Abstract
A high-strength antiwear ball is made up through smelting the molten low-Mn antiwear steel or molten medium-carbon low-alloy steel, centrifugal or vibration-type casing, and afterheat quenching. It has high hardness (55+/-10 for HRC) and the metallurgical structure of martensite or martensite plus bainite.
Description
Technical field the present invention is a kind of abrasive body---the abrading-ball that materials such as coal-fired thermal power plant, thermo-power station, cement production enterprise, metallurgical mineral products are pulverized usefulness, especially a kind of high strength anti wear ball of being used for.
Background technology is pulverized in the plant equipment of grinding at material, and mill ball or title steel ball are indispensable supporting machinery products, occupy very consequence.There has not been it, material raw coal, ore ... just can't become superfine powder supply station boiler combustion and produce cement products, smelt gold, silver, furnace charge such as copper, iron.The abrading-ball kind of current use has the middle and high evanohm casting ball of urib founding, carbon steel or steel alloy forging steel ball that Cutting stick becomes pipe nipple to heat to forge quenching again.The cast iron product antiwear property is extremely low, impact flexibility is low, percentage of damage is high, high-chromium alloy casting ball abrading-ball per ton will consume 1/2nd low-carbon ferrochromium and other alloy nearly, the steel ball blanking that forge hot is beaten adopts round steel or square steel to cut off, heating forges into steel ball more again, special tooling quenches, and operation is many, cost is high.
Summary of the invention the object of the present invention is to provide a kind of wear resistance ideal, percentage of damage is low, operation is simple, with low cost high strength anti wear ball.
For achieving the above object, the technical scheme that the present invention takes is: this high strength anti wear ball is to smelt qualified antiwear low-manganese steel water or other molten steel by intermediate frequency converter or other converters, directly be poured into the high wear-resistant ball of as cast condition that centrifugal or oscillatory type casting machine is cast as all size of diameter phi 20～120mm, immediate quenching processing hardness HRC reaches 55 ± 10 after 900 ± 100 ℃ of castings, and the metallographic matrix is: martensite or martensite+bainite.
Above-mentioned high strength anti wear ball provided by the invention, be to adopt the high wear-resistant ball of medium carbon low alloy steel water as cast condition centrifugal or the vibrating machine cast molding, change abrading-ball sandbox casting in history, forged the traditional handicraft of moulding, it has wear resistance and reaches best, long service life, percentage of damage is low, turns round characteristics such as effective conservation of power.It is few to grind ton product supplies consumption abrading-ball, and the product cost can reduce about 20% than the existing asuforging steel ball that uses.
Specific embodiment high strength anti wear ball provided by the invention, it is to smelt qualified antiwear low-manganese steel water or other molten steel by intermediate frequency converter or other converters, directly be poured into the circular abrading-ball that centrifugal or oscillatory type casting machine is cast as multiple diameter specifications such as diameter phi 20～120mm, utilizing 900 ± 100 ℃ of waste heats after the casting directly to enter movable water or saline solution quenching-in water handles, reduced the energy that adds heat loss for twice, Rockwell hardness HRC after the quenching reaches 55 ± 10, and the metallographic matrix is: martensite or martensite+bainite.Because be that the high wear-resistant ball metal structure of spun casting is closely knit, can significantly reduce fragmentation, as cast condition can become and realizes that original heating forges the product of the hardness standard of the representative wear resistance that just can reach, directly for user's use of installing.
