Industry researchers pointed out that before the strong earthquake in Japan, there has been an investment boom in the domestic excavator market. Domestic brands represented by leading enterprises are gradually eroding the market share of foreign brands by as much as 70%, and experienced the market of construction machinery in 2010. With rapid growth, the domestic excavator market has attracted more and more capital and vitality. This force is continuously improving the overall strength of domestic brands.
Although the strong earthquake in Japan has not caused a great impact on the construction machinery market, due to the large differences in the trading degrees of different plates, the second-hand excavator market and the important parts and components plate may react to a certain extent. During the period of 2010, Korean-based brands based on end markets have shown a downward trend. Chinese companies are moving from low-end markets to high-end markets. The construction of brands is very prominent, including the use of marketing tools, and brand promotion is gradually maturing. Change.
In January 2011, China's major excavator manufacturers sold more than 10,000 units, and the market continued to grow at a high rate last year. In February, 24 excavator companies sold more than 20,000 units, a year-on-year increase of 134.95%, which doubled again; of which 206 were export sales, which was a year-on-year increase of 106.00%. Although the year-on-year increase was larger, it was down from the previous quarter. Because the promotion of market demand in the previous quarter and the consideration of inventories were taken into consideration, domestic brand promotion measures were very strong and the market share increased rapidly. Therefore, if this promotion rate can continue to be maintained, the domestic brand market share in the first half of the year is expected to reach a new level. The high point.
Spirals are mainly used for stirring, mixing and other functions in pipeline transportation. The spiral surface of the screw conveyor has a solid spiral surface. , belt spiral surface and blade spiral surface transparent form.
The cold rolling mill is an advanced equipment that continuously rolls blades from strip steel. By adjusting the position (roll offset, feed height, roll pressure, guide wheel, etc.), it can roll out blades of various specifications required.
Advantages of cold rolling layout:
It has the advantages of high production efficiency, saving raw materials, good blade quality, high hole diameter, and good wear resistance.
The structures that affect the rolling shape include the material and thickness of the strip, the offset of the roll, the feeding height, the rolling force of the roll, the different specifications of the guide wheels and blades, and the increase in the temperature of the roll during the rolling process. After years of construction, the contract developed this continuous cold-rolled propeller, which has the advantages of smooth surface, high hardness, wear resistance, one-time forming, and continuous no welds.
