Description
Technical field
The present invention relates to a kind of roll shaft casting mould and its manufacturing process, more particularly to a kind of adjustable roll shaft casting
Mould and manufacturing process.
Background technology
Roll shaft type parts are widely used in the fields such as metallurgy, mine, electric power, petrochemical industry, building materials, machinery, are calendering deformations, broken
Large easily consumption critical component of the equipment such as broken, grinding and supporting, conveying, guiding, consumes more than 500 ten thousand tons year, value more than 1,000 hundred million
Member.Axial workpiece is the critical component of equipment support and passing power, and use is large in number and widely distributed, several hundred billion yuan of year consumption value.Such as
No matter this big learies is all one huge from the production cost of enterprise, or in terms of the energy and resource consumption in China
Big waste, exerts heavy pressures on to environment and resource.Therefore, improve roller component quality and service life China is implemented to save
Energy emission reduction, resource and energy resource consumption are reduced, reduced environmental pollution, promote Circular Economy Development Strategy to have great importance！
Roll is the mother of steel, and no roll is how become a useful person.Roll is the instrument of rolling metal deformation, is on steel rolling equipment
Strength member, during work using a pair or one group of roll roll caused by pressure roll stone roller steel, it is primarily subjected to roll
When Dynamic And Static Loads, abrasion and rapid heat cycle temperature change influence, therefore rolling industry require roll should have high intensity, height
Toughness, high rigidity, high-wearing feature and high thermal fatigue resistance and anti-stick rigidity.Roll directly determines as the critical component of milling train
The reasonability of production technology and the economy of product, its quality is not only related to steel rolling cost and milling train production operational availability, also
Largely influence mill bar quality.
Grinding equipment is widely used in cement, electric power, metallurgy, chemical industry, mine, steel, thermoelectricity, coal and nonmetallic ore etc.
Industry, annual over thousands of kind of material of grinding, such as quartz, gypsum, urea, ferroalloy, coal, slag, ceramics, glass, grinding amount
More than 1000 hundred million tons, and grinding roller is the critical component and key wear part of milling equipment, the quality of its quality, it is particularly resistance to
Mill performance directly influences operating rate, silty amount processed, grinding roller consumption and the production cost of powder processed.China's year consumes various mills at present
More than 100 ten thousand tons of roller, all kinds grinding roller market is more than 15,000,000,000 yuan.
The foundry engieering of large-scale monoblock cast roll and grinding roller, box moulding when recent decades come by producing earliest,
Highly place dark chill along the body of roll to be cast, to the production hollow steel rollses period of the day from 11 p.m. to 1 a.m entirety cold mould hanging sand of today, cold mould hanging sand thickness
Control is in 20~40mm.The thickness of cold mould hanging sand can influence the thermal conductivity of molding sand and coating, and after directly affecting pouring molten steel
Setting rate, the thermograde and Segregation of Chemical Composition of radial direction, to roll barrel surface dense layer column crystal thickness effect very
Greatly, the thinner roll barrel surface dense layer column crystal of cold mould hanging sand is thicker, and Segregation of Chemical Composition is smaller, and work roll cooling performance is got over
It is good, and when producing Integral alloy grain roll, then manufactured using metal cold mould casting technique, then used when producing composite roll from
Heart casting technique manufactures.The various roller class products such as sand casting roll or grinding roller are replaced using metal mold, are on foundry engieering
One much progress.Permanent mold casting roll technology is that the molten iron that will have been smelted is poured into preprepared casting mold, is given free rein to cold
But to after normal temperature, the demoulding is taken out product and is machined out, and is characterized in producing the steady quality of casting, dimensional accuracy higher（One
As be CT7-9 levels）, casting allowance it is smaller, can than sand casting save 15%~30% liquid metal consumption.But
It is that permanent mold casting is because cooling velocity is slow, in eutectoid reaction, austenite is all transformed into coarse pearlity, mechanics
Degraded performance, in order to improve mechanical property, it has to add the alloys such as expensive nickel, chromium, molybdenum adjustment chemical composition, cause
Cost is high.And its metal casting section bar matter is mostly the metal materials such as gray cast iron, spheroidal graphite cast-iron, vermicular cast iron, cast steel, heat resisting steel
Material.At work, metal mold repeatedly bears the impact of high temperature iron liquid repeatedly, is often destroyed because heat fatigue produces cracking, the life-span is relatively low.
Indivedual producers are using forged steel as roll metal mold material, although service life is higher than gray iron casting, manufacturing cost greatly increases
Add, and forged steel cold mould long-term use is easily deformed.Because metal mold works under bad working environments, the limitation of material in itself in addition,
Cause its service life short, normally only just scrapped at 30~50 times because of surface checking, and metal mold manufacture needs large-scale boring
The processing of the equipment such as bed, cost is high, cycle length, so as to have impact on production and economic benefit.
Roll is the primary deformable instrument of milling train, the problem of due to roll itself material and its residing harsh ring
Border, roll is caused often to fail or even scrap.Such as：Roll crosses quick-wearing, surface roughening (orange peel shape), lattice hole, Le
Trace, crack and flake off.But it is summed up, not the problem of outer three aspects：First, the height of wearability (including resistance to roughening)
It is low, second, having the depth of rigidity layer, third, the size of anti-crack ability (including resistance to flaking).Therefore, in order to improve roll
Service life, first roll must have the suitable material of higher abrasion resistance, secondly the hardness of roller surface is hard, and have
There is deeper hardness layer depth, and roll end hardness drop is small（It is preferably controlled in ＜ 2HSD）, thirdly roller surface is again necessary
With high thermal fatigue resistance and cracking.However, the roll produced with prior art is difficult to meet above-mentioned requirements.Cause
This, it is necessary to existing roll material and manufacturing process are improved.
With the horizontal raising of rolling industryization, roll and grinding roller and various roller base part product qualities how are improved, is carried
High metal cold mould die quality, metal cold mould number of molds is reduced, it is that the protrusion faced at present is asked to reduce equipment and production cost
Topic.And it is that fixed nonadjustable metal is cold that traditional roll, grinding roller and various roller base parts is used in Foundry Production
Pattern has, and due to the limitation of its structure, on the one hand causes the odjective causes such as small, the roller solidification cycle length of cooling velocity, causes
As-cast structure inevitably exist it is serious be segregated, the aggregation of loose and association field trash the defects of；Simultaneously because its metal is cold
Type die size is non-adjustable, makes the mould of its every kind of size can only manufacture a kind of product of specification, causes cold mould mould to fill
Divide and utilize, vacancy rate is high, and the roller of plurality of specifications undoubtedly increases the input of cold mould mould, is added significantly to be produced into
This, is unfavorable for saving the energy, improves utilization rate of equipment and installations.Therefore, Novel roller base part cast shaping process and shaping are researched and developed
Mould, to improving roller product quality, cold mould die life is improved, reduces metal cold mould number of molds, improves utilization rate of equipment and installations,
Production cost is reduced, strengthens market competitiveness of enterprises, it has also become the task of top priority of roller base part manufacturing enterprise.
The content of the invention
