1.工程概况2004年某钢铁厂新建一大型车间,车间为36m和30m并联等高双跨,柱距12m,总长180m,柱高14m。在36m跨中设有100t/20t及75t/20t桥式吊车各一台,在30m跨中设有75t/20t及50t/20t桥式吊车各一台,全部采用全焊接实腹式吊车梁。吊车梁所用钢板由该钢铁厂铸钢车间自己生产的电炉钢锭送某一轧钢厂轧成,钢材的化学成分和物理性能优于同类平炉镇静钢。
1. Project Overview In 2004 a steel plant to build a large workshop, the workshop for the 36m and 30m parallel double span, column spacing 12m, total length 180m, column height 14m. There are one 100t / 20t and 75t / 20t overhead crane in the 36m span and one 75t / 20t and 50t / 20t overhead crane in 30m span, all fully welded solid abdominal crane beam. Crane beam steel used by the steel plant in the steel shop to produce their own electric furnace steel ingot rolling to a rolling mill, the chemical composition and physical properties of steel superior to the same flat hearth steel.
