Introduction

The product is a high-tech product developed by our factory in 1987, which is characterized by low creep, high refractoriness under load and high thermal strength. Having passed the technical evaluation organized the former Ministry of Metallurgy in 1989, the products filled up a domestic gap function as the substitutes for the imported products of the same kind.
