Casting Ceramic Sprue Tube product reference in refractory
material, ceramic molding process diversity enriches the gate design, metal
distribution more meticulous, reasonable. Casting Ceramic Sprue Tube high
refractoriness (greater than 1700 degrees), scouring resistance, easy to use,
straight pipe, elbow, reducer pipe, tee, 45, variable diameter gate between
arbitrary tape inside connection. Using ceramic tube, gating system will no
longer use coating or flow steel brick, can reduce the cost. The ceramic tube
runner has advantages of high refractoriness, erosion resistant, light and
practical, easy cutting, easy to use, save the cost, so it can improve the
quality of the casting and it is praised by the majority of users.

China's agricultural economic crop planting area has grown rapidly, but due to the lack of suitable machinery, traditional artificial irrigation, fertilization, and spraying methods are still widely used. Potted crops, bagged crops, and seedlings are also used for pots, bags, and trays. Equal restrictions, irrigation can not be uniform.
In addition, the nozzle of the ordinary sprinkler not only has low spray uniformity, but also has a large impact on crops, which is easy to damage young crops; the amount of spray cannot be adjusted, and it is difficult to spray fertilizer or medicine. Traditional artificial irrigation, fertilization and spraying methods not only cause waste of water, medicine and fertilizer, but also have high labor intensity and low production efficiency, which causes the ecological environment to deteriorate and the quality of agricultural products cannot be guaranteed. The cantilever self-propelled sprinkler developed by the Planning and Research Institute of the Ministry of Agriculture, which can be used in greenhouses and open fields, adopts computer programming control technology and has a high degree of automation control. The field production comparison test shows that it is 60.9% water saving and 60% labor saving than artificial irrigation; the price is 60% lower than the imported foreign similar products, and the input-output ratio is 1:6.6. Dalian Century Seedling Co., Ltd. said that their seedlings were irrigated with water guns in the past, the water volume is large and uneven; the matrix permeability is poor; the emergence rate is low; the plants are weak, the plant type is not neat;
Therefore, a lot of work to do the seedlings is needed, and the amount of seeds is also large. After using this new type of sprinkler, the humidity in the greenhouse is stable, the plants are tidy and vigorous, and they grow quickly without disease. Compared with imported foreign similar products, in addition to uniform spraying, it has more functions such as fertilization and remote control; it is more convenient to use; therefore, it is more cost-effective. The application of this machine in the Xijiao Biological Garden of Dalian increased the income of seedlings by more than 10%, and saved labor, water and medicine and fertilizer, and increased 300,000 yuan in one year.
Water-saving and efficient self-propelled sprinkler
The multi-functional small cantilever self-propelled sprinkler, which can be sprayed evenly, saves water and labor, and fertilizes (medicine) accurately, can be manually and remotely controlled. It has been successfully developed by the Planning and Research Institute of the Ministry of Agriculture. As a special technical research project for agricultural structural adjustment, the project has recently passed the acceptance of experts organized by the Ministry of Agriculture.
