Description
Technical field
The present invention relates to cement manufacture field more particularly to a kind of cement ball mill wear-resistant liner and its manufacturing methods.
Background technology
Ball mill is the common milling equipment of the industries such as metallurgical ore grinding, cement, power generation.The main function of ball grinding machine lining board is
Protection grinding machine and drive abrading-ball are ground and crush to material.The main failure forms of ball grinding machine lining board are that small energy repeatedly rushes
Abrasive wear under hitting, according to statistics, the steel that China consumes on ball mill every year reach millions of tons.Therefore how ball milling is improved
The wearability of machine liner plate is always the hot spot studied.
It is high strength steel, but its wearability is still poor now to commonly use lining material, and service life is short, since high strength steel is general
Poor toughness, liner plate in use easily occur cracking, collapse it is broken so that repair demolition is extremely difficult；And use low-carbon alloy steel
Manufacture ball grinding machine lining board, and there are intensity and hardness is low, the deficiency that wears no resistance；In order to improve the obdurability of steel alloy and wear-resisting
Property, the alloying elements such as molybdenum, nickel, chromium, tungsten, vanadium will be usually added in, with increasingly in short supply, molybdenum, nickel, chromium, tungsten, the vanadium of alloy resource
Alloys supply is waited to be becoming tight day, price rapidly goes up, and causes common steel wear-resistant material production cost constantly soaring；Meanwhile mesh
Preceding mainstream liner plate is mostly martensite steel sections, is easily undergone phase transition at 250 DEG C or more, leads to liner plate hydraulic performance decline, therefore be not suitable for
For a long time, it works under the operating mode of high intensity.In addition, existing more of liner plate considers intensity, toughness and the corrosion resistance of liner plate in itself etc.,
The ability of liner plate secondary process material is not accounted for, and material is easily adhered on liner plate；Meanwhile stainless steel it is of high cost and intolerant to
Mill, high strength steel is wear-resisting but not corrosion-resistant, easily due to abrasion or corrosion impact working face, while reduces the pure of made material
Degree.
In the related patents applied at home, patent《A kind of large-size ball mill liner plate and its casting method》（Application
Number：201010294909.4 publication date：2011-01-26）, it is excellent to disclose a kind of wear-resisting property, and hardness is high, good toughness, by force
The preparation method of high liner plate is spent, a variety of alloying elements such as silicon, chromium, molybdenum, boron, niobium are added into conventional steel liner plate and promote liner plate
Wearability and toughness, but the liner plate is not corrosion-resistant；In addition, be still martensite steel sections, non-refractory；Simultaneously as matrix limits
System, impact resistance is still poor, and work long hours cracky.Patent《A kind of lining sheet for ball mill of high-wear resistance》（Shen
Please number：201410364512.6 publication date：2014-10-29）, disclose a kind of lining of essential high-strength stainless steel as base material
Plate, and the average tempering technique used, high temperature resistant, but its it is a large amount of employ the alloying elements such as chromium, titanium, raw material smelt it is difficult and
It is poor to simultaneously result in the liner plate Castability for costliness, it is impossible to be used in the large-scale liner plate of manufacture, application range is not wide, at the same time, greatly
The addition of amount carbon also make the liner plate can not complete austenitizing, corrosion resistance is bad.In addition, above-mentioned two parts of patents only consider liner plate
Itself intensity, toughness and corrosion resistance etc. do not account for the ability of liner plate secondary process material, and material is easily adhered to liner plate
On.
