AI Technical Summary
Technical Problem
Existing methods for repairing converter track foundations suffer from problems such as poor thermal shock stability, insufficient structural support, easy oxidation of the steel reinforcement cage, and damage during slag cleaning operations, leading to equipment damage and affecting production continuity.
Method used
Precast reinforced concrete beams are used, and their posture is adjusted by positioning holes, positioning pins and wedges. Reinforcing bars are welded and filled with C60 grout to form a stable connection structure.
Benefits of technology
It improves the structural strength of the track foundation and the reliability of equipment operation, reduces construction time and costs, prevents equipment damage, and ensures production continuity.

Abstract
The invention belongs to the technical field of repairing of converter track foundations, and particularly relates to a converter track foundation repairing method. Comprising the following steps that (1) a solid reinforced concrete precast beam is manufactured according to the size of a track foundation repair position, steel bars at the two ends of the precast beam are exposed, and a plurality of positioning holes are formed in the bottom end of the precast beam; (2) a notch is excavated in the repairing position of the track foundation through an excavator, the reinforcing steel bars are exposed, holes are formed in the bottom end of the notch according to the positions of the positioning holes, and positioning pins are placed; and (3) the precast beam is hoisted to the notch, the positioning pins are aligned and inserted into the positioning holes, wedge-shaped iron is inserted into the bottom end of the precast beam, and the posture of the precast beam is adjusted so that the precast beam can be aligned with the original foundation. The prefabricated beam is manufactured in advance, the repairing cost is low, the strength meets the use requirement in advance, the steel protection plate is arranged, the prefabricated beam is prevented from being scratched and damaged when a forklift cleans accumulated slag, and the operation reliability of equipment is improved.
