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.

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.

Precautions when using 100w LED explosion-proof lamp
LED explosion-proof lighting is one of the potential markets for LED lighting industry. With the application of LED lighting technology in general outdoor venues, indoor home lighting has gradually matured. Taking the Japanese market, where the LED lighting market is taking off the fastest, as an example, many companies have seen high-level industrial LED explosion-proof lights. The most widely used is the 100w LED explosion -proof lamp. The 100W LED explosion-proof lamp is widely used in special working environments where electricity and dust are flammable and explosive, such as petrochemical, chemical, mining, semiconductor, shipbuilding, food, pharmaceutical factories, spray paint, etc. .
100w LED Explosion-proof lamp notes:
1. Regularly eliminate dust and dirt on the explosion-proof lamp housing to improve the light efficiency and heat dissipation performance of the lamp. The cleaning method can be based on the protection capability of the lamp housing, using water spray (over the shade on the lamp) or using a damp cloth. When cleaning with water spray, the power should be cut off. Never use a dry cloth to scrub the plastic housing (transparent part) of the lamp to prevent static electricity.
2. Check whether the transparent parts have been affected by foreign material, whether the protection network has loosened, stripped, and corroded. If so, use should be stopped and repaired and replaced in time.
3. The light source should be turned off in a timely manner to notify the light to be replaced, so as to avoid the ballast and other electrical components being in an abnormal state for a long period of time because the light source cannot be started.
4. If the accumulated water in the cavity of the lamp used in the humid environment should be cleared in time, replace the sealing parts to ensure the protective performance of the enclosure.
5. When you open the lamp cover, you should press the warning board to open the cover after turning off the power.
6. After opening the cover, check whether the flameproof joint surface is intact, whether the rubber seal is hardened or becomes sticky, whether the wire insulation layer is green and carbonized, and whether the insulation and electrical components are deformed and burned. If these problems are found, they should be promptly repaired and replaced.
7. Before applying the cover, apply a damp cloth (not excessively wet) to light the light and transparent parts of the light fixture to improve the light efficiency of the light fixture. A layer of 204-1 displacement rust preventive oil should be applied thinly on the flameproof joint surface. When the lid is closed, attention should be paid to whether the sealing ring plays a sealing role in the original position.
8. The sealed part of the lamp should not be frequently disassembled and opened. Patent zone road sealing technology; more in line with national explosion-proof new technology.
