Specifications

1,Round Pizza Stone Dia381mm;
2,Color:Yellow/White;
3,Heat resistant;
4,Durable and Eco-friendly materials

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: How are the high alumina bricks fired?: Light and high alumina bricks are usually fired in a weak oxidizing atmosphere. In light and high alumina bricks firing, they are often rich in impurities such as R2O, RO, Fe2O3 and so on. They react with Al2O3 and SiO2 at high temperature to produce liquid phase. In the Al2O3 - SiO2 - R2O system, the growth rate of liquid phase increases with the increase of temperature at high temperature. So, because the increase of sintering temperature brings a lot of liquid phase, the decrease of liquid viscosity will lead to the deformation of brick and the decline of brick high temperature function. Therefore, the lower sintering temperature and longer holding time should be adopted in the sintering process dominated by liquid phase sintering. The production practice shows that the same firing temperature can be used for the high grade aluminum bricks. When fired in an inverted flame kiln, it is usually 1430 degrees centigrade and insulated by 40H. The high alumina bricks such as Ill are 1390~1420 degrees centigrade. When the tunnel kiln is fired, they are 1550 and 1450~1500 degrees centigrade respectively. High alumina brick is usually made of weak oxidizing atmosphere.

Q: What are the common thermal insulation materials for thermal conductivity?: The single organic insulation material should be the best polyurethane in the field. In accordance with the production process can be divided into on-site foam polyurethane and factory prefabricated rigid foam polyurethane board. The scene is polyurethane foam isocyanate and polyol to cool (polyether or polyester) two components as the main raw materials with additives, the on-site spraying construction with thermal insulation and waterproof function of the rigid foam material.

Q: How to make refractory bricks and boiler wall adhesion more firm?: If the condition, the user heat-resistant steel welding grip nails, expansion joints can not be too big.. Also to use high temperature aluminum brick, high temperature resistance, but also to extend its use cycle.

Q: Difference between low creep high alumina brick and ordinary high alumina brick: The emphasis is on the physical and chemical indexes of low creep and high alumina bricks. The physical and chemical indexes of the high alumina bricks are different, too. They are DRL-1550And LZ-75 perform GB GB/T2988-2012

Q: Can high alumina brick resist carburizing?: The key is to look at the content of Fe3O2 metal oxides (so-called anti carburizing brick generally refers to the content of Fe3O2 less than 1% clay brick and Gao Lvzhuan) just a photo shoot, out for everyone to see, high alumina brick common in reductive atmosphere has been chalking up.

Q: How to test the aluminium bricks of high alumina refractory bricks?: Before making bricks, the raw materials are usually tested and tested to see if the aluminum content is up to standard

Q: What is the apparent porosity of high alumina brick?: In the production of high alumina bricks in addition to the entity, there are many different sizes and shapes of different pores, pores can be divided into three categories: one side closed the other side and the outside world is called open pores, closed in the product not communicated with the outside is called closed pores, penetrating through pores called the few products.

Q: Which thermal shock stability of clay brick and high alumina brick is good?: High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.

Q: What are the lining structures of lime rotary kilns and what are the requirements for refractories?: The current configuration of domestic calcining active lime rotary kiln refractories are as follows: the discharge end of low cement high alumina castable with 3% steel fiber; the cooling zone and the firing zone: dry magnesia spinel brick with high aluminum brick with high temperature; preheating: high alumina brick; low temperature preheating zone: clay brick light clay brick; feeding end: low cement high alumina castable with 3% steel fiber; in addition, brick size also have the corresponding requirements; dimensional tolerances: dimensional tolerances used in different parts of the requirements are not the same, the general control in 2mm; corner damage: general permit edge damage 40mm and 5mm deep within angle loss in the hot and cold surface is allowed to have only one, three edges and the length of not more than 50mm; there are cracks parallel to the use of surface crack is not allowed, cracks of brick surface are allowed.

Q: The difference between clay bricks and clay bricks: Sintering bricks do not have clay bricks, so sintering bricks are made of stone. Clay brick is clay cooking, two yo, qualitative difference, but the appearance and color almost, but the quality is very different, life expectancy is also a great gap.
