Abstract
The utility model discloses a kind of trapezoidal graphite crucible and comprises graphite crucible body, described graphite crucible body is interior trapezoidal, trapezoidal graphite crucible bottom and trapezoidal graphite crucible bottom vertical, and trapezoidal graphite crucible wall top becomes angle α with trapezoidal graphite crucible wall bottom.Preferably, to become angle α with trapezoidal graphite crucible wall bottom be 2 ° ~ 5 ° on trapezoidal graphite crucible wall top.The utility model, a kind of trapezoidal graphite crucible, can realize material crucible is pressed to force resolution; The space on trapezoidal graphite crucible wall top is conducive to heat transmission; Increase flow of nitrogen gas space, improve the production technology of VN alloy; Improve the temperature of trapezoidal graphite crucible materials inside.
Description
Technical field
The utility model relates to a kind of graphite crucible, especially designs a kind of trapezoidal graphite crucible of producing for VN alloy.
Background technology
Graphite crucible has good thermal conductance and heat-resisting quantity, and in applied at elevated temperature process, thermal coefficient of expansion is little, to anxious heat, the certain anti-strain property of chilling tool.Corrosion resistance to acid, aqueous slkali is stronger, has good chemical stability.In metallurgical, casting, machinery, chemical engineering industry department, be widely used in the smelting of alloy tool steel and the melting of nonferrous metal and alloy, and have good techno-economic effect.
In VN alloy production technology, use graphite crucible, in VN alloy production process, except heating, heat-insulation system, the use of graphite crucible is for the distribution of nitrogen, and the external force in opposing production process all has a great impact.Therefore, need to provide a kind of novel crucible better addresses the above problem.
Utility model content
The purpose of this utility model is to provide a kind of making nitrogen more evenly and resisting the stronger trapezoidal graphite crucible of external force of producing for VN alloy.
The technical scheme that realizes the utility model object is: a kind of trapezoidal graphite crucible comprises graphite crucible body, described graphite crucible body is interior trapezoidal, trapezoidal graphite crucible bottom and trapezoidal graphite crucible bottom vertical, and trapezoidal graphite crucible wall top becomes angle α with trapezoidal graphite crucible wall bottom.
Preferably, to become angle α with trapezoidal graphite crucible wall bottom be 2 ° ~ 5 ° on trapezoidal graphite crucible wall top.
In VN alloy production process, the material between two trapezoidal graphite crucible spaces arranged side by side, in the situation that being subject to external force, because trapezoidal graphite crucible top is inclined-plane, can decompose the pressure of a part to graphite crucible body; The space on trapezoidal graphite crucible wall top is conducive to nitrogen and enters the inside of graphite crucible body, contributes to the production of VN alloy; The space on trapezoidal graphite crucible wall top is conducive to heat transmission.
The beneficial effects of the utility model: 1) the trapezoidal graphite crucible wall top of trapezoidal graphite crucible becomes angle with trapezoidal graphite crucible wall bottom, can realize material crucible is pressed to force resolution; 2) space on trapezoidal graphite crucible wall top is conducive to heat transmission; 3) increase flow of nitrogen gas space, improve the production technology of VN alloy; 4) improve the temperature of trapezoidal graphite crucible materials inside.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of trapezoidal graphite crucible of the utility model.
Wherein 1, graphite crucible body, 2, trapezoidal graphite crucible wall bottom, 3, trapezoidal graphite crucible wall top, α, angle.
Detailed description of the invention
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in more detail below.
Please refer to Fig. 1, the utility model comprises graphite crucible body 1, trapezoidal graphite crucible wall bottom 2, trapezoidal graphite crucible wall top 3; Graphite crucible body 1 is interior trapezoidal, trapezoidal graphite crucible bottom 2 and trapezoidal graphite crucible bottom vertical, and trapezoidal graphite crucible wall bottom 2 is 2 ° with 3 one-tenth, top of trapezoidal graphite crucible wall angle α.
Please refer to Fig. 1, in VN alloy production process, the material between two trapezoidal graphite crucible spaces arranged side by side, in the situation that being subject to external force, because trapezoidal graphite crucible top 3 is inclined-planes, can decompose the pressure of a part to graphite crucible body 1; The space on trapezoidal graphite crucible wall top 3 is conducive to nitrogen and enters the inside of graphite crucible body 1, contributes to the production of VN alloy; The space on trapezoidal graphite crucible wall top 3 is conducive to heat transmission.
By reference to the accompanying drawings the utility model is carried out to exemplary description above; obvious realization of the present utility model is not subject to the restrictions described above; as long as the various improvement that adopted technical solutions of the utility model to carry out; or without improving, design of the present utility model and technical scheme are applied to other occasions, all in protection domain of the present utility model.
