Structure introduction and correct operation method of Hunan smelting furnace
The smelting furnace is mainly used to warm and smelt precious metals, such as gold and aluminum alloys. It also has the characteristics of energy saving and is the best choice for processing. Today, Kehua shared with my dear friends the structure of the smelting furnace in Hunan. Introduction and correct operation method. Hunan Melting Furnace Structure Introduction The complete set of melting furnace (Rong Gang Lu) electric furnace equipment includes intermediate frequency power supply cabinet, compensation capacitor, furnace body (two), water-cooled cable and reducer. The furnace body is composed of four parts: furnace shell, induction coil, furnace lining, and tilting furnace reduction box. The furnace shell is made of non-magnetic materials. The induction coil is a spiral-shaped cylinder made of rectangular hollow tubes. Cooling water is passed through the tubes during melting. . The copper bar drawn out of the coil is connected with the water-cooled cable, the furnace lining is close to the induction coil, and is made of quartz sand and is sintered. The tilting of the furnace body is directly rotated by the tilting furnace reduction box. The tilting furnace reduction box is a two-stage turbo speed change, with good self-locking performance, stable and reliable rotation, and when an emergency power failure occurs, the furnace can be stopped and tilted to avoid danger. The furnace selection switch can be used to select the control of the tilting reduction box motors of the two furnace bodies. The switch box with four-core rubber wire enables the operator to stand in a suitable position to control the tilting and resetting of the furnace body. At present, the above-mentioned mechanism is no longer used in the melting furnace of more than 3 tons. The tilting furnace is mainly hydraulic cylinder, and there are several evenly distributed arc-shaped magnetic yokes outside the induction copper ring to prevent magnetic flux leakage. With this method, the furnace shell does not need to be made of non-magnetic materials, and the outside of the furnace shell does not get hot. The hydraulic tilting device is used to tilt the furnace smoothly and safely. Safe operation 1. Before opening the furnace, check whether the electrical equipment, water cooling system, sensor copper pipes, etc. are in good condition, otherwise it is forbidden to open the furnace. 2. If the melting loss of the furnace exceeds the regulations, it should be repaired in time. It is strictly forbidden to smelt in the crucible with excessive melting loss. 3. A special person should be responsible for power transmission and furnace opening, and it is strictly forbidden to touch sensors and cables after power transmission. Those on duty are not allowed to leave their posts without authorization, and pay attention to the external conditions of the sensor and crucible. 4. When charging, it is necessary to check whether there are inflammable, explosive and other harmful substances mixed in the charge. If it is, it should be removed in time. It is strictly forbidden to directly add cold material and wet material into the molten steel. After the molten liquid is filled to the upper part, it is strictly forbidden to add large pieces of material. , to prevent capping. 5. It is strictly forbidden to mix iron filings and iron oxides when repairing the furnace and pounding the crucible, and the pounding crucible must be dense. 6. The pouring site and the pit in front of the furnace should be free of obstacles and water, to prevent molten steel from falling to the ground and exploding. 7. The molten steel is not allowed to be too full. When pouring the hand ladle, the two should cooperate in the same way. The walking should be stable, and emergency stops are not allowed. 8. The medium frequency generator room should be kept clean, inflammable and explosive materials and other sundries are strictly prohibited from being brought into the room, and smoking is prohibited indoors. Hunan smelting furnace The advantages of the smelting furnace are very many. In addition to the energy saving described above, it also has the advantages of simple operation and fast heating. The above is the structure introduction and correct operation method of Hunan smelting furnace shared by Kehua.
