METHOD AND DEVICE FOR APPLYING AN ADJUSTABLE TENSILE-STRESS DISTRIBUTION, IN PARTICULAR IN THE EDGE REGIONS OF COLD-ROLLED METAL STRIPS

The invention relates to a method and a device for applying an adjustable tensile-stress distribution, in particular in the edge regions during the cold-rolling of metal strips (16), in particular metal foil, in order to reduce the risk of an excessive build-up of tension and cracks at the edges of the strip, which can lead as a negative consequence to cracks in the strip and to a reduction in production, and in order to improve the surface of the strip and its planarity, even for a relatively high strip displacement speed, and also to reduce strip trimming widths. To achieve these aims, at least one or a combination of two of the following measures are implemented: a) separation of lubrication and cooling of the working rolls by lubricating on the run-in side and cooling on the discharge side, b) additional influencing of the strip edges using a hot edge spray", in particular by spraying (21) rolling oil with differing temperatures in zones, c) use of a special cross-sectional configuration ...

MANUFACTURE OF METALLIC FOIL

PURPOSE: To stably manufacture foil by using work rolls having a specified range of surface roughness each in the final pass and rolling by work rolls having a surface roughness each larger than this in the upstream pass excepting the final pass. CONSTITUTION: In a manufacture of metallic foil, rolling is performed by work rolls having a surface roughness Ra<0.1μm each in the final pass and by work rolls having a surface roughness Ra≥0.1μm each in the upstream passes excepting the final pass. As occasion calls, the rolling is performed by work rolls having a surface roughness each nearly equal to the surface roughness of the foil required in the final pass. Since, in the upstream passes excepting the final pass, the surface roughness of each work roll has a value ≥0.1μm, the frictional coefficient between each roll and the foil becomes large. As a result, since the foil is prevented from lateral slip in a rolling process, the manufacture of the foil is stabilized. COPYRIGHT: (C)1989,JPO ...

КОМПЛЕКТ РАБОЧЕГО ИНСТРУМЕНТА ДЛЯ ПИЛЬГЕРНОЙ ПРОКАТКИ ТОНКОСТЕННЫХ ТИТАНОВЫХ ТРУБ ИЗ (α+β)-ТИТАНОВОГО СПЛАВА

Изобретение относится к трубопрокатному инструменту, а именно к рабочим инструментам для пильгерной прокатки тонкостенных титановых труб. Рабочий инструмент состоит из оправки и пары симметричных калибров. Оправка выполнена в виде металлического стержня круглого сечения с переменным диаметром, имеющего обжимную, предкалибрующую и калибрующую зоны. На цилиндрической поверхности калибра выполнен ручей переменного сечения. Профиль оправки в обжимной и предкалибрующей зоне имеет вогнутую кривую линию, форма которой определяется из условий равномерного распределения фактора трубной обработки по длине обжимного участка. Ручей переменного сечения имеет по длине обжимную, предчистовую и калибрующую зоны, уменьшающегося поперечного сечения. В обжимной и предчистовой зонах радиус центральной дуги выполнен с уменьшающимся значением, а в калибрующей - постоянным, равным радиусу готовой трубы. Коэффициент развалки в обжимной зоне составляет не более 3%, в калибрующей зоне не более 1%. Шероховатость поверхности ручья в калибрующей зоне имеет Ra 0,63…0,32 мкм. В результате повышается прочность трубы в радиальном направлении за счет формирования радиальной текстуры материала. 3 з.п. ф-лы, 4 ил., 1 табл.

HIGH PURITY Ta SHEET AND MANUFACTURING METHOD OF THE SAME

본 발명은, 용해 주조된 탄탈륨 잉고트 또는 빌렛트에 대해 최종 냉간 압연 후 재결정 소둔을 실시하기 전에, 내부의 국부적인 잔류응력을 제거하기 위해 재결정 온도 이하에서 일정 시간 동안 회복 소둔을 실시하는 것을 특징으로 하는 고순도 탄탈륨 판재 및 그 제조방법에 관한 것이다. The present invention is characterized by subjecting the melt-molded tantalum ingot or billet to recovery annealing at a temperature below the recrystallization temperature for a predetermined time to remove local residual stress before performing recrystallization annealing after the final cold rolling. It relates to a high purity tantalum plate material and a method of manufacturing the same. 이러한 본 발명에 의하면, 재결정 소둔 온도 이하에서 일정 시간 동안 회복 소둔 과정을 거침으로써, 근상의 모양 발생을 방지하고, 또한 재결정 개시시간이 균일해짐에 따라 결정립의 표준편차가 줄어들게 되어, 탄탈륨 판재의 결정입도가 균일하게 되는 효과가 있다. 예를 들어, 탄탈륨 판재를 스퍼터 타겟으로 이용할 경우, 탄탈륨 판재의 결정립 미세화 및 결정입도의 균일성으로 인해, 아킹이나 파티클의 발생을 억제할 수 있고, 그로 인해 스퍼터 성막의 품질을 향상시킬 수 있는 효과가 있다. According to the present invention, by undergoing a recovery annealing process for a predetermined time below the recrystallization annealing temperature, the appearance of the shape of the wound is prevented, and as the recrystallization start time becomes uniform, the standard deviation of the crystal grains is reduced, thereby determining the tantalum plate There is an effect that the particle size becomes uniform. For example, when a tantalum sheet is used as a sputter target, it is possible to suppress the occurrence of arcing or particles due to the grain refinement and uniformity of grain size of the tantalum sheet, thereby improving the quality of the sputter deposition. There is.

The present invention relates to a method of manufacturing an ultra-thin wide steel sheet. An embodiment of the present invention comprises the steps of preparing two or more plates; Applying a separating agent to the surface of the plate material; Stacking the plate to which the separating agent is applied, and then combining the plate to form a bonding portion to obtain a bonded plate; Removing a portion of the coupling portion of the coupling plate; Heating and rolling the bonding plate from which the bonding portion is partially removed; And separating the rolled bonded plate to obtain a steel plate.

Method of production of hot-rolled sheets from high-strength steel

FIELD: metallurgy. SUBSTANCE: invention relates to the field of metallurgy, namely to the production of thick steel sheets, used for structural elements operated in arctic conditions, for example, for the production of icebreakers and large-tonnage vessels. Method comprises producing a continuously cast billet of steel containing, mass%: carbon 0.07–0.12, silicon 0.15–0.40, manganese 0.3–0.9, the total content of chromium, nickel and copper is 3.4–4.2, the total content of vanadium, niobium and titanium 0.02–0.07, molybdenum 0.15–0.20, nitrogen is not more than 0.007, aluminum 0.01–0.05, sulfur not more than 0,003, phosphorus is not more than 0.010, iron and impurities remaining, at the same time, the resistance parameter of crack formation during P st welding does not exceed 0.28 %, austenization of the billet at a temperature of 1,200–1,230 °C, rough rolling to a thickness of 2×t±5 mm, where t is the nominal thickness of the sheet, caving of the rolls, finishing rolling with its completion at a temperature not lower than A r3 +100 °C and thermal improvement of the metal by quenching followed by tempering at a temperature of not more than 680 °C. EFFECT: obtaining a sheet thickness of 70 mm with a yield strength of at least 500 MPa, a high impact level at a test temperature of 60 °C below zero, including after mechanical aging, level of properties in the part of the temperature of the viscous-brittle transition T kb and the zero ductility temperature of NDT, as well as increased resistance to layered fractures under tensile stresses in the direction of thickness. 1 cl, 3 tbl РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 652 281 C1 (51) МПК C21D 8/02 (2006.01) C22C 38/16 (2006.01) B21B 3/00 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК C21D 8/02 (2006.01); C22C 38/16 (2006.01); B21B 3/00 (2006.01) (21)(22) Заявка: 2017119086, 31.05.2017 (24) Дата начала отсчета срока действия патента: Дата регистрации: 25.04. ...

Metal sheet cold rolling mill - has tension system with staggered rows of rollers on either side of stand

A cold-rolling mill, designed to produce thin and extra-thin sheet metals, consists of an uncoiling roller (2), a multi-cylinder roller stand (3,6,7) and a coiling roller (10). It is also equipped with a tensioning system (20,40) for the metal sheet, situated in between the uncoiling and coiling rollers (2,10) and independent of the two. The tensioning system is made up of a number of rollers (21,41) with adjustable speed to allow the desired traction to be achieved. The tensioning rollers (21,41) are set in staggered rows and are located on either side of the rolling stand to provide independent tension for the sheet metal before it enters and after is leaves the rolling stand. The number of tensioning rollers in each section is selected so as to achieve the required friction coefficient between the rollers and the sheet metal, and in each section there are at least two rollers. ADVANTAGE - Suitable for producing metal sheet from 1.0 mm thick down to 0.1 mm thick. (14pp Dwg.No.2/2)
