Gu Chang-year foundry with the provisions of the factors you share gullies design should be considered: the mouth in the form of rain, mainly flat grate grate and vertical categories. Flat road smooth flow of rainwater grate grate, but susceptible to tree branches and other debris clogged storm highway stormwater grate production, affecting the ability to collect water. Li clogging highway stormwater grate grate much money, ditches need to maintain a certain depth, but some towns due to yearly maintenance of roads, as roads heightening, so stand grate area reduction, affecting the ability to collect water. Around can be determined according to the specific circumstances and experiences. Gu Chang foundry specializing in the production of all kinds of ductile iron covers the company, with annual production capacity of 5,000 tons, is being expanded with an annual output of 10,000 tons. Composite grate cold extrusion process of cold extrusion mixing short fiber pulp is added, stirring evenly, containing the stirred slurry was poured into the fiber by conventional mechanical i.e. bricks improved hopper of the extruder; The release agent is applied on the composite material grate cavity mold, and then the mixed slurry is extruded from the extruder, it fills the mold cavity, and then extruded. Curing 5 to 10 minutes to remove the finished product after extrusion. Was added in the formulation of short fibers, while use of an extruder to implement improvements, making it suitable for a slurry of magnesium extrusion mixing requirements, thereby beyond traditional molding process, so that a composite synthetic magnesite Grate greatly improved yield , and its strength, stiffness and impact resistance and other indicators are also increased accordingly. Gu Chang-year foundry founded in 2006, is a new modern and dynamic enterprises. Since the construction of ongoing efforts to grow, is to become a professional production of ductile iron covers the company, with annual production capacity of 5,000 tons, is being expanded with an annual output of 10,000 tons.
