Description
Technical field
The utility model belongs to process for making and equipment technical field is used in transportation, particularly provides a kind of ladle whole process to add a cover and has used slim insulation cover.
Background technology
The steel mill molten steel places the bucket formula vessel of inner lining refractory more in transport process be in the ladle, ladle is suitable for reading in most cases all to be opened wide, it is very big by the heat waste that its upper oral part radiation and convection current produce that red-hot molten steel or pour returns the empty ladle red heat liner that is subjected to steel, and in the increase of ladle mouth the insulation cover of positioning and guiding being arranged so is the best approach of the most direct these molten steel of the most effective minimizing and the physics of anti-material heat waster.
The utility model is added a cover this process matching with ladle whole process, annotate recrement and hot repair with cover in its ladle intermediate links, make the hinge type insulation cover become first-selection, it is big that fixedly suspension centre on this insulation cover takies headroom, add and consider to wrap the activity space that mouthful dry slag must be reserved suspension hook, clad and mechanism's thickness thereof generally are not less than 500mm, add bag mouthful thick 150mm of slag and bag mouth, the safe space 100mm of clad self-deformation, three's addition requires a bag mouthful top to have 750mm to be only reasonably headroom, but most refining station (LF of steel mill, CAS, RH and Argon hello silk station) the effective headroom above the ladle mouth is all less than 450mm, headroom is generally also only about 550mm at the bottom of Bao Kou and the beam when ladle rotates for it car door type suspension hook, and this just requires clad and mechanism's thickness thereof to be no more than 300mm; The ladle of the above thickness of 500mm lid self weightening finish is a lot of in addition, about about 5 tons, easily make the frequent overload operation of active service overhead traveling crane, and the following ladle lid own wt of 300mm can be controlled in 3 tons, more easily allows the active service overhead traveling crane be operated under the rated load.The slim insulation cover of this patent can solve the short difficult point problem of above-mentioned headroom well, can drop to minimum to the negative effect of adding a cover the back weightening finish simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of ladle whole process to add a cover and uses slim insulation cover, has solved the short difficult point problem of headroom, can drop to minimum to the negative effect of adding a cover the back weightening finish simultaneously.
The utility model comprises thin cover body, flat cross section Assembly of pin, hangers, suspension centre, the anchoring piece of anti-material the and refractory material.As Fig. 1, shown in 2 and 3.
Approaching and covering body is steel construction piece, two-layer up and down, be the frame structure layer above, following central part is that the refractory material that steel construction surrounds is filled the chamber over against the zone of ladle mouth upper edge size, for fastness and the stability that keeps anti-material, chamber medial surface and end face have been arranged anchoring piece, two-layer total thickness is 250-300mm, with reference to Fig. 1,2 and 3, hangers, suspension centre is fixedly mounted on thin four jiaos of sides covering body, hangers is installed in the side that Fig. 2 ladle is tumbled and is with, the flat cross section Assembly of pin is installed on the ladle, plays location and guide effect, and it was again a hinge axis when hangers rotated about it in the deslagging operation.97.5～98 ° of layouts of the flat cross section of flat cross section Assembly of pin, the insulation cover hangers 3 of inverted U notch arranges that with angle the U type notch oral area of hangers is downward, and two legs have the discrepancy in elevation, and the leg in the outside will grow 100～160mm.
Slim insulation cover thickness is 250-300mm, has both satisfied the adiabatic heat-insulation function, satisfies the requirement that technology is passed through refining station (as LF, RH, CAS etc.) about ladle with cover again, and thin lid adds that the detent mechanism weightening finish on the ladle can be controlled in about 3 tons.
Slim insulation cover can substitute with the structure that adopts Fig. 4, and two suspension centres of hangers one side replace with unidirectional swing suspension centre in four suspension centres, as the clockwise any barrier of dodging its top of swinging among Fig. 5.
Slim insulation cover can also adopt the structure of Fig. 7 to substitute, and four suspension centres all adopt unidirectional swing suspension centre, dodge any barrier on its top as counter-clockwise swing among Fig. 8; Hangers is oppositely installed, and the installation site adjusts to the both sides of suspension centre, and 82～82.5 ° of direction oral areas of hangers U type notch are downward, and two legs have the discrepancy in elevation, and the leg on right side will be grown 150～160mm; This hangers is unpowered self-locking hangers, interior cogged rackwork, tooth bar is tumbled to rotate to horizontal sextant angle before insulation cover is with ladle and serve as the flat bearing pin of the automatic shutoff of dead bolt after 45 °, prevent insulation cover from the slippage of inverted U notch, equally the ladle hypsokinesis translate into horizontal sextant angle less than 15 ° after tooth bar automatically reply original position and abdicate the bearing pin slideway; Thin insulation cover body, little insulation cover and the hinge that covers this body and function band U type mouth substitutes, with reference to Fig. 9, be that the bottom increases a little insulation cover that is used for about 1000mm * 1200mm of slag stream discharge, little insulation cover is nested in the insulation cover body of being with U type mouth and by hinge and flexibly connects.
The utility model compact conformation is reasonable, occupies little space, and layout is got up flexible, is particularly suitable for technological transformation project; Be equipped with the suitable laying mechanism that installs additional and take off, add the short outstanding and difficult point problem of head room that runs in the cover process popularization process thoroughly solving ladle whole process.
