根据耐磨套管的材质可以分为离子注渗碳化钨、耐磨高温合金、复合铸造耐磨合金3大类，下面介绍其各自独特的特点：1、离子注渗碳化钨：以不锈钢为基体采用离子注渗技术在套管表面注入碳化钨粒子。 Wear-resistant thermocouples can be divided into three categories: ion-implanted tungsten carbide, wear-resistant superalloys, and composite casting wear-resistant alloys according to the material of the wear-resistant sleeve. The following are their unique features: 1. Ion-carburization Tungsten: Tungsten carbide particles are implanted on the surface of the casing using ion implantation with stainless steel as the substrate. It has high hardness, high strength and high toughness, especially wear-resistant. The thickness of the wear-resistant layer is 0.5 ～ 1.5mm. The outer diameter is hard and tough. The minimum diameter can reach φ8. The surface quality is good. The operating temperature is 0 ～ 800 ℃. Service life is more than 2 years. 2. Wear-resistant high-temperature alloy: According to the characteristics of high-temperature wear environment, a specially-designed, pure alloyed, vacuum-smelted, wear-resistant high-temperature alloy with high-temperature oxidation resistance and high high-temperature strength is formed by forging and drilling. Less processing defects, high reliability, high temperature strength and wear-resistant thermocouples have good comprehensive performance and high price, and the use temperature is 800 ～ 1200 ℃. 3. Composite casting wear-resistant alloy: The composite armoring technology is used to add wear-resistant particles to the superalloy matrix, and it is precision melt-casting. No turning is required. The casing has high hardness and high temperature oxidation resistance. It has a few casting defects but does not affect high temperature abrasion resistance and sealing. It is the most common high temperature abrasion resistant casing. The price is moderate and the use temperature is 800 ～ 1200 ℃.
是电厂循环流化订锅炉,沸腾锅炉,粉磨煤机造气炉和水泥厂系列窑头,窑尾,炉头罩及化工,冶炼等高温耐磨环境较为理想的高技术类专用产品,G系列博采众长,采用独特的工艺配方,在失态平衡中制作出耐磨合金该产品与普通不锈钢金属,金属陶瓷保护管,与市场上同类耐磨合金保护管相比,其使用寿命提高1-5倍.由于环境温度差,温控点过高,振动较大,鼓风机风速过高,磨损严重,造成温度测量非常困难,使用寿命很短暂,一般的耐磨合金只有10-90天就磨透损坏,烧弯,折断,造成热电偶损坏,给用户带来很大的损失和不必要的麻烦,本公司生产的G系列弥补了这个缺G系列抗冲刷耐磨热电偶经过数百厂家,每年近万次的使用,反应很好,在很多场合具有领先同行的实力,完全可以同进口产品相媲美.耐磨热电偶具有抗振,耐磨,耐腐蚀,灵敏度高,稳定性好,准确性高,使用寿命 Abrasion-resistant thermocouples are high-tech types that are ideal for high-temperature and wear-resistant environments such as circulating fluidized boilers, boiling boilers, gasifiers for coal mills, and kiln heads, kiln tails, furnace head covers, and chemical and smelting in power plants. Dedicated product, G series draws many advantages and adopts unique process formula to make wear-resistant alloy in out of balance. This product is compared with ordinary stainless steel metal and cermet protection tube, and its service life is improved compared with similar wear-resistant alloy protection tube on the market. 1-5 times. Due to the difference in ambient temperature, the temperature control point is too high, the vibration is large, the blower wind speed is too high, and the wear is serious, which makes the temperature measurement very difficult and the service life is very short. The average wear-resistant alloy is only 10-90 days. Wear-through damage, burn-off, breakage, and damage to the thermocouples, bring great losses and unnecessary troubles to users.The G series produced by our company makes up for this lack of G series anti-scour wear-resistant thermocouples passed hundreds of manufacturers. It has been used nearly 10,000 times a year, and the response is very good. In many occasions, it has the strength of leading peers and can be comparable to imported products. The wear-resistant thermocouple has anti-vibration, wear resistance, corrosion resistance, high sensitivity, good stability, High accuracy and long life The advantages such as long length are currently the first choice for temperature measurement protection tubes in power plants, cement plants, chemical smelters and other high-temperature wear-resistant areas.
