A quick installation device and method for a blast furnace refractory masonry equipment

By using a cross-shaped main load-bearing frame combined with an inner and outer rhomboid stabilizing structure for rapid installation during blast furnace construction, the overall assembly and hoisting of refractory lining equipment outside the furnace was achieved, ensuring precise positioning. This solved the problems of low efficiency, high safety risks, and poor versatility in traditional construction, thereby improving construction efficiency and safety.

AI Technical Summary

Technical Problem

The existing blast furnace construction process suffers from low equipment installation efficiency, high safety risks, complex construction organization, and poor versatility, making it difficult to achieve simultaneous installation of the furnace shell and preparation of equipment inside the furnace.

Method used

A rapid installation device for blast furnace refractory lining equipment is adopted. The device consists of a cross-shaped main load-bearing frame composed of two vertically intersecting steel beams, four support plates, and four stiffening plates, combined with an inner and outer rhomboid stabilizing structure. It is used for overall assembly and hoisting into place outside the furnace, avoiding high-altitude assembly.

Benefits of technology

It enables rapid and precise installation of refractory lining equipment, reduces safety risks, simplifies construction organization, improves construction efficiency, and has good versatility and economy.

Abstract

This invention relates to a rapid installation device and method for blast furnace refractory lining equipment. The rapid installation device includes two steel beams, four support plates, four lifting lugs, and four stiffening plates. The two steel beams are welded perpendicularly to each other to form a cross-shaped main load-bearing frame. Each of the four support plates has its two ends welded to the two steel beams and is located on the outer side away from the intersection of the steel beams. The four lifting lugs are fixedly installed at the four ends of the two steel beams. Each of the four stiffening plates has its two ends welded to the two steel beams and is located on the inner side near the intersection of the steel beams. This invention features a simple and reasonable structure, is easy to manufacture, and achieves high load-bearing capacity and high stability through a unique "cross-frame + inner and outer double-rhomboid stable structure" design. Its application method innovates the traditional "in-furnace split installation" to "out-of-furnace overall hoisting," providing an ideal solution for efficiently and safely installing blast furnace refractory lining equipment.
