Multiple Composite Rare Earth Tungsten Electrodes Swaging String Playing Equipment Technology Invented Concrete Steps

Multiple composite rare earth tungsten electrodes swaging string playing equipment and technology invention uses string playing devices relative position of each device is as follows : The first furnace tube length of 1m molybdenum wire furnace, the first furnace and the first rotary swaging machine 2 the distance between 15cm ( 15cm i.e. the gap between the two ) , the first guide roller and the first rotary forging machine and the distance between the second furnace are 10cm, the second furnace to furnace tube length 0.7m molybdenum wire tube furnace , and the second rotary forging machine 5 and the distance between the second furnace 15cm, and the second guide roller and the distance between 10cm.

B203 selected will pass the billet forging Φ6.5 string into boron oxide playing machine for processing , the blank of the composition: percentage by weight , of rare earth oxide content of 0.44% lanthanum oxide , yttrium oxide, 1.32% , 0.44% oxide cerium , and the balance tungsten, first the first furnace , a second heating furnace 4 heated to 1470 ℃, the billet feed speed is controlled 2m/min, the first step of setting a first rotary hammer 2 and the the second rotary hammer machine 5 with mold system as the Φ6.0, Φ5.6, the first guide roller 3 speed 2.3m/min, the second guide roller 6 speed is set to 2.7m/min, after the first procedure after processing , the billet into the distribution system as the model Φ5.2, Φ4.8 string play equipment for the second processing procedures , the first and second heating furnace 4 furnace a temperature set at : 1430 ℃, the first a guide roller 3 speed 2.3m/min, the second guide roller 6 speed is set to : 2.7m/min; billet into the match after molding system as : Φ4.4, Φ4.1 the third step processing the first and second heating furnace 4 furnace temperature was set at 1430 ℃, the first guide roller 3 speed of 2.4m/min, the second guide roller 6 speed to : 2.7m/min; three after the process , began to enter the B201 stage in the B201 stage tungsten processed through two processes , the first process with mold system as : Φ3.9, Φ3.6, first one and the second furnace temperature furnace 4 as : 1430 ℃ first guide roller speed of 2.2m/min, the second guide roller temperature to 2.6m/min. Second step with mold system as the Φ3.3, Φ3.0, first and second furnace temperature furnace 1 as : 1370 ℃. The first guide roller 3 speed 2.4m/min, the second guide roller 6 speed is set to : 2.9m/min, a variety of specifications available Φ6-Φ3 rare earth tungsten electrode material .
