China's equipment upgrade lean manufacturing encounters å°´å°¬
Chopped Graphite/Graphite Electrode in different materials have different definition of graphite pieces, some data and literature is not very big graphite particles are called graphite pieces (such as Graphite Powder) some is graphite products have a certain size, for Graphite Broken into patches, we here say of graphite for a second, usually called graphite blocks. Graphite is produced from graphitization and machining process of graphite products. It is used as additive and conductive material in the manufacture of graphite waste in steel and foundry industries, and can also be processed according to customer's requirements. They are also widely used in electric arc furnaces (steelmaking) and electrochemical furnaces (metallurgical and chemical industries).
Main use of graphite
Graphite pieces due to its low ash content, conductive and heat conduction performance is good, so there are a wide range of USES, can be added to the formula of less ash or dust products, graphite broken broken into small particles commonly use. Ingredients to add a certain amount of graphite, the plastic paste after kneading, especially during extrusion can reduce the friction resistance paste to squeeze the mouthpiece, to improve the coefficient of pressure type. Graphite pieces of coal adsorption properties of asphalt is better, to join the carbon block can rise to reduce the "short" waste (i.e., the product after roasting top produce honeycomb structure), and can improve the thermal conductivity of the carbon block and alkali corrosion resistance. The electrode paste used in hermetically-sealed thermal furnace is added to a certain amount of graphite to increase the conductivity and thermal conductivity of the electrode paste and accelerate the sintering speed of electrode paste. When the graphite is ground into small particles or fine powder, it is also used as raw material for the production of graphite chemical equipment (such as graphite-resin tubes). The graphite can also be used as a carbon addition agent for the electric furnace.
Graphite classification
1. Raw and broken. It is a raw blank that is not qualified after molding.
2. Roasting is the cutting debris that is recovered after the roasting of raw billet and after inspection of unqualified waste and the processing of calcined products.
3. The graphite is broken, and it is inspected by the graphite-producing waste and the cutting debris produced by graphite products in the process of processing.

The reporter heard several other CEOs in the Tianjin equipment manufacturing industry, but heard another interpretation. That is, it is not objective to blame the lack of international market competitiveness of Chinese equipment and blame the lack of core technology. Such as poor reliability, high failure rate, short life cycle and other parasitic diseases on Chinese equipment, it is not simply due to the lack of core technology. The weakening of lean manufacturing is undoubtedly an important cause. Only by achieving lean manufacturing, can core technologies fully demonstrate their creative value and social value. The current reality is that many Chinese equipment manufacturing companies that adhere to lean manufacturing are facing an embarrassing situation.
Folding the "price wave"
"Cheap is not good," this is no more straightforward. However, more Chinese equipment users, or subject to limited economic conditions, or relying on the superiority of the buyer's market, have turned the scientific "price-performance ratio" into a false proposition of "high quality and low price", so that the hero will not Ask the source, the price is determined as the sole procurement principle. In this way, it is possible to suffer from equipment manufacturing enterprises that adhere to quality competition.
Wang Lin, general manager of Tianjin Yishan Construction Machinery Co., Ltd., complained to reporters. The “Mengshan†brand is a famous brand in China's bulldozers. It is known for its technological leadership, optimized configuration and excellent manufacturing. Sometimes, because the price is slightly higher than other similar products with poor performance, it may be rejected by users. Jin Yi, director of Tianjin No. 1 Machine Tool Plant, also shared the same feeling. The "China Famous Brand" curved bevel gear CNC machine tools and complete sets of equipment developed by them have reached the international advanced level, and they often lose the price competitive advantage in some users due to the high cost formed by "high-end high-matching". Similar products with low price and quality.
In the old-fashioned state-owned enterprises or state-owned enterprises, such as Yishan and Tianyiji, in order to adhere to high-quality land, adhere to quality competition, and refuse to participate in vicious price competition, some equipment manufacturing enterprises have to protect the existing market and strive for a share of it. Have to bow down in front of the bidding tide, with a lower offer for the bidding tide to help.
As everyone knows, the loss-making business is no one to do. In pursuit of low cost, low allocation has become a shortcut for equipment manufacturers that are keen on price wars. As a result, some brand-name accessory products will be left out under the influence of the price extrusion mechanism. Zhang Shengli, president of SEW China, once expressed his feelings. The SEW reducer that they produce represents the highest level of similar products in the world today. Although it has become the national key project and the first choice for major projects, it has played an important role in the opening and closing ceremonies of the Beijing Olympic Games and the opening ceremony of the Shanghai World Expo. Some ordinary projects have to give way to similar products of other grades. The reason is only that the price is a little higher. He is puzzled by the fact that some users only ask for price and do not consider cost performance.
Seeking a price advantage is not impossible, but cannot be done. The practice of switching to a low price for a price advantage is tantamount to drinking and quenching thirst, and seriously hampers the pace of upgrading China's equipment.
Helpless "technics shortage"
No matter the tooling, the design is advanced, there is no good mechanic, and it is difficult to make first-class products. On the premise of lean manufacturing, this is especially true for technology-intensive equipment.
Jin Yi is deeply touched by this. He told reporters that the curve bevel gear machine tool and complete sets of equipment developed by Tianyiji, the reason why it has the reliability comparable to the world famous brand, is a very important factor. This old-fashioned state-owned enterprise has cultivated and retained a large number of skilled farmers. Excellent mechanics in every manufacturing process.
Wang Lin also has the same perception. The development of China's first crawler-type bulldozer is also famous for its reliable performance and outstanding quality because of its military pedigree, strict discipline, excellent work style and skilled craftsmanship. .
Lu Chao, president of Tianjin Tianhai Synchronizer Group, said more earnestly. In just over a decade, Tianhai Synchronizer can occupy more than 60% of the domestic professional market, and export in batches to the world famous brand, and then create the Chinese era of the synchronizer world. The key is that Tianhaiken spends a lot of money. Ken has made great efforts to cultivate a large number of professional and technical workers. They are an important guarantee for high quality synchronizers.
Different from the above-mentioned enterprises, some equipment manufacturing companies are doing nothing for the lack of skilled workers, so that they have to temporarily hire "migrant workers" to fill the gap. According to the reporter, this situation is not a minority. There is a manufacturer of equipment manufacturing companies who have said that it is difficult to find a good technician than to find ten white-collar workers.
Not to mention what caused the "technician shortage." However, the reality that the skilled workers are seriously lacking has become the pain of many equipment manufacturers. Still, the boss told reporters bluntly that it is difficult to ensure the quality of the products, not to mention the excellence, because of the lack of skilled workers, especially good mechanics. It can be seen that the “technical shortage†has become a major bottleneck for some equipment manufacturing enterprises to achieve lean manufacturing, and even a bottleneck that is difficult to crack in the short term.
