Abstract

The utility model relates to a novel sagger, which comprises a bowl body. The sagger is characterized in that the bowl body comprises a carbofrax layer and an aluminum oxide layer, wherein the carbofrax layer and the aluminum oxide layer are pressed into a body, and the aluminum oxide layer is arranged on the outermost layer of the bowl body. The sagger has the advantages that first, the box body is pressed by the carbofrax layer and the aluminum oxide layer to lead the heat conductivity and the thermal shock resistance stability of a box body to be better, second, the temperature of the sagger is even, which can not be cracked and damaged through being repeatedly used, and the service span of the box body is led to be increased, third, the sagger saves production cost.

Description

A kind of novel saggar

[technical field]

The utility model relates to a kind of saggar that is used for loading in the Industrial Stoves calcined material.

[background technology]

At present, people make the saggar that nickel zinc magnetic core is adopted, and generally are to be made by resistant to elevated temperatures corundum-mullite or mullite-cordierite.During use nickel zinc magnetic core is loaded in the saggar, is placed in the pushed bat kiln then and fires.This saggar can have a strong impact on the electricity and the magnetic performance of magnetic core because of containing the SiO2 composition when firing.Therefore, people are place mat alumina wafer in saggar in use, with the bad reaction of avoiding magnetic core to cause with direct contact of saggar.

Yet find that in application in practice the alumina wafer of place mat very easily ftractures and damages in use, make the nickel zinc magnetic core performance of firing stable inadequately, shortened the service life of saggar, change alumina wafer continually and improved manufacturing cost especially.

Therefore, the utility model is done further to improve to saggar at the deficiencies in the prior art.

[utility model content]

The purpose of this utility model is at the deficiencies in the prior art, and a kind of long service life is provided, the novel saggar of stable performance.

For achieving the above object, the utility model by the following technical solutions:

A kind of novel saggar includes the alms bowl body, it is characterized in that described alms bowl body includes silicon carbide layer and alumina layer, and described silicon carbide layer and alumina layer are compressed to one, and described alumina layer is located at the outermost layer of alms bowl body.

Aforesaid a kind of novel saggar is characterized in that described alumina layer is made as one deck, and described alumina layer is arranged on the upper strata of silicon carbide layer.

Aforesaid a kind of novel saggar is characterized in that described alumina layer is made as two layers, and described silicon carbide layer is clipped between the upper and lower alumina layer.

The utility model adopts the advantage of such scheme to have: 1, the casket body is to be formed by silicon carbide layer and alumina layer compacting, makes the thermal conductivity of casket body and anti-thermal shock stability better; 2, temperature is even, uses the damage of can not ftractureing repeatedly, and increased the service life of saggar; 3, saved use cost.

Fig. 2 is A of the present utility model---the A cutaway view;

Fig. 3 is user mode figure of the present utility model.

[specific embodiment]

As shown in Figure 1, 2, a kind of novel saggar of the utility model indication, mainly be to be used for firing in the kiln nickel zinc magnetic core, it includes alms bowl body 1, described alms bowl body 1 includes silicon carbide layer 2 and alumina layer 3, described silicon carbide layer 2 is compressed to one with alumina layer 3, and described alumina layer 3 is located at the outermost layer of alms bowl body 1.Can put the magnetic core 4 that is used to fire on the described alumina layer 3, as shown in Figure 3.

Alumina layer 3 described in the utility model can only be made as one deck, and described alumina layer 3 is arranged on the upper strata of silicon carbide layer 1.Described alumina layer 3 can also be made as two layers, and described silicon carbide layer 2 is clipped between the upper and lower alumina layer 3.

The utility model is made as one with silicon carbide layer 2 and alumina layer 3 and constitutes the casket body, makes the casket body that higher rupture strength be arranged under the firing temperature of magnetic core, and has excellent thermal conductivity and anti-thermal shock stability.The interior temperature of saggar is evenly distributed, magnetic core is burnt till under consistent temperature, the magnetic core of having avoided bringing because of non-uniform temperature is out of shape defectives such as performance difference.Can make saggar bear frequent heating and cooling process, use the damage of not ftractureing repeatedly.Arranged long service life, saved use cost.
