At present, most of the machine tool castings are gray cast iron. The quality of large gray cast iron castings should be controlled strictly from the aspects of chemical composition, raw material quality, ingredients, alloying, melting temperature, incubation treatment and thermal aging. At present, most of the machine tool castings are gray cast iron. The quality of large gray cast iron castings should be controlled strictly from the aspects of chemical composition, raw material quality, ingredients, alloying, melting temperature, incubation treatment and thermal aging. 1, melting links 1) Carbon equivalent. Higher carbon equivalent should be used, HT250, 3.95 is better; HT300, 3.82 is better; HT350, 3.76 is better. 2) Silicon-carbon ratio. Proposed best silicon-carbon ratio control in the 0.55-0.62. 3) alloying control. Addition of alloying elements is beneficial to the improvement of casting performance, generally 0.4-0.6% of w (Cu) or 0.2-0.4% of w (Cr). 2, ingredients Pig iron to join the amount of less than 10%, while using high-scrap, high-carburizing process, so good quality graphite. 3, hot metal temperature High iron liquid temperature can be refined graphite, is a high carbon equivalent, high strength gray cast iron foundation. Iron liquid temperature is 1500-1550 ℃, the oxidation of molten iron will be reduced, SiO2 ash significantly reduced. 4, pregnant Features: Plasma Cutter Sheet Metal Machine,Cnc Plasma Cutting Machines,Fast Speed Plasma Cutter Sheet Metal,Cnc Plasma Cutting Machine HEBEI SENUF MANUFACTURE AND TRADE CO., LTD , https://www.senufmetals.com
1).The beam uses light structural design, with good rigidity structure, light deadweight and small movement inertia.
2). The gantry structure, Y axis used dual-motor dual-driven system, X, Y, Z axis all use dual-straight rail that make the machine driving smoothly with high-precision.
3). Aiming at cutting three dimension LED character, trough metal panels and floor cutting, the accuracy can reach good indicators. Equipped with other advertise equipment (blister machine, engraving machine), forming the advertising word processing pipeline. Completely solve the traditional manual processing methods. Improve the efficiency of several times.
4). Cutting mouth is small, tidy, and avoid a second dressing processing.
5). It can apply to iron sheet the aluminum sheet, the galvanized sheet, hundred steel plates, metal plates and so on.
6). High cutting speed, high precision, and low cost.
7). The numerical control system disposes high, the automatic striking arc, the performance is stable.
8). Support ARTCAM software, Type3 produce standard G code way document, also can change software to read AUTOCAD software produce DXF form documents.
