关于球墨铸铁井盖你知道多少?

来源:http://www.kpp647.com添加时间:2019-10-18 09:58:00

  球墨铸铁井盖你晓得是什么吗?相信大家听到这个名字还是很生疏,关于这个球墨铸铁井盖是充溢了疑问,到底球墨铸铁井盖在市场上起着什么样的作用呢?今天就一同来讨论一下。

  Do you know what a ductile iron manhole cover is? I'm sure you're still unfamiliar with this name. There are many questions about this ductile iron manhole cover. What kind of role does it play in the market? Let's talk about it today.

  据理解,城市展开的需求以及产品材质的改良,都会使消费厂家迎来新的一轮展开。新型球墨铸铁防盗井盖所用资料为特地定点消费厂的优秀球铁生铁、焦炭和专用球化剂球化等级控制在1级~2级范围内外观精密颜色与沥青面层比拟接近且混凝土井环可不露表面在保证平整度的前提下井盖融入路面与道路成为抵达城市的效果。而旧式灰铸铁井盖由于自身井盖颜色灰暗外观粗糙混凝土井环必需外露沥青面层颜色与沥青面层不分歧且平整度难于控制与道路难于是城市的一个难点。

  It is understood that the demand for urban development and the improvement of product materials will usher in a new round of development for consumer manufacturers。 The data used for the new type of nodular cast iron anti-theft manhole cover is that the excellent nodular cast iron, coke and special nodular agent of the special designated Consumer factory are controlled within the range of level 1-2, and the precise color inside and outside is close to that of the asphalt surface layer, and the concrete well ring surface is not exposed before the manhole cover is integrated into the road and the road to ensure the flatness, which becomes the effect of arriving at the city。 However, due to the color of the old gray cast iron well cover, the color of the exposed asphalt surface of the rough concrete well ring is different from that of the asphalt surface, and the flatness is difficult to control and the road is difficult to control。

  山东球墨铸铁井盖

  新型球墨铸铁井盖采用球墨铸铁QT500-7材质,进步产品的密度,使该产品具有很强的抗压、抗弯、抗冲击、耐热、耐寒、耐磨、耐酸碱、耐老化、不易变形等特性。精致的铸造工艺使产品纹路明晰,井盖外表有共同的防滑图案,增加摩擦力,预防因雨、雪、冰掩盖使行人滑倒。

  The new type of ductile iron manhole cover is made of QT500-7 material, which improves the density of the product, making the product have strong compression resistance, bending resistance, impact resistance, heat resistance, cold resistance, wear resistance, acid and alkali resistance, aging resistance, and deformation resistance. The exquisite casting technology makes the product lines clear, the well cover has a common anti-skid pattern on the surface, increases friction, and prevents pedestrians from slipping due to the cover of rain, snow and ice.

  污水井盖在市政井盖系列中有着十分重要的位置,由于污水井里面的水都是比拟脏的污水,所以井盖的安全水平十分关键,必需是合格的污水井盖才干完好可以抵达运用央求,污水井盖内径尺寸大局部都是70cm。山东铸铁污水井盖采用球墨铸铁资料,球墨铸铁井盖强度高、韧性好,因而球墨铸井盖比同类型灰口铸铁井盖轻30%左右。球墨铸铁牌号采用QT500-7,铁水出炉温度不低于1456℃,在球化处置时增配稀土硅铁镁合金和选用含硫量低的焦碳,球化级别达三级以上。球墨铸铁试件的力学性能如下:抗拉强度:500N/MM 2 延伸率:7%井盖试压毁坏荷载超越国度行业规范。

  The sewage well cover plays an important role in the municipal well cover series。 Because the water in the sewage well is relatively dirty sewage, the safety level of the well cover is very important。 Only qualified sewage well cover can reach the application requirements in good condition。 The internal diameter of the sewage well cover is 70cm in most cases。 According to the data of nodular cast iron, the strength and toughness of nodular cast iron manhole cover are high, so it is about 30% lighter than the same type of gray cast iron manhole cover。 QT500-7 is adopted for nodular cast iron, and the temperature of molten iron is not lower than 1456 ℃。 Rare earth ferrosilicon magnesium alloy and coke with low sulfur content are added during nodularization, and the level of nodularization is above grade III。 The mechanical properties of nodular cast iron are as follows: tensile strength: 500N / mm2 elongation: 7% well cover pressure test failure load exceeds the national industry code。

  铸铁污水井盖运用环境:大型矿山、机场、码头、重载机动车道路、市政快车道。760重型井盖可用做污水井盖、给水井盖、消防井盖等。山东铸铁污水井盖共同特性:防盗,井盖与井座一体化衔接,新的防盗方式:内防盗,不影响美观,大锤砸不烂,完好防盗!承严重,球墨铸铁的拉力及韧性是普通铸铁的四倍,接近于钢的材质,合适各种道路运用!耐腐蚀,下水井内环境复杂,各种化学物质充溢,球墨铸铁不受化学物质的腐蚀,运用寿命30年以上。

  Application environment of cast iron sewage well cover: large-scale mine, airport, wharf, heavy-duty vehicle road, municipal expressway。 760 heavy well cover can be used as sewage well cover, water supply well cover, fire well cover, etc。 Shandong cast iron sewage well cover common characteristics: anti-theft, well cover and well seat integration connection, new anti-theft way: internal anti-theft, does not affect the appearance, hammer smash not rotten, intact anti-theft! Bearing serious, ductile iron tensile force and toughness is four times that of ordinary cast iron, close to the material of steel, suitable for all kinds of road use! It is corrosion-resistant, the environment in the water well is complex, all kinds of chemical substances are overflowing, nodular cast iron is not corroded by chemical substances, and its service life is more than 30 years。
