HBC digital currency
Haobao was launched online on January 1, 2015, and the main mining point is to break through the local tyrant stronghold. Mining assistance: site sign in, transaction specialist, transaction confirmation, issue confirmation, advertising display
Haobao is committed to creating a local version of bitcoin. It is the first to create features such as convenient mobile phone mining, extremely fast offline trading, lifetime currency holding income, and zero handling charges. Its goal is to make Haobao a global currency
Haobao's distribution code is completely open-source, inherits the principle of digital currency decentralization, and creates the technology of rapid data reorganization. As long as HaoYou's spirit remains unchanged, Haobao can continue to develop
Haobao has the privilege of holding money income, and shares the profits of local tyrants (Haobao Fund)
Haobao has created a perfect off-line trading mode (haodou). The value of haodou is not affected by the fluctuation of Haobao's value, and every 100 haodou is equal to RMB 1.
T in steel T10 (T10 carbon tool steel) means carbon tool steel (high carbon)
The strength and wear resistance ofT10 carbon tool steel are higher than those of T8 and T9, but the hot hardness is low, the hardenability is not high, the quenching deformation is large, the grain size is fine, it is not easy to overheat ring quenching, and the fine grain structure can still be maintained
After quenching, there are undissolved carbides in the steel, so the wear resistance is high. It is used to make tools with sharp edge and a little toughness. Suitable for manufacturing, poor cutting conditions All kinds of tools with high toughness and sharp edge are also used as wear-resistant parts Mechanical properties and hardness: annealed, ≤ 197hb, indentation diameter ≥ 4.30mm; Quenching, ≥ 62Hrc heat treatment specification: sample quenching 760 ~ 780 ℃, water coolingquenching T10 steel, recommended quenching specification is shown in table 2-22-7, cold treatment is shown in table 2-22-8, quenching related curve is shown in Fig. 2-22-7 ~ Fig. 2-22-13
The physical properties ofT10 steel are shown in Table 1-1 and table 1-2; Permeability μ 88 MH / m; The coercivity HC is 477.48 ~ 1273.18a/m (the lower limit of HC is suitable for spheroidized structure, and the upper limit is suitable for pearlite structure); The saturation magnetic inction BS is 1.93 ~ 1.97t
the die cavity of cold heading die made of this steel is deep and steep, early collapse failure often occurs in use, and the service life of the punch is less than 4000 times. It is analyzed that the reason is that the feed rate of cavity grinding is too large and the burn is softened. After the improvement of grinding process, the service life of light punch is significantly increased, and it is stable at more than 30000 times
when the steel is used to make cold punching die, the tool can punch about 30000 times for each grinding; When the same thickness of black iron sheet (hot rolled steel plate) is used, the service life will be reced to about 17000 times. Although there is no oxide scale on the surface of semi hot rolled plate, there is a "hard shell", which will seriously rece the service life of the die
I'm using pocket magic box cloud computer now. It's free for one hour every day. It's a lot of free time. It's enough to play a large-scale online game. I usually like to play hero League. Now he is also a member of his family, recharge to send gold coins, preferential strength is very big
