47 strip (n.) A thin, flat piece of steel that is generally narrower than sheet steel and the gauge is monitored more carefully. It may be cut from a steel sheet with a slitting machine. S108
“There are 4 principal hot rolled finished flat products: bars, plate, hot rolled strip and hot rolled sheet. Dimensions particularly thickness and width are the principle bases of classification.” S125
tira (s.f.) “As tiras laminadas a quente são usadas na produção de tubos que requerem boa soldabilidade e tenacidade, e na indústria automotiva, que exige aço de boa conformabilidade. São produzidas em laminadores contínuos de tiras a quente.” S126
48 structural steel (np)
Steel product group that includes I-beams, H-beams, wide-flange beams and sheet piling. These products are used in the construction of multi-story buildings, industrial buildings, bridge trusses, vertical highway supports, and riverbank reinforcement. S111
“Structural shapes distributed by L.B. Foster Piling are rolled to conform to the latest ASTM Structural Steel Specification. Rolling and cutting tolerances shown in this catalog are in conformance with ASTM A6/A6M.” S127
aço estrutural (SN)
“O uso do aço estrutural na construção civil no Brasil – embora mais recente e em pequeno volume, quando comparado ao que ocorre nos Estados Unidos, Japão e países da Europa – vem crescendo de forma consistente.” S128
49 temper mill (np)
A type of cold-rolling mill, usually with only one or two stands, that finishes cold-rolled, annealed
“A temper mill rolls the strip with controlled extensions to improve flatness, remove yield point elongation and
laminador de encruamento (SN.)
“O material é recozido, processo que irá garantir a boa conformabilidade, e depois passa pelo

provide a uniform surface. S130
laminador de encruamento (LE) responsável por elevar um pouco as características mecânicas e de conferir um bom acabamento superficial.“ S131
50 tensile strength (np)
The greatest longitudinal stress steel can sustain without breaking. S132
“The developed cast steel had a tensile strength over 650N/mm2 and a Charpy energy absorption of more than 100J at 0 °C. The new cast steel was put through trial production verification tests for application to the super-mega frames of buildings.” S133
limite de resistência à tração (SN)
“Os aços de alta resistência e baixa liga são utilizados toda vez que se deseja: elevar a relação do limite de escoamento para o limite de resistência à tração , sem perda apreciável da ductilidade.” S134
51 tin plate (np) Thin sheet steel with a very thin coating of metallic tin. Tin plate is used primarily in can making. S129
“The unexpected growth of the tin plate industry after 1890 was due chiefly to the cheapening of the fundamental raw material, sheet bars.” S135
folha-de-flandres (SN)
“Folha-de-flandres para produção de embalagens para alimentos e bebidas é o principal item consumidor de estanho metálico, equivalente a cerca de 45% da oferta do metal.” S136
Também se usa apenas flandres (s.m)
52 width
(n.)
The lateral dimension of rolled steel, as opposed to the length or the gauge (thickness). If width of the steel strip is not controlled during rolling, the edges
“Because steel mills have limited flexibility as to the widths of the sheet that they produce, service centers normally will cut the sheet for the customer.”
largura
(s.f)
“A morfologia vista nessa figura foi semelhante à observada em todos os pontos ao longo da largura da tira (operação, centro e motor), a qual se mostra um

must be trimmed. S137
S111 tanto quanto diferente das observadas nos laminados a quente de aços convencionais de baixo C.” S138
53 work roll (np) Two smaller rolls of a four-high stand of the Weirlite Mills, Tandem Mills, and the Temper Mills. These rolls, through the use of hydraulic pressure, are responsible (along with the backup rolls) for the shape of the steel. S139
“Prediction of temperature distribution within work rolls during the hot strip rolling process is of great importance to mill designers because of the significant role it plays in the products dimensional accuracy and roll life.” S140
cilindro de trabalho (SN)
“São vários tipos de cilindros de laminação, sendo que os envolvidos nesse projeto são os chamados cilindros de trabalho para laminadores de tiras (de aço) a quente.” S141
