A method for preserving long urban network with a long strip from the corrosive effects of urban network environment, including carburizing and nitriding catcher horseshoe chain, uniform surface layer of chromium oxide. But turning Horseshoe chain, a typical nitrogen-6% hydrogen atmosphere in a sintering furnace hot zone of operations, reduce environmental damage protection chromium oxide scales. Then it will be a lower temperature by re-oxidation, and then stored in the cooling zone further oxidation. Therefore, the long urban network with a reduction in cyclic oxidation furnace. It has been observed that the life, so that a long service life can be extended with a urban network, increasing the moisture content of typical nitrogen atmosphere sintering. The dew point of the atmosphere are heated zone furnace can increase the oxygen partial retention of chromium oxide scales on the belt surface. Appropriate adjustments to long urban network with a moisture content of no decarbonization parts are sintered. Given the environment described, it discusses the degradation of 314 stainless steel mesh belt is exposed to two nitrogen-based atmosphere sintering furnace: similar to a typical nitrogen-6% hydrogen mixture and modified the composition of the gas mixture. Modified atmosphere furnace set up using the newly developed cost-effective humidification system. The atmosphere is modified to maintain a protective chromium oxide on the surface of the entire belt sintering process and at the same time oxidation decarbonization of sintered parts. Ning 西卢 chain network Factory Horseshoe chain which is made of stainless steel slats made of special mold processing Horseshoe chain conveyor, and with it the use of stainless steel string winding shaft conveyor belt connected together. Article net long urban network which is linear toothed belt through the Horseshoe chain sprocket, has a stable operation and other characteristics. But for some users, they are not very understanding of the basic parameters define long urban network with, let's focus on a few to tell you about: 1, net wide: it refers to the long urban network with manifold degrees; 2 , wide: mainly refers to long urban network with a wide mesh back bend; 3, wear shaft diameter: Connecting the poles diameter mesh belt; 4, horizontal pitch: the representative of the two mesh back curved angular spacing; 5, longitudinal pitch: long urban network with mesh connection through the distance between the two axis distance of bars. Horseshoe chain conveyor _ 西卢 chain network Factory (certification) _ Pakistani Horseshoe chain by Ningjin 西卢 chain network plant.
