Abstract
The utility model belongs to a wound-type refractory ladle heat-insulation cover, which mainly comprises a ladle cover shell and a refractory cotton blanket, wherein inverted F-shaped hoisting hooks are arranged at the inner top wall of the ladle cover shell at intervals, and the refractory cotton blanket is wound and hung in the ladle cover shell from the inside to outside along the ladle cover shell through the hoisting hooks. The refractory cotton blanket and the ladle cover shell are wound into an integral structure by a hoisting technology of the hoisting hooks, so that the service life of the ladle cover under a high-temperature environment can be greatly improved; and the wound-type refractory ladle heat-insulation cover has the advantages that the structure is simple, the heat-insulation and heat-dissipation effects are good, the installation and the maintenance are convenient, the use cost is low, and the service life is long.
Description
Technical field
The utility model belongs to the fire-resistant ladle heat insulation cover of a kind of wound form.
Background technology
In the production process of iron and steel enterprise, steel ladle has become indispensable production equipment, and the insulation problem that solves steel ladle is a technical barrier always.Method commonly used at present is to add insulation cover to ladle, and its performance mainly is to play heat preservation effect, promptly absorbs heat and dispels the heat.Consider that from the angle of heat absorption clad has the process of an intensification at normal temperature to keeping warm mode, the high more volume of the density of refractory material is big more, and programming rate is also just slow more, and the heat that is absorbed is also just many more; From the angle of heat radiation, the thickness of refractory material is more little, and heat-insulating property is poor more.At present the thickness of most of clads is usually all between 100mm～1500mm in process of production, but heat insulation effect is undesirable.
On the other hand, the environment for use very severe of ladle clad, the liquid steel temperature that it faced is all about 1600 ℃.General solid refractory material (like refractory cement or fire brick layer etc.); Be warming up to rapidly more than 1000 ℃ by the normal temperature state during use; Under the effect of thermal expansion, the inside of refractory material produces great internal stress with the surface, makes refractory material produce cracking, peel off; The Pyrology theory is referred to as " heat shake effect ", has shortened the service life of refractory material and ladle clad greatly.
To above-mentioned situation, use heat-insulating property and service life that fire-resistant cotton felt can improve insulation cover greatly instead.The density of at first fire-resistant cotton felt is less, about 260kg/m
3, little by 80% than the density of refractory cement.Have great deadweight advantage, can suitably strengthen clad thickness (extremely
300mm), to improve heat insulation effect.In addition, fire-resistant cotton felt is the cotton-wool state, and the fabulous heat resistanceheat resistant formation of shaking is arranged; The density of fire-resistant cotton felt of working together is very little, and its programming rate is very fast, can reach keeping warm mode at short notice; But it is very undesirable that the use of fire-resistant cotton felt is promoted, and major obstacle is that the technology of hanging is immature, and using more in the market is that modular is hung cotton felt; Every module only is fixed on the clad shell that steel plate processes with a screw rod, but under hot environment, oxidation takes place the nut on the screw rod easily; Degrade and make the monoblock module drop immediately after coming off, produce the steel plate that exposes the phenomenon that clad burns out is often taken place, reduced the service life of product significantly.
Summary of the invention
The purpose of the utility model is the fire-resistant ladle heat insulation cover of a kind of wound form of design; Adopt the suspension hook technology of hanging that fire-resistant cotton felt and clad shell are wound up as integrative-structure; Can increase substantially the service life of clad under hot environment, also have simple in structurely, preserving heat and radiating heat is effective; Installation and maintenance are convenient, the advantage that use cost is low and the life-span is long.
For this reason, the utility model mainly is made up of clad shell and fire-resistant cotton felt, and clad shell inner roof wall spacing distance is provided with reversed F-typed suspension hook, fire-resistant cotton felt through this suspension hook along center in the clad shell from inside to outside lash in the clad shell.Described reversed F-typed suspension hook is positioned at fire-resistant cotton felt.Said structure has reached the purpose of the utility model.
The utility model has the advantages that and adopt the suspension hook technology of hanging that fire-resistant cotton felt and clad shell are wound up as integrative-structure; Can increase substantially the service life of clad under hot environment, also have simple in structurely, preserving heat and radiating heat is effective; Installation and maintenance are convenient; The advantage that use cost is low and the life-span is long, the service life of the utility model, more traditional ladle heat insulation cover prolonged more than 5 times, and preserving heat and radiating heat is effective.

Fig. 2 is the three-dimensional profile status structural representation of the utility model.
Specific embodiments
As depicted in figs. 1 and 2, the fire-resistant ladle heat insulation cover of a kind of wound form mainly is made up of clad shell 1 and 3 on fire-resistant cotton felt.Clad shell inner roof wall spacing distance is provided with reversed F-typed suspension hook 2, fire-resistant cotton felt through this suspension hook along center in the clad shell from inside to outside lash in the clad shell.
Described reversed F-typed suspension hook is positioned at fire-resistant cotton felt, can prevent effectively that each reversed F-typed suspension hook from contacting the generation oxidation with high temperature.Described clad shell is processed by steel material.Described fire-resistant cotton felt is processed by the mineral wool material.
During manufacturing, reversed F-typed suspension hook spacing distance is welded on the clad shell inner roof wall, the spacing distance of adjacent reversed F-typed suspension hook is a benefit can fix fire-resistant cotton felt.With fire-resistant cotton felt along center in the clad shell from inside to outside on lash each suspension hook in the clad shell; Make fire-resistant cotton felt and clad shell be integrative-structure; Avoided the generation of the easy obscission of clad heat-insulation layer under hot environment; Improve the service life of clad under hot environment, reduced the labour intensity of line maintenance, practiced thrift the production cost of enterprise.
In a word, the utility model adopts the suspension hook technology of hanging that fire-resistant cotton felt and clad shell are wound up as integrative-structure, can increase substantially the service life of clad under hot environment; Also have simple in structure; Preserving heat and radiating heat is effective, and installation and maintenance are convenient, the advantage that use cost is low and the life-span is long.
