工業(yè)窯爐
工業(yè)窯爐是用耐火材料砌成的用以煅燒物料或燒成制品的設(shè)備。它是一種能使產(chǎn)品完成一定溫度曲線、氣氛曲線、壓力曲線耦合加工的設(shè)備。
工業(yè)窯爐主要用途
1、完成溫度曲線要求
2、完成氣氛曲線要求.
3、壓力曲線要求,也可以把以上三點(diǎn)稱為窯爐的三要素。
4、基本上各種形式的窯爐都是為了完成上面三要素的組合。
工業(yè)窯爐主要分類
1、按煅燒物料品種可分為:陶瓷窯、水泥窯、玻璃窯、搪瓷窯、石灰窯等;
2、前者按操作方法可分為:連續(xù)窯(隧道窯)、半連續(xù)窯和間歇窯;
3、按熱原可分為:火焰窯和電熱窯;
4、按熱源面向坯體狀況可分為明焰窯、隔焰窯和半隔焰窯;
5、按坯體運(yùn)載工具可分為有窯車窯、推板窯、輥底窯(輥道窯)、輸送帶窯,步進(jìn)梁式窯和氣墊窯等;
6、按通道數(shù)目可分為單通道窯、雙通道窯和多通道窯。
工業(yè)窯爐常識(shí)
1、一般大型窯爐燃料多為重油,輕柴油或煤氣、天然氣。
2、窯爐通常由窯室、燃燒設(shè)備、通風(fēng)設(shè)備,輸送設(shè)備等四部分組成。
3、電窯多半以電爐絲、硅碳棒或二硅化鉬作為發(fā)熱元件,其結(jié)構(gòu)較為簡(jiǎn)單,操作方便,還有多種氣氛窯等。
4、在具體行業(yè),窯爐還有更多細(xì)分類型,如水泥回轉(zhuǎn)窯、玻璃池窯、鋼鐵的高爐和轉(zhuǎn)爐,化工行業(yè)的一些設(shè)備也可歸為窯爐。但通常意義上的工業(yè)窯爐,范圍主要指金屬和無(wú)機(jī)材料的煅燒設(shè)備。
5、窯爐大致分為 箱式、井式、梭式、網(wǎng)帶式、回轉(zhuǎn)式、窯車式、推板式隧道電阻爐、真空爐、氣體保護(hù)爐、超高溫管式推板爐(碳管爐)、鎢鉬粉焙燒爐、還原爐等各種高、中、低溫工業(yè)窯爐,工作溫度200~2500℃??捎糜赯nO壓敏電阻器、避雷器閥片、結(jié)構(gòu)陶瓷、紡織陶瓷、PTC&NTC熱敏電阻器、電子陶瓷濾波器、片式電容、瓷介電容、厚膜電路、片式電阻、磁性材料、粉末冶金、電子粉體、稀土化工、聚焦電位器、陶瓷基板、高鋁陶瓷及其金屬化,觸頭材料、硬質(zhì)合金材料、鎢鉬材料等的燒成。
Industrial kilns are devices made of refractory materials for calcining or firing articles. It is a device that enables the product to complete a certain temperature curve, atmosphere curve, pressure curve coupling processing.
Main use of industrial furnaces
1, complete the temperature curve requirements
2. Complete the atmosphere curve requirements.
3, the pressure curve requirements, you can also call the above three points the three elements of the furnace.
4, basically all forms of kiln are to complete the combination of the above three elements.
Main classification of industrial furnaces
1. According to the variety of calcined materials, it can be divided into: ceramic kiln, cement kiln, glass kiln, enamel kiln, lime kiln, etc.;
2. The former can be divided into: continuous kiln (tunnel kiln), semi-continuous kiln and intermittent kiln according to the operation method;
3, according to pyrogens can be divided into: flame kiln and electric kiln;
4. According to the condition of the heat source facing the blank body, it can be divided into Mingyan kiln, muffle kiln and semi-gas kiln;
5, according to the blank carrier can be divided into kiln car kiln, push plate kiln, roller bottom kiln (roller kiln), conveyor belt kiln, walking beam kiln and air cushion kiln;
6, according to the number of channels can be divided into single-channel kiln, dual-channel kiln and multi-channel kiln.
General knowledge of industrial furnaces
1. Generally, large-scale kiln fuels are mostly heavy oil, light diesel oil or gas and natural gas.
2. The kiln is usually composed of four parts: kiln room, combustion equipment, ventilation equipment and conveying equipment.
3. Most of the electric kiln is made of electric furnace wire, silicon carbon rod or molybdenum disilide as the heating element. The structure is simple, easy to operate, and there are many kinds of atmosphere kiln.
4. In specific industries, there are more subdivision types of kiln, such as cement rotary kiln, glass kiln, steel blast furnace and converter. Some equipment in the chemical industry can also be classified as kiln. However, industrial kilns in the usual sense mainly refer to calcining equipment for metal and inorganic materials.
5, kiln is roughly divided into box type, well type, shuttle type, mesh belt type, rotary type, kiln type, push plate type tunnel resistance furnace, vacuum furnace, gas protection furnace, ultra high temperature tube type push plate furnace (carbon tube) Furnace), tungsten-molybdenum powder roaster, reduction furnace and other high, medium and low temperature industrial furnaces, working temperature 200 ~ 2500 °C. Can be used for ZnO varistor, arrester valve, structural ceramic, textile ceramic, PTC&NTC thermistor, electronic ceramic filter, chip capacitor, ceramic capacitor, thick film circuit, chip resistor, magnetic material, powder metallurgy , electronic powder, rare earth chemical, focusing potentiometer, ceramic substrate, high alumina ceramic and its metallization, contact material, hard alloy material, tungsten molybdenum material, etc.

??????????????? In industrial furnaces, there are many valves in gas control and exhaust gas treatment, such as gas control solenoid valve, pneumatic switch ball valve, pneumatic internal thread ball valve, gas shut-off valve, electric single-seat control valve and pneumatic single seat adjustment. Use of the valve. Ventilation flue gas valves are used in exhaust gas treatment, such as electric ventilation butterfly valve, pneumatic ventilation butterfly valve, flapper valve, flue gas butterfly valve, flange butterfly valve, hard sealing butterfly valve and other control valves. ???????????????
