Wu Yulin: LED lighting is now "Ice and Fire Two Heavens"

Recently, a young man who is doing LED e-commerce is full of confidence. He talks with me with enthusiasm: how good his current e-commerce business is, how hot the business is, and the daily customer service staff are too busy, every day, the news is frequent, one In the year, there are sales of over 100 million yuan. However, some enterprises that do LED lamps, including several companies with an annual output value of nearly 100 million yuan, are bleak. Most companies lament that this year's business is not good. A few days ago, I went to the Hangzhou market to inspect and found that the situation of the local lighting market in Hangzhou was not optimistic. The price was low to the price of cabbage, the product homogenization was serious, and the business was cold and clear. However, in another non-lighting market, I found an LED bluetooth speaker alarm clock, which is expensive and has a good sales. According to the seller, its online and offline sales can reach 100,000 yuan / month, of which online sales dominate. From the above several cases, we can draw the following summary: 1. The e-commerce model has penetrated into the lighting industry, and the momentum is unstoppable. Many well-selling good products have been quietly moved from offline to online. If you still don't believe in e-commerce, you still don't know and learn e-commerce, then you are really somewhat OUT; 2, LED technology is changing with each passing day, the company purely fights the price, the trick of copying the product is no longer useful. Nowadays, the mainstream of consumer groups is after 80s and 90s. This is a group of people in the Internet age. They have a wide range of information and novelty. They are good at various purchase strategies and subvert the traditional simple trading model. 3. Now, LED lighting products It has changed from a lamp era to a multi-functional era. A single lighting function has no way to meet the quality of life of modern people. With the demands of sex, personality, novelty and convenience, more innovative requirements are put forward for products. LED lighting ice and fire two days, in my opinion is a shuffle in the industry, the ability to lose, the weak are defeated, it is worth reminding: the arrival of the Internet + era, for the lighting industry, enterprises are learning Internet + thinking At the same time, we must pay attention to product innovation and business model innovation, use excellent products to impress consumers, and open a green channel for consumers with convenient and high-quality purchase services.

Chromium Carbide Overlay Blast Furnace Wear Parts

The blast furnace uses steel plates as the furnace shell, and the shell is lined with refractory bricks. The blast furnace body is divided into 5 parts from top to bottom: furnace throat, furnace body, furnace waist, furnace belly and furnace hearth. Due to the advantages of good technical and economic indicators of blast furnace ironmaking, simple process, large production volume, high labor production efficiency and low energy consumption, the iron produced by this method accounts for the vast majority of the world's total iron output.


During the production of blast furnace, iron ore, coke, slag-making flux (limestone) is loaded from the top of the furnace, and preheated air is blown in from the tuyere located at the lower part of the furnace along the furnace periphery. At high temperatures, carbon in coke (some blast furnaces also spray auxiliary fuel such as pulverized coal, heavy oil, natural gas, etc.) burns with carbon monoxide and hydrogen produced by the oxygen blowing into the air to remove iron ore during the ascent in the furnace Oxygen, thereby reducing iron. The molten iron is released from the iron mouth. Unreduced impurities in iron ore combine with flux such as limestone to form slag, which is discharged from the slag port. The produced gas is discharged from the top of the furnace, and after dedusting, it is used as fuel for hot air furnace, heating furnace, coke oven, boiler, etc. The main products of blast furnace smelting are pig iron, as well as by-product blast furnace slag and blast furnace gas.
