High temperature resistance excellent insulating mullite kiln shelves

1. Description

When you decide to design a kiln, one should consider the kiln shelves an important factor that may influence the shape and size of the structure. Several factors will have a role in shelf selection.

Mullite Kiln shelf is one of the best kiln shelf in the kiln, its size will play a major role in the design of the kiln. There are several standard sizes of square and rectangular shaped shelves. The potter should choose a shelf size that is readily available. One should consider the size of ware, especially diameter, that is made and how the pots will occupy space on a shelf, including the placement of support posts. Maximum weight one can comfortably lift may be important when thinking about the type and size of the shelves.

After kiln shelf size is factored into the design of the kiln, then the type of shelf will be the next consideration. Maximum firing temperature, type of fuel and atmosphere, cost and again, shelf weight, all must be taken into account with shelf selection.

We must think about the thermal conductivity of the kiln shelves,This is explained as the coefficient of thermal conductivity, which is the amount of heat that passes through a unit cube of material in a given time when the difference in temperature difference across the cube is one degree. Simply put, different materials will conduct heat at different rates. The lower the number designation, the more insulating the material is and thus, more energy is required to heat the shelf to a given temperature. It takes considerably more time and energy to heat a cordierite than a silicon carbide shelf.Once heated, shelves with lower numbers will have a tendency to hold the heat longer, which may be an advantage in slowing the cooling of the kiln.

3. Features

Mullite kiln shelves can work at 1400℃,but commonly we do not make pure mullite, we often add some cordierite into mullite, then it is Cordierite-Mullite material, it has features of mullite and cordierite. Of course, we have our own formula, and we can recommend suitable for customer.

Sometimes we do not only consider using temperature,we also need to pay attention to load and using condition. If your temp-up and temp-down is very quick, then Cordierite is better.
