不锈钢铸铁井盖的防爆方法你知道哪些?

来源:http://www.jnwszy.com添加时间:2022-04-06 14:06:02

我们都知道,不锈钢铸铁井盖具有许多优异的特性,例如较高的抗压强度、塑性变形、延展性、耐磨性能、耐热或超低温、抗腐蚀及其规格可靠性这些,但就算是这般,它在冬季平均气温较为低的情况下也非常容易产生爆裂,那么如何防止呢?

We all know that the stainless steel cast iron manhole cover has many excellent characteristics, such as high compressive strength, plastic deformation, ductility, wear resistance, heat resistance or ultra-low temperature, corrosion resistance and specification reliability. But even so, it is very easy to burst when the average temperature in winter is relatively low. So how to prevent it?

针对球墨铸铁井盖篦子自身而言,在一定的平均气温下危害并非挺大。那由于井盖篦子有不错的延展性,又有钢的抗压强度,有不错的拉伸强度,促使井盖篦子在冬季超低温下还可以优良的运作工作中。

For the ductile iron manhole cover grate itself, the harm is not very great under a certain average temperature. Because the well cover grate has good ductility, compressive strength of steel and tensile strength, the well cover grate can operate well under ultra-low temperature in winter.

但球墨铸铁篦子爆裂也无可避免,要想合理防止得话关键还是在于球墨井盖篦子中流体力学的物质,假如流体力学零界点较为低,能够根据适度添加混凝土防冻剂,或是是对球墨井盖篦子开展适度隔热保温解决,来防止在冬季较低温度爆裂。

However, the bursting of nodular cast iron grate can not be avoided. If you want to reasonably prevent it, the key lies in the hydrodynamics materials in the grate of nodular well cover. If the zero boundary point of hydrodynamics is relatively low, you can add concrete antifreeze appropriately or carry out appropriate thermal insulation for the grate of nodular well cover to prevent bursting at a lower temperature in winter.

也有一种对策可以降低铸铁篦子在冬季的爆裂概率,那便是挑选具备不错超低温抗冷材料的原材料制做球墨铸铁井盖篦子,而且在制做中必 须有较高的技术性对策,那样能够使其在超低温下优良工作中。

There is also a countermeasure to reduce the bursting probability of cast iron grate in winter, that is to select raw materials with good ultra-low temperature cold resistant materials to make nodular cast iron manhole cover grate, and there must be high technical countermeasures in the manufacture, so that it can work well at ultra-low temperature.

以精 密铸件皮带盘为例,铸钢件用到的更多一些,由于球墨铸铁篦子商品出成率没有灰铁高,且事后生产加工也比灰铁要难。球墨铸铁井盖篦子的加工过程中,在调质处理、抛丸除锈清 除后或机械加工常常会发觉一些孔眼,严重危害了商品的品质。铸钢件具备优良的锻造特性、减震性、耐磨性、钻削生产加工特性及其低的空缺敏 感度,特别适合用于锻造皮带盘。

Taking the belt pulley of precision casting as an example, steel castings are used more. Because the commodity yield of nodular cast iron grate is not as high as that of gray iron, and the post production and processing is also more difficult than that of gray iron. During the processing of nodular cast iron manhole cover grate, some holes are often found after quenching and tempering treatment, shot blasting and rust removal or machining, which seriously endangers the quality of goods. Steel castings have excellent forging characteristics, shock absorption, wear resistance, drilling production and processing characteristics and low vacancy sensitivity. They are especially suitable for forging belt pulley.
