Abstract
The invention relates to a mould used for electrode casting. The mould is provided with a main body which is provided with an inner cavity which is a big end down circular cone body or a prismatic shape. The big end down structure of the inner cavity of mould can reduce static pressure of the surface of molten steel, is beneficial to floating upward of gas and inclusion, and can reduce the solidification time of the molten steel; the mould can effectively control the filling ratio parameters when the electrode is in the process of electroslag remelting; therefore, the electrode casted by the mould has high density, and the fabrication cost of the mould is not increased.
Description
Affiliated technical field:
The present invention relates to a kind of electroslag remelting process that is used to cast and produce the mould of electroslag steel electrode used therein.
Background technology:
When producing bearing steel and be the electroslag steel, earlier electric furnace bearing steel or degassing bearing steel are made rod iron as electrode with electroslag remelting process, make electrode can be in the wash heat pond again the starting the arc melt concisely, and the subregion crystallizes into ingot.Electrode is that electroslag remelting process melting bearing steel is one of employed important source material of electroslag steel, so the quality of electroslag steel quality depends on the quality and the shape of electrode to a great extent, and the quality of electrode depends on its shape.
Prior art is only paid attention to the average-size and the casting form of electrode.As electrode being made the structure that profile is cylinder or prism, in order to satisfy relative cylinder charge in the esr process (area of electrode and crystallizer than), under the constant situation of cumulative volume, solve the problem of relative cylinder charge by the mode of adjusting electrode height.But when casting electrode, if the depth-width ratio of mould is excessive, can cause molten steel Surface Static Pressure power to increase, pernicious gas in the molten steel and field trash can not be got rid of by the mode of come-up in time, and then influence the quality of electrode; If the depth-width ratio of mould is too small, its cross section is bigger, in the solidification of molten steel process, because choosing divides the effect of crystallization, can produce component segregation, and as-cast structure is fine and close inadequately, phenomenons such as field trash gathering, and then influence the quality and the billet yield of electrode.The form of existing casting electrode mainly comprises top-pour casting and following casting method, with regard to casting electrode, though casting method can be obtained effect preferably than top-pour casting to a certain extent under adopting, do not overcome when casting electrode, because the quality problems that the shape of electrode self is brought yet.From another point of view, because the relative cylinder charge parameter of electrode in esr process should be deferred to the rule that diminishes gradually by greatly, so just help controlling remelt speed and metal bath shape, and electrode adopts the structure of cylinder or prism to be difficult to reasonably adjust the relative cylinder charge parameter, and then can influence the quality of electroslag steel.
Summary of the invention:
The purpose of this invention is to provide the mould that a kind of casting electrode that utilizes the mode that changes electrode self shape to solve problems such as electrode quality and remelt speed control is used.
It is the up-small and down-big round platform body or the main body of terrace with edge shape that the mould that casting electrode proposed by the invention is used has an inner chamber.
The outer surface of the suitable for reading and end opening of described main body is respectively arranged with last convex edge and the following convex edge that extends radially outwardly, and the upper area of described main body outer surface and lower area are respectively arranged with the gudgeon of two symmetries, and gudgeon is cylinder or the prism that has the convex edge.
What the mould that casting electrode proposed by the invention is used adopted is truncated cone-shaped or terrace with edge shape inner chamber, in the process of casting electrode, because of the up-small and down-big structure of dies cavity can reduce molten steel Surface Static Pressure power, help gas and inclusion floating, and can reduce the setting time of molten steel, so, with the electrode density height of this kind die casting, even tissue, and can not increase the cost of manufacture of mould; In addition, the electrode that adopts this die casting to go out has certain tapering, and the electrode of this structure can be controlled the relative cylinder charge parameter effectively in esr process, and then can improve the quality of electroslag steel.
Description of drawings:
Accompanying drawing 1 is the outward appearance cross-sectional view of the embodiment of mould that uses of casting electrode proposed by the invention.
The specific embodiment:
Referring to Fig. 1, this figure provides the overall appearance structure of the embodiment of mould that casting electrode proposed by the invention uses.This mould comprises a main body 1 that has truncated cone-shaped intracoelomic cavity 11, suitable for reading and the end opening of main body 1 is respectively arranged with last convex edge 12 and the following convex edge 13 that extends radially outwardly, inner surface suitable for reading 15 for zero draft be used for being connected with cable cleat cylindrical, and regional at an upper portion thereof and lower area is respectively arranged with the gudgeon 14 of two symmetries.Gudgeon 14 can be arranged to have the cylinder or the prism of convex edge, and inner chamber 11 can also be arranged to the structure of terrace with edge body.Wherein, last convex edge 12 is the parts that are mainly used in the electrode demoulding, simultaneously also can be to the effect of playing reinforcing suitable for reading; The effect of rinforcement bar is played in following convex edge 13; Gudgeon 14 major functions are to be convenient to the handling mould.
