Background

Silicon carbide rod is as indispensable material in the industry, along with the development of people's standard of living, also use more frequently to silicon carbide rod, and in the production of silicon carbide rod, especially in this process of heating silicon carbide rod, place it in firing equipment directly to heat usually, however old-fashioned heating furnace, when heating process to silicon carbide rod, because of being heated unevenly, lead to silicon carbide rod to appear the quality problem easily, consequently in order to improve production efficiency, improve the heating quality, and the security of workman's work, need a more stable convenient silicon carbide rod heating device urgently.

Disclosure of Invention

An object of the utility model is to provide a elema resistance heating furnace, this heating furnace simple structure, make simple installation, convenient to use are swift, and the during operation safety and stability more can effectual improvement workman's security of working, improves the stoving quality, has high use value.

The purpose of the utility model is realized like this: a silicon carbide rod resistance heating furnace comprises a box body, a heat conducting rod, fixing rings, an electric heating element and a base, wherein a top cover is arranged at the top of the box body, the fixing rings are arranged on the inner side surface of the top cover, a handle is arranged outside the top cover, and the top cover is connected with the box body through a hinge; the box bottom set up the base, the inside hollow structure that is of base, set up electric heating element in the hollow structure of base, electric heating element on set up power plug, the base on vertical direction set up the heat conduction stick, the heat conduction stick on install the elema, the heat conduction stick be connected with electric heating element, the top cap medial surface set up solid fixed ring for elema position department.

The side wall of the box body is internally provided with a heat insulation layer, and the material used by the heat insulation layer is silicon dioxide aerogel.

The inner diameter of the fixing ring is consistent with the outer diameter of the silicon carbide rod.

The side wall of the heat conducting rod is provided with a supporting column, and the supporting column is of a cylindrical structure.

The utility model discloses the beneficial effect who produces is:

1. the utility model discloses a elema is in the heating process, through the electric heating element heating, and heat conduction stick conveying heat, and the length of heat conduction stick is unanimous with the elema, so the elema is heated more evenly in the heating process, has avoided leading to the condition that quality problems appear in the elema because of being heated unevenly in the heating process.

2. The utility model discloses set up the thermal insulation layer in the heating furnace lateral wall, on the one hand can effectually store the heat in the box, improve heating efficiency, on the other hand workman also can not scalded by the lateral wall at the during operation, has improved the security of workman's work.
