NM500耐磨板|NM450耐磨板厂家价格

HARDOX450耐磨板 废水零排放模式具有如下特征:
Hardox450 wear-resistant plate wastewater zero discharge mode has the following characteristics:
1) 有效降低全厂水处理建设成本和运行费用:
1) It can effectively reduce the construction cost and operation cost of water treatment in the whole plant
其一，避免全厂大循环运行模式，降低水处理规模。
First, avoid the large cycle operation mode of the whole plant and reduce the scale of water treatment.
其二，生产废水预处理选择稳定高效且普适性强的“高效沉淀池+ V 型滤池”工艺。
Secondly, the stable, efficient and universal "high efficiency sedimentation tank + V-type filter" process is selected for the pretreatment of production wastewater.
其三，选择废水反渗透和浓水反渗透系统作为废水减量化、资源化的手段，相比蒸发结晶投资与运行成本较低。
Thirdly, choosing wastewater reverse osmosis and concentrated water reverse osmosis system as the means of wastewater reduction and resource utilization, the investment and operation cost is lower than evaporation crystallization.
2) 充分利用炼铁、炼钢、烧结、原料场等单元消纳“浓盐水”的能力，将减量后的“浓盐水”进行接收和完全消纳，在全厂层面上实现废水零排放。
2) Make full use of the capacity of ironmaking, steelmaking, sintering, raw material yard and other units to absorb the "concentrated brine", and receive and completely absorb the reduced "concentrated brine", so as to realize zero wastewater discharge in the whole plant.
HARDOX500耐磨板力学性能要求
Mechanical property requirements of hardox500 wear resistant plate
在机器制造业中，耐磨板常用来制造各种轴类零件、连杆、高强度螺线受力状况比较复杂。
In the machine manufacturing industry, wear-resistant plate is often used to make various shaft parts, connecting rod, high-strength spiral, the stress condition is more complex.
例如，轴类零件在工作时，既传递转矩又承受弯曲作、系承受的力是交变的动负荷应力；有时还承受一定的冲击载荷作用；还有些要其他配合件作相对运动，产生摩擦和磨损。

For example, when shaft parts are working, they not only transmit torque but also bear bending force. The force they bear is alternating dynamic load stress. Sometimes they also bear certain impact load. Some other parts need to move relative to each other to produce friction and wear.
因此，对调质钢的力学性能要求是：高的屈服强度和疲劳强度，耐磨钢板韧度和塑性，即具有良好的综合力学性能。
Therefore, the requirements for mechanical properties of quenched and tempered steel are: high yield strength and fatigue strength, toughness and plasticity of wear-resistant steel plate, that is, good comprehensive mechanical properties.
同时，还要考虑调质钢的断裂韧度度和疲劳裂纹扩展速率等性能。一般调质钢的力学性能范围大致为：抗拉强度801200MPa，屈服强度700～10004Pax，伸长率8％～15％、冲击韧度ak＝60～120cm2，韧脆转变温度低于－40℃。
At the same time, the fracture toughness and fatigue crack growth rate of quenched and tempered steel should be considered. The range of mechanical properties of general quenched and tempered steel is as follows: tensile strength 801200mpa, yield strength 700 ～ 10004pax, elongation 8% ～ 15%, impact toughness AK = 60 ～ 120cm2, ductile brittle transition temperature below - 40 ℃.
