Shanxi's giant tire import volume hit a record high
A few days ago, the author learned from the Shanxi Inspection and Quarantine Bureau that there have been 1,001 large-scale mining tires that have passed the inspection and inspection by the Bureau since this year, with a value of $35.235 million, an increase of 24.97% and 63.76% year-on-year respectively, both of which have reached historical highs.
Giant tires are important parts for open pit mines. They are mainly used on large-sized trucks and large-scale excavation machinery equipment, accounting for 20% to 30% of the total cost of mine transportation. It is understood that these giant mining tires are mainly imported from China Coal Pingyi Group Co., Ltd. The company is part of the China Coal Group and is a coal mining company with open pit mining. The mining area is located at the junction of Pinglu District and Lucheng District of Shengzhou City. At present, the company has three large-scale open-pit coal mines, three large-scale modern wells, six supporting coal washing plants, and three special railway lines. The degree of modernization is relatively high, and the production scale is among the highest in the country. The annual output of raw coal is stabilized at 100 million tons. the above.
In November last year, China Coal Pingyi Group Co., Ltd. East Open Coal Mine was completed and put into production. A large number of giant mine excavation equipment and mine transportation vehicles were added. The consumption of tires increased significantly. Therefore, the company has successively imported a large number of giant tires from Japan, the United States, Spain and Belarus. The Shanxi Bureau took measures to follow inspections and rapid inspections to enable the import of giant mining tires to be put into use in a timely manner to ensure the smooth operation of coal mining operations.
Casting Thickening Sprue Tube Mainly applied to lost foam casting, mold casting, the traditional sand mold casting, coated sand casting, casting methods, to improve castings quality, reduce scrap, improve the quality of reclaimed sand, reduce the work intensity, etc. In China belongs to the first, it will be casting sprue tube of a revolution.
The main advantages:
1, light weight, easy to operate. Paper tube runner weight is only 1/10 of the same type ceramic tube runner weight, convenient operation, reduce labor intensity of more than 70%.
2, easy to cut, no pollution. Little dust paper knife cutting, cutting, greatly improve the intensity of labor and the environment.
3, good sealing, reduce risk into the sand. Interface using the socket type, not easy dislocation, interface closely, to avoid the sand into the sprue, effectively reduce the casting sand inclusion defects.
4, not with liquid metal. When pouring not crack, not adhesion, slag resistance, erosion resistance. Refractoriness is as high as 1460 ℃ above, solved the sprue adhesion problem for a long time.
5, the intensity is high, is not easy to damage. Room temperature compressive strength of 18 mpa, after repeated experiments, dropped below 1.5 meters high, will not damage.
6, for the castings without increasing carbon, carburizing. Ensure the casting material and performance is not changed.
7 and improves the quality of reclaimed sand, reduce equipment wear and tear. Paper after casting sprue tube blank, carbide waste few, about 1/20 of the ceramic tube runner, and easy to peel, easy clean, avoid the pollution of gating pieces of sand, and solved the ceramic gating pieces of sand reclamation equipment wear and blocking sieve, prolonging the service life of equipment.
8, energy conservation and environmental protection. Paper sprue tube with organic fiber and refractory materials such as waste paper as raw materials. Using process does not produce pollution, waste can biodegrade, is a typical green environmental protection, energy-saving products.
