Description
" Armeringsstål" "Reinforcing Steel"
Denne oppfinnelse angår stål for armeringsformål.. Spesielt angår den en sveisbar armeringsstang som er fremstilt ved varmvalsing. This invention relates to steel for reinforcement purposes. In particular, it relates to a weldable reinforcing bar produced by hot rolling.
Stålet har en høy flytegrense, og det relativt lave innhold av silisium i stålet gjør det mulig å oppnå et høyt primærprodukt-utbytte ved fremstillingen av stålet. Videre kan stålet fremstilles i en basisk oksygenovn og deretter støpes kontinuerlig uten altfor store støpeproblemer på grunn av den kombinasjon av silisium og aluminium som anvendes. The steel has a high yield strength, and the relatively low content of silicon in the steel makes it possible to achieve a high primary product yield when manufacturing the steel. Furthermore, the steel can be produced in a basic oxygen furnace and then cast continuously without excessive casting problems due to the combination of silicon and aluminum used.
I henhold til et trekk ved oppfinnelsen består en sveisbar armeringsstang som er dannet ved varmvalsing, av et stål inneholdende According to a feature of the invention, a weldable reinforcing bar formed by hot rolling consists of a steel containing
mellom 0,15 og 0,27% karbon,between 0.15 and 0.27% carbon,
mellom 1,10 og 1,50% mangan,between 1.10 and 1.50% manganese,
mellom 0 og 0,14% silisium,between 0 and 0.14% silicon,
mellom 0,003 og 0,02% nitrogen,between 0.003 and 0.02% nitrogen,
mellom 0,05 og 0,20% vanadium,between 0.05 and 0.20% vanadium,
mellom 0 og 0,05% aluminium,between 0 and 0.05% aluminum,
under 0,05% fosfor, ogbelow 0.05% phosphorus, and
under 0,05% svovel,below 0.05% sulphur,
resten jern og uunngåelige forurensninger, hvilket stål har enthe rest iron and inevitable impurities, which steel has a
2 2 2 2
flytegrense på minst 400 Newton/mm (N/mm ).yield strength of at least 400 Newton/mm (N/mm).
Ifølge et annet trekk ved oppfinnelsen inneholder en sveisbar armeringsstang som er dannet ved varmvalsing, alle de elementer som er angitt i det foregående avsnitt i de mengder som der er angitt, og har dessuten et niob-innhold mellom 0 og 0,04%, idet resten er jern og uunngåelige forurensninger, hvilket stål har en flytegrense på minst 400 N/mm 2. According to another feature of the invention, a weldable reinforcing bar formed by hot rolling contains all the elements indicated in the preceding paragraph in the quantities indicated there, and also has a niobium content between 0 and 0.04%, as the rest is iron and unavoidable impurities, which steel has a yield strength of at least 400 N/mm 2.
Vanadiuminnholdet kan være av et snevrere område, nemlig 0,05-0,15%. The vanadium content can be of a narrower range, namely 0.05-0.15%.
Karboninnholdet i stålet kan være i området 0,16-0,22%. Manganinriholdet i stålet kan være i området 1,10-1,50%. Silisiuminnholdet kan være i området 0,02-0,12%. Nitrogeninnholdet kan være i området 0,010-0,016%. The carbon content in the steel can be in the range 0.16-0.22%. The manganese content in the steel can be in the range 1.10-1.50%. The silicon content can be in the range 0.02-0.12%. The nitrogen content can be in the range 0.010-0.016%.
Vanadiuminnholdet kan videre være begrenset til området 0,05-0,09%. The vanadium content can further be limited to the range 0.05-0.09%.
Stangen kan ha en ensartet overflate eller den kan alternativt være valset med ribber. The bar can have a uniform surface or it can alternatively be rolled with ribs.
Stålemnet som valses til den nevnte stang, kan fremstilles ved kontinuerlig støping. Alternativt kan stålet støpes til barrer før valsingen. Den varmvalsede stang blir fortrinnsvis kjølt i det vesentlige bare i luft. The steel blank that is rolled into the aforementioned rod can be produced by continuous casting. Alternatively, the steel can be cast into ingots before rolling. The hot-rolled bar is preferably cooled substantially only in air.
Eksempler på typiske sammensetninger av stålet ifølge oppfinnelsen, sammen med data vedrørende stålets flytegrense og strekkfasthet, er gitt i den følgende tabell. Examples of typical compositions of the steel according to the invention, together with data regarding the steel's yield strength and tensile strength, are given in the following table.
De ovenfor angitte stål fremstilles hensiktsmessig i en basisk oksygenovn og støpes kontinuerlig til valseemner. Tilsetninger av vanadium eller niob blir i regelen foretatt i øsen. Stålets nitrogeninnhold kan også justeres ved tilsetninger av nitrogenholdige forbindelser til stålet i øsen. Disse valseemner blir deretter varmvalset i et kontinuerlig valseverk, The above-mentioned steels are suitably prepared in a basic oxygen furnace and continuously cast into rolling blanks. Additions of vanadium or niobium are generally made in the ladle. The steel's nitrogen content can also be adjusted by adding nitrogen-containing compounds to the steel in the ladle. These rolled blanks are then hot-rolled in a continuous rolling mill,
idet den resulterende stang kjøles med luft alene etter det siste trinn i valseverket. with the resulting bar being cooled with air alone after the last step in the rolling mill.
