Circulating fluidized bed special wear-resistant thermocouple

Productoverview:
WRN-230NM series Robin Circulation fluidized bed special wear-resistant thermocouple Using special heat-resistant and wear-resistant alloy material as the outer protection tube and wear measuring head, installed in the Armored Core, not only has high on the fly ash particles erosion corrosion resistance, and the inner core body play a good protective effect under high temperature conditions. The connection form of flange or thread, long-term temperature measurement between 0 ~ 1200 DEG C, is the metallurgical industry using the temperature sensor in high temperature environment, wear very ideal.
Two, work principle:
WRN-230NM series Robin Circulation fluidized bed special wear-resistant thermocouple The electrode is composed of two different conductor materials. The working principle of two different components of the conductor ends by welding, forming a loop direct temperature measuring end call measurement end, terminal end call reference end. When there is temperature difference between the measuring terminal and a reference terminal, will produce thermal emf in the circuit, connected to display instrument, the instrument will indicate the corresponding temperature of the thermocouple electromotive force generated by the value of the. Thermoelectric type WRN thermocouple assembly will increase with the increase of temperature measurement terminal, thermoelectric sizeonly withthermocouple conductor material and the temperature difference between the two ends of the length, diameter and thermal electrode without thermocouple assembly is mainly composed of a junction box, protection tube, insulation casing, terminals, power extremely basic structure, and in a variety of fixed device.
Three, application:
WRN-230NM series Circulating fluidized bed special wear-resistant thermocouple Wear protective paint technology, high chromium cast iron and high temperature alloy made of different materials by plasma tubes, mainly used specially for high measurement environment, low temperature resistant design manufacture in various combustion temperature detection, boiler plant, curing high-temperature furnace, sintering furnace, forging furnace, energy recovery system, high temperature furnace, cement system slurry recycling high-temperature furnace, coal gasification system and high temperature equipment in the circulating fluidized bed.
Four, main features:
1, after the surface hardness of tungsten carbon alloy MVD to Rockwell HRC76 (about 1750 of Vivtorinox, ceramic grade) is 8 times the average hardness of stainless steel. Ordinary wear material hardness below HRC60.
2, the metal sheath creep point of 1850~2050 DEG C; high melting point: 2100 degrees, 1800 degrees below no bending deformation of high temperature combustion.
3, the surface of the alloy layer and the substrate to generate a whole stainless steel, so the thermal expansion coefficient and thermal resistance are exactly the same, there will be no cracking at high temperature.
Oxide film generated 4, high temperature, effectively prevent the oxidation corrosion of SO2 gas.
