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.
The 4 generation of oxide film, high temperature, effectively prevent the oxidation corrosion of SO2 gas.

Six, according to the characteristics of wear casing is divided into the following categories:
1, wear resistant high temperature alloy high temperature wear: according to the characteristics of environment, using specially designed vacuum smelting of pure alloy, special wear-resistant high temperature alloy with high strength and high oxidation resistance at high temperature, the whole 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 to high temperature 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, tough, Zui small diameter up to 8, good surface quality, use temperature of 0~800 DEG C. In the power plant coal grinding machine used in the life of 2 years.

Seven, the use of:
1, NM series alloy steel wear-resistant thermocouple 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 wear-resistant thermocouple double the life.
