Abstract
The present invention relates to high wear resistant alloy, and the chemical composition comprises 0.4 to 1.5% of C, 6.0 to 20% of Mn, 1.0 to 3.0% Cr, 0.5 to 4.0% Ni, 0.05 to 0.25% of inoculant, Si, S and P, wherein Si content is less than or equal to 0.8, S content is less than or equal to 0.04, and P content is less than or equal to 0.06. A production method for the high wear resistant alloy comprises the steps of casting shaping, electric furnace smelting and casting pouring, and is characterized in that after cooling, temperature control, water explosion, natural cooling and clearing are carried out, finished products of the castings are manufactured by machine processing, and the temperature is controlled from 450 to 949 DEG C. The high wear resistant alloy breaks through a forbidden region that the temperature of austenite wear resistant molten steel toughness can not be lower than 950 DEG C, simplifies the technological process, saves energy, and reduces the environmental pollution. Compared with similar products, the high wear resistant alloy improves the wear resistance performance by 30 to 70%, and can be used for manufacturing lining boards, jaw boards, hammer heads, bucket teeth, concrete delivery line elbows, head blasting blades for shot-blasting machines, etc.
Description
(1) technical field
The present invention relates to a kind of high wear-resistant ally and production method thereof, specifically relate to a kind of casting wear-resistant steel (iron) foundry goods and method of manufacturing technology thereof.
(2) background technology
Casting anti-(resisting) mill steel (iron) foundry goods, is a kind of consumable material that has a large capacity and a wide range, and it is mainly used in mining machinery, road building machine, rail facility, aspects such as conveying machinery.High speed development along with the development of the national economy, demand to wear resistant alloy is increasing, as the jaw, tup, bucket tooth, concrete transfer line elbow, shot-blasting machine of making various abrasion-proof backing blocks, jaw crusher are with ramming head blade or the like, particularly more and more higher to the requirement of its wear resistance, to increase the service life, enhance productivity, reduce production costs.
The wear resisting property of foundry goods, except working condition (unmodifiable factor) importantly according to the operating mode characteristics, determine its selection proportioning and technology.At present be to adopt traditional austenite abrasion-proof steel (British Hadfield substantially, invented this steel grade in 1882, and name), its technological process comprise foundry goods moulding (coremaking)-electrosmelting-cast article-cooling-sand removal-reheat-water tough-cooling cleaning-machining casting finished products, wherein the tough processing of water forbidden to be lower than 950 ℃ the forbidden zone (in, state such as U.S., day all fixes on 1080 ℃, 1050 ℃, 1000 ℃, greater than with equal 950 ℃), this has just seriously limited the raising of foundry goods wear resistance, and the traditional technology cast cleaning can cause very big pollution to environment.
(3) summary of the invention
The technical problem to be solved in the present invention provides the production method of a kind of high wear-resistant ally and high wear-resistant ally.
High wear-resistant ally, its main points are by weight percentage, C content is 0.4-1.5%, contain the Mn amount and be 6.0-20%, contain the Cr amount and be 1.0-3.0%, ni content is 0.5-4.0%, nucleating agent content is 0.05-0.25%, Si content≤0.5, S content≤0.04, P content≤0.06, and surplus is Fe.
Wherein nucleating agent is hybridly prepared into by molybdenum-iron and rare earth, and its proportioning is Fe-Mo: R
E=1: 1.R
ECan select 1 for use
#Rare earth.
The production method of high-wear-resistant alloy is foundry goods moulding (coremaking)-electrosmelting-cast article-thermal treatment.It is characterized in that thermal treatment process is that the cooling temperature control is at 450-949 ℃, it is quick-fried to carry out water, clear up behind the naturally cooling then, mechanical workout is made casting finished products, thereby successfully in 450-949 ℃ temperature section, realized the production of high wear-resistant austenitic alloy foundry goods, broken through the forbidden zone that austenite abrasion-proof molten steel tough processing is not less than 950 ℃.
The present invention is according to the structure and the wear-resisting requirement of foundry goods, innovated the tough treatment process of water, adopt that water is quick-fried to carry out tough processing of water and sand removal, thereby improved the dust work of sand removal operation and significantly improved foundry goods anti-(resisting) mill performance (can improve wear resisting property 30-70%), with building trade concrete transfer pump elbow is example, at operating mode (cement under the harsh conditions extremely, sand, stone), the product made from method of the present invention has improved more than 70% than the Hadfield steel wear resistance with material, be that this wear-resisting alloy steel reaches 14000 cubic metres by the concrete amount, and similar wear resisting steel can only reach 8000 cubic metres, and mechanical workout is difficulty especially, therefore economic benefit of the present invention is fairly obvious, also solved the machining difficult problem of austenite abrasion-proof steel, in case promote the use of in relevant industry, its social benefit is very considerable especially.
