High-frequency heating machines can perform surface heat treatment on industrial metal parts such as surface quenching, metal melting, rod heat transfer, tool welding, etc.It is necessary to choose a suitable high-frequency heating machine.For better results, it is necessary during operation.Pay attention to the operation of the high-frequency heating machine.Compared with previous heating machines, high-frequency heating machines have the following four advantages: 1. High-frequency heating machines are more energy-saving and environmentally friendly: it is a reform of the heating method. It also has an electric heating function, but compared with electric furnaces, etc., it can Save 40% of electrical energy.2. The performance of the high-frequency heating machine meets various needs: it can instantly heat metal objects to any required temperature, including its melting point.3. The high-frequency heating machine is more efficient: it does not need to generate high temperature first and then heat the metal object heated by it like other heating methods. It can directly generate high temperature in the metal.4. The high-frequency heating machine can achieve precise control: not only can the metal object be heated as a whole, but also each part can be heated. Read More

In the production process of using smelting furnaces to smelt metal, a large amount of waste slag, waste gas, waste water and dust will be generated.If it is discharged directly, it will not only cause environmental pollution and waste resources, but also endanger people's health.Therefore, the three wastes should be processed and recycled.1. Treatment of waste slag 1. Direct recycling 2. Use quenched slag with water to directly make cement raw materials 3. Use slag to make cast stone 4. Use waste slag to make construction and road construction materials and farmland fertilizer 2. Treatment and utilization of waste gas 1. Exposure Electric furnace flue gas purification 2. Semi-closed electric furnace 3. Closed electric furnace flue gas purification and energy recovery 4. Comprehensive utilization of smoke and dust 3. Wastewater treatment and application Ferroalloy production wet dust removal (Venuri scrubber) will produce a large amount of sewage, sewage It contains a variety of harmful substances, and direct discharge will definitely pollute the environment and waste water resources.Purifying it can not only protect the environment, but also recycle water, killing two birds with one stone.Currently, countries around the world Read More

The smelting furnace is a very dangerous equipment, and the temperature can be said to be very high. We must pay attention to safety during production operations!Below I will briefly introduce to you some issues that should be paid attention to in the actual operation of the smelting furnace.1. Before starting the furnace, check whether the electrical equipment, water cooling system, sensor copper tubes, etc. are intact, otherwise it is prohibited to open the furnace.2. If the melting loss of the furnace exceeds the regulations, it should be repaired in time.It is strictly prohibited to smelt in a crucible with excessive melting damage.3. There should be a dedicated person responsible for powering on and starting the furnace. It is strictly forbidden to touch the sensor and cable after powering on.Personnel on duty are not allowed to leave their posts without authorization and must pay attention to the external conditions of the sensor and crucible.4. When charging, check whether there are flammable, explosive and other harmful items mixed in the charge. If any, they should be removed in time. It is strictly forbidden to add cold materials and wet materials directly into the molten steel. It is strictly forbidden to add large pieces of materials after the molten liquid is filled to the top. , to prevent capping.5. When repairing the furnace and pounding the crucible, it is strictly forbidden to mix iron filings and iron oxide, and the pounding of the crucible must be dense.6. pour Read More
