Problems solved by technology

Therefore, the transportation of materials is extremely inconvenient, and it is not easy to spread the construction in an all-round way, which greatly reduces the efficiency of construction. The construction period is long, and the quality is not easy to guarantee. Moreover, the distance between the trolley surface and the ground is more than 2m, which belongs to high-altitude operations, and there are many safety hazards.

Embodiment 1

[0013] An off-line construction method for a trolley, including leveling the trolley when entering the site, construction of refractory materials for the trolley, and off-line baking of the trolley. The specific steps are as follows:

[0014] 1. Placement and leveling of the trolley

[0015] The trolley is the hearth that bears the steel coil. It rotates in the furnace during the production process. Its elevation and surface flatness have very strict requirements. During the construction process, the trolley must be guaranteed to be flat and in place. When the trolley is in place, it is leveled with sleepers, and then wooden wedges are used to fine-tune the surface level.

[0016] The trolley is transported to the workshop by car, then hoisted to the ground by a crane, and then leveled and adjusted for elevation. In order to keep the surface of the trolley level, a level is used for detection during the leveling adjustment process. Select a point on the surface of the four c...

Abstract

The invention relates to the construction field of metallurgical equipment, particularly to a bench vehicle offline construction method, which comprises the following steps: leveling up a bench vehicle for approaching; applying resistance materials to the bench vehicle and roasting the bench vehicle offline, wherein when leveling up a bench vehicle for approaching, one point on the surface of four corners of the bench vehicle is selected respectively until four points reach the same height level; the procedure of applying resistance materials to the bench vehicle is that: laying bottom bricks, formwork support, pouring, and removing the formwork. The bench vehicle has beautiful appearance, good quality assurance, and can be used for batch construction and shorten the construction period.

Description

technical field [0001] The invention relates to the field of metallurgical equipment construction, in particular to an off-line construction method of a trolley. Background technique [0002] The off-line construction technology of the trolley is designed according to the national standards and regulations of the People's Republic of China "Code for Acceptance of Construction Quality of Industrial Furnace Masonry Engineering" (GB50211-2004) and "Quality Inspection and Evaluation Standards of Industrial Furnace Masonry Engineering" (GB50309-92) . Including trolley transportation, positioning, construction, baking and other processes. The trolley is the hearth structure of the modern annular furnace. Its refractory structure is mainly castable, and there are also lightweight refractory bricks and a small amount of high-alumina bricks. The construction process of the trolley is complicated, and special-shaped molds need to be made, and the construction is relatively difficult....
