Choose 4 of bone porcelain kiln

(3) fusible cone fusible cone under heating speed, has a fixed softening temperature. Commonly used to determine bone porcelain kiln in the degree of high temperature and uniform. 2 - general and adjacent Of three cone, a group for temperature measurement. Users can through the observation of the bending of pyrometric cone judgment can also be used for bone porcelain kiln stove temperature high temperature monitoring scene should be noted that pyrometric cone bending condition by heating speed, the influence of the atmosphere, its quality and Mosaic is bigger, when using, and judgment, should give full consideration to the impact of these factors. The pyrometric cone Mosaic and bend down. (4) WenHuan WenHuan measurement for high accuracy measurement of bone porcelain firing temperature indicator, used to record finished burning real bone porcelain firing process ( Including radiation and conduction heat) , and is suitable for discontinuous bone kilns or continuous roller kiln, shuttle bone bone kilns, bell kiln to bone, bone tunnel kilns, also applies to oxygen, nitrogen, air, vacuum and reductive firing atmosphere. Measuring WenHuan test temperature is lower than general pyrometric cone, should pay attention to when using. ( 2) Pressure measurement in the process of production, measurement and control of gas or liquid fuel and bone kilns in fluid pressure to ensure the normal operation of the kiln system has a very important role. Commonly used pressure gauges have fluid column pressure gauge and flexible type pressure gauge. Fluid column pressure gauge including u-shaped pressure gauge, sloping type pressure gauge, compensation declined pressure gauge, etc. Elastic pressure gauge including ordinary pressure gauge, electric contact pressure gauge, far eastone pressure gauge, etc. ( 3) Velocity of flow measurement of flow measuring method has two kinds of direct method and indirect method. Direct method available instrument or measure the flow rate and flow corresponding to the instantaneous value and the changes in volume. This kind of instrument with orifice flowmeter, rotor flowmeter, turbine flowmeter, etc. The indirect method is to use instrument to measure average velocity of fluid in pipe, and then multiplied by the fluid flows through the cross-sectional area of the conversion into the average flow rate value, this kind of instrument with pitot tube, anemometer, etc. , is commonly used bone porcelain kiln of flow velocity measurement instrument. ( 4) Flue gas flue gas analysis is a product of fuel analysis method, through the flue gas analysis, determination of content of each component in flue gas, so as to achieve the following purposes. (1) to identify bone kilns inner flame resistance, whether conform to the requirements of the firing technology. (2) identify the status of the fuel combustion is reasonable flue gas analysis instruments use sort is more, the commonly used with austenite gas analyzer, thermal conductivity type automatic analyzer, carbon monoxide, carbon dioxide analyzer, etc. Bone porcelain kiln the selection and design of bone porcelain kiln is the heart of bone China enterprise, bone China companies choose what kind of kiln for production, is essential. Choosing a kiln should pay attention to the following respects. ( 1) Production planning and process (1) bone bone China porcelain product variety and output ( Bone China) Production generally use shuttle kiln and small cross section tunnel kiln, choose what kind of kiln depends on bone porcelain product scale and diversity. (2) the manufacturing process of bone China, Bone China) , is generally high temperature burning, low temperature glaze to burn, so choose a good article is a high temperature element kiln glaze decorating firing kiln kiln, decorating firing kiln is according to the bone porcelain glair or bone porcelain glaze colors and also according to the bone China products, look to whether extensive use of saggar structure, etc. ( 2) Design and selection of bone porcelain kiln. (1) physical and chemical properties of bone China products. (2) the shape of the bone China products, thickness, size, mechanical strength and light transmittance, appearance, size requirements, etc. (3) the moisture content of bone China semi-finished products. (4) bone porcelain production. (5) are given. — Tangshan bone China mugs. 。 。 。 。 。
