Parameter details
1. CGI Multi-head Straight Flame Cutting Machine
CGI multi-strip cutting machine is a high-efficiency oxyacetylene (or propane) flame cutting equipment. There are 13 sets of cutting torches installed in this machine, of which 12 sets of cutting torches do straight cutting along the longitudinal line and 1 group of transverse straight cutting. High cutting accuracy is the necessary equipment for machinery industry, especially for metal structure factory, shipbuilding industry, lifting and transportation machinery industry.

Main technical parameters of CGI-4000:
Rail gauge: 4000mm rail length: 15000mm
Effective length: 80-3300mm cutting thickness: 6-100mm
Cutting speed: 0-750mm/min (infinite speed control)
Longitudinal cutting: 8 groups (straight line cutting) transverse cutting: 2 groups (straight line cutting)
Cutting accuracy: +0.5mm/1000mm drive mode: unilateral drive/bilateral drive
Cutting gas source: oxygen, acetylene or propane supply voltage: AC/220V/50HZ

2.Z15/Z18 H-beam assembling and erecting machine
H-section steel is assembled by two flanges and one web. The position relationship between web and flange directly affects the qualified rate of H-section steel products. The position of each plate can be located quickly and accurately by H-beam erector, which greatly improves the production efficiency.
The machine is mainly composed of portal frame assembly, tie rod system assembly, hydraulic system assembly, input and output raceway assembly, electronic control system and so on. Two CO2 gas shielded welding machines are also equipped for automatic spot welding.

Web thickness(mm) 6-32 6-32
Wing height(mm) 200-800 200-800
Wing thickness(mm) 6-40 6-40
Length of H-beam(mm) 4000-15000 4000-15000
Standing speed(mm /min) 500-6000

3. MZ gantry welder
The submerged arc welding used in this machine is fillet welding. The appearance quality of the weld seam can reach a high standard. The welding method can be selected as single arc single wire. The welding equipment can be used as welding machine or domestic welding machine. Users can choose according to their own needs. This machine is equipped with two sets of floating arc guide device for welding seam, which forces the welding wire to be paired with or made in China during the welding process. Users can choose according to their own needs. This machine is equipped with two sets of floating arc guide device for welding seam, which forces the welding wire to align with the welding seam or the position you choose during the welding process.
Main parameters:
Suitable workpiece web height: 200-1500mm/200-2500mm
Width of workpiece wing: 200-800mm/200-1000mm

Welding Position: Size of Ship Welding Wire: 3.2-5mm
Main engine power: 9KW (excluding two submerged arc welding machine gas source pressure: 0.4-0.6mpa)

4. JZ-40 H-beam flange straightener
Welding and straightening equipment for H-shaped steel flange straightening machine is mainly driven by 22KW large motor and cycloidal pinwheel reducer. The transmission efficiency is high and the straightening speed is fast. All straightening rollers are made of high quality alloy steel and advanced heat treatment technology, which avoids the defect that the part is prone to crack. In order to ensure the stability of straightening and long service life of the part, the welding and straightening equipment for H-shaped steel flange straightening machine is adopted. All parts of the machine are strengthened. The main machine has a proximity control box for easy operation.
Flange width: 200-800mm flange thickness: 6-40mm Note: The thickness and width should conform to the table below, and the material is Q235A.

B 200~800 350~800 500~800 600~800
Minimum web height: 160 mm (when the height of the web is 160-300 mm and the thickness of the wing is less than 14 mm, the use of corrective auxiliary rollers)
Correction speed: 18 000 mm
Switchboard power: 24.2KW

5. HP1018-8 H-beam shot blasting machine
H-shaped steel series shot blasting cleaner is a kind of passing automatic shot blasting cleaner. It can be used for surface cleaning and strengthening of metal structural parts, H-section steel, steel plate and other profiles. Through shot blasting cleaning, not only the rust on the surface of the workpiece can be removed, the welding slag on the structural parts can be cleared, but also the welding stress can be eliminated, the fatigue strength of the workpiece can be improved, and the adhesion of the paint film can be increased when the workpiece is sprayed, and finally the purpose of improving the whole surface and internal quality can be achieved.
