Tundish Suppliers and Manufacturers

Tundish powder Tundish flux or powder provides multiple functions. Firstly it insulates the molten steel both thermally (preventing excessive heat loss) and chemically (preventing air entrainment & reoxidation). The quality of the flux being used also play vital role, such as nitrogen pick-up was reported to be reduced from 16ppm to 5ppm, from ladle to mould by changing tundish flux with lower SiO2 content, in one of South American steel works. Secondly, in ideal circumstances, the flux also absorbs inclusions to provide additional steel refining.

1. Material: stabilized zirconia, zircon sand, alumina, graphite, aluminum phosphate monobasic acid prime wood. 2. The structural principle: the tundish nozzle is a combination of inner core and exterior. The inner core is made of stabilized zirconia and zircon sand, producing through molding machines and high-temperature calcination. The exterior is made of zirconium and corundum, producing through molding machines and low-temperature baking. Tundish nozzle is located at the bottom of the tundish, it's the channel of liquid steel to flow from the tundish into the crystallizer. 3. Function of the tundish nozzle 1). Convey molten steel; 2). Control the flow rate of molten steel. Tundish nozzle is an important component of continuous casting. Through the tundish nozzle, the molten steel flows from the tundish into the crystallizer. During this process, the outlet aperture will be eroded and widened, the amount of molten steel per unit of time increases and the surface of molten steel in the crystallizer rises, which requires increasing casting speed to digest the excess molten steel. With the further erode and widen of outlet aperture, adjusting casting speed can not digest all the excess molten steel, then releasing the excess molten steel through the mouth of the emergency is adopted though it's a waste of steel enterprises. Therefore, whether the outlet aperture of tundish nozzle remains constant is a most important measure of the quality. Usually, it is measured through the total use time in actual production. Our tundish nozzle has the properties of high refractoriness, good resistance to erosion, and can bear rushing scour etc. Our customer included new shalimar, shalimar, murtza, punjab.

We, Imperial World Trade are supplying an extensive assortment of tundish nozzles which is mainly made up of paper, and non-swirling type nozzles etc. They are formed to achieve the highest corrosion and thermal shock immunity at high heat. They are produced from zircon containing ZRO2 65% to 95% and alumina-carbon matter to accommodate casting requirements. They are proper for a single as well as series of heats.

We, Imperial World Trade production is of top position Tundish Boards in the leading market. Tundish Boards are the excessive boards utilized to form an inner lining for constant casting tundishes. Our Tundish Boards help in conserving energy significantly and also diminish destruction of refractory in tundishes. The Tundish Boards also develops the quality of steel by producing fresh board lining whenever the tundish is changed.

Tundish Dry Vibration Mix 1. Preparation before construction (1) Check whether the gas, compressed air and industrial electricity are normal, whether there is leakage, and whether all valves are completely closed. (2) Check if all kinds of control instruments and vibration motors are working properly. (3) Check whether the raw material has agglomeration. If there is serious agglomeration, it should not be used; if there is a small amount of agglomeration, the agglomerate should be crushed before use, or discarded. (4) The residue of the permanent lining surface of the tundish, residual steel and other debris must be removed. (5) If there is a crack of â?¥3mm in the permanent lining of the tundish, it must be repaired first, and the repairing material must be dried before construction. (6) Evenly apply 2~3mm release agent (or waste engine oil + graphite) on the working lining tire.

We also have rich expertise in successfully handling the emerging requirements of Ladle Covering Compound Radex . These find usage as ladle and tundish covering compounds and have in them high insulating power along with good expandability as well as spread-ability. It instantly spreads to cover entire molten steel surface in ladle and tundish and helps in significantly reducing heat loss that occurs due to radiation from top surface of liquid steel. Further, it also helps in maintaining consistent temperature in ladle as well as in preventing temperature drop as well as freezing of metal in longer duration casting processes.

Calcium aluminate advantages: 1) Uniform chemical compositions, low melting point, high melting speed, and short smelting time; 2) It has no fluoride and doesnt erode furnace lining and ladle, and it is compact, non-absorbent,and easy to storage as well; 3) Stable phase and fast dust-reducing speed, rapid desulfurization effect stabilized at 60%, and suppresses phosphorus into molten steel; 4) Improving the protective effect and reducing erosion to ladle lining.
