Abstract
The utility model provides a small furnace cover of a ladle refining furnace, which consists of a body, an electrode hole, a water inlet pipe and a water outlet pipe; the side surface of a stainless steel body of the water cooling structure is connected with a water inlet pipe and a water outlet pipe, at least one cylindrical electrode hole made of refractory material is arranged in the stainless steel body, and the outer wall of the refractory material is in an inverted cone frustum shape. The utility model discloses both can effectively prevent the deformation of body, greatly improve the life of little bell, make the life-span of little bell improve more than 5 years, the life-span extension of refractory material electrode hole is more than 6 months. Meanwhile, the problem that the electrode is broken due to falling of the refractory material due to crushing is solved, and production interruption or steel change from molten steel is avoided.
Description
Technical field
The utility model belongs to steel-making continuous casting refining unit field, is specifically related to the used small furnace cover of a kind of ladle refining furnace (LF stove).
Background technology
At present, the used small furnace cover of LF stove generally adopts refractory materials to make, and is embedded with reinforcing bar in refractory materials inside, thereby improves to a certain extent the work-ing life of small furnace cover.The work-ing life of this refractory materials small furnace cover is generally at 2-3 month.But because the integral body of small furnace cover all adopts refractory materials to make, so its intensity is low, very easily crackle occurs and damages.When larger crackle occurring, small furnace cover drops because refractory materials is broken easily, and the refractory materials that drops often can be pounded broken Electrode, causes production interruption or molten steel to change the steel accident, brings great threat for safety in production and quality product.
Summary of the invention
It is long that the utility model aims to provide a kind of life cycle, can avoid material to pound broken Electrode and the production that causes and the ladle refining furnace small furnace cover of quality accident.
For this reason, the solution taked of the utility model is:
A kind of ladle refining furnace small furnace cover is characterized in that, is comprised of body, electrode hole, water inlet pipe and rising pipe; Stainless steel body side at water-cooling structure is connected with water inlet pipe and rising pipe, is provided with the cylinder electrode hole that at least one is made with refractory materials in the body.
The refractory materials outer wall back cut diameter of described electrode hole is greater than lower port diameter, and namely outer wall belt is gradient.
The beneficial effects of the utility model are:
Because the utility model small furnace cover adopts stainless steel body and the refractory materials electrode hole of water-cooling structure, and the refractory materials outer wall of electrode hole is designed to truncated cone, making the refractory materials electrode hole get force way is stressed by become by pulling force, both can effectively prevent the distortion of body, greatly improve the work-ing life of small furnace cover, the small furnace cover bulk lifetime was brought up to more than 5 years, more than the life to 6 of refractory materials electrode hole month.Simultaneously, having eliminated drops because of the refractory materials fragmentation pounds the problem of broken Electrode, has stopped to produce to interrupt or molten steel changes the steel accident.
Description of drawings
Fig. 1 is ladle refining furnace small furnace cover vertical view.
Fig. 2 is ladle refining furnace small furnace cover electrode hole section of structure.
Among the figure: body 1, refractory materials 2, electrode hole 3, rising pipe 4, water inlet pipe 5, electrode hole refractory materials outer wall 6.
Embodiment
By accompanying drawing as seen, the ladle refining furnace small furnace cover of the utility model system is comprised of body 1, electrode hole 3, rising pipe 4 and water inlet pipe 5.Body 1 adopts stainless steel to process, and the side of stainless steel body 1 is connected with respectively a rising pipe 4 and a rising pipe 5, makes stainless steel body 1 form the metal shell of a water-cooling structure.Be provided with 3 columnar electrode holes 3 in body 1, electrode hole 3 adopts refractory materials 2 to build and makes.For improving the intensity of electrode hole 3, so refractory materials 2 outer walls of electrode hole 3 are made with constant slope, make refractory materials 2 form a rounding taper type that back cut diameter is large, lower port diameter is little.
Claims (2)
