SiO2 Siliceous Flow Guiding Sand Refractories For Steel Making Molten Steel Erosion Resistance

SiO2 Siliceous Flow guiding sand Good fluidity refractory for Ladle

The flow guiding sand is divided into various series of products such as chrome, zirconium and siliceous, and the products suitable for production are selected according to the different conditions of each steel plant.

Flow guiding sand is a kind of bulk refractory material filled in the ladle block brick and the upper nozzle. It has good fluidity, chemical stability, moderate grain size, good compaction and high temperature performance, and its quality greatly restricts the level of automatic pouring rate of ladle.

Advantages of siliceous flow guiding sand for ladle:

1. It has the advantages of good fluidity, large specific gravity and fast speed.

2. Strong resistance to molten steel erosion.

3. High refractoriness, easy to produce mild sintering with molten steel, without blocked.

Notice:

(1) The flow guiding sand is in a high temperature state for a long time in the ladle nozzle, so the sintered layer is required to have high refractoriness.

(2) After the flow guiding sand is filled into the nozzle, it is directly in contact with the molten steel, and the initial sintering temperature should not be too high to avoid the accident caused by the floating of flow guiding sand when adding molten steel.

(3) During the use process, the flow guiding sand is subjected to a large static pressure of molten steel. In order to prevent the material from

being stretched, the flow guiding sand is required to have very good fluidity, and the friction between the particles is as small as possible.

(4) At high temperature, the flow guiding sand should be prevented from falling automatically or unable to effectively support the upper material during the process of use.

(5) In the high temperature and long-term smelting state, the liquid surface can not be sintered too thick in order to achieve automatic pouring, improve production efficiency, reduce molten steel pollution, reduce flue gas consumption and improve production safety factor.

Jundao (Henan) New Materials Co.,Ltd（For short: JDNRCO） was registered in April 2006 at Yuecun Town，Xinmi City, Henan Province of People’s Republic of China, one of the key enterprises in refractory materials in China. Using refractoriness as the main raw material, JDNRCO produces fireclay、high-Al、corundum、mullite series of high load、low creep、high density、low porosity refractory bricks, series of light weight insulation、high crushing strength、acid and alkali resistant refractory materials. The products are mainly used in Non-ferrous metal industry, Steel industry, Metallurgical industry, Building industry, Power industry and other industries….

The company purchased a large number of advanced and international testing equipment to research new materials and test products quality, which promoted all of product to meet the design requirements. After having designed and built the gas tunnel kiln with environmental friendly and fully automatic controlled high temperature, JDNRCO got a comprehensive annual output of 70,000 tons of high quality refractory capacity, and had been assessed as conforming to meet the requirements of GB/T19001-2016/ISO 9001：2015, which promoted the sustainable development of company.

There is one professional technical team, the main managers in different divisions of the company are all have the corresponding senior or middle professional titles. They have professional ability to communicate with customers timely and can handle with customers’ demands effectively. Also there are specialists who are responsible for the customers’ after-sales work.

Nowadays, JDNRCO has long-term cooperation with large state-owned enterprises, such as Chalieco, NFC, Sinosteel etc. In addition, JDNRCO actively develops the international market, and has exported to Southeast Asia, the Middle East and other foreign countries’ large-scale projects, such as Indian Bharat Alumina Co.,Ltd, Iran Alumina company etc, which has improved the corporate reputation.
