With the wide application of forgings, heat treatment, quenching and tempering and carburizing and quenching are two commonly used heat treatment methods. Heat treatment is a key process to improve the strength and toughness of various forgings. A large amount of energy is required in production to improve the surface and internal structure of forgings to obtain the required performance. Due to many reasons, the overall production efficiency of heat treatment in domestic forging plants is relatively low, and sustainable development must be pursued for healthy development. In heat treatment of forging plants, reducing energy consumption and realizing energy saving and efficiency is the only way.

Front View of 300mm 350mm Railroad Train Wheels , Crane Rail Wheels Cast Steel Material:
Almost all train wheels have a curved projection, a flange, on one side to keep the wheels, and hence the train, running on the rails when the limits or tests of alignment are reached.
What are the blanking methods in the forging plant? The introduction of common blanking methods, the forging factory has a variety of different blanking methods, such as grinding wheel cutting method, breaking method, EDM cutting and other different blanking methods, and different blanking methods have different advantages. Disadvantages, we should choose the appropriate blanking method according to the characteristics of the forging.
The forging factory needs to heat the steel raw materials before forging production, and cut the raw materials into reasonable lengths, which is called blanking. Usually, the free forging method is used to open the billet, and then the raw materials (ingots and billets) are cut in two forgings, and the billets are divided according to a certain size for heating
1. Grinding wheel cutting method:
It is suitable for cutting small-section bars, tubes with special-shaped sections, and other metals that are difficult to cut by blanking methods, such as superalloy GH33, GH37, etc. The advantages are that the equipment is simple, the operation is convenient, the cutting length is accurate, the quality of the end face is good, the productivity is higher than that of the saw blade small material but lower than that of cutting a cold folded material, the grinding wheel consumption is large, and it is fragile and noisy.
2. the breaking method:
(Also called cold folding method) Its working principle: Now a small gap is opened at the place to be broken, and under the pressure F, stress concentration is generated at the gap to break the blank. The reason is that when the average stress in the blank reaches the yield limit, the local stress at the notch has already exceeded the strength limit, so the blank has broken before plastic deformation.
3. EDM cutting:
Its working principle is: the DC motor connects the blank to the positive electrode and the negative electrode through the resistor R and the capacitor C, and cuts it in the electrolyte. The pulse current intensity of the electric spark is very large, reaching hundreds or thousands of amperes; tens of thousands of watts. And the contact area at the cut is very small, so the current density may be as high as hundreds of thousands of A/mm2. Therefore, the local temperature on the blank is very high, about 10000 ° C, which promotes the melting of the metal to achieve the purpose of blanking.
Other cutting methods include friction sawing, electromechanical sawing, anode mechanical cutting, electric spark cutting, and precision cutting.
What are the blanking methods in the forging plant? The common blanking methods are introduced. There are many blanking methods for forging production and processing, such as grinding wheel cutting method, breaking method, EDM cutting, etc. We should choose suitable forgings according to the process characteristics of forgings material method.
What is the function of free forging upsetting process? Introduction of upsetting process, forging upsetting treatment is one of the commonly used production processes in free forging, mainly under the action of external force, reducing the height of the forging leather and increasing the cross-sectional area of the forging process, Upsetting of forgings can obtain forgings with larger cross-sectional area and smaller height, which can be used in the preparation process before punching, and increase the cross-sectional area of forging blanks to facilitate punching and other operations.
The upsetting process in the forging factory is a kind of forging production process. It is a forging process that reduces the height of the blank of the forging and increases the cross-section under the action of external force.
1. The role of upsetting:
1. Obtain forgings with larger cross-section and smaller height;
2. It is used as a preparation process before punching, and the cross-sectional area of the blank of the forging is increased to facilitate punching;
3. Repeated upsetting and drawing method, the combination of upsetting and drawing length can improve the forging ratio, at the same time crush the massive carbides in the alloy tool steel, and make them evenly distributed to improve the performance of the forgings;
4. Improve the transverse mechanical properties of forgings to reduce the anisotropy of mechanical properties.
2. The main method of upsetting;
Flat anvil upsetting, gasket upsetting and partial upsetting produced by the forging factory. The upsetting of blanks with different height-diameter ratios, and the shape and size of the blanks also affect the uneven deformation during upsetting.
3. Measures that can be taken to reduce defects include:
① The forging factory uses lubrication and preheating tools;
②, upsetting with side concave blank;
③, use a soft metal pad for upsetting;
④, stack upsetting.
What is the function of the free forging upsetting process? The upsetting process is introduced. The forging upsetting process mainly includes flat anvil upsetting, gasket upsetting and local upsetting. The upsetting of blanks with different height-diameter ratios, and the shape and size of the blanks also affect the uneven deformation during upsetting. We should choose a suitable upsetting process according to the shape and performance of the forging.
What are the energy-saving measures for heat treatment in forging plants? The main energy-saving measures for heat treatment in forging plants are to improve heat treatment process, tap heat treatment potential, reasonably shorten production cycle, reduce energy consumption, etc. to save energy, adopt advanced heat treatment equipment with low energy consumption, continuous Production, formulate a reasonable heat treatment process, do a good job in equipment maintenance, etc. Among many energy-saving means, process optimization is one of the effective means to achieve energy-saving and efficiency without investing a lot of money.
Energy saving and efficiency enhancement is an important part of the optimization of the heat treatment process of the forging plant, and it is also one of the effective means of energy saving and consumption reduction in the forging plant. Production cycle, reduce energy consumption to achieve economic benefits.
Heat treatment in a forging factory is to heat the forging to a certain temperature, keep it for a period of time, and then adopt different cooling rates to obtain different microstructures. The heat treatment only changes the internal structure of the forging, not the shape of the forging. The method of heat treatment to save energy and increase efficiency is to shorten the production cycle and save energy and reduce consumption by changing parameters such as heating temperature, holding time, and cooling method on the premise of ensuring internal performance. Forging as a traditional industry, forging forging plant is a major energy consumer, mainly reflected in the consumption of electric energy. In the field of forging product manufacturing, electric energy saving is an intuitive energy-saving direction. Energy saving can be achieved through different measures, such as adopting advanced heat treatment equipment with low energy consumption, continuous production, formulating reasonable heat treatment processes, and maintaining equipment well. Among many energy-saving means, process optimization is one of the effective means to achieve energy-saving and efficiency-enhancing without investing a lot of money.
