工业窑炉是用耐火材料砌成的用以煅烧物料或烧成制品的设备。它是一种能使产品完成一定温度曲线、气氛曲线、压力曲线耦合加工的设备。

工业窑炉主要用途
1、完成温度曲线要求
2、完成气氛曲线要求.
3、压力曲线要求，也可以把以上三点称为窑炉的三要素。
4、基本上各种形式的窑炉都是为了完成上面三要素的组合。

工业窑炉主要分类
1、按煅烧物料品种可分为：陶瓷窑、水泥窑、玻璃窑、搪瓷窑、石灰窑等；
2、前者按操作方法可分为：连续窑(隧道窑)、半连续窑和间歇窑；
3、按热原可分为：火焰窑和电热窑；
4、按热源面向坯体状况可分为明焰窑、隔焰窑和半隔焰窑；
5、按坯体运载工具可分为有窑车窑、推板窑、辊底窑(辊道窑)、输送带窑，步进梁式窑和气垫窑等；
6、按通道数目可分为单通道窑、双通道窑和多通道窑。

工业窑炉常识
1、一般大型窑炉燃料多为重油，轻柴油或煤气、天然气。
2、窑炉通常由窑室、燃烧设备、通风设备，输送设备等四部分组成。
3、电窑多半以电炉丝、硅碳棒或二硅化钼作为发热元件，其结构较为简单，操作方便，还有多种气氛窑等。
4、在具体行业，窑炉还有更多细分类型，如水泥回转窑、玻璃池窑、钢铁的高炉和转炉，化工行业的一些设备也可归为窑炉。但通常意义上的工业窑炉，范围主要指金属和无机材料的煅烧设备。
5、窑炉大致分为 箱式、井式、梭式、网带式、回转式、窑车式、推板式隧道电阻炉、真空炉、气体保护炉、超高温管式推板炉（碳管炉）、钨钼粉焙烧炉、还原炉等各种高、中、低温工业窑炉，工作温度200～2500℃。可用于ZnO压敏电阻器、避雷器阀片、结构陶瓷、纺织陶瓷、PTC&NTC热敏电阻器、电子陶瓷滤波器、片式电容、瓷介电容、厚膜电路、片式电阻、磁性材料、粉末冶金、电子粉体、稀土化工、聚焦电位器、陶瓷基板、高铝陶瓷及其金属化，触头材料、硬质合金材料、钨钼材料等的烧成。

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.
