on the spring instrument small make up with you a brief introduction of silicon carbide wear-resistant elbow applicable conditions and production process. Silicon carbide (SiC) wear-resistant elbow is also a kind of non-compound ceramics, but silicon carbide has a long history in the ceramic series, in recent years is an important refractory material, abrasive material heating body. This is a kind of use of SiC has excellent heat resistance, intensity, hardness, wear resistance, volume resistance parameters such as thermal state, machine, electrical characteristics of the material, the development of the industry has played a great role.

silicon carbide wear-resistant elbow is made of silicon carbide as the main raw material, through reasonable particle gradation, adding silicon powder, alumina powder and adhesive, etc., after pouring and molding, natural curing, drying, baking and other processes. It has excellent properties such as integral molding, no falling off, high hardness, good wear resistance, strong thermal stability and chemical corrosion resistance, especially insensitive to abrasive attack angle. As a lining material, the new composite silicon carbide can improve the wear resistance and corrosion resistance of the equipment. Its wear resistance is 3-5 times that of wear-resistant cast steel. Therefore, it is widely used in thermal power, coal, mining, metallurgy, cement, ports, Chemical industry and other fields. Scope of application of

silicon carbide elbow: conveying powder, block material, ash and other low-impact strong abrasive wear occasions working within 450 ℃ have high wear resistance and impact resistance. The use of steel pipe as the shell not only improves the mechanical properties and impact resistance of the pipe, but also facilitates installation and welding. The service life of this product is 3-5 times that of alloy cast steel pipes, generally up to 60000 hours or more, and has a high performance-price ratio.

Suzhou shang chun yi monitoring program-controlled equipment manufacturing co., ltd. supports the design, manufacture, debugging, service and supporting overall services of silicon carbide wear-resistant material accessories. it has built a 7200 ㎡ manufacturing base and more than 30 sets of high-precision processing equipment. the factory workshop has passed the ISO9001:2015 quality system certification, one-year warranty, solutions within 1 hour after sales, and free technical guidance.

What factors should be considered in the purchase of silicon carbide nozzles?


The quality and efficiency of the use of silicon carbide nozzles are also related to many factors, and the purchase of silicon carbide nozzles needs to consider the system conditions and operating conditions.

What are the factors that affect nozzle efficiency?


The traditional nozzle adopts the structure of cast steel, and the proper swing of the burner silicon carbide nozzle can change the position of the flame center to adjust the reheat steam temperature level; the dense and lean pulverized coal burner can prevent coking and high temperature corrosion in the furnace, and has the characteristics of stable ignition, good low load stability and low NOx emissions.

Comparison of Silicon Carbide Nozzle and Cast Steel Nozzle


The integral silicon carbide nozzle can effectively prevent fouling and slagging: when the boiler is fired with easy fouling and slagging coal, fouling, coking and slagging are easy to occur at the burner nozzle, thus affecting the combustion performance of the boiler. Because the conventional burner nozzle is made of cast steel, the material will deform in high temperature environment for a long time, resulting in uneven nozzle and eddy current;
