Productoverview:
WRN-430N series Wear-resisting Thermocouple The armored or armored core body temperature, with different materials and specifications of casing wear, abrasion resistance, shock resistance, good thermal shock resistance, several times the products in a variety of harsh occasions wear a high degree of the service life of up to ordinary products high, greatly improving the production efficiency, reduce the cost of consumption. 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, is the metallurgical industry using temperature sensor to wear the ideal environment.

Two, work principle:
WRN-430N series Wear-resisting Thermocouple The electrode is composed of two different conductor materials. When there is temperature difference between the measuring terminal end with the reference, will produce thermal potential, the instrument will display relevant thermal potential temperature.
The thermocouple electromotive force 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 with various fixed device.

Three, application:
WRN-430N series Wear-resisting Thermocouple After each year nearly ten times, the response was very good, with the strength of peers on many occasions, can be comparable with the imported products, the product has anti vibration, wear resistance, corrosion resistance, high sensitivity, good stability, high accuracy, long life etc.. Is the temperature measurement of power plant, cement plant, chemical smelting factory in the field of high temperature wear-resistant tube.

Four, main features:
1, according to the environmental characteristics of the wear resistant alloy, pure alloy by vacuum melting of specially designed, with special wear-resistant high temperature alloy high temperature oxidation resistance and high strength, the overall drilling and forging. Processing less defects, high reliability, high temperature strength and wear resistance performance is good, the price is higher, with a temperature of 800~1200 DEG C.
2, the composite wear-resistant alloy: the composite armor technology with abrasive particles in the matrix alloy, precision casting. Without turning, the casing of high hardness, high temperature oxidation, some casting defects but does not affect the high temperature wear resistance and sealing, is the use of high temperature wear casing, Zui ordinary moderate price, use temperature of 800~1200 DEG C.
3, ion osmosized tungsten carbide: stainless steel substrate by ion beam implantation of tungsten carbide particles in the casing surface infiltration technology. With high hardness, high strength and high toughness, special wear-resistant, wear-resistant layer thickness is 0.5 ~ 1.5mm, hard and tough, diameter up to 8, good surface quality, use temperature of 0~800 DEG C. In the power plant coal mill in the life of 2 years.

Five, technical parameters:

1, with the same type I thermocouple assembly, thermal resistance, a according to the ordering protocol;
2, non 1Cr18NI9Ti material wear protective tube part;
3, electrical outlet: M20 * 15, NPT1/2;
4, head wear hardness: HRC62-65;
5, protection grade: IP65;
6, every burst: D "BT4, D, CT5;
7, nominal pressure: 2.5MPa.
Six, media products:
1, strength:
NM alloy steel thermocouple protection tube is a new type of alloy materials in silicon, stomatal completely by silicon metal filling, the porosity is close to zero, high strength, corrosion resistance, abrasion resistance, oxidation resistance, long service life, the new material strength than general 3039H, 0Cr25Ni20 materials up to 5~10 times more.
2, excellent oxidation resistance:
The porosity is close to zero, the antioxidant properties of NM alloy steel is greatly improved, the high temperature service life can be extended by 3~10 times. This metal silicon carbide once heated to a high temperature, the surface of the natural formation of oxide thin protective film, this film even damage at high temperature will automatically make oxidation regeneration and healing, deterioration does not occur.
3, high heating efficiency: far infrared radiation NM metal silicon carbide rate is close to the perfect blackbody, for heat radiation components, will greatly improve the thermal efficiency of the unit.
4, excellent resistance:
General wear can not guarantee insulator, but NM metal silicon carbon material has good conductive properties, and has the function of static release, apply to the characteristics of multiple occasions.
5, high wear resistance:
NM alloy steel material hardness Hv > 27Gpa, in various media with extremely low wear rate and friction coefficient, and self lubrication, the material has excellent wear resistance under high temperature, special wear-resistant temperature measurement applications especially suitable for cement production line.
The corrosion resistance of 6, excellent: NM metal silicon carbide material has good corrosion resistance, corrosion resistant acid medium under various temperature conditions, corrosion in alkaline medium at room temperature.
Seventh, instructions for use:
1, NM series of alloy steel is mainly composed of a junction box, connecting pipe, special protection tube, insulation casing, casing, liner terminals, special thermode basic structure, and is equipped with various installation components, and optional integrated temperature transmitter in selected parts.
2, NM series alloy steel thermocouple protection tube wall thickness is 4~8 mm (average temperature is determined according to the place). The protective tube is designed for cement plant, its function is extended in C3, C4, C5, decomposing furnace, three wind pipe, smoke, kiln head temperature measuring points on the service life of the thermocouple.
3, the installation of the product, according to various industrial control points in different pre kiln blank or protection tube, and select the corresponding specifications of special thermocouple.
4, in the product design process, we have given full consideration to the 1000 to running the specifications and models to install the 10000T/D cement production line, production line for each control point for your use.
5, the length of the protection tube: furnace furnace wall thickness + insertion depth + = length of exposed part outside the furnace
6, in the production process, installation or replacement of the thermocouple, please slow into a furnace and thermocouple fixing and connecting device.
7, in the process of control point in the long-term temperature of 1100 DEG C, K type thermocouple work for about 60 days or so, at a high temperature state for a long time even silk, its accuracy will have small changes, temperature components can process requirements can be replaced.
8, related to the feeding or flushing places of use within 60 working days after the thermocouple, thermocouple 90 C flip re installed, the special double the life.
