Abstract
The invention relates to a sintering process of a ceramic piece, in particular to a free-fall sintering process of the ceramic piece. The invention adopts the following technical scheme: a free-fall sintering process for ceramic parts is characterized in that a blank is formed, the formed blank is subjected to early firing, the early firing is carried out until the blank is formed and shaped, then the shaped blank enters a forming combustion channel in a free-fall mode, the temperature in the forming combustion channel is over 1000 ℃, the shaped blank passes through the forming combustion channel to form a ceramic part finished product, high-temperature liquid is arranged below the combustion channel, and the ceramic part finished product falling from the combustion channel falls into the high-temperature liquid to be rapidly cooled. By adopting the scheme. The invention overcomes the problems in the prior art and provides a novel free-fall sintering process of a ceramic piece, which has low cost and high speed.
Description
Technical Field
The invention relates to a sintering process of a ceramic piece, in particular to a free-fall sintering process of the ceramic piece.
Background
The ceramic is widely applied to various fields because the outer surface of the ceramic has the advantages of good smoothness, compactness and the like, the existing ceramic manufacturing process is to put the ceramic into a sagger which is a container for roasting the ceramic and is made of refractory materials, and the function of the existing ceramic manufacturing process is to prevent the direct contact of a ceramic blank and kiln fire and avoid pollution and contact. The kiln burning time is long, and the temperature is over 1000 ℃. The disadvantages of this method are that the burning temperature needs to be very high and the burning time is long, because the ceramic piece needs the saggar to fix and place, the temperature conduction is slow, and in addition, the problem of slow heat dissipation also exists when cooling.
Disclosure of Invention
The invention overcomes the problems in the prior art and provides a novel free-fall sintering process for ceramic parts, which has low cost and high speed.
The invention adopts the following technical scheme: a free-fall sintering process for ceramic parts is characterized in that a blank is formed, the formed blank is subjected to early firing, the early firing is carried out until the blank is formed, then the formed blank enters a formed vertical combustion channel in a free-fall mode, the temperature in the formed vertical combustion channel is as high as the sintering temperature of the ceramic parts, the formed blank passes through the formed vertical combustion channel to form a finished ceramic part product, high-temperature liquid is arranged below the formed vertical combustion channel, and the finished ceramic parts falling from the formed vertical combustion channel fall into the high-temperature liquid to be rapidly cooled so as to realize tempering.
The invention further provides that: the pre-firing to the blank shaping refers to the state that the blank is fixed in shape before becoming the finished ceramic piece.
The invention further provides that: the temperature of the high-temperature liquid is the tempering temperature of the ceramic piece.
Through adopting above-mentioned scheme, can make the stock design back form the ceramic article fast through shaping burning channel, its is very fast, and do not need the saggar, save the cost greatly, in addition its whereabouts speed receives the influence of air current in the shaping burning channel when passing through shaping burning channel after the stock design, speed is controllable, the burning is more comprehensive, and the process is contactless, the ceramic article can not warp, the yield is very high, in addition sintering temperature in the first step will be looked the difference of raw materials and service function and change, high temperature liquid also is so.
Detailed Description
The technical solution of the present invention is further illustrated by the following specific examples.
A free-fall sintering process for ceramic parts comprises the steps of firstly forming blanks, conducting pre-firing on the formed blanks to be formed, enabling the temperature to change according to different raw materials and different using functions, enabling the formed blanks to enter a forming vertical combustion channel in a free-fall mode, enabling the temperature in the forming vertical combustion channel to be based on the sintering temperature of the ceramic parts, enabling the formed blanks to pass through the forming vertical combustion channel to form ceramic part finished products, placing high-temperature liquid in the forming vertical combustion channel, enabling the ceramic part finished products falling from the combustion channel to fall into the high-temperature liquid to be rapidly cooled, achieving tempering, and finally taking out the ceramic parts, wherein the finished products meet requirements.
