Abstract: A process for producing an enamelling steel sheet which comprises tapping molten steel with manganese content not more than 0.40%, lowering the carbon content in the molten steel to not more than 0.01%, adding titanium to the molten steel in an amount enough to obtain a titanium content between 0.01 and 0.3%, preferably between 0.03 and 0.1%, and also adding one or more of rare earth elements such as lanthanum, cerium, neodymium, praseodymium, and samarium (hereinafter called Rem) in total amount between 0.01 and 0.15%, preferably 0.02 and 0.12%, casting the molten steel into ingot or slab, hot rolling and then cold rolling the ingot or slab preferably at a cold rolling rate between 30 and 90% and then annealing the steel sheet.
Abstract translation: 一种搪瓷钢板的制造方法，其特征在于，以锰含量不大于0.40％的钢水进行脱硫，将钢水中的碳含量降低至0.01％以下，向钢水中添加足够量的钛， 钛含量在0.01和0.3％之间，优选在0.03和0.1％之间，并且还添加一种或多种稀土元素如镧，铈，钕，镨和钐（以下称为Rem），总量为0.01至0.15％ ，优选为0.02和0.12％，将钢水浇铸成锭或板坯，热轧，然后以30〜90％的冷轧速度冷轧锭坯或板坯，然后退火钢板。

Abstract: Hard and wear resistant deposited steel including martensite base and vanadium-carbide dispersed therein with the amount of vanadium of 32 to 40 percent in weight. A method for producing the hard and wear resistant steel, said method comprising steps of compression forming powder materials into a welding rod, melting the rod in a non-oxidizing atmosphere by means of a heat produced by an electric arc discharge, and heat treating the solidified substance thus obtained. The invention further provides a novel use of the steel thus produced.

Abstract: A process for incorporating a metal in steel by adding to molten iron or steel an intimate mixture, preferably in compacted form, of an oxide of the metal and carbon. The molten iron or steel is at a sufficiently high temperature to initiate a reaction between the carbon and the metal oxide to form, in situ, a metal carbide that readily disperses throughout the molten iron or steel.
