从1983年开始,二汽有关专业厂都推广应用了新型炉用耐热钢种,全厂选定七个钢种,其中二个品种定为厂标,五个品种定点生产,1983～1985年共推广应用新耐热钢242.5吨。炉用构件一般提高寿命0.5～2倍,目前全厂炉用耐热钢消耗指标比1983年下降38.18％。我厂现有各类工业炉921台,这些热工设备承担着铸件、锻件以及其它零件的熔炼、加热、退火、正火、渗碳及烘干等生产过程。动能消耗占全厂能耗42.5％,平均热
Since 1983, the two steam-related professional factories have promoted the use of a new type of heat-resistant steel furnace, the whole plant selected seven kinds of steel, two of which are designated as factory standard, five varieties of fixed-point production, 1983 to 1985 A total of 242.5 tons of new heat-resistant steel were promoted. Furnace components generally improve the life expectancy 0.5 to 2 times the current plant heat-resistant steel consumption index dropped 38.18% over 1983. There are 921 industrial furnaces in our factory. These thermal equipments bear the production process of melting, heating, annealing, normalizing, carburizing and drying of castings, forgings and other parts. Kinetic energy consumption accounted for 42.5% of the plant energy consumption, the average heat
