Description
Technical field
The utility model relates to a kind of Novel roller axle casting and causes mould.
Background technology
Roll shaft type parts is widely used in the fields such as metallurgy, mine, electric power, petrochemical industry, building materials, machinery, and be the large easy consumption critical component of the equipments such as calendering distortion, fragmentation, grinding and supporting, conveying, guiding, year consumes more than 500 ten thousand tons, is worth more than 1,000 hundred million yuan.Axial workpiece is device support and the critical component transmitting power, uses large in number and widely distributed, consumes in year and is worth several hundred billion yuan.So large learies no matter from the production cost of enterprise, or is all a huge waste from the viewpoint of the energy of China and resource consumption, exerts heavy pressures on to environment and resources.Therefore, raising roll shaft part quality and service life implement energy-saving and emission-reduction to China, reduce resource and energy resource consumption, reduce environmental pollution, promote that Circular Economy Development Strategy has great importance!
Roll is the mother of steel, does not have roll how to become a useful person.Roll is the instrument of rolling metal distortion, it is the strength member on steel rolling equipment, utilize during work a pair or one group of roll rolls time the pressure that produces to roll stone roller steel, Dynamic And Static Loads when it mainly bears rolling, the impact of wearing and tearing and rapid heat cycle variations in temperature, therefore steel rolling industrial requirements roll should have high strength, high tenacity, high rigidity, high-wearing feature and high thermal fatigue resistance and anti-stick rigidity.Roll directly decides the reasonability of production technology and the economy of product as the critical component of milling train, and its quality is not only related to steel rolling cost and milling train production operational availability, also affects mill bar quality to a great extent.
Grinding equipment is widely used in the industries such as cement, electric power, metallurgy, chemical industry, mine, iron and steel, thermoelectricity, coal and nonmetallic ore, annual grinding over thousands of kind of material, as quartz, gypsum, urea, ferroalloy, coal, slag, pottery, glass etc., grinding amount more than 1,000 hundred million tons, and grinding roller be milling equipment critical component and key wear part, the quality of its quality, particularly anti-wear performance directly have influence on the operating rate of powder process, powder process quality, grinding roller consumption and production cost.Current China consumes various grinding roller more than 100 ten thousand tons year, and all kinds grinding roller market is more than 15,000,000,000 yuan.
The foundry engieering of large-scale integral casting roll and grinding roller, in recent decades by box moulding when producing the earliest, cast placing dark chill along body of roll height, the overall cold mould hanging sand of the production hollow steel rolls period of the day from 11 p.m. to 1 a.m to today, cold mould hanging sand THICKNESS CONTROL is at 20 ~ 40mm.The thickness of cold mould hanging sand can affect the thermal conductivity of molding sand and coating, and the setting rate directly affected after pouring molten steel, radial thermograde and Segregation of Chemical Composition, breaker roll body surface compacted zone column crystal thickness effect is very large, cold mould hanging sand thinner roll barrel surface compact layer column crystal is thicker, Segregation of Chemical Composition is less, work roll cooling performance is better, and when producing Integral alloy grain roll, then adopt the manufacture of metal cold mould casting process, when producing composite roll, then adopt centrifugal casting technique manufacture.Adopting metal mold to replace the various roller series products such as sand casting roll or grinding roller, is the much progress on foundry engieering.Permanent mold casting roll technology is watered by the molten iron smelted in preprepared casting mold, after giving free rein to be cooled to normal temperature, the demoulding is taken out product and is carried out machined, be characterized in producing the steady quality of foundry goods, dimensional accuracy higher (being generally CT7-9 level), casting allowance less, can save than sand casting 15% ~ 30% liquid metal consumption.But, permanent mold casting due to cooling velocity slow, when eutectoid reaction, austenite is all transformed into coarse pearlity, and mechanical property is low, in order to improve mechanical property, have to add the alloy adjustment chemical compositions such as expensive nickel, chromium, molybdenum, cause cost high.And its metal casting section bar matter is mostly the metal materials such as casting pig, spheroidal graphite cast-iron, vermicular cast iron, cast steel, heat resisting steel.At work, metal mold is repeatedly repeatedly born high temperature iron liquid and is impacted, and often destroy because heat fatigue produces be full of cracks, the life-span is lower.Indivedual producer adopts forged steel as roll metal mold material, although service life is higher than gray iron casting, manufacturing cost greatly increases, and forged steel cold mould Long-Time Service is easily out of shape.Because metal mold works under bad working environments, the restriction of material itself in addition, causes its service life short, generally only just scrap because of surface checking at 30 ~ 50 times, and metal mold manufacture needs the equipment processing such as large-scale borer, cost is high, cycle is long, thus have impact on production and economic benefit.
Roll is the primary deformable instrument of milling train, due to problem and the residing harsh environments thereof of roll self material, causes roll often to occur to lose efficacy and even scrapped.As: the quick-wearing excessively of roll, surface roughening (orange peel shape), lattice are cheated, strangle trace, are ftractureed and peel off.But be summed up, the problem of outer three aspects: one is the height of wearability (comprising resistance to roughening), and two is the depths having rigidity layer, three is the sizes of anti-crack ability (comprising resistance to flaking).Therefore, in order to improve the service life of roll, first roll must have the suitable material compared with high-wearing feature, the hardness of its two roller surface wants hard, and the darker rigidity layer degree of depth will be had, and roll end hardness drop little (preferably controlling at < 2HSD), its three roller surface must have again high thermal fatigue resistance and cracking.But, be difficult to meet above-mentioned requirements with the roll that prior art produces.Therefore, be necessary to improve existing roll material and manufacturing process.
Along with the raising of steel rolling industrialized level, how to improve roll and grinding roller and various roller base part product quality, improve metal cold mould quality, reduce metal cold mould quantity, reduction equipment and production cost are the outstanding problems faced at present.And traditional roll, grinding roller and various roller base part use when Foundry Production is all fixing nonadjustable metal cold moulds, due to the limitation of its structure, cause on the one hand the odjective causes such as cooling velocity is little, roller solidification cycle is long, cause as-cast structure inevitably to there is the defect such as field trash gathering of serious segregation, loose and association; Simultaneously because its metal cold mould size is non-adjustable, make its mould of often planting size can only manufacture a kind of product of specification, cold mould mould is caused not make full use of, vacancy rate is high, and the roller of plurality of specifications increases the input of cold mould mould undoubtedly, significantly add production cost, be unfavorable for economize energy, improve utilization rate of equipment and installations.Therefore, research and development Novel roller base part cast shaping process and mould, to raising roller product quality, improve cold mould die life, reduce metal cold mould quantity, improve utilization rate of equipment and installations, reduce production cost, strengthen market competitiveness of enterprises, become the task of top priority of roller base part manufacturing enterprise.
