Description

Lifting device for welding of hot rolling roller way shaft head of ESP production line

Technical Field

The utility model relates to an ESP production line technical field especially relates to an ESP production line hot rolling roll table spindle nose welding is with hoisting device.

Background

The ESP production line is developed on the basis of ISP technology of demark corporation, a continuous casting machine in the production line adopts a parallel plate type straight-arc crystallizer, a casting blank guide adopts a casting and rolling structure, the casting blank is directly fed into a primary rolling mill to be rolled into a medium plate through liquid core reduction, then the medium plate can be sold off line through shearing, a plate blank which is not off line enters five finish rolling mills to be rolled into thin strip steel after induction heating, and the thin strip steel is curled into a strip coil after cooling. The ESP process production line is compact in arrangement, does not use a long heating furnace or a Cramera furnace, has the total length of only 190m, and is the shortest continuous casting and rolling production line in the world.

The ESP production line is a 1 st strip coil hot rolling full-continuous production line which can finish hot steel to an underground coiler within 7min, and the original ISP thin slab continuous casting and rolling production line needs 15min from the casting of the hot steel to the production of finished strip steel; the ESP technology is rolled at high temperature, so that the uniformity of the microstructure of the product is improved, and the performance of the product is improved; the whole production line is not more than 190m from the continuous casting to the finished product coiler, is very compact and belongs to an ultra-short flow, the equipment investment and the plant investment are both reduced, and the yield is relatively improved; can produce high-quality ultrathin strip steel, can partially replace cold-rolled products, and can be directly subjected to acid pickling and galvanizing; in the aspect of energy conservation and environmental protection, the energy consumption of the ESP is reduced by about 25-30% compared with that of the ISP, and is reduced by about 40% compared with that of a traditional hot strip mill. Associated with the reduction in energy consumption is a direct or indirect reduction in greenhouse and harmful gas emissions, by 40% to 50% when producing typical gauge coil stock and by 65% to 70% when producing thinner gauge coil stock. In terms of water consumption, the water consumption is reduced by 80 percent compared with the best traditional coil production mode.
