1,Square Heat Resistant Pizza Stone 13inch;
2,Color:Yellow;
3,Heat resistant;
4,Durable and Eco-friendly material

Our qualified pizza stones are made of cordierite, which is eco-friendly and free of heavy metals, cadmium, lead as well as other harmful substance.

It can be used in either conventional oven,microwave oven,or directly on the fire.It's working temperature is 1000°c and it would not crack no matter how extremely change of the temperature.

It helps to distribute the heat of the oven evenly to your pizza and absorb excess moisture creating a crisper crust.By the way,it's not only ideal for baking pizza but also foccacia,french bread,croissants,cookies,biscuits,and more,just use your imagination

Q: Introduction of high alumina brick: High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3. If the content of Al2O3 is higher than 90%, it is called corundum brick. Because of the different resources, the standards of different countries are not identical. For example, European countries limit the content of Al2O3 to high alumina refractories by 42%. In China, the content of Al2O3 in high alumina brick is usually divided into three parts: I, etc. - Al2O3 content, >75%, II, etc. - Al2O3 content is 60 ~ 75%, and the content of Al2O3 is 48 ~ 60%.

Q: What is the difference between corundum and high alumina??: The difference between them lies in the content of alumina and the alumina refractory products with alumina content higher than 48%The content of Al2O3 is higher than 90%, which is called corundum brick.

Q: Application characteristics of high alumina brick: Thermal shock stability. In high alumina brick products, the stress concentration is due to differential expansion when the temperature of refractory brick changes. Therefore, the high aluminum brick products than clay brick products thermal shock stability is poor, general water temperature only 3 - 5 times.

Q: What is the standard size of high alumina brick?: Standard brick: 230 x 115 x 65; four points: 230 x 115 x 40; three points: 230 x 115 x 30; 150 x 120: Brick gable. Light weight brick 1 to 1.7 kilograms; heavy clay superscript brick weighs 3.75 kilograms; light 30 plates 0.79 kilograms; light 40 plates, 1.05 kilograms.

Q: How to make refractory bricks and boiler wall adhesion more firm?: Suggest that you use fire brick to increase the length of brick or pull the amount of turn, and use high temperature mortar masonry

Q: Are there any differences between insulating bricks and refractory bricks?: As the name suggests, the main role of insulating brick is used to preserve heat and reduce the loss of heat. Such as: Molai S; and the firebrick is mainly used to withstand flame burn. Bricks usually do not contact fire directly, while refractory bricks usually contact the flame directly.

Q: What are the requirements for refractory materials in heat treatment furnace?: The structural strength of high temperature is evaluated by loading softening point. Load softening point is that under certain pressure (2 kg/ cm 2 = 0.2MPa) under the condition of heating rate to heating, measured the sample deformation (deformation for the original sample 0.6%) temperature. This temperature is called the softening point of the refractory. Sample size is Phi 36 x 50mm.

Q: Use of high alumina refractory bricks?: High alumina refractory brick in Al2O3 more, close to neutral refractory material, can resist acid slag and alkaline slag erosion, because it contains SiO2, so alkaline slag ability than acid resistance slag ability less.It is widely used in building blast furnace, hot blast furnace, furnace top, blast furnace, reverberatory furnace and rotary kiln lining. In addition, high alumina bricks are widely used as furnace regenerative checker, pouring system for plug nozzle, etc..

Q: How does the physicochemical index change when the high alumina brick is used at high temperature?: When the high alumina brick is used at high temperature, the physical and chemical indexes and other constants will not change if the temperature is in the physical and chemical indexes and the softening temperature of the load.

Q: How can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?: Because the hot air outlet of the top burning hot blast furnace is high, the installation requirement of the hot air manifold is high, and the requirement of the strength of the pillar structure is higher, so the rectangular arrangement of the hot blast stove is arranged. The top burning hot blast stove is located on the furnace top because of burner and hot air valve,Therefore, operation, maintenance and installation all require mechanization and automation. Also, because these water cooled valves are mounted with a high elevation,Therefore, the demand for cooling water supply pressure should be improved accordingly, the use of large top burning hot blast stove, the key lies in the design of high-power high-efficiency short flame burner. The top combustion hot blast furnace absorbs the advantages of internal combustion and external combustion hot blast stoves, and overcomes some of their shortcomings,Its structure can meet the requirements of modern blast furnace for high temperature, high pressure and large scale development,Combustion capacity, while meeting production requirements, has been successfully reduced by many devices,
