Hiroki high temperature laboratory furnace laboratory furnace laboratory furnace intelligent

Shanghai Hiroki laboratory furnace is in line with the national standard energy cycle operations furnace, mainly for steel products, metal parts normalizing, hardening, annealing and other heat treatment purposes, such as diamond cutting blade or high temperature sintering purposes. Here's the installation method: 1. Shanghai Hiroki laboratory furnace without special installation, just flat on the floor or stand indoors. The controller should be on the table, the inclination of the work surface should not exceed 5 degrees. The controller Furnace minimum distance of not less than 0.5 meters away. The controller should not be placed above the furnace, so as not to affect the controller is working properly. 2. Control connected devices and electric power lines, switch and fuse load capacity should be slightly larger than the experimental furnace power rating of 3. When wiring, first turn the screw loose controller left and right sides of the housing, then turn on the cover, according to FIG. The power cord is shown. The controller and electric wires and thermocouple cable (preferably compensation wire). insert the thermocouple in the furnace thermocouple holder from the hole, the gap between the hole and asbestos rope thermoelectric jam, then fixed (Note: the power phase - and neutral is not reversed, in order to operate safe, reliable ground controllers and electric stove are required). 4. Check the wiring is correct you can power, first on the power switch, and then control toggle switch on the control panel to pull the open position, adjust the setting button, the temperature is set to the degree you need, if the switch is set to pull the measuring position, the red light is off (NO), also contact with the pick-up sound, electric powered, ammeter indicates heating current, temperature with the furnace temperature and slowly rising, indicating working properly. When the temperature rises to set the desired temperature, the red light is off (NO), Green light (YES), electric automatic power-off, stop heating up. Later, when the furnace temperature dropped slightly, the green light is off, the red light, electric and automatic power. Again and again, the purpose of automatic control of furnace temperature. 5. To Check that burnout protection devices to work, the method is: Loosen the thermocouple end, this time temperature quickly rose to the highest point of instruction also automatically cut off the heating power, the burnout means good, then good again after thermocouple can Normal working 6. oven, when the furnace again after the first time or for long periods, the oven must be carried out the process as follows: when the temperature rose to 200 ℃ 4 hours (open the door to let the steam distribution) When 200 ℃ to 600 ℃ 4 hours (close the door) when 600 ℃ to 800 ℃ 2 hours (close the door) 7. After use, first toggle switch on the control panel to pull off position, then cut off the mains switch.
