Strong convection structure box type furnace

Abstract

An air cooling experiment electric furnace comprises an electric furnace body installed in a convection chamber box body; a furnace body convection chamber is arranged between the electric furnace body and the convection chamber box body; the bottom of the convection chamber box body is provided with a bottom box body; the side of the bottom box body is provided with a fan; an air inlet chamber in the bottom box body is communicated with the furnace body convection chamber of the convection chamber box body; the electric furnace body is provided with a furnace door installed in a furnace door convection chamber housing; a furnace door convection chamber is arranged between the furnace door convection chamber housing and the furnace door; and the furnace door is connected with the furnace body convection chamber. A convection environment is formed around the electric furnace body to perform air blowing cooling for control system, thereby guaranteeing cold end accuracy and sensitivity of sensor. The air convection on the outer periphery of the furnace body can timely take away most heat; compared with natural cooling, the cooling time of the electric furnace is largely shortened.

Description

technical field [0001] The invention relates to the field of kilns, in particular to a box-type furnace with strong convection structure. Background technique [0002] The furnace temperature uniformity of the electric furnace is an important factor related to the quality of new materials and the effects of sintering, debinding, heat treatment, homogenization, etc., especially in the development of new lens materials, new ceramic debinding technology, and the manufacture of transparent conductive targets for TFT. At present, strict requirements are put forward for the uniformity of the furnace temperature. When the electric furnace commonly used is heated at present, the temperature and heat transfer of each part of the electric furnace are not the same, which seriously affects the uniformity of the furnace temperature. Therefore, a new type of structure is urgently needed. Electric furnace to solve the above defects. Contents of the invention [0003] The object of the p...
