Description

For manufacturing for making the grinding roller of vertical roll grinder or the wear-resisting of lining board for grinding discs Wear-resistant composition of ingredient and preparation method thereof
Invention field
The present invention relates to vertical roll grinder.More particularly it relates to vertical roll grinder is wear-resisting Ingredient (wear-resistant components, wear resistant component).The most specifically, the present invention Relate to manufacture the wear-resisting ingredient for the grinding roller or lining board for grinding discs making vertical roll grinder Wear-resistant composition.
Background of invention and prior art
In some industries, the various equipment being referred to as grinding machine are used to crush or grinding-material.Such as, Steam power plant grind coal, in cement plant grinding stone lime stone, coal and grog, and mining industry Before purification various other materials picture gold, zinc, ferrum, they are crushed.
Various grinding machine is employed in these industries.Some examples are horizontal mill, i.e. a kind of The structure of cylinder class, this structure has the abrasion-proof backing block of the housing of protection grinding machine, by each room of grinding machine Separate dividing plate and the abrasive media ball/rod of crushing material.Make grinding machine rotate with critical velocity, pass through Such mode, ball rises to top and falls under the effect of its gravity, and therefore helps to press Broken.
Other examples of grinding machine include ball mill (the Ball and with base ring, apical ring and hollow ball Race mill).Ball rotates on the track of ring, crushes material to be crushed.Take out the material of crushing There are other ancillary equipment and method.
Another type of grinding machine is roller mill.Roller mill be used for reducing block materials (in bulk Material, bulk material) size many industrial departments in stood firm heel.Roller mill also by It is referred to as bowl shaped mill machine or vertical roll grinder.Advantage for the grinding machine of minification is not only their height Treating capacity (throughput rate), and be the relevant granular size of final products and size distribution and High-quality in terms of their energy requirement.Roller mill is generally used for coal-burning power plant and cement plant.At electricity Factory, roller mill is used for grinding coal, and in cement plant, roller mill is for reducing the size of raw material And be used for grinding coal.Recently, for grinding and granular blast-furnace cinder for finished cement The demand of the grinding machine of these types ground increases day by day.It addition, have multiple in other industrial departments Utilize other application some of the advantage that roller mill provides.In vertical roll grinder, except by crushing The ancillary equipment that material takes out, two main wear-resisting ingredients are grinding roller and lining board for grinding discs (table liner).The principle of this roller mill work is that the equipment on the track by being formed by lining board for grinding discs drives Action roller.Material to be crushed falls in orbit, and crushes between roller and lining board for grinding discs.Then, logical Cross other ancillary equipment to be taken out by the material of crushing.
Various grinding roller and lining board for grinding discs is had on market.Discuss some of which herein below:
I. built-up welding grinding roller (weld over lay grinding roll) and lining board for grinding discs:
In built-up welding grinding roller and lining board for grinding discs, by welding procedure at soft hollow steel rolls or the base of lining board for grinding discs Wear-resisting hard solder alloys is deposited at the end.The substrate of grinding roller and lining board for grinding discs generally is passed through to pass by mild steel The casting technique of system is made.The thickness of welding can according to required life-span the most with good grounds various other because of Element and change.
Ii.Hi-Cr (Gao Ge) and the grinding roller of other wear-resisting grades and lining board for grinding discs:
In the roller and lining board for grinding discs of these kinds, complete by wear-resisting and hard high chromium grade casting Grinding roller or complete lining board for grinding discs.But, it is limited in that: not only in the core never ground Place or waste the Hi-Cr of costliness without worn area or do not use in district (non performing area) Material, but also this material must be annealed, in order to the installation (fitment) of processing Hi-Cr material Region.
Iii.Ni hard bimetallic grinding roller:
In the hard Dual-metal roller of Ni, grind (and being consumed) by centrifugal casting technique by helping Outer surface is cast into the hard grade of wear-resisting and hard Ni, and core is by the most less expensive but also more hold Easily processing is castiron.The grinding roller of these kinds is generally hard with traditional Ni and Hi-Cr mill Liner plate is used together.
In above-mentioned grinding roller and lining board for grinding discs, there is no plug-in unit (insert).At some grinding rollers and mill In liner plate, it is provided that plug-in unit is as wear-resisting ingredient.These plug-in units are made up of hard and wear-resisting material.
Past had carried out some and had attempted, by casting plug-in unit the most respectively, then by machinery Plug-in unit is fixed and is manufactured grinding roller and lining board for grinding discs by power, chock, bolt and many additive methods.
Do not use metal insert but also use other plug-in units, if having manufactured the plug-in unit of dry type, The example is metal oxide powder, alumina particle block etc..
Other are attempted also to have carried out some, cast plug-in unit in a different manner, and an example is by making pottery Grain impregnating metal plug-in unit.
A lot of patent is had in high-abrasive material field.Some of which is discussed herein below:

Advantages of the present invention
1, compositions proposed by the invention ensure that the life-span of wear-resisting ingredient improves, and this is not only Save material cost, and helped to save the cost changing wear-resisting ingredient.Additionally, so The time consumed when doing, grinding machine is also inoperable, and therefore, improves wear-resisting ingredient Life-span decreases the downtime of grinding machine/equipment, and improves the productivity of factory.
2, the character of binding agent and the mixed proportion of binding agent and the mixing of granule, manufactures block The method of part is simpler.The method need not any gasification, therefore reduces cost and workload.
3, owing to employing the magnesium oxide of higher amount (quantum), the fire resistance of block part improves.
4, owing to employing the magnesium oxide of higher amount, the method manufacturing wear-resisting ingredient can be at height Reach and carry out under the higher temperature of 1800 DEG C.
5, because titanium oxide has the restriction of cracking, so using small amount of titanium oxide to ensure that joint About cost and avoid cracking.
6, improve the life-span of granule by various coating coated particles, and and then improve block part and The life-span of wear-resisting ingredient.
7, plate is used to ensure that the proper position that block part is maintained in plug-in unit when manufacturing plug-in unit.This It is very important, because wear-resisting ingredient should be on wearing face, and if we are normal Ground casting ingredient, block part is likely to mobile, and block of making pottery is maintained at inside.
8, due to the variable coefficient of thermal expansion/contraction of Hi-Cr metal, block part and plate, heat is used to fall Sand technology decreases the probability of wear-resisting ingredient cracking, and therefore decreases scrappage.Because I Start heat treatment steps from 350 DEG C, and temperature is not being had during room temperature rises to 350 DEG C There is waste energy, so it also a saving the energy carrying out heat treatment step.
Although being described above each embodiment of the present invention it should be appreciated that, this A little embodiments are only used to citing rather than propose to limit.Those skilled in the relevant art It will be appreciated that on the premise of without departing from the spirit and scope of the present invention, can be in the form and details Carry out various change.
