Abstract
A kind of heat safe method of improvement enamel grate, the present invention provide a kind of heat safe method of improvement enamel grate, and the enamel grate to solve current manufacturing process manufacture is susceptible to burst porcelain or deformation is bad, and the present invention provides a kind of the following technical solution：The pre-heat treatment is carried out to blank grate before application of slip glaze.The beneficial effects of the present invention are：The intensity of grate is improved, the binding force of glaze and grate surface avoids bad generation of the grate in deformation and burst porcelain using process, and by improving, the tolerable temperature of grate rises to 450 DEG C by original 400 DEG C.
Description
Technical field
It is specifically a kind of promotion grate high temperature resistant that the present invention, which provides a kind of heat safe method of improvement enamel grate,
Production technology.
Background technology
Enamel grate is one of daily necessities, when use to its it is maximum require to be high temperature resistant, if not being resistant to height
Temperature may have burst porcelain or metaboly, seriously affect the use of enamel grate.
In the manufacturing process of former enamel grate, grate blank was manufactured using ground die cast technique before this, but ground molds
The defects of infiltration of technique molten iron is uneven and there are sand hole, few meat and fleshiness is made, painting glaze can be carried out after the completion of blank manufacture,
Then it is sintered using furnace cupola firing process, but furnace cupola firing process furnace temperature is not sufficiently stable, and blank is caused to absorb not
Uniformly, there are burst porcelain, coarse or blisterings etc. after the completion of enamel sintering.The enamel grate highest manufactured according to current manufacturing process
Tolerable temperature is 400 DEG C, due to various problems existing for blank pre-processing, causes to be susceptible to burst porcelain or deformation is bad.
Invention content
Mentioned above to solve the problems, such as, the present invention provides a kind of the following technical solution：
A kind of heat safe method of improvement enamel grate, the method are：Blank grate is carried out before application of slip glaze
The pre-heat treatment.When cast blank grate, if molten iron is unevenly distributed, there is that there are various defects such as stomatas etc. to lead
Cause blank grate intensity and surface roughness etc. it is not anticipated that it is good so that further influencing the grate processing in later stage and making
With such as applying that glaze is uneven, and when use is deformed, burst porcelain, in order to avoid these undesirable generations, inventor is by repeatedly examination
After testing, the pre-heat treatment this process is increased on the basis of existing technology, it is intended that will go out in blank manufacturing process
The defects of existing bubble, is eliminated, and to reach enhancing blank grate intensity, improves the effect of blank grate roughness, into one
The elimination of step applies the bad of glaze, and the deformation after finished product is made and burst porcelain is bad.
Preferably, the pre-heat treatment refers to preheating the blank grate at a temperature of 750 DEG C +/- 5 DEG C
10-20min is handled, the preferred the pre-heat treatment time is 15min.It finds that the temperature is more advantageous to after inventor's many experiments to disappear
The defect generated in defeathering biscuit furnace frame production process.
Further, grate is carried out after the pre-heat treatment applying glaze processing, without cooling grate, apply after glaze again at once into
Row sintering, sintering temperature are 740-760 DEG C, and preferred temperature is 750 DEG C, sintering time 50-70min, preferably when sintering
Between be 1h.Blank grate after the pre-heat treatment, when applying glaze and the combination on grate surface is more close.
Preferably, the sintering uses electric furnace firing process, electric furnace firing process to substitute original furnace cupola firing process, make
It obtains before enamel sintering is compared evenly, sintering process is stablized, and obtained product surface is smooth and glaze absorption is full.
Preferably, the blank uses machine die cast technique, and original ground die cast is substituted using machine die cast technique
Technique improves the hardness and surface roughness of grate, avoids the generation of some normal defect phenomenons.
The beneficial effects of the present invention are：The intensity of grate is improved, the binding force of glaze and grate surface avoids stove
Frame is in the bad generation of deformation and burst porcelain using process, and by improving, the tolerable temperature of grate is risen to by original 400 DEG C
450℃。
Specific implementation mode
This case is described further With reference to embodiment：
Embodiment 1
A kind of heat safe method of improvement enamel grate, this method are：Blank grate is manufactured using machine die cast technique, is completed
Afterwards, to blank grate carry out the pre-heat treatment, the pre-heat treatment refer to by the blank grate at a temperature of 745-755 DEG C
The pre-heat treatment 15min is carried out, blank grate is carried out without cooling grate, after the pre-heat treatment to apply glaze processing（Such as by blank stove
Frame is put into glazing in glaze hopper）, drying, then be sintered using electric furnace firing process, sintering temperature is 750 DEG C, sintering time
For 1h, after the completion of sintering, grate is obtained, grate can be obtained finished product using foot pad installation etc..To the skill using embodiment 1
Grate that art scheme obtains carries out high temperature resistant test, this batch of grate is tested by 450 DEG C of high temperature resistant.
Embodiment 2
A kind of heat safe method of improvement enamel grate, this method are：Blank grate is manufactured using machine die cast technique, is completed
Afterwards, to blank grate carry out the pre-heat treatment, the pre-heat treatment refer to by the blank grate at a temperature of 745-755 DEG C
The pre-heat treatment 20min is carried out, blank grate is carried out after the pre-heat treatment to apply glaze processing（Such as blank grate is put into glaze hopper
Glazing）, drying, then be sintered using electric furnace firing process, sintering temperature is 760 DEG C, and sintering time 70min has been sintered
Cheng Hou, has obtained grate, and grate can be obtained finished product using foot pad installation etc..To being obtained using the technical solution of embodiment 2
Grate carry out high temperature resistant test, this batch of grate is tested by 440 DEG C of high temperature resistant.
