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 pit carburizing furnace manufacturer, and close the door, open the electric switch; 2.3 pull the switch on the controller to "set" position, set the test temperature; 2.4 setup is complete After the switch is pulled back to the "Measure" position, furnace heating up work, this time by a green indicator instrument display; after 2.5 hours after the switch to turn off the furnace, remove the sample to be cooled. Car-resistance furnace structure: lining all-fiber structure, relatively brick hearth saving about 60 percent, using high-quality raw materials for long-fiber blanket thorn RQ3 series Pit carburizing Industrial resistance furnace, the furnace according to the size of a large plate made of the use of special equipment specification type carburizing furnace, and in the process leave some amount of compression, so the module after the masonry is completed, each ceramic fiber block in a different direction expansion, so that no gap between the modules mutually extruded whole, achieve good regenerative effect type tempering resistance furnace, and facilitate the rapid construction of the product, can be directly fixed to a stainless steel furnace shell plate anchor nailed round. Compared to the advantages of low thermal conductivity, low heat capacity, excellent corrosion resistance, excellent thermal stability and thermal shock resistance, thermal insulation, and the anchoring member disposed in the furnace cold, improves the high temperature strength of the fibers and other products. Pit carburizing furnace manufacturer, Pit carburizing furnace, laboratory furnace manufacturers to provide test by Longkou Furnace. 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!
