Heat-resistant steel and firing of porcelain and ceramic products
Firing porcelain and ceramics is an activity that
leads to the creation of beautiful products with an interesting appearance and
shapes. Porcelain is considered a real art from today. Tableware decorated with
tables or ceramic ornaments amaze and arouse admiration. How is porcelain formed
and what is necessary for the whole process? About this below.
The process of porcelain formation
The creation and production of porcelain begins with
the design of a given product, and then the creation of a porcelain mass.
Always clean this mass, get rid of water and remove any air bubbles.
Then choose one production method, namely the choice
is:
•
casting
•
squeezing
•
turning
After choosing the production method and performing
specific activities in this area, you can go further, for firing. The process
of burning porcelain is very important, because it is the one that provides
durability and water tightness to each dish.
The importance of heat-resistant steel for the
ceramics industry
Burning porcelain is a process that is of great
importance for all products. Such an activity is possible due to the existence
of special firing furnaces or baskets. Such devices are made of solid materials
and their composition is dominated by heat-resistant steel. Some types of steel
such as 1.4835 are used to create
such machines on a very wide scale. This is due to their excellent properties
and ensuring the best firing effects. In general, porcelain firing always
occurs at very high temperatures, which is why a special furnace must be able
to withstand such working conditions. This means that it must be built of
durable and heat-resistant materials. Therefore, the use of heat-resistant
steel of the type 253MA or other is
very common and even indispensable. Such steels are also distinguished by their
resistance to the corrosive effect of the oxidizing atmosphere at very high
temperatures, which is why they form the basis of machines for firing ceramics.
What is the burning of porcelain and ceramics?
Ceramic ovens are used for firing porcelain and
ceramic products that we want to preserve. The whole firing process consists
primarily of drying ceramic or porcelain products at a minimum temperature of
800 degrees Celsius. Therefore, if we want to deal with the production of
products of this kind, we must necessarily look at a special oven that allows
to achieve such a high temperature. Such a device must be constructed of solid
elements based on heat-resistant steel - for example type MA253. Firing is usually divided into two processes. The first
firing is baking on a biscuit and this is the initial sacking of the product.
Later, after cleaning and sanding the biscuit, it can be covered with enamel
and then re-burned.
The object treated in this way is perfectly fixed.
Thanks to the high temperature that prevails in the furnace, ceramic or
porcelain products can be subjected to solid firing even for a few hours, which
gives them durability and a nice look. Porcelain created in this way is
delicate, but beautiful and worth possessing.
