Step 2.1 is energized before the experiment, first check whether there is compliance with the wiring, whether the controller has the finest terminal screws loosening phenomenon. 2.2 weighed sample placed with the furnace, and close the door, turn on electric switch; 2.3 pull the switch on the controller to "set" position box furnace, set test temperature; 2.4 setup is complete switch to pull back to "measure" position, begin heating furnace work, then the instrument display by green lights; 2.5 hours after the switch to turn off the electric furnace 1300, after cooling the sample was removed. To shorten the cooling process time, trolley resistance furnace roof may be provided to accelerate the cooling exhaust. The heating apparatus is closed, cooled to a certain temperature to open, close the open side of the operation by an operator or automatically controlled by a manual mechanism to complete in an oven. Car-resistance furnace is the national standard of energy-efficient furnace operation cycle, mainly for high chromium, high manganese steel castings, ductile iron, roller, ball, hammer crusher, wear-resistant liner hardening, annealing, aging well kinds of mechanical parts used heat treatment furnace 1300, furnace, laboratory furnace provided by Longkou Longkou Furnace experiment. Longkou experiment 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 and you hand into the brilliant, for a better future!
