The present invention relates to steel ball production technical field, specifically a kind of Large-diameter wear-resistant steel ball and production technique thereof.
Background technology
Whole world year, 80% was casting with ball mill wearing steel ball 2,600 ten thousand tons.Because cast ball power consumption is high, production efficiency is low, poor toughness.Can not produce the major diameter steel ball exceeding diameter 120mm to 200mm, current modernization digs up mine ball mill diameter naturally more than 6.8-13 rice.Study a kind of production major diameter forged steel ball proprietary material and tempering process of quenching, the alternative forging of traditional cast ball ball material, Technology, product index, fill the domestic gaps.
Summary of the invention
In order to overcome above-mentioned technical disadvantages, the invention provides a kind of Large-diameter wear-resistant steel ball and production technique thereof, described abrasion-proof steel ball adopts high-carbon low-alloy high-abrasive material, can meet shaping after diameter 120mm to 200mm major diameter steel ball remnant forging thermal quenching and can make steel ball toughness keep fall 10,000 times indeformable, can enhance productivity simultaneously, reduce labour intensity, save production cost.
The technical solution adopted for the present invention to solve the technical problems is,
A kind of Large-diameter wear-resistant steel ball, comprises the material of following weight percent:
C：0.6％-0.7％
Mo：0.95％-1.25％
Ti：0.01％-0.02％
Si：0.25％-0.45％
S: be not more than 0.03%
P: be not more than 0.035%
Cu: be not more than 0.2%
Impurity: be not more than 0.003%
All the other are Fe.
A kind of Large-diameter wear-resistant steel ball production technique comprises the following steps:
1) square steel be made up of above-mentioned abrasion-proof steel ball material or round steel are cut into ball material by certain length for subsequent use, then, put into process furnace homogeneous heating, Heating temperature is to 900 DEG C-1050 DEG C;
2) ball material is put into forging roll, be in 750 DEG C of-900 DEG C of environment in temperature, carry out being forged into steel ball;
3) steel ball is put into WATER AS FLOW MEDIUM to heat-treat, when temperature is 300 DEG C-350 DEG C, steel ball water outlet enters waste heat tempering unit, and slow cooling to 30 DEG C-60 DEG C, namely prepares shaping.
Further, the heat treated temperature of WATER AS FLOW MEDIUM put into by steel ball is 450 DEG C;
Further, steel ball carries out the time of slow cooling is 48 hours;
The beneficial effect that the present invention produces is, 1, ball technical indicator is forged according to international state-of-the-art major diameter (120mm-200mm), in conjunction with domestic existing steel-smelting technology and noble metal mineral resources condition advantage, develop the material exceeding domestic excellent carbon alloy steel, form and lower than 1/5th, the product cost competitive power after utilizing should be increased; 2, by existing roll forging steel ball automatic production line, novel, the efficient major diameter wear-resistant forged steel ball leading with producing domestic and international market after this combine with technique, fills the domestic gaps, and meets the installation of domestic and international large-size ball mill and uses.
