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 specifically no carburizing porcelain grey tile and method for cooking thereof.
Background technology
Grey tile is that clay is fired, and is Steel Gray, gives plain; Sedate, simple and unsophisticated, quiet aesthetic feeling; Become one of product that the tDesigners recommends to the utmost in recent years,, have certain porcelain degree because firing temperature is higher; Have advantages such as folding strength height, wear-resistant, acid and alkali-resistance, life-span be long, so be referred to as the porcelain grey tile.Firing of grey tile adopted following technology in the prior art: clay dries in the shade through after the moulding in the cool; After in earth kiln, firing completion then, need after technologies such as over carburizing, guarantor's look, could cool off kiln discharge, whole technology probably continues about two weeks; Make production efficiency very low; And need constantly to consume coal-fired during this period, not only increase energy consumption, and coal combustion is insufficient causes exhaust gas emission to cause environmental pollution; Simultaneously, because grey tile adopts clay to fire fully, caused the loss in a large amount of soils.
Summary of the invention
For solving the problems such as resource such as clay fire coal is many, the firing time is long, production efficiency is low that need that when firing grey tile, exist in the prior art; The invention provides a kind of no carburizing porcelain grey tile and method for cooking thereof; Shortened technical process; Practice thrift resources such as clay, fire coal, reduced exhaust gas discharging.
The present invention solves the problems of the technologies described above the technical scheme of employing to be: no carburizing porcelain grey tile; According to weight percent; Raw material is made up of the bauxitic clay of 15-52%, the boccaro stone of 23-60%, the clay of 10-30% and the gas furnace cinder of 15-45%, and the fineness of each constituent is the 20-200 order;
The method for cooking of this no carburizing porcelain grey tile is may further comprise the steps:
Step 1, get bauxitic clay, boccaro stone, clay and gas furnace cinder pulverize separately or ball milling, and take by weighing each material according to aforementioned proportion to the 20-200 order, subsequent use;
Step 2, the material that step 1 is taken by weighing are done the water that mixes and add its gross weight 18-25%, make blank after stirring then, again base substrate are processed in the blank moulding, and be subsequent use;
Step 3, the base substrate of processing in the step 2 is dried 7-8h under 100-150 ℃ condition, subsequent use;
Step 4, the base substrate after the oven dry in the step 3 is sent into and used the oxydizing flame roasting in the tunnel, roasting process is following:
1) temperature-rise period
Firing temperature with base substrate in tunnel rises to 900 ℃ in 8-10h, need replenish air during this period and carry out to guarantee sufficient combustion;
2) high-temperature roasting
With the roasting 4-5h under 900-1000 ℃ temperature condition of the base substrate in the tunnel, during this period, in tunnel, feed producer gas;
3) process of cooling
Stop roasting and feed producer gas, promptly accomplish firing of no carburizing porcelain grey tile behind the naturally cooling 10-12h, open wicket taking-up finished product and get final product.
Among the present invention, described bauxitic clay does not limit the content of contained mineral substance, and the bauxitic clay that promptly any place of production produces all can use;
The also available iron ore waste residue of said boccaro stone replaces;
Used clay is identical when firing grey tile in said clay and the prior art;
Feed producer gas in the said high-temperature calcination process, thereby its main purpose is painted for grey tile in order to generate carbon, so its usage quantity there is not concrete qualification; The producer gas add-on is big, and grey tile is painted darker, and the painted time is short; Otherwise, then painted shallow, need the time long.
Among the present invention, in the high-temperature roasting step, in tunnel, feed producer gas; Since contain not clean-burning raw coal in the gas furnace cinder, in this process, the lack of air in the tunnel; Producer gas and the raw coal generation carbon granule that reacts; Form paintedly attached to the surface of grey tile, simultaneously, the carbon granule that the inner raw coal of grey tile 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 instead of part clay to fire grey tile, has not only practiced thrift clay resource, and makes that waste such as gas furnace cinder have obtained utilizing again;
2, the present invention adopts multiple material mixing to replace pure clay to fire; A large amount of at short notice dehydrations can not cause the dry and cracked of base substrate yet; Therefore; The base substrate that the clay of comparing is processed must dry in the shade in the cool, and base substrate of the present invention is dried in the temperature below 200 ℃ and also can not cracked, and has shortened the time of drying of base substrate greatly;
3, in the high-temperature roasting stage, it is extrinsic color in the base substrate that the raw coal reaction in producer gas and the gas furnace cinder produces carbon granules, has saved painted and color-protection technique of the prior art, has shortened technical process, has improved and has fired efficient, has saved the energy;
4, adopt tunnel to replace earth kiln to fire, improved utilization efficiency of heat energy, accurately control firing temperature more easily, shortened the firing time, improved quality product and yield rate.
