An overview of the

Due to different measured medium and different temperature range and high strength wear resistant protection tube and surface modification measures, constitute a multiple tube type materialization structure this series product is suitable for protecting tube wear serious petroleum chemical industry, coal conveying system, fluidized bed boiler, cement clinker and flowing powders and materials such as refractory temperature measurement. Further increase the service life of thermocouple. Its performance is superior to the current wear-resistant thermocouple, winning user praise. Has a number of high-tech products in the international leading level, its special process of wear resistant materials under the premise of without affecting temperature lag, completely solve the service life of the circulating fluidized bed boiler temperature measuring thermocouple, protect casing has wear-resisting, high temperature oxidation resistance, resistance to sulfide and liquid iron powder, limestone and so on concrete corrosion, scour resistance, resistance to vibration technology, makes the service life of the temperature measuring thermocouple generally one to two years.

The characteristics of

According to the materials of wear-resistant casing, it can be divided into the following three categories, and each type has its own unique characteristics:

1. Wear-resistant high-temperature alloy: according to the characteristics of high-temperature wear environment, the pure alloying alloy specially designed by the explosion-proof thermocouple adopts vacuum smelting and has anti-high-temperature oxidation

And the high - temperature strength of the special wear - resistant high - temperature alloy, forged by the overall drilling. Processing less defect and high reliability, high temperature strength wear-resisting comprehensive performance is good, price is higher, temperature 800 ~ 1200 ℃.

2. Composite casting wear resistant alloy: the composite armored technology is used to add wear resistant particles to the matrix of high-temperature alloy, and precision casting is formed. No turning is required

Work, casing high hardness, resistance to high temperature oxidation, magnetic level gauge with a little turning casting defects but not influence the high temperature wear resistance and sealing, is the most common use of high temperature resistant casing, price moderate, temperature 800 ~ 1200 ℃.

3. Ion-injected tungsten carbide: the tungsten carbide particles are injected into the casing surface by ion-injected technology using stainless steel as the matrix. Hard, high strength, high Gao Ren, special wear-resisting, wear-resisting layer thickness 0.5 ~ 1.5 mm, rigid toughening, minimum diameter to phi 8, good surface quality, use temperature 0 ~ 800 ℃, the service life of the coal mill in power plant for more than 2 years.
