    The enterprise to product quality is the pursuit of continuous technological innovation, keep "Longxing, " products vitality, for users and create greater social benefits. So we recommend and sell the " dragon " brand products, not simply in order to business interests, but we consider is that users in the use of "Longxing " brand products, we must continue to lower the cost and increase benefit.
Long-term since some domestic cement industry, power plant, especially in iron ore and non-ferrous metal mining industry and forged steel ball low chrome balls as a grinding body is still widely used. Although some domestic steel manufacturers use to replace Gao Gezhu ball low chrome balls and forging ball using made a lot of work, but because of its product quality but not hard, good wear resistance, sometimes even a large number of broken and so on, anyhow is cost-effective worse, therefore cannot bring economic benefits to users, so has the failed to change the status quo.
The mill industrial condition relatively abominable mines and thermal power energy industry with strong resistance to replace Gao Gezhu ball low chrome cast ball and forged steel ball in the country although is a revolution, but the enterprise wants to develop must constantly improve product quality, continuous underground to reduce production cost, to achieve high efficiency, the author thinks Gao Gezhu ball replaces low chrome cast ball and forged steel ball to use must be a trend. Foreign mining enterprises are already using high chromium alloy cast balls as a grinding body. According to the products of our factory for many years in the market to use feedback information and foreign mining user to use some successful experience, I plant researchers have recently developed a good wear resistance, strong shock resistance, strong corrosion resistance of mine for Gao Geqiu ( also suitable for cement industry). The products through scientific and reasonable match of chemical compositions and heat treatment process parameters optimization, the product after tempering hardness ( HRC) can reach 60-66, impact value is greater than or equal to 4J / cm 2, GB 3.5 meters height falling ball test machine impact fatigue test of the single ball more than 18000 times or more times, and scientific research personnel using dynamic load abrasive wear testing machine repeatedly detecting the products show a traditional high and low chrome cast ball incomparable high wear resistance and wear resistance of low chromium ball is 2 times more than the traditional Gao Geqiu hardness ( HRC in about 56, shock value is more than 2.5J / cm 2, GB 3.5 meters height falling ball test machine impact fatigue test of single ball number only about 8000 times ). The product of the quality indicators have been in the world with the industry's leading position, the current domestic steel ball field alone.
The Gao Geqiu is the most important characteristic of the chemical composition of matching on the trace alloying ( by adding a variety of alloy grain refinement ), and introduced the world's most advanced anhydrous resin sand molding, hot metal temperature casting and quenching heat treatment process ( production line automation control ), excellent product performance. The Gao Geqiu lower hardness chromium ball increases at least more than HRC15, wear-resisting performance is greatly improved, customers can bring more economic benefits. (1 ) as the product hardness HRC = 60 above, which have good wear resistance ; (2 ) impact value is greater than or equal to 3.5J / cm 2 above, but also has good impact resistance capacity, crushing rate is extremely low; (3 ) together with the Gao Geqiu of alloying treatment of its microstructure refinement, grain size analysis each cubic millimeter of the grain number to achieve 4-5 million, with strong acid and alkali corrosion corrosion ability is quite strong. Therefore, good resistance to abrasion wear low, high grinding efficiency, grinding machine ball gradation is stable and is not easy to change, not only in a certain extent increase the fineness of slag, improve the output table, but also ensure the ore quality. At the same time add ball cycle, greatly reduces the labor intensity of workers, especially greatly reduces the additional number of balls.
The new products have been in Philippines for Rex mine trial one success, the mines provided the ball using report shows wear significantly below the mine to use in other similar manufacturers Gao Geqiu (India VEGA) ; domestic Henan in Wugang Mining Development Company Limited, Inner Mongolia Chang Bo mining companies are now using this Gao Geqiu abrasion is approximately equal to the original low chromium ball 2 times; if you choose to use the " dragon " brand products please contact us, I plant strong technical strength is to provide quality assurance, with the majority of domestic and foreign customers, we always adhere to customer first, service-oriented principle, the best products to the most preferential prices to recommend to customers, make the greatest efforts to create customer benefits.
Most of the mines are generally low chrome ball, the price of about 6000 yuan / tons, tons of ore concentrate powder consumption of grinding body about 3Kg. If I plant the general Gao Geqiu ZQCr10, average price by 8000 yuan / ton ( excluding freight and packaging costs, the same as below ), tons of ore concentrate powder consumption according to 1.5Kg / T, according to the mine produced 100000 tons of ore powder, with Gao Geqiu replaced low chrome balls this unit actual amount will be big ball drop ball, then save part is the direct benefit, freight is reduced stage production increase part will produce greater benefit.
1, wearing that brought down the purchasing cost reduction : the original low chromium ball wear 3Kg tons of powder, the price 6000 yuan / tons, the production of 100000 tons of ore powder 300 tons of low chrome balls worth a total of 180 Wan Yuan; now with Gao Geqiu, wearing 1.5Kg, price 8000 yuan / tons, the production of 100000 tons of ore powder 150 t. Gao Geqiu, worth a total of 120 Wan Yuan. Two save 60 Wan Yuan. At the same time as the purchase quantity is reduced greatly, but also save a large sum of freight.
2, from the customer production workshop in the use of perspective, the use of ZQCr12 general Gao Geqiu, reflected in the tons of ore concentrate powder consumption cost is 8000 yuan / ton x 1.5 kilograms / ton? Concentrate powder = 12 yuan, and the use of ZQCr2 low chrome balls, reflected in the tons of mining ball consumption cost is 6000 yuan / ton x 3 kg / ton? Concentrate = 18 yuan, tons of ore concentrate powder ball consumption cost reduction of 6 yuan, the production of 100000 tons of ore can save 60 of Wan Yuan, its economic benefit is very considerable.
3, because the Gao Geqiu matrix carbide dispersed arranged, (Cr, C) 7C3 carbide content is high, so the good wear resistance wear low, high grinding efficiency of the ball mill, grading is stable and is not easy to change, not only in a certain extent increase the fineness increase production to Taiwan, guarantee and improve the ore powder quality, while extending the ball feeding cycle, reduces the labor intensity of workers.
4, intuitively tons of steel procurement costs 2000 yuan, virtually by ball consumption, compared to the price you can see the actual ball price:
(1500 g / T x 8000 yuan / ton ) / 3000 g / T = 4000 yuan / ton; that is to say to use licensing Gao Geqiu ZQCr12 actual steel price is 4000 yuan, wear reduction reflects the price is reduced 60004000 = 2000 yuan per ton. In conclusion, I plant strong technical strength is to provide quality assurance. In the vast majority of customers at home and abroad, we always adhere to customer first, service-oriented principle, to the best products at preferential prices to recommend to customers, make the greatest efforts to create customer benefits. We firmly believe that as long as both sides of supply and demand sincere cooperation, will certainly be able to win each other.
