The communication methods provided by the instant messaging software have evolved. Following the WeChat voice intercom and video calls, the instant messaging software LINE officially launched yesterday the function of video calls and microsecond videos that can be uploaded within 10 seconds. The addition of more stereoscopic audio and video elements, whether it will further erode the telecom-related service market, or spark sparks in other markets, is worthy of attention.
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.

LINE announced yesterday that the global launch of the new 3.9.0 version, the new version update, the addition of two new audio-visual related features, one of them is a one-on-one video call, the second is a video feature that allows users to display in the personal space and Share personalized short films that last 4 to 10 seconds, and you can also play with background music of your choice.
LINE Taiwan Vice President Tao Yunzhi stated that LINE's positioning is a software that helps relatives and friends share life and strengthen communication, and constantly expands diversified communication channels. This two new functions also represent LINE's progress in this long-term direction.
LINE is not the first example of this kind of service. In recent years, in addition to the ancestor Whatsapp is sticking to the existing pure text communication field, a variety of application software has developed a variety of communication features, and WeChat has featured the voice intercom function.
