- Last year our country mechanical and electrical export share edged up all over the world2016-11-19Vice Minister of Commerce Jiang Yaoping said yesterday, in 2015 China's imports and exports of mechanical and electrical products $1 trillion and 960 billion, an increase of 6.7%. Exports of mechanical and electrical products accounted for a steady increase in the share of the global market, the first 11 months of last year reached 16.1%, 0.9 percentage points higher than in 2014.According to him, China's exports of mechanical and electrical products last year, US $1 trillion and 180 billion, an increase of 8.7%, accounting for 57.6% of the total and incremental foreign trade and 62.4%. At present our country electromechanical products export market has more than 220 countries and regions, emerging market share rose to 29.1%.Jiang Yaoping said that the current lack of global recovery, trade protectionism is on the rise, weakening the traditional competitive advantages of Chinese enterprises, this year our country Electromechanical and high-tech products export growth is facing greater pressure. However, the basis of China's Electromechanical industry is strong, with the development and development of the economy and the industry is highly complementary, the comparative advantage is still exist, the prospect is broad. This year we will vigorously implement the science and technology, through the market diversification and quality strategy, do everything possible to stabilize the electromechanical and high-tech products export, change and pay more attention to structural adjustment and development mode, improve the quality and efficiency of growth.The trade of electromechanical products have int been a "half of the country, China's foreign trade import and export and processing trade last year and accounted for 50.7% of China's foreign trade import and export and 34.8.%, electromechanical exports has remained the largest export category for 18 consecutive years.

- Used mechanical and electrical products import quantity increases the hidden trouble2016-11-19The first half of this year, Shandong inspection and Quarantine Bureau of Qingdao to complete the inspection and Quarantine of imported old mechanical and electrical products in 199 batches, the value of $28 million 996 thousand and 700, compared with the same period last year growth of 9.34%, the value growth of 178.56% batches. The unqualified 22 batch, the value of $3 million 288 thousand and 600, accounted for the province's system of used mechanical and electrical products imported substandard and 23.91% of the value of the total and 23.68%, unqualified products mainly from South Korea, Japan, the United States and singapore. Imported old mechanical and electrical products, there are 6 main reasons for the failure of the main. Mechanical safety hazards. The main performance of the power of the equipment and mechanical transmission parts of the lack of safety warning signs, mechanical danger, no protection device or installation location is unreasonable, the protection distance is not up to standard, inadequate protection measures, etc.. Two electrical safety hazards. The main performance for the use of safety warning color inappropriate, emergency stop button without yellow warning substrate or serious wear, and even loss of function, etc.. Three are health risks. Mainly manifested in the presence of waste oil, health status, etc.. Four is the environmental risks. The main performance of the work of the old equipment when the noise exceeds the prescribed limits. Five is the hidden danger of energy consumption. Some European and American countries and regions of the old mechanical and electrical energy consumption is high, is not conducive to energy saving and emission reduction. Six is fraud risk. Mainly for the arrival of product specifications, production date, manufacturer, origin is not consistent with the filing of the old equipment; re spraying, replacement parts, shell to the "new old charge" to avoid pre shipment inspection. In this regard, the inspection and quarantine departments, through the strengthening of the pre feasibility studies, to improve the rationality of product introduction; explore the establishment of credit system construction risk assessment + + import classification management "of the new mode of regulation, improve the inspection and supervision of the overseas; focus on checks, strict implementation of pre shipment inspection system, improve the inspection and supervision of prospective and strengthen Customs; and the commerce department cooperation, improve the effectiveness of law enforcement.
- What are the classification of the welding electrode price expensive2016-11-19Is the classification of welding electrodes expensiveAccording to the different situation, electrode classification has three kinds of methods: classification, classification, use electrode according to the main chemical composition of the skin according to the characteristics of the coating after melting slag classification. Now let's look at the specific classification method. In accordance with the use of electrodes, electrode can be divided into: structural steel electrode, heat resistant steel electrode, stainless steel electrode, welding electrodes, low temperature steel electrodes, cast iron electrode, nickel and nickel alloy electrodes, copper and copper alloy rods, aluminum and Aluminum Alloy electrode and electrode for special purposes. According to the main chemical components of electrode to classification, can be divided into: Welding titania type electrode, titanium calcium type electrode, ilmenite electrode, iron oxide type electrode, cellulose type electrode, low hydrogen electrode, graphite electrode and base electrode. If the electrode is melted, the classification of the characteristics of slag, welding electrode can be divided into acidic and basic welding electrodes. Acidic oxide as the main component of acid coating, such as silica, titanium dioxide, ferric oxide etc.. The main components of the basic electrode medicine skin are alkaline oxide, such as marble, fluorite and so on. 1, welding rod type according to the mechanical properties of deposited metal, the types of medicine, welding position and welding current types. The following 2 electrode model establishment method: the letter "E" said electrode; the top two digital representation of the tensile strength of the deposited metal is minimum; third digit electrode welding position. "0" and "1" welding to welding in all positions (flat, vertical, horizontal, upward), "2" the electrode is suitable for welding and welding plane, "4" said electrode is suitable for vertical down welding; welding current and said coating type third and fourth digit combinations. Added "R" to the fourth digit after the, the additional "M" indicates the resistance to moisture absorption and mechanical properties of the electrode with special requirements; additional "-1" indicates the impact of the performance of the special provisions of the electrode.
