Furnace bottom carbon brick building feeding construction method

Abstract

The invention discloses a furnace bottom carbon brick building feeding construction method and belongs to the technical field of blast furnace construction. The method includes the construction steps that a steel structure of a safety platform of the furnace bosh is fabricated and mounted; a steel structure of a furnace bottom carbon brick feeding system is mounted, specifically, a main beam, a ring beam, a radius beam and a longer-than-radius beam are mounted; a center shaft system of the furnace bottom carbon brick feeding system is mounted, specifically, a center shaft, a bearing, a sleeve, a radius beam connecting piece and a longer-than-radius beam connecting piece are mounted; circumference traveling devices are mounted, specifically, the radius beam circumference traveling device and the longer-than-radius beam circumference traveling device are mounted; a lifting mechanism is mounted, specifically, a radius beam electric hoist and a longer-than-radius beam electric hoist are mounted; and after mounting is finished, power-on trial operation is performed. The furnace bottom carbon brick building feeding construction method has the advantages that a double clock pointer type structural mode is adopted for furnace bottom carbon brick building feeding construction, and the two electric hoists can travel on the beams in the radial direction and meanwhile can move along a 360-degree circumference track under the action of the circumference traveling devices, so that furnace bottom carbon brick construction in various positions can be achieved and the disadvantages caused by traditional construction methods are avoided.

Description

Technical field [0001] The invention belongs to the technical field of blast furnace construction, and particularly relates to a construction method for furnace bottom carbon brick masonry and feeding. Two clock pointer structures are used to complete the furnace bottom carbon brick masonry and feeding construction, which solves the problem of large three-dimensional masonry. The problem of tonnage refractory materials is suitable for the construction and overhaul of refractory materials in the blast furnace. Background technique [0002] In view of the construction conditions of blast furnace masonry, a security platform is generally installed at the tuyere of the blast furnace, and a circular track and six parallel tracks are installed under the security platform. 8 electric hoists need to be installed. The equipment is invested more, the space is crossed, and the personnel are invested. Time-consuming and laborious work efficiency is low. [0003] In traditional masonry constru...

AI Technical Summary

Problems solved by technology

[0002] According to the construction conditions of blast furnace masonry, a security platform is generally set up at the tuyere of the blast furnace, and a circular track and six parallel tracks are installed under the security platform. Eight electric hoists need to be installed, which requires a lot of equipment investment, more space cross operations, and more input personnel. Time-consuming and labor-intensive work efficiency is low

[0003] In the traditional masonry construction operation, there are transportation dead angles, and the carbon bricks are not transported in place, which leads to the phenomenon of electric hoist cable pulling, which has potential safety hazards; various manpower and material resources are invested, the cost is high, and the total construction period is relatively long.
