On April 7, the Office of Resources and Environment Technologies of the 863 Program of the Ministry of Science and Technology organized and held a meeting to review key projects for the research and demonstration of key technologies for centralized disposal and disposal of hazardous wastes in Beijing. The acceptance expert group heard the project acceptance report. After being questioned and discussed by the expert group, the group accepted the project acceptance.
The project addresses the major needs for the safe disposal, disposal and management of hazardous wastes in China. It focuses on the national environmental protection plan and is market-oriented. It is jointly undertaken by more than ten production, research and development units such as Hangzhou Dadi Environmental Protection Co., Ltd. Over the past five years since the project was launched, a new type of rotary kiln incinerators for hazardous wastes of complex components has been developed, and hazards such as leakage pollution warning of hazardous waste landfills, seepage prevention of seepage prevention layer, intelligent cleaning, uneven settlement monitoring of heaps, etc. have been developed. Waste treatment technologies and equipment have formed a set of relatively complete hazardous waste treatment and disposal and management technology systems in line with the national conditions. The results of project research and development have been demonstrated in Hangzhou, Luzhou, Taizhou and other cities. Industrial hazardous waste of demonstration projects The incineration volume is more than 50t/d, which can meet the centralized disposal of hazardous waste in large and medium-sized cities in China. It has the prospect of being promoted in large and medium-sized cities in China and can greatly save the high cost and investment costs of the introduction of foreign technologies.
A carbon Steel Plate has usually been considered as the steel that does not contain much alloy steel elements, also named as mild steel. Generally, elements are C, Mn, P, S, Si, besides these, there are no minimum limits for elements of Al, Cr, Ni, Mo, V, etc.
Low carbon steel is the most common form, and it's very malleable and ductile. Medium carbon steel balances ductility as well as strength for excellent wear resistance. High carbon steel is exceptionally strong, while ultra-high carbon steel can be tempered to even greater hardness but no malleability.
As the percentage of carbon gets larger, steel can become harder and stronger through heat-treating. Carbon steel is usually heated to change the mechanical properties of steel, usually ductility, hardness, strength, and resistance of impact. Increasing the carbon content of carbon steel makes it harder and stronger, but reduces the steel`s ability to be welded, making it more brittle.
Carbon steel plate is most often used for structural purposes such as buildings, yet it has the flexibility to be worked into ornate designs. Low carbon steel sheet (wrought iron) is typically used for fences, chain links, gates, and railings. Structural steel (medium carbon steel) is used in cars, refrigerators, washing machines, buildings, and bridges. The steel sheets are normally made up of medium carbon steel.
