WR series of wear-resistant thermocouple by plasma spray technology, high chromium cast iron and high temperature alloy made of different material wear protection tube, specifically for high, medium and low temperature resistant environment measurement occasions design and manufacture, suitable for circulating fluidized bed, boiling furnace, cement rotary kiln tail smoke chamber.
The wear-resistant thermocouple is provided with a wear-resistant head, a connecting rod, a screw thread or a flange, a junction box, a thermocouple core or a thermocouple wire which is used for mounting and fixing.
Because in different temperature range and the measured medium and the use of different high strength wear-resistant protective tube and surface modification, composite pipe type solid structure of this series of products applicable to the protection tube wear serious oil chemical, coal handling system, fluidized bed boiler, cement material cooked and refractory materials powder flow and material temperature measurement. To further improve the service life of thermocouple. Its performance is better than the existing wear-resistant thermocouple, won the user. Has a number of high-tech products in the international leading level, the special process of wear resistant materials under the premise of not affecting the temperature lag, completely solve the service life of the circulating fluidized bed boiler temperature thermocouple, casing protection has wear-resisting, resistance to high temperature oxidation, sulfidation resistance, resistant to liquid iron, limestone cement materials corrosion, anti erosion, anti vibration a lot of technologies, thermocouple life is generally one to two years.
The material can be divided into the following 3 categories, each of which has its own unique characteristics:
1, high temperature wear resistance alloy: according to the environmental characteristics of the high temperature wear, explosion-proof thermocouple specially designed pure alloy by vacuum smelting, special wear-resistant superalloy with high temperature oxidation resistance and high temperature strength, by forging the whole drilling. Processing defects less, high reliability, high temperature strength wear resistance comprehensive performance is good, the price is higher, the use of temperature 800 ~ 1200.
2, the composite wear-resistant alloy: the composite armor technology with abrasive particles to high temperature alloy, precision casting. Without turning, casing, high hardness, resistance to high temperature oxidation, magnetic level are a little casting defects but does not affect the high temperature wear resistance and sealing, is using the most common high temperature abrasion resistance sleeves, moderate price using temperature of 800 DEG C to 1200.
3, the ion diffusion of tungsten carbide: stainless steel as the matrix using ion implantation technology in the casing surface into tungsten carbide particles. With high hardness, high strength, high toughness, special wear-resisting, wear-resisting layer of a thickness of 0.5 ~ 1.5mm, hard, ductile, minimum diameter to Phi 8, good surface quality, use temperature of 0 to 800 DEG C, in the power plant grinding coal machine in the service life of up to 2 years.
