Tungsten Carbide Roll Rings, also known as hard alloy roller ring, has been widely used in the rolling production of high-speed wire, bar, threaded steel, seamless steel pipes, etc. due to its good wear resistance, high-temperature hardness, heat fatigue resistance, thermal conductivity, and high strength.

What are the concerns of gas-fired thermal oil boiler piping anti-corrosion? Residual flux in the heating pipe of gas-fired oil-heating boiler can not be removed without leaving clean in the water system and cause corrosion. These rust areas are more abruptly exacerbated and corroded. A pinhole occurs in the heat sink, resulting in leakage. Some fluxes are rich in organic acids, and two or more metals together produce electrolytic corrosion. The most common materials used in heating systems are copper and stainless steel. Electrolytic corrosion occurs between iron and copper. In this case, steel will corrode faster than copper. When the gas boiler system is not well planned, such as when the heat pump is selected or the system is not well-closed and the system is closed, the negative pressure of the pump will bring outside air into the system. The oxygen in the air will accelerate the metal corrosion of the system. Under the neutral water quality, there will be excellent self-maintenance talents, but when the water quality is not good, there are many condensing household electric boiler heat exchangers using aluminum materials, because the appearance of aluminum is very simple to form a fine alumina maintenance film. This layer of oxide film is very slightly removed by the acid or alkaline water, resulting in corrosion. In addition, metal scraping of the heating system at the facility, cement residue from the bonded pipe, and some mineral oil, residual sand from the cast radiator, and microbes in the system can all contribute to the overall or partial corrosion of the system. In the heating system, localized areas such as heat exchange fins, cracks, etc., which are subjected to higher pressures, are more simply corroded. Contact phone, Manager Zhu
The Tungsten Carbide Roll Rings we produce mostly come in two series: WC Co and WC Co Ni Cr, with Co and Co Ni Cr as binders ranging from 6wt% to 30wt%. From a usage perspective, hard alloy rollers have good comprehensive mechanical properties, with a bending strength of over 2200 MPa and an impact toughness of (4-6) × At 10 ^ 6J/m ^ 2, the Rockwell hardness (HRA) can reach 78~90. During the high-speed wire rolling process, the single groove steel passing amount is much higher than that of cold hard cast iron or high-speed steel rollers.
Gas-fired oil-conducting oil boilers can be said to be indispensable in the course of their use. Gas-fired boiler piping systems are the necessary equipment for ensuring the normal supply of natural gas. It is necessary to pay attention to the corrosion prevention of gas-fired boiler pipes. After the gas boiler heating system pipeline is used for a long time, it will gradually appear different levels of gradual wear and degradation, gas boiler pipe anti-corrosion need to pay attention to what questions? Next Xiaobian to introduce you.
