nm400耐磨板在选择中应该注意哪些问题?

第一,我们选择的时候看一下它产品的性能参数。我们在使用的时候产品的韧性性能参数越好它的安全性也就越好,使用的时候就不容易损坏了,给我们的工作很好的安全保障。
First, when we choose, let's take a look at the performance parameters of its products. When we use it, the better the toughness performance parameters of the product, the better its safety. It is not easy to damage when we use it, which gives us a good security guarantee for our work.
第二,我们选择的时候看一下它的耐磨性。由于nm400耐磨板在使用的时候不停的在磨损,不耐磨的话很块就坏掉了,给我们的使用带来很大的麻烦,我们尽量选择耐磨性高的产品,这样就能使用很长的时间。
Second, when we choose, let's take a look at its wear resistance. As the nm400 wear-resistant plate is constantly worn in use, if it is not wear-resistant, it will be broken, which brings us great trouble. We try our best to choose products with high wear resistance, so that we can use them for a long time.
第三,我们在看nm400耐磨板的时候还要看一下各个厂家对自己生产的nm400耐磨板有没有其他的参数要求,任何厂家只要是有好的工艺和配方就能产出高质量的产品,这是工程中的重要参考,我们要选择实力强的厂家生产的产品。

Third, when we look at the nm400 wear-resistant plate, we should also see whether each manufacturer has other parameter requirements for its nm400 wear-resistant plate. Any manufacturer can produce high-quality products as long as it has good process and formula. This is an important reference in the project. We should choose products produced by strong manufacturers.
nm360耐磨板其在调质时,添加的合金元素比较多,其碳当量在0.49上下,焊接较为非常容易,可是焊接后非常容易发生焊接冷裂痕。为了更好地提升粘聚性,应当尽可能减少焊接连接头的过氧化物量。此外焊接前能够加热,焊接后隔热保温渐渐地制冷。此外选用低碳环保焊接材料,碳成分在0.15下列,低p和s,这种都能够避免出现焊接裂痕。
When NM360 wear-resistant plate is quenched and tempered, more alloy elements are added, and its carbon equivalent is above or below 0.49, so it is very easy to weld, but cold cracking is very easy to occur after welding. In order to improve the cohesion, the amount of peroxide should be reduced as much as possible. In addition, it can be heated before welding and cooled gradually after welding. In addition, the use of low-carbon welding materials, carbon content below 0.15, low P and s, this can avoid welding cracks.
钢筋搭接连接头由nm360耐磨板和Q235B钢板焊接而成,nm360耐磨板抗压强度较高,强度做到了HBW400,屈服强度达到1000多mpa,而Q235B归属于高碳钢,抗压强度较低。因为接头处必须承担冲击性荷载,因此,焊接必须具备一定的疲劳极限,依据钢板的焊接性和应用工作状况,历经综合性考虑到后,采用ER50-6焊条,Ar(80%)+CO2(20%)汽体维护。机器设备选用康佳YW-50KB,交流电接反。
The lap joint of steel bar is welded by NM360 wear-resistant plate and Q235B steel plate. The NM360 wear-resistant plate has high compressive strength, the strength is hbw400, and the yield strength is more than 1000 MPa. Q235B belongs to high carbon steel, and the compressive strength is low. Because the joint must bear the impact load, therefore, the welding must have a certain fatigue limit. According to the weldability and application working conditions of steel plate, after comprehensive consideration, ER50-6 electrode, AR (80%) + CO2 (20%) vapor maintenance are adopted. Konka yw-50kb is selected as the machine and equipment, and the alternating current is connected reversely.
在焊接前严苛清除焊缝及两边30mm范畴内的油渍、锈迹等残渣。对焊缝开展渗透检测,无层次、裂痕、参杂后才可焊接,不然务必消除,并检验达标后焊接。焊接前用氧火苗匀称加温焊缝两边100毫米范畴至150~200℃,选用ER50-6焊条点固,点固后马上焊接。在点固焊接的全过程中,维持固层溫度150~200℃,选用红外线测温仪温度测量。焊接选用小线动能,双层多道焊,固层清除完全,并严控固层溫度。收弧时弧坑务必铺满,避免造成弧坑裂痕
Before welding, strictly remove oil stains, rust and other residues within 30mm of the weld and both sides. Carry out penetrant testing on the weld, and weld only after there is no layer, crack or impurity, otherwise, it must be eliminated, and weld after reaching the standard. Before welding, use oxygen flame to evenly heat both sides of the weld 100 mm to 150 ~ 200 ℃, use ER50-6 welding rod for spot welding, and weld immediately after spot welding. In the whole process of spot welding, the temperature of solid layer should be maintained at 150 ~ 200 ℃, and the temperature should be measured by infrared thermometer. Small line kinetic energy is used for welding, double layer multi pass welding is adopted, solid layer is completely removed, and solid layer temperature is strictly controlled. When the arc is stopped, the crater must be covered to avoid cracks
总之,我们要想选出好的nm400耐磨板,就要多看几家nm400耐磨板厂家的产品,多家对比,这样我们就能选出性价比高,价格优惠的nm400耐磨板了,以上这些大家可以作为参考帮助我们快速的选出我们想要的东西。
In short, if we want to choose a good nm400 wear-resistant plate, we need to see the products of several nm400 wear-resistant plate manufacturers and compare them. In this way, we can choose the nm400 wear-resistant plate with high cost performance and favorable price. The above can be used as a reference to help us quickly choose what we want.
