Wall installing method for blast furnace casting house plant

Abstract

The invention discloses a wall installing method for a blast furnace casting house plant, a wall system can be integrally installed, aloft work is reduced, and installing efficiency is improved. The installing method comprises the steps that (1) an assembling site is determined according to the installing design size of a wall; (2) wall columns are placed in the assembling site, and it is ensured that the wall columns are on the same horizontal plane; (3) wall purlines, wall tension bars and a purline angle brace structure are installed sequentially; (4) after the wall system is installed, wall levelness and the straightness of the wall purlines are uniformly adjusted to ensure that requirements of a drawing and standards are met; (5) after assembly is completed, welding, accepting and supplementary brushing of an erosion resistant coating on welded portions are conducted sequentially; and (6) the assembled wall is hoisted and installed through a hoisting device. The wall installing method for the blast furnace casting house plant is few in aloft work procedure, safe, reliable, high in installing precision, good in welding quality, short in overall installing time, short in project schedule and low in cost.

Description

technical field [0001] The invention relates to a wall skin installation method, in particular to a blast furnace casting yard wall skin installation method. Background technique [0002] Known: The casthouse system of the blast furnace is an important auxiliary facility of the blast furnace. The molten iron produced by the blast furnace flows through the concrete platform iron ditch of the casthouse to the swing chute, and then is transported by railway, and the iron slag flows to the water slag tank or dry The slag pit and the casthouse platform have higher requirements for rainproof and waterproof, and the rainproof of the casthouse platform is mainly completed by the casthouse workshop. The wall columns, purlins and braces of the traditional casthouse wall skin system are installed by high-altitude bulk method. That is to install the wall pillars on the wall first, and then install the wall purlins and braces. All operations are completed at high altitude. [0003] The...

AI Technical Summary

Problems solved by technology

[0004] 1. The installation of wall skin columns, wall skin purlins, braces, etc. are all completed at high altitude, especially the installation of wall skin purlins, personnel can only stand on the purlins to operate, which is not conducive to the installation personnel's operation, increasing the high-altitude construction process, high-altitude The safety risk of installation operation increases, which is not conducive to the control of installation accuracy, poor quality, and high installation labor costs;

[0005] 2. The welding of purlins on the wall skin needs to be completed at high altitude. It is not easy to weld, and the welding quality is not easy to guarantee. There are many welding spots, and the welding wire is long, so the welding takes a long time and the efficiency is low.
