure loss effect. A melting and holding furnace 101 with a tilting mechanism has a melting and holding furnace section 101 and an electrical lifter 113 for holding the melting and holding furnace section 101 horizontally and for tilting the melting and holding furnace 101 together with a molten metal supplying apparatus 102 upwardly about the melting chamber 104 serving as a tilting fulcrum C to hold the same in the tilted position. An ingot charging apparatus 201 includes a hood 208 mounted to a conveyor 205 for conveying each preheated magnesium ingot MA, which, at a discharge time of the preheated magnesium ingot MA and at a charge time of the same, communicates with an ingot discharge port 202a of a preheating apparatus 202 and an ingot charge port 203a of a melting and holding furnace 203a to define closed spaces 207 and 206 for allowing a discharge operation of the preheated magnesium ingot MA and a charge operation thereof, and which covers the preheated magnesium ingot MA held by an ingot chuck 204 during …
