Beiren Successfully Developed a New Roll Paper Printing Machine
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.

BEIRENB624 uses 624mm cutting size to meet the book size of 630mm cutting size. A4 and A5 specifications, saving 6mm per sheet. According to the printing of 400 reams a day, the 630 specifications can save 4 reams of paper/day, and the annual paper-saving amount is considerable.
The printing roller of this model adopts a linear arrangement, which can meet the printing requirements of commercial machines. At the same time, the “shoulder iron†printing method is used to ensure that the printing press runs smoothly and the outlets are accurately restored. The plate cylinder adopts a narrow groove type quick card printing method and an advanced plate positioning wedge positioning method, so that the printing plate positioning is more accurate and stable. At the same time, there is an anti-rising line device installed between the printing units to ensure accurate overprinting.
In the previous market promotion activities, this model has won the favor of many printing companies, and has already obtained the first batch of orders. The model will be officially launched to the market in 2011.
Through the application of a large number of technologies, this machine has the following characteristics:
1. Energy-saving paper, books, commercial printing and take into account;
2. High machine speed, good printing quality;
3. High folding accuracy and high degree of automation;
4. Good after-sales service, no worries.
