Ultra-low headroom vehicle-mounted uncapping machine above the torpedo tank mouth

Abstract

The utility model relates to an ultra-low headroom vehicle-mounted uncapping machine above the mouth of a torpedo tank, which belongs to the technical field of molten iron transportation. In the case that the clearance above the torpedo tank mouth is not more than 460mm and the height of the nozzle slag at the tank mouth is within 150mm, it can still be covered and kept warm and normally uncovered and covered. The flat car track of the present invention consists of a circular track 1, a bow-shaped floating column leg 2 with casters, a horizontal track main beam 3, an arched beam 4 connected in the middle of the track beam, a driving device installation platform 5, a column leg 6 containing a hinged joint, and a hinged joint. Seat 7 constitutes. The present invention also comprehensively adopts the technology of automatic capping and uncapping of the single-drive support arm trolley 11, the technology of tank lid self-returning tank mouth heat preservation and anti-slip technology, the vehicle-mounted motor circuit multi-point current collection and multi-person operation technology. The advantage is that the torpedo cans are covered during the transmission and storage process, the project implementation has little impact on production, the promotion value is high, the accident plan is simple and practical, it saves energy, reduces the consumption of refractory materials and thermal insulation covering agents, and reduces environmental pollution. It is a direct and effective means to prolong the service life of torpedo tank refractory materials and reduce the turnover quantity of torpedo tanks.

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
