Introduction
With the development of metallurgy technology,the conditions for tundish application become increasingly rigid and the requirements for refractory materials of tundish are correspondingly higher.Integral casting materials have apparently strengths in both construction and application so that they have been applied in more and more steel enterprise.
Application and characteristics
This product is fit for the integrated casting for tundish permanent lining.Permanent lining casting material manufactured by our company possesses superior characteristics such as low thermal conductivity(tundish wall temperature is no more than 100?漯span>), fine thermal stock stability,less prone to crack,easy to construct,compact structure,high strength and not stick to working layer.The service life can be up to 300 hours.
Package
Package??Package is done by use of composite bags(500kg),or under the customer's requirements.
Cautions
Rainwater proof and moisture proof for storage and transportation.The construction is not fit to be conducted in winter.
