Product Introduction

For the production of blast furnace, the Blast-furnace Plug not only directly affects the normal production of the blast furnace, but also relates to the service life of the hearth. Good injection material, good opening, good sintering, short plugging time, no moisture, corrosion resistance, anti-scouring, stable iron running is the basic requirement for the Blast-furnace Plug.

Features

1.Good plasticity and sintering properties. 2.Corrosion-resistant, anti-scouring. 3.No harmful substances during usage.

Application

It is mainly used in the blast furnace.
