The spheroidizing agent comprises the following components: 35 to 40 percent of Si, 7 to 10 percent of Mg, 2 to 3 percent of Re, 1 to 2 percent of Ba, 1 to 2 percent of Bi, 1 to 2 percent of Ca, and 1 to 2 percent of Sb.
Description
Technical field
The present invention relates to nodulizing agent, be specifically related to a kind of composition and preparation technology of nodulizing agent.
Background technology
Piston ring is widely used in various power machines, as steamer, steam turbine, diesel engine, petrol motor, compressor, hydropress etc.General piston ring is installed in the annular groove of piston, and it forms the chamber acting with elements such as piston, cylinder sleeve, cylinder caps, and it is in and works under high temperature, high pressure, the high speed condition in oil engine, is vital part on the oil engine.
Piston ring is divided into integral loop, associative ring, compression ring, oil ring, channel oil ring, coil spring loaded slotted oil control ring, steel band compound oil ring.
Integral loop: in an annular groove, only assemble the piston ring that a part is formed;
Associative ring: the piston ring that two or more parts of assembling are formed in an annular groove;
Compression ring: the piston ring that is mainly used to prevent gas leakage;
Oil ring: have oil return hole or equivalent structure, can scrape the oil ring of machine oil from casing wall;
Channel oil ring: parallel sided has two contactless ring banks, and the oil ring of oil return hole is arranged;
Coil spring loaded slotted oil control ring: in channel oil ring, add and put the helical supporting spring oil ring.Support spring can improve radially specific pressure, to the ring body internal surface in the reactive force equalization;
Steel band compound oil ring: by support spring and two oil rings that loop combines.
Ring is in oil engine, except that bearing the abominable working conditions of high temperature, high pressure, also will do high speed motion, the distance that general middle-size and small-size oil engine ring is per hour passed by will be more than 48000 meters, and therefore ring must have high strength, high abrasion, good oil storage performance.Along with the speed-raising of engine, develop to high-power, supercharging direction, traditional piston ring material has not satisfied the requirement of modern engine.
Summary of the invention
The objective of the invention is to: a kind of composition and preparation technology of nodulizing agent are provided, make piston ring, can satisfy the demand of modern engine with the composition and the preparation technology of nodulizing agent of the present invention.
The technical scheme that technical solution problem of the present invention is adopted is: the composition and the preparation technology that develop a kind of nodulizing agent, after the nodularization of piston ring casting liquid, change its metallographic structure, make graphite form become vermiform, improve the physical strength and the wear resistance of piston ring, reach the requirement of modern engine high-temperature, high pressure and high abrasion.
The component prescription of this nodulizing agent is: Si 35%～40%, and Mg 7%～10%, and Re 2%～3%, and Ba 1%～2%, and Bi 1%～2%, and Ca 1%～2%, and Sb 1%～2%.
Above-mentioned alloying element mixes system, and particle is strict controlled in 5～7 millimeters scopes.
Beneficial effect of the present invention is: the piston ring after the spheroidizing, significantly improve the graphite form of metallographic structure, and make the flaky graphite of wedge angle become vermiform graphite, the end of graphite is the R shape, improves the mechanical property of piston ring material, prolongs piston ring work-ing life.
