Abstract
A production method for a large disc coil of a sucker rod belongs to the technical field of metallurgy and steel rolling and substantially comprises a shearing machine, an intelligent pinch roll, a looper, a bar wire-feeding device and two crimping machines. Each crimping machine is composed of a rotating scroll and a bar head clamping and guiding device for curling. The scroll is provided with a tensioning core column. After rolling, a sucker rod is rapidly cooled to 500-550 DEG C, and a disc coil can be formed through the crimping machines and is cooled to the room temperature through air so that the disc coil has excellent comprehensive performance. Fine-grain steel can be formed by controlling the temperature during the rolling process, a self-tempering process occurs after curling, and rolling stress of steel can be eliminated.
Description
Technical field
The invention belongs to metallurgy and technical field of steel rolling, relate to a kind of production method of sucker rod.
Background technology
At present, more domestic smelters have been succeeded in developing 20CrMoA, 30CrMoA and 25MnVRE steel series sucker rod and have been used round steel.Product has been radiated many petroleum machineries manufacturer.Petroleum machinery manufacturing enterprise has given abundant affirmation to product quality.Still mainly utilize rolling bar product-line organization to produce now, product is with the delivery of vertical bar state, but there are some problems in the bar production sucker-rod steel, and mainly show: crop is of poor quality, surface quality defectiveness (pitted skin, scuffing), and lumber recovery is low etc.The whole scales of customer requirements sucker-rod steel, it is about about 4% to cause lumber recovery to reduce thus, and uses the cold shears sheared edge, and horseshoe mouth, the first-class problem of triangle happen occasionally.
Once attempted adopting punch press to carry out the termination off-line secondary and replenish processing, but efficient is lower, hand labor intensity is big, and easily product quality is caused the secondary injury.
Summary of the invention
The objective of the invention is to disclose a kind of crop and surface quality improved, the method for bar products such as explained hereafter sucker rod is coiled in the employing that improves lumber recovery and scale rate greatly.
Coil production line greatly and be divided into three systems: the bar on-line temperature control system; Curling operating system; Coil the finishing system.
Bar temp control and induction system are positioned at by the Bar Cooling Bed line after the finish rolling, and the rolled piece after rolling cools off through cooling device fast, passes through crimping machine when being cooled to 500～550 ℃.In this temperature range, carry out to make the mechanical performance of coiling stocking acquisition excellence around volume.Operation of rolling control temperature can form fine-grained steel, and after curling a self tempering process is arranged, and can eliminate the rolling stress of steel, helps the further cold working of steel.
The operating system capital equipment that curls comprises cutter, " intelligence " pinch roll, kink device, bar thread feeding device, two crimping machines etc.Cutter in Scroll crimping machine porch, its effect are that head, the tail to bar implemented to shear; The effect of kink device be guarantee that no tension force curls and to every layer of bar evenly, neat yardage roll; The bar thread feeding device is with neat, consistent being rolled onto on the spool of bar, forms perfectly rod volume of profile; The effect of crimping machine is bar to be curled into coil.Crimping machine is made up of a spinning reel, a clamping of bar head and a guide and guards that is used to curl.Spool has the tensioning stem stem, so that unload volume.Two crimping machine alternations, wherein one is carried out bar when curling, and another unloads volume.Rolled piece is rolled into to be coiled, and air cooling is to room temperature then.After coiling Runout area and nothing being turned round the automatic bundling of rod volume, weighing, be transported to assigned address.
Scroll rod volume technology is the new technology in bar production field, has started to produce high-quality, ultra-compact, heavy nothing and turn round the precedent that round steel and square steel are coiled.Adopt bar products such as coiling the explained hereafter sucker rod greatly, through the supply of material of aligning product, can improve product lumber recovery and product scale rate again, shear cut lengths according to customer requirements, improve sucker rod end face shearing quality, economic benefit obviously improves.
The specific embodiment
Coiling production line greatly is behind finishing mill, to be configured in the line traffic control cooling system and to coil curling production line greatly.Be divided into three system areas: (1) bar on-line temperature control system; (2) curling operation area; (3) coiling machine is coiled Runout area.
Control of line bar temp and induction system are being worn the water tank outlet and are being curled between the district after the finish rolling.This line is positioned at by the Bar Cooling Bed line, is made up of a cover water-cooled case and conduit.In Scroll crimping machine porch, there is one crop/tail to cut.Rolled piece after rolling cools off through cooling device fast, passes through crimping machine when being cooled to 500～550 ℃.Through in this temperature range, carrying out to make the mechanical performance uniformity of coiling stocking acquisition excellence around volume.Process control temp can form fine-grained steel, and after curling a self tempering process is arranged, and can eliminate the rolling stress of steel, helps the further cold working of steel.
The curling capital equipment of distinguishing comprises: " intelligence " pinch roll curls with the no tension force of assurance and reaches the kink device to even, the neat yardage roll of every layer of bar.The bar thread feeding device, be used for bar neat, consistent be rolled onto spool, form perfectly rod volume of profile.Two crimping machine alternations, wherein one is carried out bar when curling, and another unloads volume.Each crimping machine is made up of a spinning reel, a clamping of bar head and a guide and guards that is used to curl.Spool has the tensioning stem stem, so that unload volume.Rolled piece is rolled into to be coiled, and air cooling is to room temperature then.
After coiling Runout area and nothing being turned round the automatic bundling of rod volume, weighing, be transported to assigned address.
Scroll rod volume technology is the new technology in bar production field, has started to produce high-quality, ultra-compact, heavy nothing and turn round the precedent that round steel and square steel are coiled.It coils distinctive fault-free uncoiling characteristic, makes Scroll coil directly fed downstream operation, has practiced thrift the conversion cost significantly.Rod volume Design of Production Line production capacity is that 100 tons/hour, maximum speed are 35 meter per seconds, can produce diameter and be the 12-52 millimeter, do not have and turn round round steel and wear but spiral of water-cooled, roll up heavy up to 3.5 tons.Its concrete characteristics are:
1. bar is coiled temperature control parameter greatly, and different specifications is slightly variant.Being provided with of cooling control technology parameter such as start rolling temperature, finish to gauge speed, the temperature of curling must accurately be controlled the interval temperature of austenite phase transformation and change the concluding time; Add pearlitic structrure, intensity and good plasticity index so that obtain suitable ferrite, make to coil to have excellent comprehensive performances.
2. bar coiling machine control parameter is relevant with product specification and finish to gauge speed.The parameter of setting need guarantee not have tension force curls and to every layer of bar evenly, neat yardage roll.In curly course, do not allow to produce product defectses such as impression, scratch, form perfectly rod volume of profile.Concrete setting value is seen table 1.
