Wear-resisting Steel Plate is composed of low Carbon Steel Plate and alloy wear-resisting layer. When working, the matrix provides comprehensive properties such as strength, toughness and plasticity of resisting external forces, and the alloy wear-resistant layer provides wear-resistant properties that meet the requirements of specified working conditions.
Wear-resisting steel alloy wear-resisting layer and base plate are metallurgical combination. By means of special equipment and automatic welding process, the high-hardness self-protecting alloy wire is uniformly welded on the substrate, and the composite layers are one to two or even more. In the composite process, due to the different shrinkage ratio of the alloy, uniform transverse cracks appear, which is a significant feature of the wear-resistant steel plate.
The wear resistant layer of the alloy is mainly chromium alloy, while manganese, molybdenum, niobium, nickel and other alloys are added. The microhardness of carbide can reach above hv1700-2000, and the surface hardness can reach hrc58-62. Carbide alloy has a strong stability at high temperature, maintain a high hardness, but also has a good oxidation resistance, within 500℃ completely normal use.
The wear-resistant layer has narrow channel (2.5-3.5mm), wide channel (8-12mm), curve (S, W), etc. It is mainly composed of chromium alloy, while manganese, molybdenum, niobium, nickel, boron and other alloy components are added. With 40-60% carbide content, the microhardness can reach above HV1700 and the surface hardness can reach hrc58-62.

The petrochemical association has held an industry-wide informatization conference every year since 2003, and it has now become a brand meeting with influential information in the industry.
It is reported that this conference is divided into development conference, system application forum and information security forum. China Academy of Engineering, National Informatization Expert Consultation Committee, Ministry of Land and Resources, Oil and Gas Resources Strategic Research Center, National 863 Research Group, Tsinghua University, China National Petroleum and Natural Gas will be invited. Leaders and experts from group companies and China Petrochemical Corporation came to the meeting and made special reports. At the same time, representatives from key companies will make presentations and exchanges of experience, and technology suppliers will conduct product recommendations and case studies. Contents concerning the significance and impact of the integration of industrialization and informatization, the construction of oil and gas resources database, the supporting role of information technology in enterprise innovation, the value analysis of deepening application of ERP, the role of information technology in promoting energy saving and emission reduction, protection of information security level, and anomalies Flow control, Internet usage control and security management, and typical application mode recommendations.
Petrochemical industry information development conference will open
The sixth "2008 China Petroleum and Chemical Industry Informatization Development Conference" sponsored by the China Petroleum and Chemical Industry Association and organized by the China Chemical Industry Economic and Technological Development Center will be held in Dalian from June 19 to June 20. The theme of this conference is "informatization promotes enterprise management innovation."
