Embodiment

[0027] The electric heating oil bath assembly method of the converter bearing proposed by the present invention includes three major processes of construction preparation, heating, hoisting and attachment installation;

[0028] Specifically include the following steps:

[0029] S1. Make the heating container 7. The heating container 7 is composed of the container wall 1, the container bottom 2, the container leg 3, the bottom plate reinforcement rib 4, the heating sheet 5 and the thermal insulation cotton 6. The container wall 1 is made of a steel plate with a thickness of δ12mm. A round pipe with a diameter of φ2000mm and a height of 1m; the bottom 2 of the container is welded and connected with the steel plate with a thickness of δ12mm and the wall 1 of the container; the leg 3 of the container is made of H350 steel, and the height is 200mm; the reinforcement rib 4 of the bottom plate is made of 16# channel steel It is formed by spot welding with the bottom 2 of the containe...

Abstract

The invention belongs to the technical field of building installation, in particular to a converter bearing electric heating oil bath assembly method, and solves such problems as nonuniform heating and nonuniform temperature in field installation of converter bearings in the prior art. The assembly method comprises three procedures of construction preparation, heating and lifting, and accessory installation; a bearing is lifted into a heating container; and after oil for heating is heated to reach a requested temperature by a heating device, the installation can be performed. The converter bearing electric heating oil bath assembly method is suitable for field installation of large bearings, and is small in occupied field and low in field requirement; and used equipment is simple in structure, easy to operate, precise in temperature rise control, fast in installation, high in efficiency, low in assembly cost, high in practicability, capable of being suitable for heat assembly of all steel refining converter bearings and broad in application prospect.

Description

technical field [0001] The invention relates to the technical field of building installation, in particular to an assembly method of an electric heating oil bath for a converter bearing. Background technique [0002] In recent years, the proportion of my country's converter steel output in the total crude steel output has been increasing. In 2003, my country's converter steel ratio was 82.4%. By 2013, this proportion had increased to 93%. The ratio is basically maintained at an average level of 7:3, and converter steelmaking is the most important method of steelmaking today. The installation of modern large-scale converters, especially the assembly of the support ring trunnion and the bearing, needs to be carried out on site, and the matching method is interference fit. From a practical point of view, the assembly forms of bearings include cold assembly, hot assembly and hydraulic assembly method, of which the cold assembly method is only suitable for assembly with small dia...
