Knowledge about high temperature wear-resistant thermocouples
2011-9-7 9:00:29

     不同可以分为耐磨高温合金,离子注渗碳化钨,复合铸造耐磨合金三种 ,并且每一 都有其各自独特的特点 ,以下是三类不同的分析: According to the material of the wear-resistant sleeve, it can be divided into three types: wear-resistant high-temperature alloy, ion implanted tungsten carbide, and composite casting wear-resistant alloy . Each has its own unique characteristics . The following are three different types of analysis. :
特点,专门设计的纯合金化的 ,并且 采用真空冶炼的,具有抗高温氧化和极高的高温强度的专用耐磨高温合金, 经锻造整体钻孔而成 1. Wear-resistant high-temperature alloy: According to the characteristics of high-temperature wear environment , a specially designed pure alloyed and vacuum smelted, special wear-resistant high-temperature alloy with high temperature oxidation resistance and high high temperature strength, is a forged overall drill Made of holes . 加工缺陷少,可靠性高,高温强度耐磨综合性能好, 因此 价格 较高 Due to less processing defects, high reliability, good high temperature strength and wear resistance, the price is relatively high . 使用温度 800~1200℃。 The general use temperature is 800 ~ 1200 ℃.

、离子注渗碳化钨: 以不锈钢为基体 在套管表面采用离子注渗技术注入碳化钨粒子。 2. Ion implantation of tungsten carbide: Based on stainless steel , the tungsten carbide particles are implanted on the surface of the casing by ion implantation. 具有高硬、高强、高韧,特别耐磨,耐磨层厚度 达到 0.5~1.5mm,外硬内韧,最小直径 φ8,表面质量好 It has the following advantages: it has high hardness, high strength, high toughness, and is particularly wear-resistant. The thickness of the wear-resistant layer reaches 0.5 to 1.5 mm, the outer hard and inner toughness, the minimum diameter is φ8, and the surface quality is good . 使用温度 0~800℃,在电厂磨煤机中使用寿命达2年以上。 The general use temperature is 0 ~ 800 ℃, and the service life of the coal mill in the power plant is more than 2 years.

、复合铸造耐磨合金:采用复合铠装技术 以高温合金基体加入耐磨粒子,精密熔铸成型。 3 , composite casting wear-resistant alloy: using composite armoring technology , wear-resistant particles are added to the superalloy matrix, precision melting casting. 不需 车削加工,套管硬度高,抗高温氧化 Features are: no turning is required , high casing hardness and high temperature oxidation resistance . 有少许 铸造缺陷但 不影响高温耐磨和密封性,是使用 最普通的高温耐磨套管 Although there are a few casting defects, it does not affect high temperature wear resistance and sealability. It is the most common high temperature wear resistant sleeve used . 也比较 适中, 一般 使用温度 800~1200℃。 The price is also relatively moderate, and the general use temperature is 800 ~ 1200 ° C.
