WZP-230NM series Wear resistant thermal resistance 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:
WZP-230NM series of wear-resistant thermal resistance is the working principle of two different components of the conductor ends by welding, forming a loop direct temperature measuring end called measuring end, the 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 thermoelectric thermal resistance values of the generated. Thermoelectric type assembly type WZP thermal resistance will increase as the temperature measuring end, thermoelectric sizeonly withthermocouple conductor material and the temperature difference between the two ends of the length, diameter and thermal electrode assembly without thermal resistance is mainly composed of a junction box, protection tube, insulation casing, terminals, power extremely basic structure. And with a variety of fixed device.
Three, application:
WZP-230NM series wear resistant thermal resistance by plasma spray technology, high chromium cast iron and high temperature alloy made of different materials wear protection tube, specifically for high, medium and low temperature resistant environment measurement design and manufacture, can be used in circulating fluidized bed, fluidized bed furnace, cement rotary kiln tail smoke chamber, pulverized coal furnace, ball mill and other industrial field.
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, 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 to use high temperature resistant casing, the most common moderate price, the use of temperature 800 to 1200 degrees.
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-resisting, wear-resisting layer thickness of 0.5 ~ 1.5mm, hard and tough, the smallest diameter up to 8 diameter, good surface quality, the use of 0 temperature 800 degrees centigrade. In the power plant coal mill in the life of 2 years.
