Shotcrete for Blast Furnaces

Minteq’s strategy to reduce the cost per ton of iron and increase the life of the blast furnace is enabled by our world class shotcrete products. These products offer the following functional benefits:

  • Rapid installation rates to reduce total refractory installation time
  • Low rebound to reduce total consumption
  • Superior refractoriness that increases furnace life, and improves fuel efficiency

For Blast Furnace operations we would like to highlight the following SUPERSHOT™ products:


  • Ideal material for mid-  to upper-stack re-linings and repairs
  • Excellent abrasion resistance at lower temperatures
  • 60 percent alumina silica containing, low cement bonded shotcrete
  • This binding system does not require high-firing temperatures to develop physical properties and abrasion resistance


  • 72% alumina, 15% silicon carbine containing, ultra-low cement binder
  • High density, high thermal conductivity, low porosity shotcrete
  • Capable of rapid dry out requirements


  • Shotcrete material for thermal protection of Bosh lining during blow-in
  • Value by using the same shotcrete equipment, with no change over to gunning material and batch guns
  • Rapid installation rate of +8 tons/hour

Shotcrete Refractories Introduction

Minteq International Inc. (Minteq) is the leader in shotcrete technology for all industries we serve. Our standing comes from a fundamental, and universal, goal: extending the life of the refractory lining. Whether the specific mission at hand involves a new furnace, vessel re-lining, cold repair, or hot maintenance, we pride ourselves on finding a solution for every customer. This customer-based focus has led to the development of many new applications and products over the past five years.


Presently, we sell alumina-silica, magnesia, spinel, silicon carbide, and AZS-based refractory shotcretes to the following industries, for the following applications:

  • Iron & Steel: blast furnaces, torpedo cars, iron ladles, BOF Converters, steel ladles, vacuum degassers, and tundish
  • Aluminum: melting and holding furnaces
  • Cement & Lime: pre-heaters, risers, dams, inlets, rotary kilns, nose-rings, coolers
  • Power Generation & Incineration: cyclone burners and ash hoppers

Minteq’s world-renowned OPTISHOT®, DURACRETE™, SUPER SHOT™, FASTFIRE™, and HOTCRETE® refractory mix materials are offered in a wide range of specific applications and can be customized to your unique refractory requirements.
