Abstract
The utility model discloses a crucible used for a medium frequency induction furnace and a die for manufacturing the crucible, wherein, the crucible is made of refractory material and is of a bucket shape with a relatively thinner upper part and a relatively thicker lower part. The shape of the inside of the crucible is of a cone shape with a large upper part and a small lower part, and the shape of the outside of the crucible is cylindrical. The shape of the die used for manufacturing the crucible is of a reversed cone shape corresponding to the size of the crucible. The original bucket-shaped crucible with the cylindrical inside is changed into a crucible with a conical inside, therefore, the wall thickness at the lower part of the crucible is increased, meanwhile, the upper part of the crucible is thinned, the thickened part at the bottom of the crucible is the most seriously eroded part, and the part with weak erosion is thinned, so that the overall volume of the new crucible is not reduced, however, the service life of the crucible can be remarkably prolonged to above 40 tapping times from the former 30 tapping times.
Description
Technical field
The utility model relates to the equipment that uses in a kind of foundary industry, refers in particular to a kind of medium-frequency induction furnace crucible and mould thereof.
Background technology
Medium-frequency induction furnace is the smelting equipment that often uses in casting industry, during with medium-frequency induction furnace fusing smelting molten iron or molten steel a crucible need be set in induction furnace, places the material that needs fusing in the crucible.Crucible generally be by the user with the making of refractory lining material, their shape generally is to go up the round barrel shape of lower wall thickness unanimity.The wall of crucible has certain thickness, molten steel owing to crucible bottom in fusion process at first melts, and the just fusing at last of the molten steel on top, therefore crucible bottom heated time and be subjected to the time of molten steel etch all long, the furnace lining of bottom is subjected to the degree of etch just bigger, increase along with smelting time and heat, crucible inside will be become the lower end to become big cucurbit shape by etch, make the bottom attenuation of crucible, crucible might be able to not bear the pressure of molten steel generation and break in fusion process like this, in fusion process, cause runout, cause damage, produce bigger economic loss from making whole medium-frequency induction furnace.Therefore crucible is the parts that need most frequent replacing in the whole medium-frequency induction furnace.The furnace life of electric induction furnace is subjected to the restriction of crucible life, and crucible life is generally less than 30 heats in fusion process.
The utility model content
The utility model technical issues that need to address provide a kind of crucible of long service life, thereby reduce the maintenance frequency of whole medium-frequency induction furnace, improve casting production efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of medium-frequency induction furnace crucible, it is made by refractory material, and the shape of its outside is corresponding with the inner chamber of medium-frequency induction furnace, and its shape is that the wall thickness of the original relatively crucible in top approaches and the relative thicker tubbiness in bottom.Crucible inside be shaped as up big and down small taper, outside being shaped as is cylindrical.
In addition, the crucible mould that uses when making crucible is shaped as and the big or small corresponding back taper of the crucible of medium-frequency induction furnace.
Owing to adopted technique scheme, the obtained technological progress of the utility model is:
The utility model is that the crucible of cylindrical tubbiness changes the inner truncated cone that is into original inside, the wall thickness of the bottom of crucible increases like this, simultaneously with the top attenuate of crucible, the position of crucible bottom thickening is to be subjected to the serious position of etch, and be subjected to the light position attenuate of etch, can not reduce the whole volume of new crucible like this, but can significantly improve the service life of crucible, bring up to present 40 heats more than from original 30 heats that have only the service life that makes crucible.The intensity of crucible strengthens greatly simultaneously.
Description of drawings
Fig. 1 is the cross-sectional view of crucible of the present utility model;
Fig. 2 is a crucible mould schematic diagram of making crucible.
Wherein: 1, crucible, 2, the crucible mould.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details.
The crucible 1 that medium-frequency induction furnace of the present utility model is used is made by refractory material, and it is shaped as top and approaches and the relative thicker tubbiness in bottom relatively.Crucible inside be shaped as up big and down small taper, outside being shaped as is cylindrical.The wall thickness of the bottom of crucible increases like this, simultaneously with the top attenuate of crucible.
In addition, the crucible mould 2 that uses when making crucible is shaped as and the big or small corresponding taper type of the crucible of medium-frequency induction furnace.
Claims (3)
1, a kind of medium-frequency induction furnace crucible, it comprises the outside of being made by refractory material and the corresponding crucible of inner chamber of medium-frequency induction furnace, it is characterized in that: crucible being shaped as relatively thin and bottom, top thicker tubbiness relatively.
2, a kind of medium-frequency induction furnace crucible according to claim 1 is characterized in that the up big and down small taper that is shaped as of described crucible inside, and outside being shaped as is cylindrical.
3, a kind of medium-frequency induction furnace of making is characterized in that with the mould of crucible: make medium-frequency induction furnace being shaped as and the big or small corresponding back taper of crucible of medium-frequency induction furnace with the mould of crucible.
