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

2.The online speed is relatively high at 15m/min, with a speed adjustment range of 9-15mm/min. The speed of each steel billet is constant.

3. Temperature distribution

The distribution characteristics of temperature zones in the cross-section of continuous casting billets indicate that the internal temperature belongs to the high-temperature zone, with a temperature of 1100 ℃; The external area is a low-temperature zone with a temperature of 800 ℃, which is the part that needs to be raised by 300 ℃.

The temperature distribution characteristics of the damaged head and tail of continuous casting are usually about 50 ° C lower than that of the tail.

The relationship between furnace temperature and steel oxidation rate:

Temperature ('C) 200 400 600 800 1000 1200

The oxidation amount (g.cm-2) is 0.00266 0.759 16.26 111.1 414.9 1083. From the above table, it can be seen that the higher the heating temperature, the more severe the oxidation. Steel failure begins to generate iron oxide scale at 600-700 ℃; When the temperature is between 900-1000 ℃, the oxidation rate accelerates and the oxide scale thickens: when the steel temperature is above 1200 ℃, the oxidation rate is 10 times that of 800 ℃. Therefore, preventing steel from being heated at excessively high temperatures is an important measure to reduce the oxidation of steel billets

1. Power supply system: Dual rectifier 12 pulse or 24 pulse KGPS1000-1000KW, single medium frequency power supply can be used independently or multiple power supplies can be used in parallel. Install specialized transformers on the equipment to reduce the impact of harmonics on the power grid. Users can use it with confidence, safe and reliable.

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 designed for standalone use, with a specially customized human-machine interface, highly user-friendly operation instructions, fully digital and deep adjustable parameters, and a one click restore function. It is easy to operate.

4. Power supply requirements: Dual power transformers, 12 pulse rectifier power supply, capable of infinitely reducing harmonic pollution and improving work efficiency.

5. Feeding and guiding system: Each axis is driven by an independent motor reducer, with multiple axis drives and a single frequency converter control to synchronize the operation of multiple axes. The components are selected from well-known brands, with reliable quality and stable operation. Using 304 non-magnetic stainless steel guide wheels, the axial elasticity of the guide wheels is maintained to adapt to the allowable bending range of the steel billet. 6. All cabinets are sandblasted, sprayed with plastic, and baked with paint. All waterways are made of thick walled stainless steel. The continuous casting steel billet heating electric furnace is corrosion-resistant and has a long service life. The equipment is equipped with a large LCD temperature display screen (which is convenient for on-site personnel to observe and display data).

7. The use of American Leitai temperature measuring device ensures uniform temperature heating and no deformation or cracking of the billet.
