High fever becomes temperature is the be out of shaping that influence product function does not appear when showing specific raw material amounts to this temperature in roast or other blemish. Basis of raw material of pottery and porcelain of avery kind of its are mineral of composition different, all existing a reasonable Gao Yun is made firing temperature or it is agglomeration limiting temperature. The purpose of roast is close to limiting temperature of this one agglomeration as far as possible namely and undertake below the circumstance that does not mar product performance, such ability get the product with agglomeration good pitch inside short time likely. So Gao Yun is made firing temperature is important roast craft parameter, also be qualitative to the bounds of firing temperature index.
Gao Yun is made firing temperature is to build agglomeration is fought to be out of shape in raw material the parameter on the fundamental of function, because of this Germany Ai Sen (ESSEN) tile institute puts forward to leave the loading in 0.5kg/cm2 generation 0.5% be out of shape the temperature of bate calls Gao Yun to make firing temperature (heat there is heat preservation time in the process) . Consequently Gao Yun is made firing temperature is out of shape by high temperature loading the experiment will decide. Flourish Cheng Naicai provides high quality fireproof data for you. The curve that high temperature loading is out of shape experiment earning arrives, combinative heat expands the curve can be decided truly firing of temperature roughly limits. High temperature loading is out of shape the experiment still can be judged give some kind of raw material to whether be planted at making some aptly the product of utility. Tell on universal, in roast from base substrate occurrence melt begins systole when, entered firing condition, right now temperature definition is begin firing temperature (tile is the product that belongs to microtherm part agglomeration, the definition that its begin firing temperature cannot be equal to be mixed at pottery and porcelain fireproof material) , as the heighten of temperature, systole increases ceaselessly; Be about to appear when systole the temperature when negative growth is eventually firing temperature. But the fluid photograph that agglomeration tile product produces in roast is measured eventually the requirement can be one fraction only, it is about 2% or lesser, because will appear in the fluid photograph of the excessive below high temperature,plasticity flows and cause below the load of base battlements be out of shape badly. Tell from other side, in agglomeration tile product the fluid photograph of excessive also won't bring the function of beautiful.
Because this is in production is actual in always be in afore-mentioned begin firing temperature and the Gao Yun that an appropriate temperature chooses to serve as specific raw material or product between firing temperature eventually to make firing of temperature or abbreviation for " firing temperature " . This also is mature the inhomogenous sex that the temperature inside base battlements and kiln distributings. Short time of flourish Cheng Naicai and have taller firing temperature and long but can achieve in the roast that undertakes below low temperature slightly identical firing quality. Though roast temperature is higher, the particle inside base substrate diffuses and agglomeration reaction is sharper, be needed firing time is less, but the existence of gradient often restricted the temperature inside the difference that distributings in the temperature inside kiln of large section channel and base substrate itself to use taller " firing temperature " (Gao Yun is made firing temperature) . Unoccupied place size of form, edge mixes battlements of the appearance that this also matters to a product, base pass hot mechanism to wait. And choose in furnace of contemporary fast roast kiln taller " firing temperature " (Gao Yun is made firing temperature) .
