Abstract
A porcelain grey tile without carburization and a sintering method thereof. Bauxite, purple sand, clay, and gas stove coal cinder are mixed, added with water to prepare a green body, and then the porcelain grey tile without carburization is sintered under a certain temperature condition. According to the invention, a mixture of multiple materials is used instead of pure clay for sintering, which saves clay resources; the green body does not crack when a lot of water is lost within a short period, which greatly shortens the drying time of the green body; during high temperature sintering, carbon particles are generated in raw coal reactions of generator gas and gas stove coal cinder, and colorize the inner and outer sides of the green body, which omits the colorization and color preservation processes in the prior art, shortens the process flow, increases the sintering efficiency, and saves energy.
Description
Technical field
The present invention relates to the firing field of material of construction, a kind of without carburizing porcelain grey tile and method for cooking thereof specifically.
Background technology
Grey tile is that clay is fired, be Steel Gray, give plain, sedate, simple and unsophisticated, quiet aesthetic feeling, become in recent years one of product that Designers recommends to the utmost, because firing temperature is higher, there is certain porcelain degree, there is the advantages such as High anti bending strength, wear-resistant, acid and alkali-resistance, life-span be long, therefore be referred to as porcelain grey tile.In prior art, firing of grey tile adopts following technique: clay dries in the shade in the cool after moulding, then after having fired in earth kiln, need to be through over carburizing, could cooling kiln discharge after protecting the techniques such as look, whole technique probably continues about two weeks, make production efficiency very low, and need during this period constantly to consume coal-fired, not only increase energy consumption, and coal combustion is insufficient causes exhaust gas emission to cause environmental pollution; , because grey tile adopts clay completely, fire meanwhile, caused the loss in a large amount of soils.
Summary of the invention
For solve the problems such as the resources such as clay fire coal are many, the firing time is long, production efficiency is low that need that exist in prior art when firing grey tile, the invention provides a kind of without carburizing porcelain grey tile and method for cooking thereof, shortened technical process, save the resources such as clay, fire coal, reduced the discharge of waste gas.
The present invention solves the problems of the technologies described above the technical scheme of employing to be: without carburizing porcelain grey tile, according to weight percent, raw material is by the bauxitic clay of 15-52%, the clay of the boccaro stone of 23-60%, 10-30% and the gas furnace cinder of 15-45% form, and the fineness of each constituent is 20-200 order;
This method for cooking without carburizing porcelain grey tile is to comprise the following steps:
Step 1, get bauxitic clay, boccaro stone, clay and gas furnace cinder and pulverize respectively or be milled to 20-200 order, and take each material according to aforementioned proportion, standby;
Step 2, the material that step 1 is taken are dry mixed and add the water of its gross weight 18-25%, make blank, then blank moulding is made to base substrate after then stirring, standby;
Step 3, the base substrate of making in step 2 is dried to 7-8h under the condition of 100-150 ℃, standby;
Step 4, the base substrate after drying in step 3 is sent in tunnel furnace and used oxydizing flame roasting, roasting process is as follows:
1) temperature-rise period
In tunnel furnace, the firing temperature of base substrate is risen to 900 ℃ in 8-10h, need during this period to supplement air and carry out to guarantee sufficient combustion;
2) high-temperature roasting
By the roasting 4-5h under the temperature condition of 900-1000 ℃ of the base substrate in tunnel furnace, during this period, in tunnel furnace, pass into producer gas;
3) process of cooling
Stop roasting and pass into producer gas, after naturally cooling 10-12h, complete without the firing of carburizing porcelain grey tile, open wicket and take out finished product.
In the present invention, described bauxitic clay does not limit the content of contained mineral substance, and the bauxitic clay that place of production produces arbitrarily all can be used;
Described boccaro stone also available iron ore waste residue replaces;
While firing grey tile in described clay and prior art, clay-phase used is same;
In described high-temperature calcination process, pass into producer gas, thereby its main purpose is for Formed is that grey tile is painted, so its usage quantity is without concrete restriction, producer gas add-on is large, and grey tile is painted darker, and the painted time is short, otherwise, painted shallow, need the time long.
In the present invention, in high-temperature roasting step, in tunnel furnace, pass into producer gas, owing to containing not clean-burning raw coal in gas furnace cinder, in this process, the lack of air in tunnel furnace, producer gas and the raw coal Formed particle that reacts, the surface that is attached to grey tile forms painted, and meanwhile, the carbon granule that the raw coal of grey tile inside generates makes grey tile inside also adhere to colouring.
Beneficial effect: the present invention compared with prior art has the following advantages:
1, the present invention adopts bauxitic clay, boccaro stone and gas furnace cinder to replace part of clay to fire grey tile, has not only saved clay resource, and makes waste obtain recycling as gas furnace cinder;
2, the present invention adopts multiple material to mix to have replaced pure clay and fires, a large amount of dehydrations can not cause the dry and cracked of base substrate yet at short notice, therefore, the base substrate that the clay of comparing is made must dry in the shade in the cool, base substrate of the present invention is dried and also can not cracked in the temperature below 200 ℃, has greatly shortened the time of drying of base substrate;
3,, in the high-temperature roasting stage, producer gas reacts with raw coal in gas furnace cinder that to produce carbon granules be extrinsic color in base substrate, has saved painted and color-protection technique of the prior art, has shortened technical process, has improved and has fired efficiency, has saved the energy;
4, adopt tunnel furnace to replace earth kiln to fire, improved utilization efficiency of heat energy, more easily accurately control firing temperature, shortened the firing time, improved quality product and yield rate.
