对欧洲若干钢铁厂的能耗调查表明:在1985年,用于带钢热轧机的板坯如热炉的燃耗仍然很高,从2770MJ/t到1069MJ/t,而日本的标准燃耗才960MJ/t。对降低加热炉能耗来说,把连铸机出口坯所含有用热焓回收回来,是一个有力的措施。在日本用于热轧(带材和板材)的全部板坯,1983年已有55％是采取了热装的,其平均温度在300～500℃之间。在欧洲热装的进展仍很缓慢,热装率超过30％的厂家,1985年才有3家。热装能增加炉子生产率,节约加热炉用能。但要想充分利用这些好处,还必须满足一些基本条件,加热轧机和连铸机要相近,要能连续地生产出没有缺陷的连铸坯,以及连铸和轧钢的生产安排要衔接好等等。
Energy consumption surveys of several steel plants in Europe showed that in 1985, the fuel consumption of slabs, such as furnaces, for hot strip mills remained high from 2770 MJ / t to 1069 MJ / t while Japan’s standard burnup Only 960MJ / t. To reduce the furnace energy consumption, the caster export billet containing enthalpy recovered, is a powerful measure. In Japan, the entire slab used for hot rolling (strip and sheet) has been hot-clothed in 55% of the total in 1983, with an average temperature of 300 to 500 ° C. The progress of hot-suit in Europe is still very slow. The manufacturers with hot-fill rate over 30% only had 3 in 1985. Thermal loading can increase furnace productivity and save heating furnace energy. But to take full advantage of these benefits, there are some basic conditions that must be met: hot rolling mills and continuous casting mills are to be similar, continuous casting of blanks without defects, continuous casting and rolling production arrangements, etc. .
