CONSUMABLE ELECTRODE TYPE VACUUM ARC REMELTING APPARATUS FOR MELTING AND CASTING TITANIUM

摘要

PURPOSE: A consumable electrode type vacuum arc remelting apparatus for melting and casting titanium is provided which is capable of manufacturing middle to large sized titanium cast components requiring accurate dimensions at low cost and preventing pollution during melting and casting processes. CONSTITUTION: The consumable electrode type vacuum arc remelting apparatus(1) for melting and casting titanium comprises a chamber(10) for forming an internal space; a vertical transfer means(20) fixed to the upper part of the chamber; a sample fixing means(30) which is moved by operation of the vertical transfer means and fixes sample; a vacuum means(40) connected to the chamber to maintain the inside of the chamber to the vacuum state; a double cooling structured crucible furnace(50) which is installed at the lower side of the sample fixing means, and in which skull(51) is installed; a current supply means for supplying current to sample (S) and crucible furnace; a crucible furnace rotation control means(60) in which the crucible furnace is connected to rotation shaft rotated by driving force of motor(61), and a reduction gear(63) is installed between the motor and rotation shaft(62); a mold(80) for casting a component having a melt troughing shape; a guide member(95) fixed to a bracket(16) of the chamber so that the melt is easily injected into the mold when pouring melt of the crucible furnace into the mold; a centrifugal disk(85) for rotating the mold; a power generating means(90) for providing power source to rotate the centrifugal disk; a cooling means for preventing heat generated by high temperature arc heat from transferring to the crucible furnace; and a control means(100) for controlling the respective units.
