选择山东球墨铸铁井盖的人越来越多?

来源:http://www.kpp647.com添加时间:2020-04-21 13:45:26

球墨铸铁井盖有很高的强度和良好的韧性,所以球墨铸铁井盖比相同类型的轻30%灰口铸铁井盖。球墨铸铁的品牌采用qt500-7,铁水温度不低于1456℃,球状治疗期间,添加稀土镁硅铁合金和含硫量较低的选择可口可乐,球状年级三个或更多。球墨铸铁试件的力学性能如下:

  The ductile iron manhole cover has high strength and good toughness, so it is 30% lighter than the same type of gray iron manhole cover。 The brand of nodular cast iron adopts QT500-7, the temperature of molten iron is not lower than 1456 ℃, during the globular treatment, Coca Cola is selected for adding rare earth magnesium silicon iron alloy and low sulfur content, with three or more globular grades。 The mechanical properties of ductile iron specimens are as follows:

  拉伸强度:500N/MM

  Tensile strength: 500N / mm

  延伸率:7%

  Elongation: 7%

  人孔盖试压失效载荷超过国家行业标准;

  The pressure test failure load of manhole cover exceeds the national industry standard;

  采用准则如下:

  The guidelines are as follows:

  CJ/ t3012-93铸铁人孔盖检验标准

  CJ / t3012-93 inspection standard for cast iron manhole cover

  EN124车道行人路的排水渠盖及沙井盖

  Drainage channel cover and manhole cover of pedestrian road in en124 Lane

  人孔盖与底座尺寸偏差符合国家标准

  The dimension deviation between manhole cover and base conforms to the national standard

  铸铁天沟盖板尺寸:轻:25吨/平方米,有车,步行进入校园住宅公园,公园,地下停车场和厨房。

  Cast iron gutter cover size: Light: 25 tons / m2, with car, walking into campus residential park, park, underground parking lot and kitchen.

  重型:70吨/平方米,不足20吨的车辆通过厂区,一般道路,球墨铸铁井盖工艺特点主要道路路边,停车场和街道。

  Heavy duty: 70 tons / m2, less than 20 tons of vehicles pass through the plant area, general roads, ductile iron well cover process features main road side, parking lot and street.

  超重型:140吨/平方米,重型拖车、集装箱叉车、吊车、飞机等。

  Super heavy: 140 tons / m2, heavy trailer, container forklift, crane, aircraft, etc.

  特点:

  characteristic:

  1、热浸镀锌表面处理:具有较强的防锈性。

  1. Hot dip galvanizing surface treatment: with strong rust resistance.

  2。 防盗门设计:沟盖采用钢格栅板制作,与框架铰链连接,防盗、安全、易开启

  2. Anti theft door design: the trench cover is made of steel grating plate, connected with the frame hinge, anti-theft, safe and easy to open

  3、产品外观美观:线条简单,外观银色,理念现代

  3. Beautiful product appearance: simple lines, silver appearance, modern concept

  4、网孔带排水:泄漏面积为83。3%,是铸铁的两倍以上。

  4。 Mesh with drainage: the leakage area is 83。3%, more than twice that of cast iron。

  5、节省材料和投资:跨度大,负荷重,价格低于铸铁;并可节省铸铁盖由于盗窃或破碎和更换成本。

  5. Saving material and Investment: large span, heavy load, lower price than cast iron; and saving cast iron cover due to theft or breakage and replacement cost.

  6、采用高强碳素钢,使钢格具有很高的强度:强度和韧性远高于铸铁,可用于码头、机场等大跨度和重载环境。

  6. Using high strength carbon steel, the steel grid has high strength: its strength and toughness are much higher than that of cast iron, which can be used in large span and heavy load environments such as docks and airports.

  7. 产品种类:可满足不同环境、荷载、跨度、形状的要求,并可根据客户要求提供尺寸和形状。

  7。 Product type: it can meet the requirements of different environments, loads, spans and shapes, and can provide dimensions and shapes according to customer requirements。
