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, 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 the high-temperature furnace, 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 interior, electric stove, no smoking. Box-type resistance furnace parameters 1, power supply voltage: 220V2, heating power: 4KW3, heating element: electric wire / silicon carbide / silicon molybdenum rods 4, control: SCR control, PID parameter self-tuning function, manual / automatic switch non-interference function, over-temperature alarm function. 5, tube furnace, display accuracy: ± 1 ℃ 6, red temperature values: 1--3 ℃ 7, the display window: temperature measurement, set the temperature dual display, heated power beam display. _ _ Longkou electric laboratory furnace temperature furnace experiment by Longkou Furnace. _ _ Longkou electric laboratory furnace temperature furnace experiments Longkou Furnace (www.lk-dianlu.com) this year introduced a new upgrade, the above picture is for reference only, please call Tel picture on this page or to obtain the latest information Contact: Sui Jingli.
