Note 1. When using the furnace temperature shall not exceed the maximum furnace temperature, and do not work at the rated temperature over time. 2. Working conditions: temperature 0 ~ 50 ℃, relative humidity <80%, non-conductive dust, no flammable materials and corrosive gases. 3. When using the oven door open to light the light off, to prevent damage to the parts. 4. When the sample in the furnace to take place, you should turn off the power, and gently industrial furnace, in order to ensure safety and to avoid damage to the furnace. 5. To extend product life and ensure safety equipment at the end of the furnace should be promptly removed from the sample, quit heating and power off. 6, the device ambient atmospheric pressure: 86.0 ~ 106.0Kpa IF frequency electric furnace is a 50HZ AC power frequency into an intermediate frequency (300HZ above to 1000HZ) of the power supply unit, three-phase power frequency alternating current is rectified into DC industrial furnace plant, then becomes adjustable DC IF current industrial hobs, supplied by the capacitor and the induction coil in the flowing medium frequency alternating current, resulting in high-density magnetic field lines in the induction coil, the induction coil and cut metal in full bloom material, have a great vortex in the metallic material. Due to the principle of electromagnetic induction heating induction industrial electric furnace, the heat generated in the workpiece itself, ordinary workers after ten minutes with electric furnace work can be carried out continuously forging tasks, without burning stove in advance of professional workers and burning furnace sealed furnace work. Industrial hobs _ Longkou experimental furnace (certified) _ Industrial Furnace Furnace by Longkou experiment. Longkou experiment Furnace (www.lk-dianlu.com) is a leader in Yantai, Shandong Province, electric equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Longkou laboratory furnace leadership with the staff warmly welcome all inquiries negotiations to create experimental furnace Longkou a better future.
