Technical field
The utility model relates to the quenching device of steel band, and especially a kind of no hydraulic plate quenching device of steel band continuous quenching is applicable to steel band continuous quenching production line.
Background technology
Spring steel band has higher elasticity and wear resisting property, be widely used in automobile clutch, bricklayer's instrument, rolling screen door spring, footwear with iron plate, spin products such as knitting needle.Spring steel band is generally medium high carbon carbon steel or steel alloy materials such as 50#, 65Mn, T8A, needs just can obtain hardness to cooperate with flexible, thereby have higher elasticity and wear resisting property by quenching, tempered thermal treatment process.
In the production, steel band adopts the continuous quenching cooling apparatus usually, and the steel band under the high temperature austenite state is cooled fast to below the martensite transformation temperature Ms.For this reason, need realize with material with quick cooling power.What generally adopt is the quenchant of liquid, as quenching oil, water-soluble polymer solution, fused low melting point metal liquid etc.Because gas cooling speed is not high enough, only be applicable to the occasion of vacuum and high alloy mould steel; On the other hand, though solid metal has good thermal conduction capability, can only be the contact of multiple spot shape when they contact with high-temperature steel belt, so heat-transfer effect be unsatisfactory, also can abrade steel strip surface simultaneously.Therefore, with the most use in the actual production, quenching oil the most generally.But complicated with oil quenching refrigerative equipment, the more important thing is, when high-temperature steel belt contacts with oil, can produce a large amount of smog, environment is caused severe contamination, influence workers ' health, also easy presence of fire; In addition, the quenching oil price is expensive, the production cost height.And water-soluble polymer solution and molten metal exist stability not high, problem such as difficult in maintenance, environmental protection.Therefore, the wet goods liquid that how can quench is realized steel band cooling fast continuously, becomes the difficult problem of steel band industry.
China's utility model 200320103136.2 discloses " a kind of press quenching device that is used for thin specification armour plate ", it adopts upright pressure type quenching apparatus to utilize certain thickness separation steel plate that the armour plate of water coolant and quenching is isolated, separate in the steel plate and inlay cooling water circulation pipeline, cool off separating steel plate by water coolant, further cool off armour plate by separating steel plate again, reached the purpose that realizes quenching by the solid flash heat transfer.There is following shortcoming in it: (1) adopts the slack quenching mode, and (specification of every steel plate is that 1000mm * 2000mm), production efficiency is lower to steel plate quenching in the embodiment one by one; (2) cooling water circulation pipeline is little with the contact area of separating steel plate, thereby the capacity of heat transmission that causes separating steel plate descends, and makes the speed of steel plate cooling slow, causes steel plate quenching efficient to improve.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of no hydraulic plate quenching device that does not need any liquid quenching medium, non-environmental-pollution, equipment is simple, production efficiency is high, surface smoothness is good steel band continuous quenching.
The technical scheme in the invention for solving the above technical problem is: this no hydraulic plate quenching device comprises upper and lower two water tanks, and each water tank is provided with water-in and water outlet, is provided with some guide water boards in the water tank; Steel band passes through between two water tanks, and each water tank is a pressing plate near a side of steel band, is lined with protecting sheet between pressing plate and the steel band.
Pressing plate described in the utility model and protecting sheet link together.
Protecting sheet described in the utility model adopts heat conductivility excellence, skin friction coefficient material little, that have deformability to make, and can be expanded graphite plate or strengthens expanded graphite plate.
Pressing plate described in the utility model adopts heat conductivility metallic substance good, that have intensity to make, and can be copper, aluminium or iron.
The utility model compared with prior art, have following beneficial effect: (1) is different fully with existing quenching method, need not use any quenchant, utilize heat the high heat conduction solid by closely contact of the principle of solid heat transfer with steel band, by water heat is constantly taken away, reach the purpose of quenching, use this device to quench, production cost is low; (2) do not have environmental pollution, can realize cleaner production; (3) steel band is a continuous quenching, and promptly steel band quenches while moving, and production efficiency is compared with slack quenching, improves a lot; (4) be provided with protecting sheet in the both sides up and down of steel band, protecting sheet plays a protective role simultaneously to steel band and pressing plate, makes steel band and pressing plate be difficult for pulling, steel strip surface can not damaged, improved steel strip surface smooth finish, clamp surface can not damage, and improves the work-ing life of pressing plate; When entering tempering stove after (5) steel band quenches, can not bring any impurity into, help steel band and realize that in tempering stove the surface turns blue, can save product cost in a large number, further enhance productivity; (6) device center platen and water tank link together, be connected with some guide water boards on the pressing plate again, water directly contacts with pressing plate, guide water board, guide water board has also increased the contact area of pressing plate and water greatly except that being used to guide water flows, and makes the heat conductivility increase of pressing plate, and guide water board and pressing plate connect together, also increase the intensity of pressing plate, thereby can reduce the thickness of pressing plate, further increased the heat conductivility of pressing plate.
