Description
The present invention relates to a kind of high-alloy wire and rod material production technology flow and mill train, belong to metal rolled method or milling train, and the fields such as layout of rolling plant.
The production procedure of existing high-alloy wire and rod material and wire and bar mill machine row, with and existing problem as follows.The high alloy material of our indication is not only those difficult high-alloy steel that is out of shape, as a class valve steel, Cr25Ni20 heat resisting steel etc. such as the high-speed steel of the various trades mark, alloy tool steel, high nickel chromium triangle two-phase welding rod steel, 21-4N, also comprise iron-base superalloy, nickel base superalloy.This class material is very important in national economy, but compares with general steel, and the annual demand of each material is not a lot, and specific to the line bar, the annual demand major part of each above-mentioned material is in the hundreds of ton in the scope of several kilotons.Yet bringing a high price of these high-alloy wire and rod material material, partly reaches 10～200,000 yuan/ton by general 2～50,000 yuan/ton.The characteristics of this class high-alloy wire and rod material of modern production are long flow processs, as the maturation process flow process of modern production high speed steel wire rod, are example with the high speed steel wire rod production line of KREFELD factory of German TEW company:
Smelt (15 tons of electric arc furnaces, 30 tons of charged magnetic stir electric arc furnaces, chemical analysis is decided carbon with infrared ray, sulphur, direct reading spectrometry W, Mo, Cr, V, microcomputer control, video data automatically) → method of making a bet casting (800,600,500 kilograms of sides, billet) → (2000 tons of fast forgings are split into 220 square billets in heating (the red commentaries on classics of steel ingot) → cogging, two sections of thermal cuttings) → (1000 tons of finish forges are split into 90～120 square billets in heating (the red annular furnace that changes over to) → secondary cogging, thermal cutting) → stress relief annealing → aligning → ball blast scales → ultrasonic wave, eddy current inspection → reconditioning, (totally 22 the branch four groups) tandem rolling that strips off the skin → walking-beam furnace heating → flat vertical miller group become medium and small-scale material and φ 5.5～28mm coil → the controlled atmosphere roller at the bottom of stove and controlled atmosphere bell-type furnace annealing.Through four pyrogene materials.
One class valve steel modern production technology such as 21-4N is similar with high-speed steel basically, but because hot-rolled finished product is not accurate round steel, will annealing after the hot rolling, pickling, cold-drawn, annealing, and production procedure is longer, more complicated.In addition, high nickel chromium triangle two-phase welding rod steel, heat resisting steel and high temperature alloy still will forge and reconditioning through too much fire before tandem rolling.
The deficiency of this long flow process is: 1, the high alloy material of forming by noble metal in process of production because excision cap mouth, repeatedly cutting head cutting tail, heating for multiple times scaling loss, repeatedly reconditioning and rolling in middle waste product, cause total lumber recovery lowly (40～70%) and processing charges height; 2, many fire heating and lumber recovery are low, cause unit product total energy consumption height; 3, the inside of steel ingot is micro-and slightly look defective and cause end product quality not high, as thick inhomogeneous, the thick net carbide existence of crystal grain, gas, be mingled with etc.; 4, the tandem rolling mode causes the tandem rolling parameter can not adapt to all steel grades, produces any specification product difficulty, produces the accurate line bar of all size difficulty, middle waste product is many.In a word, lack the desired flexibility of the various high alloy steel of production.
