Ultra-low clearance vehicle-mounted uncovering machine above torpedo ladle opening

Abstract

The invention discloses an ultra-low clearance vehicle-mounted uncovering machine above a torpedo ladle opening, and belongs to the technical field of molten iron transportation. Under the conditions that the clearance above the torpedo ladle opening is not greater than 460 mm and the slag height of a ladle opening water nozzle is within 150 mm, the heat preservation through covering and normal uncovering and capping can still be performed. A flat car track is composed of an annular track 1, an arch-shaped floating column leg 2 with trundles, a horizontal track main beam 3, a track beam middle connecting arch beam 4, a driving device mounting platform 5, a column leg 6 with a hinged joint and a hinged seat 7. According to the ultra-low clearance vehicle-mounted uncovering machine, a single-drive corbel trolley 11 automatic capping and uncapping technology, a tank cover self-weight homing tank opening heat preservation and anti-slip technology and a vehicle-mounted triboelectric track multi-point current collection and multi-person operation technology are comprehensively adopted. The ultra-low clearance vehicle-mounted uncovering machine has the advantages that the torpedo ladle is shielded by the cover in the conveying and placing process, the project implementation has small influence on production, the popularization value is high, an accident plan is simple and practical, and the ultra-low clearance vehicle-mounted uncovering machine is a direct and effective means for saving energy, reducing the consumption of refractory materials and heat preservation covering agents, reducing environmental pollution, prolonging the service life of the refractory materials of the torpedo ladle and reducing the turnover number of the torpedo ladle.

Description

technical field [0001] The invention belongs to the technical field of molten iron transportation, and in particular provides a vehicle-mounted uncapping machine with ultra-low headroom above the mouth of a torpedo tank. Background technique [0002] Molten iron is the main source of iron in the long-process steelmaking process of the converter, accounting for more than 80% of all steel materials. The physical heat brought in by the temperature of molten iron accounts for more than 50% of all heat sources in the steelmaking process. The higher the temperature of molten iron, the more iron-containing coolants such as steel scrap and iron ore can be used in the steelmaking process, and the steelmaking cost can be reduced accordingly. [0003] There are mainly two types of containers for transporting blast furnace molten iron to the converter workshop in modern converter steelmaking plants: torpedo-type torpedo tanks and traditional barrel-type torpedo tanks, both of which hav...

Problems solved by technology

[0006] On the basis of digesting the domestic torpedo tank and ladle capping technology, the company completely solves the problem that the existing torpedo tank capping machine has low tolerance for headroom, cantilever is too long in high temperature environment and the track deformation causes the cover body cannot be opened and the tank The problem of short life span of the cover is realized by the present invention
