钢管是一种经济钢材,在钢材生产中占重要地位。随着连铸坯和高效设备的大量使用,无缝管生产效率大大提高,生产成本大幅度降低,用连铸坯代替钢锭、代替轧坯是值得注意的动向。今年年初,我国第一台双流管坯水平连铸机在马鞍山钢铁公司通过了冶金部的技术 Steel pipe is an economical steel, which plays an important role in steel production. With the continuous use of slab and high-efficiency equipment, seamless tube production efficiency greatly increased, significantly reducing production costs, the use of slab instead of ingot, instead of rolling is a noteworthy trend. Earlier this year, China’s first Shuangliu horizontal tube continuous casting machine in the Ma On Shan Iron and Steel Company passed the Ministry of Metallurgical Technology
