Description
Technical field
The present invention relates to wear-resistant material production technical fields, and in particular to a kind of Super-high Manganese cast steel liner plate and its preparation side
Method.
Background technique
Ball mill is the key equipment that material is broken and then is crushed.This seed type ore mill is in its cylinder
It is interior to be packed into a certain number of steel balls as abrasive media.It is widely used in cement, silicate product, New Building Materials, resistance to
The production industries such as fiery material, chemical fertilizer, black and non-ferrous metal ore and glass ceramics, to various ores and other grindability materials
Carry out dry type or wet type grinding.Liner plate be ball mill be used to protect cylinder, make cylinder from abrasive body and material directly impact with
Friction, while various forms of liner plates can also be used to adjust the motion state of abrasive body, to enhance abrasive body to the powder of material
Broken effect helps to improve the mill efficiency of grinding machine, increases yield, reduces metal consumption.The abrasion of liner plate honor is replacement quantity
And the maximum spare part of consumption, in the consuming of assaulting fortified position being easily damaged, consumption is up to 60%.According to different duty requirements,
Liner plate can be used different material manufactures, most of mine, dressing plant grinding machinery generally use potassium steel (ZGMn13) work
For wear-resistant liner material.
Potassium steel refers to steel alloy of the manganese content 10% or more.Potassium steel according to the difference of its purposes can be divided into abrasion-resistant stee and
Nonmagnetic steel two major classes, wherein abrasion-resistant stee dosage is more, be commonly used to the production teeth of excavator, cone crusher roll face the wall and meditate and
Crushing wall, jaw crusher trouble plate, ball grinding machine lining board, railway frog, bar, tup etc..The as-cast structure of potassium steel is usually
It is made of austenite, carbide and pearlite, also contains a small amount of iron phosphide eutectic sometimes.When carbide quantity is more, often in crystal boundary
Upper is in netted appearance.Therefore the potassium steel of as-cast structure is very crisp, is not available, usually used heat treatment method is at solid solution
Steel is heated to 1050-1100 DEG C by reason, as-cast structure is eliminated in heat preservation, is obtained single phase austenite tissue, then water quenching, is made this
Kind tissue remains to room temperature.The intensity, plasticity and toughness of steel increase substantially after heat treatment.The board of Chinese common potassium steel
Number and its scope of application be: ZGMn13-1 (C1.10-1.50) is used for low impulse member, and ZGMn13-2 (C1.00-1.40%) is used for
Common part, ZGMn13-3 (C0.90-1.30%) are used for Complex Parts, and ZGMn13-4 (C0.90-1.20%) is used for HI high impact part.With
The manganese content of upper 4 kinds of trade mark steel is 11.0-14.0%.
Due to the rapid development of modern industry, common potassium steel is either in production technology or performance is all got over using upper
It is more difficult to meet requirement of the present industrial development to equipment, causes a large amount of components report because of abrasive wear in process of production
It is useless to have seriously affected production and economic benefit, how to improve potassium steel and makes it have good wearability and impact resistance
Property, it can reach the wear resistence of large scale equipment, can be used under thump, heavily stressed operating condition, be asking for urgent need to resolve
Topic.
