I. Outline the cycle operation mode of the resistance furnace, using iron-chromium-aluminum alloy wire as the heating element, and the high temperature in the furnace is 1000 °C. The electric furnace comes with an intelligent temperature control system that measures, displays, and controls the temperature inside the furnace and keeps the temperature inside the furnace constant. The resistance furnace adopts new refractory and heat-insulating fiber materials, has the characteristics of warming block, light weight, high efficiency and energy saving, and can be used for laboratory, industrial and mining enterprises, scientific research units for elemental analysis and quenching, annealing, tempering and other heat treatment of general small steel parts. For heating.
Second, the main technical parameters:
Rated power: 4KW furnace temperature stability: ≤ ± 1 ° C
Rated voltage: 220V furnace temperature uniformity: ≤ ± 6 ° C
Phase number: single-phase rated temperature: ≤1000°C furnace size: length 300×width 200×height 120 (mm)
Empty furnace heating time: ≤15min Dimensions: length 560 × width 410 × height 560 (mm)
Empty furnace loss power: ≤0.5KW
III. Structure Introduction The resistance furnace is a furnace-controlled integrated type. The outer casing is made of steel plate and welded. The surface of the outer casing is electrostatically sprayed, and the paint film is beautiful and firm. The furnace is an integral whole fiber structure of the furnace mouth and the furnace, the electric heating wire is embedded in the furnace, the air heat insulation structure is adopted in the furnace body and the outer shell, the surface temperature rise is low, the working environment is good, the structure is reasonable, and the use and maintenance are convenient.
Fourth, the installation and use method 1. First check whether the electric furnace complete system is intact. Read the instructions and the certificate is complete, read the instructions carefully.
2. Place the electric stove horizontally on the workbench and connect the power cord to the power supply. Pay attention to the wiring markings of the wires when connecting.
3. The furnace shell should have a reliable protective grounding to ensure safe use.
4. When the electric furnace is used for the first time or for a long time, it must be dried by the oven. Oven method: set the temperature at 200 ° C, work for 4 hours (slightly open the furnace door, let go of moisture). Set the temperature to 600 ° C, work for 4 hours, after the oven is completed, the electric furnace can be put into normal use.
V. Maintenance and safety precautions 1. During the operation of the electric furnace, the temperature inside the furnace is strictly prohibited to exceed 1000 °C. In order to prolong the service life, the long-term working temperature should be 50 °C lower than the rated temperature.
2. The number of times the furnace door is opened should be reduced during the work to avoid the temperature in the furnace being quenched and hot, and the furnace is protected.
3. The furnace door should be lightly opened and lightly closed. The workpiece should be handled gently and gently to avoid damage to the furnace mouth and furnace. When handling the heated workpiece, the power should be cut off to ensure personal safety.
4. When the thermocouple or temperature control instrument is damaged, when it needs to be replaced, it should be ensured that the thermocouple is consistent with the temperature control instrument. Otherwise, the furnace temperature will be inconsistent with the temperature displayed by the temperature control instrument. In severe cases, the electric furnace will be burned. .
5. It is forbidden to directly inject liquid into the furnace, and often clean the iron filings and oxide scale in the furnace to keep the furnace clean.
6. The electric furnace shall not be placed in an environment with strong magnetic field, strong corrosive gas, large amount of dust and vibrating or explosive gas. The ambient temperature is 5~40 °C, and the relative humidity is not more than 80%.
