2. Bundle weight: not more than 3.5MT for bulk vessel; less than 3 MT for container load

3. Marks:

Color marking: There will be color marking on both end of the bundle for the cargo delivered by bulk vessel. That makes it easily to distinguish at the destination port.

Tag mark: there will be tag mark tied up on the bundles. The information usually including supplier logo and name, product name, made in China, shipping marks and other information request by the customer.

If loading by container the marking is not needed, but we will prepare it as customer request.

Function Structure

Light H-beam has been widely applied as building material and has a very good market prospect. High frequency H-beam welding is a new technology for H-beam welding with the advantages of energy-saving, high efficiency and convenient operation etc.

H-beam welding equipment adopts two sets 300kW or 600kW solid state high frequency welder with exactly the same model. One welds web plate and upper flange plate, the other welds web plate and lower flange plate. The welding mode is contact welding. Solid state high frequency welder adopts AC-DC-AC frequency conversion structure. The rectifier adopts 3-phase thyristor. The inverter adopts high voltage large power MOSFET to form full bridge resonance inversion. Inverter output adopts high efficiency ferrite matching transformer to finish power combination, impedance matching and electrical isolation. Resonance tank circuit adopts two sides serial resonance.

The complete unit of equipment is composed of switchgear rectifying cabinet, inverter output cabinet, contact head mechanism, circulation soft water cooling system, console and 3-D positioning table.

Technical Features

      Ø Perfect structure design

1.Independent design of switchgear rectifying cabinet and inverter output cabinet, connected by soft cable, which is convenient for layout at users site.

2.Power combination of the inverter bridge is accomplished by the way of power unit superposition. Each MOSFET power unit is designed to be 100kW and slideway drawer structure, which is convenient for installation and repair.

3.3-D positioning table is adopted for both of the two sets contact type welder. Contact head adopts pressure control, which has a good synchronism and consistency.

4.High standard electromagnetism compatibility design, electromagnetism radiation meets national standard.

5.Closed cabinet design, meeting rigor environmental requirements on site.


Ø Full-digital Synchronization Control System

1. 3-phase rectifier adopts high cost performance MCU controlling to realize precise synchronism trigger with high control precision and small grid-side non characteristic harmonic.

2. Resonant inverter adopts CPLD to form full-digital control system that is characterized by their automatic constant angle, high phase-lock precise and wide scope of phase-lock.

3. The two sets solid state high frequency welder has the function of synchronization control with the features of stable working and small interference.

4.The welder has perfect protection function with reliable working and low failure rate.


Ø HMI and fault diagnosis system

1. Adopt PLC and touch screen to form perfect HMI system.

2. Realize integrated automatic control of welder system.

3. Fault display and diagnosis system.

Q:H Steel 30, one, 15, how much is 1 tons?
I-beam, channel and angle steel are widely used in industrial buildings and metal structures, such as factories, bridges, ships, agricultural machinery, vehicle manufacturing, transmission towers, transport machinery, often in conjunction with the use of. Flat steel is used as a bridge, a housing, a fence, a transmission ship, a vehicle, etc. on a construction site. Round steel and square steel are used for all kinds of machine parts, agricultural machinery parts, tools and so on.
Q:Specification for splicing length specification of H steel in steel structures
The width of the splice shall not be less than 300mm and shall not be less than 600mm"
Q:What is the length of the butt joint of H steel? What is the minimum requirement?
If the H type steel welding, to avoid flange and web seam in the same section, upper and lower flange splicing and splicing of webs staggered position should be more than 200 mm, flange splicing length should not be less than 2 times the width of the plate (this confused with steel butt not), web splicing width of not less than 300 mm. The length of not less than 600 mm.
Q:What are the main parts of hot-rolled H steel? What kind of project is required to use H steel, and what kind of customer base is best to find when selling H steel?
The use of H steel in industrial and civil buildings not only saves labor, reduces costs, but also reduces the amount of steel used. For example, the steel structure of the mill is reduced by 15%-20% by comparing the amount of steel used between hot-rolled I-beam and hot-rolled wide flange H steel.
Q:How can the steel posts of different types of H steel be butted?
The welded joint, flange should be used in single V groove plate with full penetration weld, the web should use the K shaped groove double partial penetration weld, the opposite is not clear; the design requirements of Web full penetration, such as the web thickness is less than 20mm, should adopt single V groove welding (plus plate figure 4.6.2-1 E), such as the web thickness is greater than 20mm, should adopt the K groove, double negative root cleaning after welding
Q:How to control the welding deformation made of H steel
Features are as follows: wide flange and large lateral rigidity. Good bending resistance. The two surfaces of the flange are parallel to each other, so that the connection, processing and installation are simple. Compared with the welding drawing I-beam, the utility model has the advantages of low cost, high precision, little residual stress, no expensive welding materials and welding seam detection, and the cost of steel structure production is saved by about 30%. Under the same section load, the H steel structure of hot rolled 15%-20% steel is less than that of traditional steel structure. Compared with the concrete structure, the hot rolled H steel structure can increase the use area of 6%, while the structural weight is reduced by 20% and 30%, and the internal force of the structural design is reduced. The H steel can be processed into T steel, and the castellated beams can form various section forms to meet the demands of engineering design and manufacture. H steel is mainly used in engineering, plant, equipment, machinery and equipment, bridges, highways, houses, etc., with good mechanical and physical properties, firm and energy-saving and environmental protection. H steel is a kind of economical type section steel, widely used in industry, buildings, bridges, oil drilling platforms, according to the forecast in 2005 China's H steel demand of about 2 million 500 thousand tons, 5 million tons of demand in 2010, but the H steel of China's annual production capacity of 1 million 200 thousand tons, the market demand is very great.
Q:What are the materials of H steel?
The main material of H steel is Q235B, Q345B and so on.
Q:In the steel structure, the semifinished product H steel column, whether also sets the manufacture quota?
To fully grasp the list items and under the quota sub objective may not converge (including engineering calculation rules, etc.). The quota has the rule of calculation, the list has the rule of calculation, both must be consistent. For example, someone mentioned several times in front of the pipe support and wall bushing, the list should be calculated, but the indoor pipeline installation quota usually include a bracket and a casing (around by), then calculate the duplicate.
Q:What is the height of the four fillet welds in H steel submerged arc welding, such as H600*300*6*12?
The plate thickness is 6 and 12 respectively, and the fillet weld value is the same as the thickness of the thin plate (when the design does not require)
Q:H how long is the length of the steel section?
Hot rolled H steel is usually fixed length of 12 meters or less, if it is welded H steel can reach 20 meters or longer, hot-rolled H steel is too long, transportation is not convenient
