Abstract

The invention discloses a connected graphite crucible applied to producing vanadium-nitrogen alloy products. The connected graphite crucible comprises a crucible body and a push plate. The crucible body and the push plate are of an integrated structure, wherein the crucible body and the push plate are perpendicular to each other and are coaxially connected. A coaxial crucible cavity is formed in the crucible body, and a coaxial push plate cavity is formed in the push plate. The top of the crucible cavity is flush with the top of the crucible body, the bottom of the crucible cavity is communicated with the top of the push plate cavity, and the bottom of the push plate cavity is located between the bottom of the crucible body and the bottom of the push plate. Preferably, the crucible body, the crucible cavity, the push plate and the push plate cavity are all cuboids. Both the crucible body and the push plate are made of graphite. By the aid of the design, the uniformity of force-bearing points can be guaranteed when the push plate and the crucible body are stressed, the defects such as front-back arching caused by dislocation are overcome, and no gas layer separation exists in the connecting position of the crucible body and the push plate. Heat conduction efficiency is high, the service life is long, and batch manufacturing is easy.

Description

technical field [0001] The invention relates to a production tool for a tunnel pusher kiln, in particular to a conjoined graphite crucible used in the production of vanadium-nitrogen alloy products, which is particularly suitable for ensuring that the force points of the pusher plate and the crucible are uniform when the pusher plate and the crucible are stressed by an integrated structure. There is no air layer between the crucible and the push plate. Background technique [0002] The crucible used in the production of traditional tunnel pusher kiln adopts pusher plate and crucible split structure. In operation, the prior art has the following defects: [0003] First of all, when pushing, the split structure will cause the force point of the push plate and crucible to be uneven, causing problems such as misalignment and front and rear arching, which will damage the refractory material of the kiln body and cause blockage in the kiln, increasing the pressure of the push plat...
