Welcome to visit the factory and negotiate business!

The reheating furnace for steel billets is controlled by an intermediate frequency power supply, which has the following characteristics:

1. Constant power output, fast heating speed: An intermediate frequency power supply is a true constant power output power supply. Adding a small amount of material can achieve rated power output, and it always remains unchanged. The reverse frequency converter tracks load changes at all times, achieving complete resonance protection for constant power output. It is different from the thyristor intermediate frequency power regulation method, where the thyristor intermediate frequency power supply adjusts the DC output voltage. IGBT intermediate frequency power supply products regulate frequency and are not affected by furnace materials. Throughout the entire heating process, constant power output is maintained, especially in the production of non magnetic substances such as stainless steel, copper, and aluminum, which demonstrates its advantages such as fast melting speed, low burning loss of furnace elements, and reduced casting costs. So the smelting speed is fast, thereby achieving high efficiency and energy conservation.

2. No high order harmonic interference: High order harmonics mainly come from the burr voltage generated by the controllable silicon during the voltage regulation of the rectifier section, which can seriously pollute the power grid and cause other equipment to not work properly. However, energy-saving IGBT intermediate frequency power supply is a voltage type inverter, and the rectifier section adopts full bridge rectification. The rectifier thyristor will be fully conductive, and the IGBT intermediate frequency adopts frequency modulation and power regulation, inductance and capacitor filtering, and has been working at 500V, The power factor reaches 0.98 or above, and the rectifier circuit uses thyristors to achieve soft start and stop. Due to the full conduction of the thyristors during normal operation, the DC voltage always works at a high level without adjusting the conduction angle, and there is no significant current impact during start and stop. Therefore, high order harmonics are minimal, and do not pollute the power grid or interfere with the operation of electronic equipment in the factory.

3. High startup power: Due to the use of series inverter technology, it is easy to start and completely solves the problem of difficulty in starting the thyristor at intermediate frequency. Reliable and frequent startup can be achieved, with a high success rate of startup.

4. The product has high reliability: The main components of the IGBT intermediate frequency power supply are all made by world-renowned factories, and the IGBT transistor is produced by Siemens in Germany. This product has mature technology, reasonable results, convenient debugging and maintenance, and reliable performance. It is also equipped with various fast automatic protection functions such as water pressure, water temperature, phase loss, overcurrent, undervoltage, and repeated startup, ensuring stable and reliable operation of the modified product.

5. The product has high stability: Our company's IGBT medium frequency power supply products use components produced by international brand companies. The cooling system of the product adopts internal circulation cooling, and the internal circulation uses softened water. The water path in the induction heating furnace for steel billets is not scaled or blocked for long-term use, and the equipment is equipped with air conditioning. The components always work at the appropriate temperature, greatly reducing the failure rate, ensuring the stability of the entire machine, and saving maintenance costs.

Advantages of Steel Ball Rolling Equipment

 Introduction to Steel Ball Classification: The production process of steel balls can be divided into two categories: casting and forging, while the forging production process can be divided into two categories: forging and rolling. Forging and rolling are collectively referred to as forging and rolling. Air hammers are usually forged with steel balls. hot rolled steel ball machine, also known as steel ball skew rolling, is carried out on a skew rolling mill. The cross rolling forming process has a history of several decades, but it has been widely used in the production of steel grinding balls in the past decade.

Briefly introduced the advantages of the steel ball hot rolling machine in producing steel balls:

1. The production line of hot-rolled steel balls produces a high output of rolled steel balls, especially the production efficiency of rolled steel balls, which is incomparable to cast steel balls. Forging production is twice that of casting production, while rolling production is more than a few dozen times that of casting production.

2. There are two main reasons for the high quality of rolled steel balls in the hot rolling steel ball production line: one is the rolled products, and the metal fiber is streamline; The second is grain refinement after rolling. These two points are also the reason for the high impact toughness and tensile strength of steel balls.

3. The rolling production of hot rolled steel balls on the production line is a type of rolling steel balls with good labor conditions. If induction heating and automation are adopted, the labor conditions of the cutting production line will be greatly improved. Reduce labor intensity and improve the working environment.

Forever Electromechanical has produced nearly 200 Steel ball rolling equipment nationwide and even around the world. The heating diameter of the steel rod is 20-300, and the length of the steel rod is generally not limited to 6 meters or more. PLC closed-loop control automatic heating production line can be achieved according to customer needs. PLC automatic control can achieve automatic temperature adjustment and automatically track power based on the speed of the hot rolled steel ball production line. The induction heating equipment adopts network power control, with low power consumption and high production efficiency.

We also have many other furnaces, such as Forging heating furnace 、pipe induction heating equipment 、Hot rolled steel ball 、steel bar quenching and tempering furnace and so on.

continuous casting billet heating furnace manufacurter & supplier

 Process parameters of continuous casting billet heating furnace:

1. Continuous casting billet size: 6000 (length)× 150 (width) - 150 (thickness)

2. The online speed is higher than 15m/min, and the speed adjustment range is 9~15m/min. The speed of each billet is constant.

3. Temperature distribution

(1) The temperature distribution characteristics of the cross section of the continuous casting billet are as follows: the internal temperature belongs to the high temperature region, with a temperature of 1100 ℃; The outside is a low temperature zone with a temperature of 800 ℃, and the low temperature zone is the part that needs to be raised by 300 ℃.

(2) The temperature distribution characteristics of the head and tail of the continuous casting billet are generally about 50 ℃ lower than the tail temperature.

Relationship between furnace temperature and billet oxidation amount:

Temperature (℃) 200 400 600 800 1000 1200

Oxidation amount (g.cm-2) 0.00266 0.759 16.26 111.1 414.9 1083

From the table above, it can be seen that the higher the heating temperature, the more intense the oxidation. The steel billet begins to form iron oxide scales at 600-700 ℃; When the temperature is between 900 and 1000 ℃, the oxidation speed increases and the oxide scale becomes thicker; When the steel temperature is higher than 1200 ℃, the oxidation rate is 10 times that of 800 ℃. Therefore, preventing steel from heating at excessively high temperatures is an important measure to reduce billet oxidation.

Characteristics of continuous casting billet heating furnace:

1. Power supply system: Double rectified 12 pulse or 24 pulse KGPS1000-1000KW single intermediate frequency power supply used independently or multiple power supplies used in parallel. The equipment is installed with dedicated transformers to reduce the impact of harmonics on the power grid. Users can use it safely and reliably.

2. Surface temperature before entering the furnace: 850 ℃

3. Control system: The entire heating process is automatically controlled by PLC, and production records such as heating quantity are displayed in a timely manner. This console is used alone, with a specially customized human-computer interface, highly user-friendly operation instructions, fully digital, high-depth adjustable parameters, and a one-button restore function, making it easy to operate.

4. Power supply requirements: Dual power supply transformers, 12 pulse rectifier power supply, which can infinitely reduce harmonic pollution and improve work efficiency.

5. Feeding and guiding system: Each shaft is driven by an independent motor reducer, equipped with a multi shaft drive, and controlled by a single frequency converter to synchronize the multi shaft operation. The components are selected from well-known brands, with reliable quality and stable operation. 304 non magnetic stainless steel guide wheel is used to maintain moderate axial elasticity of the guide wheel to adapt to the bending of the steel billet within the allowable range.

6. The cabinet is made of sand blasting, plastic spraying, and baking paint. The waterways are all thick walled stainless steel. The continuous casting billet heating furnace is corrosion resistant and has a long service life. The equipment is equipped with a large LCD temperature display screen (convenient for on-site personnel to observe and display data).

7. The use of the American Raytheon temperature measuring device ensures uniform temperature heating and no deformation and cracks in the blank.
