Abstract
The invention discloses a heat treatment process for high-carbon steel wires for wire ropes. In the process, high-carbon steel wires, the diameter of which is 2mm to 5mm, are heated to the temperature of 780 DEG C to 900 DEG C by way of induction heating, resistance furnace heating or electric contact heating, moreover, the heated steel wires are kept under the temperature of 780 DEG C to 900 DEG C for 10 seconds to 2 minutes, then quickly put into a salt bath and kept under constant temperature in salt bath lower than sorbitizing temperature for 1 to 20 seconds, the steel wires are then put into salt bath or lead bath within the sorbitizing temperature range, kept under constant temperature for 20 seconds to 1 minute and then taken out to be naturally cooled, and therefore the high-carbon steel wire-sorbitizing heat treatment process is fulfilled. According to the process, the sorbite group size and interlayer spacing of the steel wires can be effectively refined and the uniformity of interlayer spacing can be improved, and the product has the advantages of high plastic strength, excellent fatigue resistance, long service life and the like. The process plays a significant role in enhancing the plastic strength and fatigue lives of steel wires.
Description
Technical field
The present invention relates to a kind of wireline with high-carbon carbon steel wire thermal treatment process, belong to wireline heat treatment of metal wires technical field.
Background technology
In existing wireline ME, at first need make steel wire and then it is twisted into thigh, synthesize wireline at last.The steel wire of making wireline at present is mainly the high-carbon carbon steel wire; When producing existing these high-carbon carbon steel wires; To thermal treatment process between wherein mainly is to adopt resistance furnace or electrically contact the heating back to get into the isothermal quenching of lead bath groove and accomplish sorbitizing; These technologies are because the direct isothermal in the sorbite district; Make its interlamellar spacing can less than 100nm, group's size all between 3～10mm, can not give full play to the performance potential of sorbite tissue, thereby make the strong plasticity of existing high-carbon carbon steel wire and strain fatigue life-span not ideal.So existing still is not ideal enough to wireline with the effect of the thermal treatment process of high-carbon carbon steel wire.
Summary of the invention
The objective of the invention is: provide that a kind of sorbite organized layer spacing is even, interlamellar spacing is little, intensity plasticity is good, anti-fatigue performance is excellent, the wireline of long service life is with high-carbon carbon steel wire thermal treatment process, to overcome the deficiency of prior art.
The present invention is achieved in that a kind of wireline of the present invention uses high-carbon carbon steel wire thermal treatment process to do; To be 2mm ~ 5mm high-carbon carbon steel wire be heated to temperature through induction heating, resistance furnace heating or the mode that electrically contacts heating with diameter is 780 ℃～900 ℃; And heated steel wire was kept 10 seconds～2 minutes under 780 ℃～900 ℃ temperature; Thereby achieve quick austenitizing; Steel wire after will heating then puts fast in the salt bath that isothermal keeps after 1 second～20 seconds in the salt bath that is lower than the sorbitizing temperature into; Salt bath or the lead bath isothermal of again this steel wire being put into the sorbitizing TR keeps taking out naturally cooling after 20 seconds～1 minute, can accomplish the thermal treatment process to the sorbitizing of this high-carbon carbon steel wire like this.
Above-mentioned when heated steel wire is kept 10 seconds～2 minutes under 780 ℃～900 ℃ temperature, the time that the steel wire that its diameter is big keeps is greater than the little steel wire of diameter.
The above-mentioned sorbitizing temperature that is lower than is 300 ℃～480 ℃.
Above-mentioned sorbitizing TR is 500 ℃～600 ℃.
Owing to adopted technique scheme; The present invention is from the angle of pearlitic transformation motivating force; Adopt the cold isothermal method again of serious offense; So significantly refinement sorbite tissue mass size and interlamellar spacing, thus the intensity plasticity of high-carbon carbon steel wire improved, for a new approach is provided the fatigue lifetime that significantly increases steel cable.The present invention is according to the gauge of wire size, and elder generation behind austenitizing temperature, puts into steel wire heating fast the salt bath that is lower than 480 ℃ and keeps the several seconds to obtain big supercooling degree, and the lead bath isothermal of putting into again more than 500 ℃ is accomplished sorbitizing.Being bigger than the cold sorbite group nucleation rate that can make significantly increases, and the isothermal more than 500 ℃ makes the sorbite group nuclear embryo completion sorbitizing of growing fast, can obtain the sorbite tissue more than 93%, finally accomplishes the thermal treatment of steel wire.Through test, adopt the sorbite organized layer spacing of the steel wire that the present invention handled even, and its interlamellar spacing is generally 20～70nm, its size is less than 2mm.Owing to significantly reduced group's size, this has vital role to plasticity and the toughness that improves steel wire, reduces the interlamellar spacing level of then can gaining in strength.So, the present invention compared with prior art, the present invention can effectively reduce sorbite group size and interlamellar spacing, improves the homogeneity of interlamellar spacing, its product has high, the advantages such as anti-fatigue performance is excellent, long service life of intensity plasticity.The present invention is to the strong plasticity that improves the steel wire wire rod and have remarkable effect fatigue lifetime.
Embodiment
Below in conjunction with embodiment the present invention is done further to say in detail.
Embodiments of the invention: at a kind of wireline of embodiment of the present invention during with high-carbon carbon steel wire thermal treatment process; Its used high-carbon carbon steel wire is the high-carbon carbon steel wire that is usually used in making wireline in the prior art; During enforcement; To be 2mm～5mm high-carbon carbon steel wire be heated to temperature through traditional induction heating, resistance furnace heating or the mode that electrically contacts heating with diameter in the prior art is 780 ℃～900 ℃; And make heated steel wire under 780 ℃～900 ℃ temperature, keep 10 seconds～2 minutes (time that the big steel wire of its diameter keeps should greater than the little steel wire of diameter); Can achieve quick austenitizing like this; Steel wire after will heating then puts fast in the salt bath that isothermal keeps after 1 second～20 seconds in the salt bath of 300 ℃～480 ℃ of temperature into, and salt bath or the lead bath isothermal of again this steel wire being put into 500 ℃～600 ℃ of TRs keeps taking out naturally cooling after 20 seconds～1 minute, can accomplish the thermal treatment process to the sorbitizing of this high-carbon carbon steel wire like this; And can the group of acquisition be of a size of 1mm～2mm, interlamellar spacing is that the wireline of 10nm～70nm sorbite tissue is with high-carbon carbon steel wire product.
