Problems solved by technology

[0011] That is, because the fired product is located in the middle of the furnace, the fired product is separated from the multiple layered graphite heating elements arranged along the inner wall of the furnace by a certain distance, so it is difficult to directly receive the heat transferred by convection or radiation. The increase in the received heat decreases, resulting in uneven distribution of high temperature
[0012] In addition, there is a difference in temperature distribution on the fired product due to the heat that is not transferred uniformly from the center and edge of the furnace, and it is difficult to prevent specific changes in the fired product, resulting in poor firing

Abstract

The invention relates to a graphite heater furnace, in particular to a graphite heater furnace with multiple levels of graphite heating bodies of heating rods which are arranged in the horizontal direction inside a heating space part of a furnace body and capable of forming uniform temperature distribution on a burned object and improving the burning quality of the burned object. In order to realize the purpose, the graphite heater furnace comprises a housing, a furnace body which is arranged inside the housing and composted of an insulation body and graphite heating body which is arranged in a heating space part inside the furnace body and can produce heat, wherein the graphite heating bodies are horizontally arranged and distributed in multiple levels, the burned object is arranged on the heating rods in the heating space part inside the furnace body, and the outer periphery of the furnace body is provided with a cooling water trough.

Description

technical field [0001] The present invention relates to a graphite heater furnace, in particular to a heating body in which heating rods are arranged horizontally in multiple stages in the heating space of the furnace body, so as to form a uniform temperature distribution on the fired object, thereby improving the temperature of the fired object. Firing quality graphite heater furnace. Background technique [0002] Generally, Graphite Furnaces are used for sintering of LEDs, electrical components for electric vehicles, cathode materials, crystalline silicon semiconductor crystals for solar cells, ceramics as structural materials, and metal injection casting products. [0003] The graphite heater furnace is a kind of firing furnace, and such a graphite heater furnace is divided into a layered type (Batch Type) and a slot type (Tunnel Type) according to the structure. [0004] The trough-type graphite heater furnace is divided into a push type (Push type) and a roller type (R...
