Recently, Yang Chuantang, Minister of the Ministry of Transport, presided over a special meeting to study and deploy the priority development work of urban public transport. He stressed that it is necessary to closely implement the major strategic deployment of the Party Central Committee and the State Council on the priority development of urban public transportation, with the goal of achieving priority development of urban public transport and equalization of urban and rural passenger transport services, further enhancing awareness, innovative ideas, and coordinated promotion. The policy of giving priority to the development of urban public transport takes root, and effectively realizes, maintains and develops the fundamental interests of the people. PTA Powder
Main application:Repair and
strengthen workpiece surface, significantly
Welding method:PTA welding
Main equipment:PTA welding
machine
Flame core temperature: about 10000℃
Technological characteristics:PTA has high
temperature, concentrated energy, stable combustion, small heat affected zone,
fast welding speed, high production efficiency, easy to obtain low dilution
rate of surfacing layer, surfacing layer and workpiece matrix are metallurgical
bonding,, bonding strength is high.
PTA welding technology is one of surface
strengthening methods, which has high deposition rate, low dilution rate, and
could be applied with many kinds of powder. The manufacturing craft of PTA
powder is normally gas atomization, which reduces satellite of powder. We
supply 4 main categories of PTA powder: Nickel-based alloy powder, Iron-based
alloy powder, Cobalt-based alloy powder and Mixed Powder.
Nickel Based Alloy Powder possesses high
temperature resistance and wear resistance, it is the most popular alloy powder
applied by PTA welding both domestically and internationally. Coating hardness
is within the range of HRC 30-60. It could be applied to various industries
like agriculture, plastic, paper, marine and steel making where wear and
corrosion protection needed. Some examples are plunger, moulds, pump leaf and
screw.
Iron Based Alloy Powder is more widely used
and a more economic choice. With high abrasive resistance, it is more commonly
applied to mining tools, drilling tools and mixers of iron and steel making
industry, coal industry, shaft, oil and energy industry.
Cobalt Based Alloy Powder is recommended
for corrosion and oxidation resistance, with better hot hardness values than
equivalent Nickel based alloy powder. It is widely applied to steel making
industry, coal industry and mining industry.
Mixed powder mainly refers to NiCrBSi
mixing with other hard-phase powder such as cast tungsten carbide and other cemented
alloy powder, which allows the powder better hardness around HRC60 and
excellent abrasion resistance.
Mixed powder is more often used for mining
equipment for oil sands, lignite, oil drilling tools, excavator buckets,
extrusion screws for plastic processing, grain and oil processing, etc.

Yang Chuantang pointed out that since 2008, under the strong leadership of the Party Central Committee and the State Council, the Ministry of Transport and the relevant departments have actively explored the priority development of urban public transport, in the aspects of urban public transport legislation, standard revision and public transport city creation. He has done a lot of work and accumulated a lot of mature experience. He has played an important role in promoting the scientific development of urban public transportation and achieved remarkable results.
Yang Chuantang emphasized that at present, the development of urban public transportation has entered a new historical stage, the demands of the people are getting higher and higher, and the tasks of serving the new urbanization construction and the goal of a well-off society are becoming more and more important. At present and in the future, we must focus on seven aspects of work by continuously satisfying the growing traffic demand of the people. The first is to correctly handle the relationship between the government and the market. The second is to promote the "Regulations on Urban Public Transportation" and supporting regulations as soon as possible, and initially establish an urban passenger transport standard system that meets the needs of the development of the industry. The third is to accelerate the study and formulation of key systems such as bus cost pricing reform, bus subsidy compensation system, public transport development level performance evaluation system, and government purchase of public transportation service system. The fourth is to strengthen the assessment of the implementation of relevant policies, strengthen supervision and inspection, and improve policy implementation. The fifth is to further strengthen the urban public transport safety management work and comprehensively improve the safety and prevention capabilities. The sixth is to further integrate the bus priority development carrier, conscientiously summarize and timely promote the implementation experience of the “bus city construction demonstration projectâ€, and accelerate the study and formulation of the “urban and rural transportation integration construction project†implementation plan. Seventh, scientifically determine the development goals, work tasks and policy measures of the “13th Five-Year†urban public transport, and realize the classification guidance for the development of public transport in different types of cities. Liu Xiaoming, member of the party group and director of the Transportation Department, attended the meeting. The responsible comrades of the relevant departments of the ministries and agencies attended the meeting.
