Forging materials are mainly components of carbon steel and alloy steel, followed by aluminum, magnesium, copper, titanium and its alloys.Material of the original state has a bar, ingot casting, metal powder and liquid metal.Metal in the deformation of the cross-sectional area before and after defor

From all kinds of impurity is contained in liquid aluminum electrolyzer suck out, so the casting needs to be cleaned before.Industry mainly adopts clarification, flux and gas purification method, also some trial directional solidification purification and filtering methods.1. Flux flux purification

Magnetic separator is suitable for the size 3 mm below the magnetite, pyrrhotite, roasted ore and ilmenite wet magnetic separation of materials, also used in coal, non-metallic mineral, building materials and other materials in addition to iron.Magnetic separator magnetic system, USES the high quali

The use characteristic of high pressure pneumatic ball valve1, fluid resistance small, pneumatic ball valves are classified all valves fluid resistance in the smallest one, even the pneumatic ball valve, reducing the fluid resistance is small.   2, thrust bearings reduce stem friction torque, can ma

(1) welding procedure qualification should be based on reliable steel welding performance, and up until completion of the works.Welding parameters used in the welding procedure qualification, in principle is according to the weldability of the steel welding test result to determine, especially after

In the use of foundry casting or coated sand casting casting process, if the casting operation not skilled, there may appear the phenomenon of adhering sand castings, once appear this kind of circumstance, light person affect the appearance of the casting quality, the most serious casting scrap dire

Measurement of magnetic field intensity meter have tesla meter (previously called gauss meter) and fluxmeter.Tesla meter using the method is simple, high measurement precision, is currently the most widely used instrument measuring magnetic field intensity, so this paper mainly introduces using the

Electromagnetic valve, regulating valve, drive installed what's the point?(1) the electromagnetic valve installation points:Solenoid valves shall be stipulated in the instruction manual before installation check the resistance between the coil and the body, should be simulated test.The calibre of th

In order to avoid cold crack and improve the mechanical properties of welded joint, heat and welding after preheating, high temperature should be taken round the fire.(1) preheating before weldingWelding of martensitic stainless steel, especially in use with parent metal components of welding materi

Forging is one of the forming process of aluminum wheel application earlier.Forging aluminum wheel with high strength, good resistance to corrosion, and the advantages of small size precision, processing capacity, in general, its weight is equivalent to the same size steel wheel only 1/2 or more low
