复合雨水篦子模具

复合雨水篦子模具韧性好。冲击值与中碳钢材详尽,是灰铁材料的10倍以上。抗腐蚀性强。喷水腐蚀试验,九十天的腐蚀量仅为钢管的1/40,是灰铁管的1/10。使用寿命是灰铁管的2倍,是普通钢管的5倍。塑性好。延伸率≥7%,与高碳钢材相近,而灰铁材料延伸率为零。强度高。抗拉强度ób≥420MPa,屈服强度ós≥300MPa,与低碳钢材相同,是灰铁材料的三倍。由于球墨铸铁的球状石墨微观结构,在减弱振动能力方面,球墨铸铁优于铸钢,因此更加有利于降低应力。选择球墨铸铁的一个重要的原因在于球墨铸铁比铸钢成本低。球墨铸铁的低成本使得这种材料更加受欢迎,铸造效率更高,也较少了球墨铸铁的机加工成本。预制井盖模具,复合雨水篦子模具主要是用来生成水泥井盖使用的,水泥井盖主要用于封闭通往地下各种设施如：自来水、污水、电缆、天然气、消防管道、环卫等的一个封闭物,也可以称之为地下门。以前城市道路由于交通、承载压力大的原因主要使用金属井盖,但是一些不法分子却把这防止人们日常出行受阻的金属井盖当成了金钱,进行盗窃进而转手卖废铁。因此人们行走掉入污水井、车辆前胎进入自来水井的事件常有发生。复合雨水篦子模具   井篦子模具  雨水篦子模具The compound rain grate mould has good toughness. Impact value and medium carbon steel are detailed, more than 10 times of gray iron material. Strong corrosion resistance. In the water spray corrosion test, the corrosion amount in 90 days is only 1 / 40 of the steel pipe and 1 / 10 of the gray iron pipe. Its service life is twice that of grey iron pipe and five times that of ordinary steel pipe. Good plasticity. Elongation ≥ 7%, similar to that of high carbon steel, while the elongation of gray iron material is zero. High strength. The tensile strength is not less than 420MPa, and the yield strength is not less than 300mpa. Due to the microstructure of spheroidal graphite, spheroidal graphite cast iron is better than cast steel in reducing vibration capacity, so it is more conducive to reducing stress. One of the important reasons for choosing nodular cast iron is that the cost of nodular cast iron is lower than that of cast steel. The low cost of nodular cast iron makes this material more popular, with higher casting efficiency and less machining cost of nodular cast iron. The prefabricated well cover mold and the composite rainwater grate mold are mainly used to generate the cement well cover. The cement well cover is mainly used to seal a closure leading to various underground facilities, such as water, sewage, cable, natural gas, fire pipeline, sanitation, etc., which can also be called the underground door. In the past, metal manhole covers were mainly used in urban roads due to heavy traffic and bearing pressure, but some lawbreakers took the metal manhole covers as money to prevent people's daily travel from being blocked, stole them and then sold scrap iron. Therefore, people walk into the sewage well and the front tire of the vehicle enters into the water well. Compound rainwater grate mold well grate mold rainwater grate mold
