A, Steel tube heating furnace:

According to the technical requirements of the buyer, the steel pipe heating furnace we need to provide includes 1 intermediate frequency power supply, 1 compensation capacitor cabinet and 1 heating furnace body.

Process conditions and technical parameters of steel pipe heating furnace:

1. Heating temperature: 900℃～1000℃

2. External dimensions of the steel pipe: Outer diameter: Φ350mm, wall thickness 8-16mm;

Selection method of steel tube heating furnace technology

B. The intermediate frequency power supply adopts the characteristics of the latest intermediate frequency power supply developed by our company.

1. Technical indicators:

1.1, the startup success rate can reach 100%

1.2. Rectified power factor is greater than or equal to 0.92

1.3. With temperature interface, temperature closed-loop control can be realized

1.4, with internal and external conversion and automatic manual conversion function

1.5. All digital, no relay control loop, so that the system runs stably and reliably

1.6. It has complete protections such as overcurrent, overvoltage, undervoltage, lack of phase, water pressure, water temperature, etc., to ensure that any failure will not be damaged

2. તકનીકી સુવિધાઓ:

2.1, intermediate frequency power supply

2.1.1 The principle of the main circuit of the intermediate frequency power supply:

Because the power of the intermediate frequency power supply is relatively small, it is sufficient to use the 6-pulse wave, and its harmonics to the power grid will not exceed the standard. The principle of the main circuit is shown in the figure below.

C, Selection method of induction furnace body of steel tube heating furnace

Because it is sometimes necessary to replace the inductors of different specifications when heating the steel pipe. We have fully considered the convenience of quick replacement in the production of the sensor.

The heating furnace is designed with a fixed bracket that can be adjusted up and down. Through the adjustment of the manual worm gear lifter, it is possible to realize that the center lines of the heating furnaces of different specifications are at the same height. It can effectively ensure that the steel pipe smoothly passes through the inductor without hitting the furnace body.

Waterway quick change joint

In order to facilitate the operation, quick-change joints are used in the design of the water pipeline joints, as shown in the upper right figure. Its material is 316 stainless steel. It is mainly composed of threaded connector, hose connector, clasp wrench, sealing gasket, etc. The biggest feature of this kind of quick-change joint is: the threaded connector and the hose connector can be mutually matched, the fastened handle is easy to operate, and the sealing performance is good.

Furnace Lining

Furnace lining adopts silicon carbide or integral knotting method. The service temperature is above 1450℃. It has good insulation, heat insulation, shock resistance and impact resistance.

Operating conditions of steel pipe heating furnace

Intermediate frequency power supply: 380V±10% 50HZ

Required capacity of transformer: 500KW: 600KVA capacity

1000KW: 1200KVA capacity

Delivery time of steel pipe heating furnace: It will be completed within 45 days after the contract takes effect.
