Baoji Huaguang Casting Material Science and Technology Co.,Ltd
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.
