Abstract
This invention relates to a zirconia ultra-temperature electric furnace hearth, comprising a main heating hearth (1) and an auxiliary heating hearth (2); the auxiliary heating hearth (2) is located at the outside of the main heating hearth (1); an auxiliary heating element (5) is mounted in the auxiliary heating hearth (2); a zirconia heating element (3) is mounted in the hearth at main heating area; positions for mounting the zirconia heating element (3) at the upper and lower parts of the hearth at main heating area are equipped with high temperature insulated material. This invention is the hearth made by utilizing the high temperature resistant characteristic of the zirconia heating element; the working temperature of the hearth at main heating area can be approached to more than 2000 DEG C; the combination of the insulated material with high temperature resistant characteristic and zirconia furnace wall can be utilized to form the mould forming; and the hearth is hard and reliable, which can be steadily used at the temperature of less than 2000 DEG C.
Description
Technical field
The present invention relates to the improvement of electric stove hearth, mainly relate to a kind of Zircite superhigh temperature electric stove hearth.
Background technology
At present, the zirconia heater has obtained application.But, in the application of superhigh temperature electric stove more than 1900 ℃, also do not popularize fully.At present, do not having most suitable refractory material more than 1900 ℃, the application of zirconia heater is restricted.
Summary of the invention
The purpose of this invention is to provide a kind of Zircite superhigh temperature electric stove hearth, make it have serviceability temperature height, strong, the robust characteristics of stability.
Purpose of the present invention can be achieved through the following technical solutions: it comprises main heating furnace and auxiliary oven thorax, the auxiliary oven thorax is positioned at the outside of main heating furnace, in the auxiliary oven thorax auxiliary heating element is set, in the main heating furnace zirconia heating element is set, the position that is used to install zirconia heating element in the upper and lower of main heating furnace is provided with high-temperature insulation material, make between zircite product and the zirconia heating element and form insulator, be used to insert the zirconia heater.
The furnace wall of described main heating furnace is a zircite product, and high-temperature insulation material is filled between furnace wall and the zirconia heating element.
Described high-temperature insulation material is an oxide dielectric material.
The present invention is the burner hearth that utilizes the resistant to elevated temperatures characteristic of zirconia heating element to make, and its main heating furnace operating temperature can reach more than 2000 ℃.High-temperature insulation material can utilize the mould moulding with combining of zircite product, makes burner hearth firm reliable, and is highly stable in use below 2000 ℃.
