Embodiment 1

[0051] like figure 1 , 2 As shown in , 3, the method of this scheme is to process the large-diameter bolts arranged in a ring into several wholes through the upper and lower anchor plates of the bolts for block processing, and use the upper and lower ring plates to connect, the overall stability is good, and the bottom of the bolt anchor plate is used A technique in which a support frame is used to complete the installation process. This scheme is suitable for the installation of large-diameter and high-precision embedded bolts on the foundations of blast furnaces, hot blast stoves, desulfurization towers, and CDQ ovens in metallurgical engineering.

[0052] The present invention divides n bolts into several parts, such as figure 2 , 3 , each part is connected together by the upper fixed ring plate 4 and the lower fixed ring plate 5 in a ring, the self-weight of the large-diameter anchor bolt 1 can improve its stability, and the quality of a single one often reaches 200kg,...

Abstract

The invention discloses an annular bolt installation method for a metallurgical industry furnace body, and belongs to the field of metallurgical engineering equipment installation and civil engineering cooperation. For the problems that in the prior art, the device installation is complex, precision is poor and labor hours are consumed, the annular bolt installation method for the metallurgical industry furnace body is provided. The annular bolt installation method includes the following steps that A, a bolt system is manufactured and segmented, and all bolts are divided into multiple symmetrical systems, and each system comprises multiple bolts and fixing anchor plates; B, fixing welding pieces of supporting frames below the bolt systems are embedded in a base concrete cushion layer in advance and poured on the upper surface of the cushion layer; C, each bolt supporting frame is arranged in place along the circumference, the top elevation of each bolt supporting frame is adjusted, and the bolt supporting frames are welded to all embedded parts around the bolt systems in the cushion layer; D, the bolt systems are sequentially installed on the supporting frames, and the top elevation and perpendicularity of the foundation bolts of all the system bodies are fine adjusted; E, the bolt system bodies are welded and installed to form the whole annular bolt system; F, the bolt system bodies are subjected to concrete pouring; and G, acceptance inspection is conducted. The annular bolt installation method is easy to install, high in precision and high in efficiency.

Description

technical field [0001] The invention relates to the field of civil engineering cooperation for metallurgical engineering equipment installation, and more specifically, relates to a method for installing ring bolts in metallurgical industrial furnace bodies. Background technique [0002] Industrial furnaces are thermal equipment that use heat from fuel combustion or electrical energy conversion to heat materials or workpieces in industrial production. There are many kinds of industrial furnaces used in the metallurgical field. For example, large-scale annular heating furnaces are widely used in the field of metallurgical industrial furnaces. The annular heating furnace is a continuous heating furnace in which the billet is heated while moving on the annular rotating furnace bottom. When manufacturing a ring-shaped metallurgical industrial furnace, it is necessary to manufacture the ring-shaped external structure first. When manufacturing, it is necessary to use large bolts to...
