Description

Przedmiotem wynalazku jest stal do wytwarza¬ nia walców dla walcarek wielowalcowych, prze¬ znaczona na walce robocze i oporowe, zwlaszcza dla walcarek Sedzimira.The subject of the invention is steel to be manufactured rollers for multi-roll mills, trans marked on working and supporting rollers, especially for Sedzimir's rolling mills.

Walce dla walcarek wielowalcowych wytwarza sie ze stali zawierajacej oprócz wegla, zelaza i nie¬ uniknionych zanieczyszczen, jako zasadniczy sklad¬ nik stopowy chrom, oraz pewne ilosci manganu, krzemu, molibdenu i wanadu.He produces rolls for multi-roll mills made of steel containing in addition to carbon, iron and not avoided pollutants as an essential component chromium alloy nickel, and some amounts of manganese, silicon, molybdenum and vanadium.

Stal przeznaczona na walce robocze zawiera w procentach wagowych C — 1,10 do 1,40, Mn — 0,20 do 0,35, Si — 0,20 do 0,40, Cr — 10,00 do 13,00, Mo — 0,70 do 1,00 i V — 0,60 do 0,90. Natomiast stal przeznaczona na walce oporowe zawiera w procentach wagowych C — 0,35 do 0,60, Mn — 0,20 do 0,35, Si — 0,80 do 1,20, Cr — 4,50 do 6,00, Mo — 1,50 do 1,70 i V — 0,80 do 1,20.Steel intended for work rolls includes w percent by weight C - 1.10 to 1.40, Mn - 0.20 to 0.35, Si - 0.20 to 0.40, Cr - 10.00 to 13.00, Mo - 0.70 to 1.00 and V - 0.60 to 0.90. While steel intended for supporting rollers includes w percent by weight C - 0.35 to 0.60, Mn - 0.20 to 0.35, Si - 0.80 to 1.20, Cr - 4.50 to 6.00, Mo - 1.50 to 1.70 and V - 0.80 to 1.20.

Celem wynalazku jest zwiekszenie wytrzymalosci stykowej walców roboczych i oporowych walcarek wielowalcowych.The object of the invention is to increase the strength contact of work rolls and backing mills multi-roll.

Stal przeznaczona na walce robocze, zawierajaca wagowo 1,10 do 1,40% C, 0,20 do 0,35% Mn, 0,20 do 0,40% Si, 10,00 do 13,00% Cr, 0,70 do 1,00% Mo i 0,60 do 0,90% V, reszta Fe i nieuniknione zanie¬ czyszczenia wedlug wynalazku zawiera wagowo 0,80 do 1,20% Co i 0,02 do 0,10% Zr.Steel intended for work rolls, including by weight 1.10 to 1.40% C, 0.20 to 0.35% Mn, 0.20 up to 0.40% Si, 10.00 to 13.00% Cr, 0.70 to 1.00% Mo and 0.60 to 0.90% V, the remainder is Fe and the inevitable impurities cleaning according to the invention includes by weight 0.80 to 1.20% Co and 0.02 to 0.10% of Zr.

Stal przeznaczona na walce oporowe, zawiera¬ jaca wagowo 0,35 do 0,60% C, 0,20 do 0,35% Mn, 0,80 do 1,20% Si, 4,50 do 6,00% Cr, 1,50 do 1,70% Mo i 0,80 do 1,20% V, reszta Fe i nieuniknione za¬ nieczyszczenia, wedlug wynalazku zawiera wago¬ wo 0,80 do 1,20% Co i 0,02 do 0,10% Zr.Steel for supporting rollers, incl weight 0.35 to 0.60% C, 0.20 to 0.35% Mn, 0.80 to 1.20% Si, 4.50 to 6.00% Cr, 1.50 to 1.70% Mo and 0.80 to 1.20% V, the rest is Fe and the inevitable a According to the invention, the impurities are by weight with 0.80 to 1.20% Co and 0.02 to 0.10% of Zr.

Stal wedlug wynalazku wytapia sie wedlug do¬ wolnej, stosowanej dla-stali chromowej technolo¬ gii, wprowadzajac kobalt razem ze wsadem i cyr¬ kon w okresie odtleniania wytopu.The steel according to the invention is melted according to the bottom free technology used for chrome steel gii, introducing cobalt together with the charge and circus death during the smelting deoxidation period.

Gatunki stali wedlug wynalazku ilustruja po¬ nizsze przyklady.The steel grades according to the invention are illustrated by the following examples.

Ze stali zawierajacej wagowo C = 1,28%, Mn = = 0,25%, Si = 0,33%, Cr = 11,82, Mo = 0,87%, V = 0,82%, Co = 0,99% i Zr = 0,10% wykonano walce robocze o srednicy 130 mm, które wykazaly po obróbce cieplnej twardosc w granicach od 61 do 62 HRC. Walcami tymi przewalcowano na zim¬ no 1250 T blach.From a steel containing C = 1.28% by weight, Mn = = 0.25%, Si = 0.33%, Cr = 11.82, Mo = 0.87%, V = 0.82%, Co = 0.99% and Zr = 0.10% was done work rolls with a diameter of 130 mm we showed after heat treatment, the hardness ranges from 61 up to 62 HRC. These rollers were rolled in winter no 1250 T of sheets.
