1. The metal melting furnace process is more stable, and the castings have higher mechanical strength. In the induction furnace can be melted in various compositions of iron, due to the melting process of oxidation lossless, and can be more convenient to adjust the composition and temperature of the iron liquid, the final quality of the iron liquid obtained is more stable. In recent years, new processes for the production of high-strength and low-stress castings have emerged abroad. The method is to use 40% to 80% of scrap steel in the ingredients, first obtain low-carbon raw molten iron, then heat it to 1450°C for decarburization, and make the chemical composition reach the value specified in the process, and then overheat the molten iron to keep the temperature at 1500～1550℃ for 10～30min, and strictly control the crystallization supercooling degree of the molten iron. 2. The use of induction furnaces for melting non-ferrous metals can reduce melt burnout or achieve oxidation-free melting, such as aluminium induction melting furnaces, copper induction melting furnaces and zinc melting furnaces. 3. The use of induction melting furnaces reduces environmental pollution. Because the induction electric furnace does not have energy carriers of combustion products, the discharge of...
Option A: The raw material is scrap, which needs to start with scrap steel melting. The first step is to melt the scrap steel in an induction melting furnace; the second step is to cast the billet through a column mold or CCM; the third step is to reheat the billet in an induction heating furnace, and finally to enter a horizontal rolling mill or continuous rolling mill. Option B: The raw material is billet, which we can heat directly in a reheating furnace and then feed into a rolling mill to be rolled into a rebar or other profiles of steel. As you can see, the billet-to-rebar production option saves more power and investment, so if you don’t want to invest too much in the first stage or don’t have enough power, then option B small mini rolling mill from billet to steel rebar is a better option. And if we have a lot of raw scraps and want a larger capacity rebar production line, plan A would be better. In general, plan A is more thermally efficient because the billet is still hot when it has just been cast from CCM and this will save electricity. Some continuous...
Normally there are 3 steps for steel bar production line: 1. Melting scrap steel as liquid and casting billet, the equipment in this step we need is: Industrial induction melting furnace(melting steel as liquid), closed water cooling tower(cooling the melting furnace), transformer(transfer the electricity from high side voltage to equipment voltage), and billet mold or CCM continuous casting machine ( to casting standard billet size) 2. Heating the billets to 1250 degrees. Here we need: Billet heating furnace(reheating billet) and closed water cooling tower(cooling the induction heating furnace) 3. Processing hot billets to steel rebar, here we need Hot rolling mill group(rough rolling mill, continuous rolling mills), auxiliary equipment like roller conveyor, Shear, cooling bed, and packing table, etc Here are some videos of our products for your understanding and reference, hope they can bring you help. https://www.youtube.com/watch?v=9bI_8R81ELs
Now steel billet hot rolling is generally adopted in steel rolling workshops. The advantage of direct hot rolling of billets: 1. To reduce the power consumption of the induction heating furnace, save a lot of energy, reduce heating time, and reduce metal consumption. Generally, the metal consumption is reduced by 0.3% compared with cold charging. 2. To reduce construction investment and production costs, and shorten the production cycle. The conditions for the direct hot charging of billets are: 1, The steel-making workshop should have the necessary equipment and technology to ensure the production of defect-free blanks and a stable and balanced production process. 2, Steelmaking and steel rolling mill should be organized according to a certain production plan, and maintenance should be carried out in accordance with a unified plan as much as possible. 3, The continuous casting machine should match the hourly output of the rolling mill machine properly. 4, In order to give the full effect of hot charging, even if the rolling mill stops production for a short time, no cold billet will be produced. A buffer zone should be set up between the roller table and the heating furnace. 5, The heating furnace should be able...
We usually classify hot rolling mills into rough rolling mills, horizontal rolling mills, and continuous rolling mills. Rough rolling mill: they have a high rolling capacity and are generally used for the initial rolling of billets, which can be processed 5-7 times, helping customers to save equipment costs. Horizontal rolling mil: generally consist of one motor drive several reversible rolling mill stands and one 2 rollers rolling mill stand at the end. It is used for a 1-3T per hour small capacity rebar production line. Advantages are low initial investment costs, quick return on capital, low electricity consumption, low maintenance costs, and small factory area requirements. The disadvantage is a large amount of manual operation and the small output. Continuous rolling mill: divided into one motor drive one stand rolling mill and one motor drive 2 stands rolling mill. The advantage is the high degree of automation, the use of less labor, generally suitable for large capacity rolling mill production lines. The disadvantage is that there are too many motors, which use a lot of electricity and require a large transformer. In addition to this, it requires many roles, which are costly to use, has high maintenance costs, and requires...
Some customers wanna know if we setting a foundry plant, which kind of casting equipment do we need? For a full set foundry plant workshop, here is the metal casting equipment list we need : 1. Induction melting furnace: To melt scrap metal as liquid. 2. Steel ladle: To transfer the steel liquid to workpiece mold. 3. Sand mixing machine: To mix the foundry using sand. 4. Sand molding machine: To help workers make workpiece sand mold. 5. Shot blasting machine: To process the workpiece, making the appearance more smoothly. Then how about the application? What kind of metal casting is this foundry line suitable for? Here are some examples: Manhole cover, Small pipe joints, Iron Fence, Hammer, Some shells like reducer shells, motor shells, Gears, etc. We also can design the mold for customers according to the customer’s drawing. Hongteng can adopt the full foundry line for customers, welcome contact us! Here are some videos of metal casting for your understanding and reference, hope they can bring you help. https://www.youtube.com/watch?v=xmbc6GSdjmQ
