In the future, China's steel industry will return to rational growth
According to the research on the steel industry, the application of automation products for new projects in the steel industry will be in a stable development trend in the future; under the influence of industrial structure upgrading and energy conservation and emission reduction, the demand for automation products of the transformation project will increase.
Since the outbreak of the financial crisis, the steel industry has always been in a state of high production and low efficiency. In 2011, this situation has become more apparent. From January to November 2011, China produced a total of 630.984 million tons of crude steel, an increase of 9.8% year-on-year. Under the influence of factors such as the general economic decline in major developed countries, domestic monetary tightening and real estate regulation and control, the demand for steel in the market has decreased drastically, steel prices have fallen sharply, and the profitability of steel companies has become very difficult. From January to October, 77 large and medium-sized steel companies that included statistics achieved a profit of only 84.17 billion yuan, and the sales profit margin was only 2.7%. In October and November, the profit margin of steel companies was only 0.47% and 0.43%.
The profit rate has fallen to an all-time low, but the increase in investment has accelerated, which has intensified the pressure on overcapacity in the steel industry. In the first 11 months, the fixed assets investment completed by the Chinese steel industry increased by 18.6% year-on-year, while the investment growth in the first 11 months of 2010 was 5.3%, and the growth rate accelerated by 13.3 percentage points year-on-year.
According to the comprehensive forecast of the Ministry of Industry and Information Technology, the domestic crude steel-oriented consumption in 2015 was about 750 million tons. Due to the dual impact of fixed investment and steel “reduction†during the “Twelfth Five-Year Plan†period, China's steel industry will return to rational growth in the future.

Diamond cutting piece is a widely used in stone, concrete, precast board, new and old roads, ceramics and other hard brittle materials processing.
Diamond cutting pieces are mainly composed of two parts; Matrix and cutter head,
The matrix is the main support part of the bonding tool head, and the tool head is the cutting part in the process of use.
The tool head will be constantly consumed in use, while the matrix will not. The reason why the tool head can play a cutting role is that it contains diamond. Diamond, as the hardest material at present, cuts the processed object by friction in the tool head, while diamond particles are wrapped in metal inside the tool head.
According to the shape of the knife head, there are different effects:
1. Continuous edge Saw Blade: continuous saw diamond cutting blade, generally made by sintering method, water must be added when cutting to ensure the cutting effect, and the type of gap will be cut by laser.
2, knife head cutting piece: serrated disconnect, cutting speed, suitable for dry and wet cutting methods.
3, corrugated cutting piece: combined with the advantages of the first 1, 2, serrated continuous corrugated uniform convex and concave, improve the cutting speed, increase the service life.
