5 safe operation, fettling and when non-pound crucible, iron oxide mix, ramming crucible must be dense. 6, casting furnace pit site and should be no obstructions, no water, electric stove, to prevent the steel floor explosion. 7, the molten steel is not allowed to contain too full, hand pouring ladle, the two should be consistent with, walking should be smooth, not allowed Jizou stop, after pouring into the designated locations to more than steel, non-Dumping. 8, frequency generator room should be kept clean, non-inflammable and explosive materials and other debris into the room, no smoking. Before the experiment Step 2.1 powered, high-temperature furnace, check whether there is compliance with the wiring, the controller whether the upper terminal screws loosening phenomenon. 2.2 Weighed sample put and furnace, and close the door, laboratory furnace, open electric switch; 2.3 pull the switch on the controller to "set" position, the new all-fiber furnace, set test temperature; 2.4 set After the scheduled completion switch pull back to "Measuring" position, furnace temperature was raised to work, this time the meter displays by the green indicator light; 2.5 hours to turn off the electric switch, a sample was taken after cooling. The new all-fiber furnace, furnace, laboratory furnace by Longkou Longkou Furnace experiment. Longkou Experimental Furnace (www.lk-dianlu.com) strong, credible, in Yantai, Shandong electric equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Longkou laboratory furnace into the brilliant and you work for a better future!
