Tandem melting furnace

? ? ? ? Tandem melting furnaceIt adopts the "series inverter thyristor intermediate frequency power supply technology" and is professionally designed and manufactured by Shaanxi Haishan Mechanical and Electrical Co., Ltd. Its structure is based on an intermediate frequency melting furnace and is mainly used for metal smelting in the foundry industry. here,Haishan electric furnaceThe editor introduces this product from the following aspects:Tandem melting furnace。

1. Overview of series one to two medium frequency electric furnaces
? ? ?Tandem melting furnaceIt is an intermediate frequency power supply with two furnaces working at the same time. The total smelting power can be distributed arbitrarily between the two furnaces. It can realize one smelting furnace and one holding furnace, uninterrupted smelting, and can maintain and heat up at accurate temperatures when needed. , conditioning and tempering, etc., to maximize production volume.

two,Tandem melting furnaceskills requirement

? ? ? 1、Tandem melting furnaceThe technology of series inverter thyristor intermediate frequency power supply should be adopted to meet the demand of high power factor.

? ? ? 2、Tandem melting furnaceThe power supply should be placed between the two furnace bodies to ensure that the distance between the power supply and the center of the two furnace bodies is equal.

? ? ? 3、Tandem melting furnaceEach furnace needs to be equipped with an induction coil, and the number of coil turns is determined according to the specific specifications of each furnace.

? ? ? 4、Tandem melting furnaceThe power supply should adopt three-phase five-wire system 380V, 50HZ industrial power, equipped with 6-pulse single rectifier intermediate frequency power supply.

? ? ?5、Tandem melting furnaceThe transformer capacity is relatively small. Compared with the parallel medium frequency smelting furnace, the cost of increasing the transformer capacity can be saved.

three,Tandem melting furnaceTechnical features
1. High power factor: Through the digital shift trigger circuit, the rectifier control circuit can maintain a high power factor.

2. High load voltage: Although the thyristor fully controlled rectifier electric furnace is not used for voltage regulation, it can be used as an electronic switch to quickly cut off the power supply in case of failure.

3. Small loss: During normal operation, the thyristor is always in a fully conductive state, so that the power supply of the power grid has a high power factor and reduces harmonic interference.

4. Power supply for multiple furnaces: theTandem melting furnaceOne set of power supply can supply power to two (more) furnaces at the same time, and the output power can be distributed arbitrarily between the two (more) furnaces.

5. Synchronous melting and heat preservation: Two (more) furnace bodies can be melted or heat-preserved at the same time, which is suitable for the requirements of large-scale molding production lines for uninterrupted molten iron dispensing.

Four,Tandem melting furnaceComposition:

? ? ? 1、Tandem melting furnaceFurnace body: The furnace body is the main component of the smelting furnace. It is made of refractory materials. Generally, graphite, magnesium oxide and other materials are used. The structure of the furnace body can be round or square, and electrodes can be added as needed.

? ? ? 2、Tandem melting furnacePower supply: The power supply is the heart of the smelting furnace. It provides electrical energy to drive the furnace. The power supply usually uses a medium frequency power supply, which can provide stable power output.

3. Control system: The control system is the brain of the smelting furnace. It controls various operations of the furnace, such as heating, heat preservation, etc. The control system usually includes temperature sensors, liquid level sensors, etc., which can monitor and control the working status of the furnace in real time.

4. Cooling system: The smelting furnace will generate a large amount of heat during operation, and the cooling system can effectively dissipate this heat to ensure the normal operation of the furnace.

five,Tandem melting furnacesafe operating procedures

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 loss in a Haishan electric furnace.

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. The pounding of the Haishan electric furnace 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 the molten steel from falling to the ground and exploding.
7. The molten steel is not allowed to be filled too full. When pouring the hand bag, the two people should cooperate in unison and walk smoothly. No sudden stops are allowed. After pouring, the remaining steel must be poured into the designated place. It is strictly forbidden to dump it randomly.
? ? ? ? 8、Tandem melting furnaceThe power supply room should be kept clean. Inflammable and explosive items and other debris are strictly prohibited from being brought into the room. Smoking is prohibited indoors.
