Embodiment Construction

[0022] Below in conjunction with specific implementation, the embodiment of the present invention is further described:

[0023] Such as figure 1 figure 2 image 3 The shown annular furnace steel beam processing method comprises the following steps:

[0024] Preparation work: make the formwork angle according to the design angle, install a platform, level the platform, fix the H-shaped steel operating frame 1 on the platform, and then load the H-shaped steel beam 2 according to the designed size and place it on the operating frame 1 , the placement direction is to make the two flange plates perpendicular to the platform, and the web parallel to the platform; then one end of the H-shaped steel beam 2 is fixed on the operating frame 1 with a plate clamp 3, and the other end is a free end, where it needs to be bent The H-shaped steel girder 2 is fixed with a fixing frame 4 .

[0025] Cutting: Draw the bending line on the H-shaped steel beam 2, and then use the cutting machin...

Abstract

The invention provides a method for machining a circular furnace steel beam. The method comprises the steps of arranging a platform, arranging two operating frames on the platform, then placing the H-shaped steel beam needing to be machined on the operating frames, cutting out two flanges at bend positions with flames, maintaining the cutting starting point not going beyond the edge of a web plate of the H-shaped steel and cutting edges facing upward, fixing cutting seams of the beam with a fixing frame and the platform, fixing one end of the beam with plate clams and the operating frames, fixing the other end of the beam with fixing blocks, preventing the beam from moving leftward or rightward, then heating the other sides of cutting edges of the flanges with a heating gun till the positions turn to russet, and jacking up the other end of the beam with a hydraulic jack. According to the method, the operation is convenient, materials are saved, the circular furnace steel beam can be machined manually at site by means of common tools, the strength of the steel beam can be guaranteed, and the welding stress can be reduced.

Description

technical field [0001] The invention relates to the technical field of steel structure manufacture and construction, in particular to a method for processing steel beams of an annular furnace. Background technique [0002] The silicon steel annular furnace is mainly used for the annealing treatment of silicon steel coils. The current steel beam of the silicon steel annular furnace is made of H-shaped steel. There is a bending line in the middle of the H-shaped steel and two sections form an obtuse angle. [0003] At present, the processing of this kind of silicon steel annular furnace steel beam mainly uses a steel bending machine for bending, which can only be carried out in a processing factory with complete equipment. Using this device for bending can save equipment configuration costs and machining costs. [0004] Another simple processing method is to cut the H-shaped steel into two sections, then assemble and weld according to the design angle, which wastes the cost of...
