1830年 瑞典化学家塞弗斯托姆用塔贝里附近矿石炼生铁,分离出一个新元素,以女神Vanadis(凡娜迪丝)命名为vanadium(钒)。 同年,美国首先生产铅—锡合金涂层钢板。这种钢板具有优越的耐蚀性,特别是能抗石油制品的腐蚀,还有深冲成形的润滑性、可焊性。 同年,英国人维格诺利斯(C.Vignoles)、美国人史蒂文斯(R.L.Sterens)设计了断面为倒T形状的钢轨,于1857年在英国轧制成功。 1831年 毕克福德(W.Bickford)发明了导火索,
In 1830, the Swedish chemist Severstm made a new element from the ore near Taberih, separating it from the vanadis, Vanadis. In the same year, the United States first produced lead-tin alloy coated steel. This steel plate has excellent corrosion resistance, especially for anti-corrosion of petroleum products, deep drawing forming lubricity and weldability. In the same year, C.Vignoles, American R. R. Sterens, designed a rail with an inverted T-shape in cross section, and succeeded in rolling it in England in 1857. In 1831 W. Bickford invented the fuse,
