First, a brief analysis of laser processing technology Laser cutting machine laser processing technology is a fusion of the light, machine, electricity, material processing and testing and other disciplines of advanced composite manufacturing technology. It plays an irreplaceable role in the pillar industries of the national economy such as construction machinery, energy, transportation, iron and steel metallurgy, shipbuilding and automobile manufacturing, electronic and electrical industries, and aerospace.
During the laser cutting process, the laser beam is focused into a very small spot with a minimum diameter of less than 0.1 mm, so that a very high power density at the focal point can exceed 106 W/cm2. At this time, the input of the beam (converted by light energy) far exceeds the amount of heat reflected, conducted, or diffused by the material. The material is quickly heated to the vaporization humidity and evaporated to form a hole. With the relative linear movement of the beam and the material, the holes are continuously formed into narrow slits (eg, about 0.1 mm). The thermal effect of trimming is very small and there is basically no deformation of the workpiece. An auxiliary gas suitable for the material to be cut is also added during the cutting process. When the steel is cut, oxygen is used as an auxiliary gas to generate an exothermic chemical reaction oxidizing material with the molten metal, and at the same time, the slag in the kerf is blown away.
Second, the significant advantages of laser cutting 1: high precision: positioning accuracy of 0.05mm, repeated positioning accuracy of 0.02 mm.
2: Narrow kerf: The laser beam is focused to a very small spot, so that the power density at the focal point is very high. The material is quickly heated to the degree of vaporization and evaporates to form a hole. With the relatively linear movement of the light beam and the material, the holes are continuously formed into narrow slits. The incision width is generally 0.10 to 0.20 mm.
3: smooth cutting surface: cutting surface without burrs, incision surface roughness is generally controlled within Ra is 6.3 ~ 12.5μm or less.
4: speed: cutting speed up to 10m/min, maximum positioning speed up to 70m/min, much faster than the line cutting speed.
5: The cutting quality is good: no contact cutting, the heat affected by the trimming is very small, there is basically no heat deformation of the workpiece, and the collapsed edge formed when the material is punched and cut is completely avoided, and the secondary slit machining is generally not required.
6: Does not damage the workpiece: The laser cutting head does not come in contact with the material surface, ensuring that it does not scratch the workpiece.
7: Not affected by the hardness of the material to be cut: The laser can process steel plates, stainless steel, aluminum alloy plates, hard alloys, etc. No matter what kind of hardness, it can be cut without distortion.
8: Not affected by the shape of the workpiece: The laser processing is flexible and can process arbitrary graphics, and can cut pipes and other profiles.
9: Saving materials: Using computer programming, different shapes of products can be used to set the entire board material to maximize the utilization of materials.
10: Improve the speed of new product development: After the product drawing is formed, laser processing can be carried out immediately to get the new product in the shortest time.
Third, laser cutting is applied to steel and metal materials commonly used in the iron and steel metallurgy industry, including carbon steel, stainless steel, alloy steel, aluminum and aluminum alloys, titanium and titanium alloys, and most nickel alloys, etc., can be laser-cut.
For iron and steel metallurgy companies, the introduction of laser cutting machines has unique advantages for the development of enterprises. First of all, the self-produced sheet is large in scale and complete in variety. The whole production process saves a great deal of auxiliary time and costs. Secondly, as a national key plate production and sales base, it has established extensive sales channels, customer relationships and sales networks for many years. For users with small batch and multi-species demand, laser finished products can be directly provided, the service chain of products can be extended, and secondary benefits can be generated; cutting waste can be quickly recycled and reused; at the same time, intermediate transportation links are reduced. Save costs and maximize profits.
Therefore, laser cutting is suitable for the establishment of a “plate distribution center†in the steel industry, providing products that are free from subsequent cutting and processing according to the needs of users (users), and makes computer discharges to achieve arbitrary cutting in two or three dimensions to maximize savings. Materials and consumables to achieve a win-win situation for steel mills and customers.
It is understood that the Walc series of large-format CNC laser cutting machines produced by Wuhan Faolilai Company can meet the different needs of iron and steel metallurgy companies. The series of models are organized by the experts of the Chinese Academy of Engineering and Chinese Academy of Sciences, Gu Guoxuan, led by an expert group to organize scientific and technological achievements. China's first initiative filled the domestic gap and its main technical performance has reached the international advanced level. The equipment adopts a double-gantry door with a large cross-sectional area and a double-stand steel structure frame crossbeam. It is equipped with a laser-moving, single-side linear guide and a single-side rack and pinion, bilateral synchronous drive, full-flying light path, and other optical path structures. Linkage, 6 motor drives. The working table is 6-30m long and 3-4.5m wide. It can be processed and loaded and unloaded on one side without affecting the cutting process efficiency. The beam path is equipped with a synchronous optical path system to ensure that the laser cutting head can be moved to any position and that it has the same cutting quality.
While the country is vigorously accelerating the implementation of the revitalization plan for the steel industry, laser cutting machines will certainly exert their unique advantages and become a powerful weapon for the steel industry to increase its overall competitiveness.
