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.

The government promoted 150 million LED lighting products through financial subsidies. According to the response of the relevant departments, the price of energy-saving lamps is too expensive to be solved. Indoor lighting involves thousands of households. After the real popularity of led lighting, the market for indoor lighting is larger than the market for outdoor lighting. LEDs are used in indoor lighting, especially in the rendering of atmosphere, and have the unparalleled advantages of any other light source in the past, but At present, in terms of the domestic market, the price is still too high, and most ordinary people still cannot afford it. The specific analysis may be caused by the following factors:
The core technology cost is too high. Most of the core patents in the upstream of the led industry are in the hands of foreigners. We don't have the core technology. Although our LED application product manufacturing capacity accounts for 50% of the world, the share is 50, but the profit is the lowest. A ring.
LED chips adopt a larger size wafer manufacturing process with the increase of process and quantity, which will continuously reduce the cost. In recent years, the speed of 20 is reduced every year, and the price factor of LED chip is also included in the price reduction. Buy a better product at the same price. The cost of LED lighting is mainly in the LED chip. As long as the price of the chip is lowered, the lumen price of the LED can be reduced to the equivalent of the current energy-saving lamp, and the indoor lighting will naturally bloom everywhere. LED chips also have a lot of room for price cuts.
Reasonable design of heat dissipation The cost structure design accounts for about 20% of the lamps and lanterns. The Chinese industrious people have always been very low in price. The 20 cost is considered reasonable. The biggest problem is how to be more innovative and more reasonable in design.
The cost of heat dissipation should be maintained at 5, the actual heat dissipation design is very simple, and the two directions are kept: First, the shorter the path between the LED chip and the external heat sink, the shorter the heat dissipation design is. The second is the heat dissipation resistance. It is necessary to have enough heat to pass to the path and also have enough heat dissipation road. This part of the cost is mainly in the structure, and the cost of cooling is not much.
The power supply cost is seriously lagging behind. The power supply is the weakest link of LED lamps. The development of LED lamps is seriously delayed, and the quality needs to be improved. Now the design accounts for about 20 of the cost of the lamp, and some are high. With the development of technology, the power supply is probably at 5-10.
The high cost of LEDs is actually compared with other current light sources. As the LED industry that invented blue LEDs in the 1990s, which led to the realization of LED white light, the current cost is not high. In particular, LED is environmentally friendly, energy efficient, and contains no mercury. Moreover, the price of LED lamps is declining every quarter. It is believed that it will reach a level acceptable to people in a short period of time.
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.
