Abstract
Использование: металлурги , может быть использовано дл изготовлени двухи трехслойных листов из углеродистых и легированных сталей со спецсвойствами. Сущность: способ включает получение слоистой заготовки, ее разогрев до 1100- 1300°С, гор чую и холодную прокатку полос, С целью повышени качества и увеличени выхода годного слоистую заготовку получают путем электродуговой наплавки сло нержавеющей стали на поверхность сл ба из углеродистой стали, при этом, перед наплавкой сл б подогревают до температуры наплавл емой поверхности 300-450°С и с ее увеличением по толщине сл ба к противоположной поверхности с температурным градиентом 0,4-0,6°С/мйн. 1 табл.Usage: metallurgists, can be used for the manufacture of two and three-layer sheets of carbon and alloy steels with special properties. Essence: the method includes obtaining a layered preform, heating it to 1100-1300 ° C, hot and cold rolling of strips. In order to improve the quality and increase the yield, a layered preform is obtained by arc welding of a stainless steel layer onto a carbon steel slab surface at the same time, before surfacing, the slab is heated to a temperature of the deposited surface of 300-450 ° C and with its increase in thickness of the slab to the opposite surface with a temperature gradient of 0.4-0.6 ° C / min. 1 tab.
Description
Изобретение относитс к области черной металлургии и может быть использовано дл изготовлени двух- и трехслойных листов из углеродистых и нержавеющих стэ- ле#.The invention relates to the field of ferrous metallurgy and can be used for the manufacture of two- and three-layer sheets of carbon steel and stainless steel #.
Цель изобретени - повышение качества биметаллических листов и увеличение выхода годного при использовании биметаллических заготовок нержавеюща сталь - углеродиста сталь.The purpose of the invention is to improve the quality of bimetallic sheets and increase the yield when using bimetallic billets, stainless steel - carbon steel.
Сл б из углеродистой стали Ст1 толщиной 200 мм и массой 25 т нагревают газовыми горелками, установленными с нижней его стороны, поддержива ее температуру равной 475°С. При нагреве нижней стороны сл ба за счет теплопередачи идет его прогрев по толщине. Нагрев ведут до достижени температуры на верхней стороне сл ба величины Тн 375°С, что соответствует градиенту температуры по толщине g 0,5°С/мм.A slab of carbon steel St1 with a thickness of 200 mm and a mass of 25 tons is heated with gas burners installed on its lower side, maintaining its temperature equal to 475 ° C. When the lower side of the slab is heated, its thickness is heated due to heat transfer. Heating is carried out until a temperature Tn of 375 ° C is reached on the upper side of the slab, which corresponds to a temperature gradient across the thickness g of 0.5 ° C / mm.
После этого сл б устанавливают на наплавочный станок и осуществл ют электродуговую наплавку сло нержавеющей стали 12Х18Н10 толщиной 20 мм на верхнюю сторону сл ба. Наплавку ведут под слоем флюса . .After that, the slab is mounted on the surfacing machine and the electric arc welding of the layer of stainless steel 12X18H10 with a thickness of 20 mm is carried out on the upper side of the slab. Surfacing lead under a layer of flux. .
Полученную заготовку разогревают в методической печи до температуры прокатки 1200°С и прокатывают на непрерывном широкополосном стане 2000 до толщины 3 мм с суммарным обжатием 98,6%. После удалени окалины гор чекатаную полосу подвергают холодной прокатке на четырехклетевом стане 1700 до конечной толщины 0,7 мм.The resulting billet is heated in a methodical furnace to a rolling temperature of 1200 ° C and rolled on a continuous broadband mill 2000 to a thickness of 3 mm with a total compression of 98.6%. After the scale has been removed, the rolled strip is cold rolled on a four-stand mill 1700 to a final thickness of 0.7 mm.
Варианты реализации способа, показатели качества биметаллических листов и выход годного приведены в таблице.Variants of the method, quality indicators of bimetallic sheets and yield are shown in the table.
Из таблицы следует, что в случае реализации предложенного способа обеспечиваютс наилучшие показатели качестваFrom the table it follows that in the case of the implementation of the proposed method provides the best quality indicators
