Luoyang HongtengIntermediate frequency induction furnace
Many friends will probably think again before buying a melting furnace, “What size furnace do I need?” In fact, there are two ways to quickly find the furnace you want The first way is based on how much you want to produce per hour. When you know how much you can produce per hour, choose the same melting furnace as you want. For example, if you want to melt 2 tons of scrap in an hour, you choose a 2-ton furnace. Because under normal circumstances, melting furnace melting time is about 1 hour The second method is based on how much waste you want to melt at one time. When you want to melt 500kg of scrap at a time, you choose a 500kg furnace
1. The principle of intermediate frequency heating furnace is based on electromagnetic induction heating, following the effect theory of electromagnetic, such as electromagnetic ring effect, skin effect, sharp corner effect, proximity effect, diathermic effect, conduction effect, and so on. 2, Intermediate frequency heating furnace is mainly composed of frequency conversion device and induction coil, frequency conversion device will power frequency 50Hz alternating current into if 100Hz– 10000H alternating current, the three-phase power frequency alternating current into direct current after rectification, and then the direct current into adjustable if current, supply by the capacitor and the induction coil flow in the intermediate frequency alternating current, High-density magnetic field lines are generated in the induction ring, and the metal materials stored in the induction ring are cut to produce a large eddy current in the metal materials. 3. The frequency conversion device and induction coil of the intermediate frequency heating furnace make the heated metal material produce eddy current. This eddy current also has some properties of the intermediate frequency current, that is, the free electrons of the metal itself flow in the metal body with resistance to produce heat. , for example, put a metal cylinder has alternating medium frequency current...
Before changing rolls, check whether the online rolls are the rolls of the changed sorts, rolling varieties, and specifications; Scrub each sideways, roll flat head and inner hole of the sleeve, and apply clean grease after scrubbing. After the preparation work is completed, the rack can be replaced according to the roll replacement plan, and its working steps are as follows: 1. Turn off the cooling water of the rolling mill and dismantle the inlet and outlet guides. 2. Remove the water pipe joints of the upper and lower rolls. 3. Activate the hydraulic locking device for opening the rack. 4. Horizontal stand select “stand traversal” to advance the stand and move the rolling mill to the limit position on the operating side. (The vertical mill selects the “stand up/down” button to lower the stand and lower the mill to the lower limit position.) 5. Pull out the fixing pin of the flat headset bracket wrench and pull the bracket wrench to separate the flat head of the frame from the flat headset bracket. 6. Pull the “rack traversal” button of the horizontal rolling mill, Make the flat headcover bracket back, disengage the flat headcover from the roll flat head,...
Let’s start with the advantages of aluminum shell furnaces: 1. Simple structure （reducer titling） 2. Few easy-wearing parts than steel shell 3. Low operating cost of works 4. Investment is low 5. Low post-maintenance cost 6. 80% of customers buy aluminum shells Now, The advantages of steel shell furnaces： 1. Complicated structure （hydraulic titling） 2. Energy saving 3. More stable and durable 4. We recommend you the steel shell when the required capacity is more than 5tons
Normally there are 3 steps for rebar making: 1. Melting scrap steel as liquid and casting Billet- in this step the equipment we need is : A: Induction melting furnace- melting steel as liquid B: Closed water cooling tower- cooling the melting furnace C: Transformer- transfer the electricity from high side voltage to equipment voltage; D: Billet molds- to form standard steel billet size 2. Heating the billet to 1250 degrees. Here we need A: Heating furnace – Reheating billet B: Closed water cooling tower- cooling the melting furnace 3. Processing hot billet to rebar, here we need: A: Hot rolling mill group B: Auxiliary equipment: roller conveyor, shear, cooling bed, etc
In the use process of induction heating furnace, if you do not pay attention to maintenance, it will often cause unnecessary troubles. The following is a brief analysis of several commonly used methods for maintaining intermediate frequency furnaces. 1. Regularly clean the dust in the power cabinet, especially the outside of the SCR die. It is necessary to wipe clean the inverter device in operation with alcohol, but the actual working environment is not ideal. In the smelting and forging process, the dust is very large and vibrates strongly; in the intermediate frequency furnace diathermic quenching process, the device is often close to the pickling and phosphating operation equipment, and there are more corrosive gases, which will damage the components of the device and reduce the device. The dielectric strength. When there is a lot of dust, the surface discharge phenomenon of the components often occurs, so it is necessary to pay attention to frequent cleaning work to prevent malfunctions. 2. Regularly check whether the water pipe joints are tightly tied. When using tap water well water as the cooling water source of the device, it is easy to accumulate scale and affect the cooling effect. When the plastic water...
