        Introduction of Ceramsite(foundry sand) in Steel Foundry

        Ceramsite(foundry sand) can be used as the surface sand of large steel castings instead of chromite sand, which can prevent sand sticking and make it easier to clean the falling sand.

        The use of Ceramsite(foundry sand) in the thick surface hot spot and riser root of large-scale steel castings can effectively prevent metal penetration and sand sticking, and reduce the environmental pollution caused by dust in the production process of casting sand falling.

        The advantages of Ceramsite(foundry sand) in Steel Foundry

        1. It is a neutral material, which can be used as acid and alkali binders.

        2. Good recycling performance and high cost performance

        3. High fire resistance, easy to collapse

        4. High thermal conductivity, good stability, no cracking

        5. Wide applications.


        QA&QC

        We implement strict QA & QC system internally. We will test the raw materials that enter into our factory, and unqualified material will not be used. The finished products will be also tested before leaving our factory.


        FAQ

        Q1: Where is your main market?
        A: Southeastern Asia such as Japan, Korea etc. Europe such as German, France etc. North America such as America, Canada etc. Middle East such as KSA, Oman etc.

        Q2: How to get the free samples for test?
        A: Please confirm your expect performance for the final product, and leave us your contact information, our sales will contact with you and help you choose the best product.

        Q3: What are the advantages of ceramsite(foundry sand)?

        A: The thermal expansion coefficient is small, and its performance is comparable to zircon sand. When the sand is prepared with zircon sand, the casting will not produce expansion defects.

        Q4: What are the advantages of ceramsite(foundry sand) over quartz sand in casting?

        A: The roundness of ceramsite is better, so the finish of casting is better, small thermal expansion has great effect on the improvement of casting precision

        Q5: Why the Ceramsite(foundry sand) has a good prospect in lost foam casting?

        A: According to statistics, the annual loss of Ceramsite is less than 5%. Thus, the high cost caused by the high price of Ceramsite is directly reduced, and the production cost is greatly reduced. According to the foundry budget of Ceramsite, the increased cost of using Ceramsite can be recovered in 8-10 months. With its own performance advantages, Ceramsite has been well developed in various industries. It has been proved that Ceramsite has a broad prospect as a sand for EPC.

        Q6: Why you should choose ceramsite(foundry sand)?

        A: The thermal expansion coefficient is small, and its performance is comparable to zircon sand. When the sand is prepared with zircon sand, the casting will not produce expansion defects.

        Q7: Are you factory or trading company?
        A: We are manufacturer have over 10 years’ experience, this company build from our oversea sales department, we do hope to use our professional knowledge and warm service to help you save cost. And you are welcomed to visit our factory anytime.
