Steel pipe heating equipment

The steel pipe heating equipment is a non-standard induction heating equipment designed and manufactured by Shaanxi Haishan Mechanical and Electrical Co., Ltd. specifically for steel pipe heating. It adopts the principle of electromagnetic induction heating and utilizes the ring heating effect and skin heating effect. The heated steel pipe heats up quickly, has good heat penetration performance, and is oxidation-resistant. Less burning loss. under,Haishan electric furnaceThe editor will give an example to introduceSteel pipe heating equipment。

one,Steel pipe heating equipmentDesign requirements:

? ? ? Steel pipe heating equipmentThe heating effect is good or bad, andSteel pipe heating equipmentThe heating power, heating productivity, heating time and heating material have a great relationship.

? ? ? Steel pipe heating equipmentThe heating power calculation formula P=C×△ T×G÷0.24×η×t

? ? ? Steel pipe heating equipmentHeating power calculation formula = 0.168 × temperature rise × heating steel pipe weight ÷ 0.24 × heating efficiency × beat

The formula: C—specific heat of billet (Kcal/Kg*℃) C=0.168

△ T - Temperature rise of the blank (°C) For example: the room temperature of the steel pipe is 25°C, and the temperature after heating is 1050°C, ΔT=1050—25=1025 (°C)

G—weight of blank per meter (Kg/m)

t —Heating time per meter of steel pipe (S/m)

η—total efficiency η=0.5

Four,Steel pipe heating equipment??Introduction to each part:

1. Power supply:Steel pipe heating equipment?Adopting KGPS medium frequency frequency conversion principle and digital circuit control, it has high reliability and high anti-interference ability.Steel pipe heating equipment?The working frequency is automatically tracked, and the load and power supply are automatically matched. Haishan electric furnace has overcurrent, overvoltage, phase loss, insufficient water pressure and other protection functions, which increases the reliability of the steel tube heating furnace and reduces the use and maintenance costs of the equipment.Steel pipe heating equipment?A temperature feedback system can be added to form a temperature closed-loop automatic adjustment system. Through a special interface, it can be controlled by PLC or "human-machine interface" industrial computer to realize intelligent control of the heating system.

2. Heating:Steel pipe heating equipment?A combined through-type induction furnace is used, with 4 combined sections. Each combined section includes an intermediate frequency power supply and a capacitor cabinet. Each low-temperature heating unit uses 2 inductors, and each high-temperature heating unit uses a transport roller. The steel pipe runs at a certain speed. The system uses two 12-pulse rectifier transformers for power supply. complete setSteel pipe heating equipmentIt is controlled by a Haishan electric furnace computer control system to meet the steel pipe heating requirements. 4 power supplies are cooled by a HSBL cooling system.

3. Machinery:Steel pipe heating equipmentThe machine consists of a furnace frame, a loading machine, a feeding mechanism, a discharging mechanism, etc. Its action setting and heating rhythm are controlled by PLC. The feeding mechanism is completed by a storage platform, a V-shaped groove in front of the furnace and a conveying device. The discharge port is equipped with a roller discharging mechanism to prevent the material from colliding with the furnace outlet. The furnace frame is a welded steel component, containing water circuits, circuits, gas circuit components, capacitor tank circuit copper bars, etc. Above is the sensor. The axis of the roller table forms an angle of 18-21 with the axis of the workpiece. The workpiece is self-propelled while advancing at a constant speed, making the heating more uniform.
