Problems solved by technology

[0002] With the improvement of living standards, grilled food is delicious and more and more popular. The household food ovens produced in China are generally electric ovens. The inner shell and the outer shell of the oven are composed of inner and outer iron sheets. The interlayer is a heat insulation layer of refractory and thermal insulation materials, and an electric heater is installed in the box. Since this type of oven must be heated by electricity to be used, the practicability is greatly limited, and the structure of this type of electric oven is complex and costly. high
[0003] In addition, people are now more and more fond of having barbecues and dinners in the wild during holidays. Not only can they enjoy the beautiful scenery, but they can also enjoy delicious food with family and friends. However, there is no power supply in the wild, so electric ovens cannot be used. Electric ovens are gradually becoming popular. It has become a hot research direction for people. However, the materials used in the current non-electric ovens are either insufficient in fire resistance and high temperature resistance, or have uneven heat conduction and heating, which can easily cause food to burn, and burnt food not only makes food burnt The taste deteriorates, the nutrients are missing, and the burnt substances are easy to produce carcinogens. Long-term consumption of burnt and soot-contaminated foods will cause great danger to human health. Non-electric barbecue device has become a new demand

preparation example Construction

[0036] The preparation method of the refractory fiber is specifically:

[0037] The first step, crushing;

[0038] The second step, melting;

[0039] The third step is fiber formation;

[0040] The fourth step, collecting cotton;

[0041] The fifth step, acupuncture;

[0042] The sixth step is heat treatment.

[0043] The preparation method of the refractory fiber is further specifically:

[0044] In the first step, the above-mentioned raw materials are respectively crushed to form particles with a particle size of 50nm to 0.2mm;

[0045] The second step is to send the pulverized particles into the preheating furnace for preheating. The preheating temperature is 1350-1490°C for 4-6 hours. The preheated product is sent into the heating furnace for melting, and the melting temperature is 2000-2000°C. 2200°C, time 3-6 hours;

[0046] In the third step, the melted product is sent to the spinning machine to form fibers. The rotating speed of the spinning roller is 6000-12000...

Embodiment 1

[0070] The preparation of embodiment 1 refractory fiber

[0071] 650g of silicon dioxide (SiO 2 ), 270g calcium oxide (CaO), 50g magnesium oxide (MgO), 17g aluminum oxide (Al 2 o 3 ) and 13g zirconia (ZrO 2 ) were crushed into particles with a particle size of 0.1 mm, and the crushed particles were sent to a preheating furnace for preheating. The preheating temperature was 1400 ° C for 6 hours. The temperature is 2100°C, and the time is 6 hours. The melted product is sent to the spinning machine to form fibers. The rotating speed of the spinning roller is 12000 rpm, and the fiber length is 300pm. The fibers are collected and input into the cotton collector to obtain refractory fiber cotton. And accumulate to a certain thickness; the fifth step, the obtained refractory fiber cotton is subjected to single-side or double-side needling to form an acupuncture blanket, and the needle-punched blanket is subjected to heat treatment at a temperature of 900°C for 15 minutes to obtain...

Embodiment 2

[0072] The preparation of embodiment 2 refractory bricks

[0073] Shanxi Yangquan kaolin (produced by Yangquan Mingyang Kaolin Co., Ltd.) 670g, graphite 160g, chromium dioxide 90g, zirconium dioxide 80g are added in the mixer, while stirring and mixing, add 50g of water until the stirring is uniform, and the obtained The product is pressed into adobe in a 600-ton brick press to ensure that the density of the refractory brick is 3.4kg / m 3 , and then dried at 100°C for 24 hours to obtain shaped bricks, which were fired at 1600°C for 36 hours and then cooled to room temperature; then fired at 1800°C for 72 hours and then cooled to room temperature to obtain refractory bricks.
