يستخدم فرن الحث مبدأ الحث الكهرومغناطيسي لتسخين المعدن, الذي ينتمي إلى نوع من معدات التسخين الحثية غير المتصلة في تسخين المعادن. بسبب سرعة تسخينه السريعة, درجة حرارة التدفئة موحدة, توفير الطاقة وحماية البيئة, عملية سهلة, فقدان أقل للأكسدة, and wide application range are deeply loved by people in the metal heating industry. لكن, there are three different heating forms in the فرن الصهر التعريفي: electric induction furnace metal heating, electrothern induction furnace metal melting, and induction furnace metal tempering. لذا, what are the differences among the three uses of induction melting furnaces?
1. Induction furnace metal heating
Induction melting furnace is often used for heating before forging, metal rolling, gear blank, connecting rod blank, shaft blank, plate blank, tube blank, إلخ; The heating temperature is generally less than 1250 درجات, and different heating power is selected according to the heating beat, heating temperature, وغيرها من المعلمات; The heated metal materials are alloy steel, aluminum alloy, سبائك النحاس, الفولاذ المقاوم للصدأ, titanium alloy, إلخ; The equipment is composed of automatic feeding system, medium frequency power supply, inductor, discharging system, temperature measuring system, cooling system, إلخ.
2. Induction furnace metal smelting
Induction melting furnace is often used for smelting scrap metals in the foundry industry. The melting temperature is 1700 درجات, and the power of the smelting furnace is determined according to the melting temperature, melting metal material and melting time; The smelting waste metal materials include alloy steel, aluminum alloy, الفولاذ المقاوم للصدأ, سبائك النحاس, gold, silver and other metal materials; The equipment consists of medium frequency power supply, smelting furnace body, tilting mechanism, induction coil, water cooling cable, capacitor cabinet and cooling system.
3. Inductionfurnace metal quenching and tempering
Induction melting furnace metal quenching and tempering is the application of the equipment in heat treatment heating. It is commonly used for metal quenching, هدأ, annealing and normalizing heating. According to different heat treatment process requirements, it can be heated to different temperatures, equipped with a water spray cooling device or extended cooling time to meet the quenching and tempering process requirements. The heating temperature ranges from 100 ℃ to 1200 ℃, The quenched and tempered metal material is generally round steel alloy steel; The equipment consists of feeding mechanism, conveying mechanism, quenching heating system of foundry melting furnace, water spraying cold zone device, tempering heating system, discharging system, temperature measurement system, PLC control system, إلخ.
There are many kinds of induction furnace heating uses, but the subdivision is no more than the three types described above. These three uses of melting furnaces basically cover the heating range of the equipment. لذلك, it is particularly important to distinguish the uses of intermediate frequency furnaces when selecting medium frequency furnaces.
