Zircon Sand High Fire Resistance For Investment Casting

High cost-effective Mullite and Bauxite Substitute Zircon Sand of Casting Sand for Investment Casting

1. Description:

Substitute Zircon Sand of Casting Sand is made of Mullite and Bauxite,it's the new products of our company .

It is roughly the same as that of zircon sand, slightly lower than that of chromite sand, which is used as molding material.It can effectively prevent the casting from expanding defects.

The price of zircon sand is cheaper, about 1 / 3 of traditional zircon sand and 1 / 2 of chromite sand

Main properties of zircon sand:

a. The fire resistance is above 1750-1800 ℃, and the chemical stability at high temperature is much better than that of silica sand, which can be used for Cast steel, cast iron and various non-ferrous alloys.

b. It is an electric melting material with compact texture and better durability than sintered ceramsite.

c. After heating, the expansion rate is about 1 / 5 of that of silica sand, which is roughly the same as that of zircon sand, slightly lower than that of chromite sand, which is used as molding material.

2. Application:

a. Refractory raw materials: used for the production of zircon stone brick, staggered corundum electric melting brick, sintered brick, nozzle brick, glass furnace ramming material, castable

b. Ceramics: stable chemical properties, is a high-quality and cheap opacifier, widely used in the production of various building ceramics, sanitary ceramics, daily ceramics, first-class crafts ceramics, etc

In the processing and production of ceramic glaze, it has a wide range of application and measuring force

c. Glass: color picture tube in TV industry, emulsion glass in glass industry

d. Coating: good suspension stability, excellent thixotropy and fluidity, good brushing performance, no brush marks on the coating, low organic content, low gas generation, high coating strength.

e. Casting: it has the characteristics of good thermal conductivity, small thermal expansion, good thermal shock stability, high fire resistance, and large heat storage coefficient of zirconium sand.

Our mine company established in 2003,and its trade company ,Qingdao Jinjunxuan International Trade Co.,Ltd,founded in 2018, relying on the group's logistics advantages and rubber trade experience, Jinjunxuan international has been shouldering the responsibility of group logistics business development and model transformation since its establishment.

In 2019, In view of the fierce competition in the raw material market, we pay more attention to the quality of products and firmly believe in the concept of "quality-oriented, honest operation". We also rely on mine company technical advantage to develop customized products.

Using our product, the casting is easy to be shelled, not deformed, not easy to shrink, with good finish and high yield. After that, remind the customer not to be greedy for cheap choice of cheap sand so as not to affect the casting finished products.

It is recommended to choose the products of regular mullite manufacturers with reasonable price, quality and more guarantee. We hope that through our efforts and careful service, we can provide customers with cost-effective products and contribute to the development of the investment casting industry.
