We provide a complete package of monolithic refractories, insulating and safety backup lining materials and all accessory materials needed to line your furnace.  We provide unsurpassed support with in-house engineering and technical services, and on site installation and trouble shooting support. We recommend a fully engineered system designed to allow for even wear throughout the refractory lining.

Our complete package has allowed us to remain the leader in coreless furnace refractories in many major markets worldwide. Our promise is to "Be There Worldwide."

Primary Linings                                            Top of Page We provide more alternatives than any other manufacturer.  We have the products to fit your specific melting niche.  These come in a wide variety of compositions that incorporate alumina, silicon carbide, silica, fused silica and magnesia. Our traditional DRI-VIBES® include those with fused alumina and silicon carbide.  MINRO-AL® RAM A29 (copper), MINRO-AL® RAM A30 (brass), and DRI-VIBE® 250A (copper nickel) have been used for many years.   MINRO-SIL® RAM 1001 has also been used for more than 30 years in mild melting and holding applications.  DRI-VIBE® 390A (Mullite) is also widely used. In 1995 we introduced improved products designed to minimize cracking due to thermal shock.  The formulations include fused alumina, silicon carbide, and fused silica.  These products included DRI-VIBE® 351A (copper), DRI-VIBE®353A (brass), and DRI-VIBE® 350A (copper nickel). In 1995 we also introduced DRI-VIBE® 252A for large batch melting furnaces where increased expansion was needed.  We later introduced DRI-VIBE® 253A for higher temperature applications in large furnaces.  Both compositions include alumina, fused silica, and magnesia. In 1998 we introduced DRI-VIBE® 226A and DRI-VIBE® 227A.  These products contain 26% silicon carbide and are extremely non-wetting and abrasion resistant.  DRI-VIBE®401Z, silica plus zircon, was introduced as a more wear resistant silica formulation for all copper based alloys. We can also supply a variety of wet ram compositions.  MINRO-AL® WET RAM A32W, A33W, and A34W were widely used in the past, prior to adoption of DRI-VIBE® technology.  These compositions contain alumina and silicon carbide The important thing to understand is that we have a composition that will maximize your campaign life, regardless of your conditions.  And, if necessary, we will develop what you need to have.

Topcaps                                                  Top of Page These are generally high alumina DRI-VIBES® with high bond content to promote strength at low temperatures.  MINRO-AL® RAM A29 and  DRI-VIBE® 481A are commonly used.  MINRO-AL® PLASTICS and MINRO-AL® WET RAMS are also widely used.

Grouts                                                 Top of Page We offer the largest selection of silica and alumina grouts.  MINRO-SIL® GROUT S14 has been a standard for more than 30 years.  MINRO-SIL® GROUT S15 was recently developed for better workability. Our alumina grouts are unique.  These include colored grouts that allow the coil to be easily distinguished from the working lining during lining removal.  We also have grouts with non-ceramic fibers that allow for rapid dryout during grout heatup.  MINRO-AL® GROUT 263AF, MINRO-AL® GROUT 763AF, MINRO-AL® GROUT 563A, and MINRO-AL® GROUT 663A are a few of the grouts in our product offering.

Maintenance                                                 Top of Page We offer many materials including plastics, ramming compounds, and washes.  Our plastics range from 70% - 95% alumina and are manufactured in both fine grain and construction grade consistencies.  These plastics include MINRO-AL® PLASTIC A76, MINRO-AL® PLASTIC A85, MINRO-AL® PLASTIC A89, and MINRO-AL® PLASTIC A91.  We also have plaster versions of each when maximum workability is required.  Chrome alumina plastics provide maximum resistance to mechanical and chemical attack.  STEEL-PACK 90CR is the best chrome alumina refractory available.  Other chrome oxide products include SCOTT RAM MORTAR A96 and SCOTT RAM PLASTER A95.

Slip Plane Materials                                    Top of Page We provide a wide range of fiberglass cloth and mica products for your slip plane.  MINRO-WEAVE CLOTH is available in several dimensions.  It is also available in a heat treated or sintered form.  This product is easily cut and produces significantly fewer airborne fibers during installation. MINRO-MICA products include a wide variety of compositions and thickness'.

Foundry Floor                                           Top of Page MATRICAST TUFFLOOR is used for foundry floor applications.  This spall resistant, high strength castable can be installed quickly, and placed in service after 24 hours of air-drying.  It will improve safety and reduce floor maintenance in areas subject to molten metal splash, dross, and other intermittent high temperature exposures.

Other                                                           Top of Page We inventory a complete line of safety lining bricks, thermocouple wires, and everything else needed for your furnace.  We can also provide melt in forms, installation equipment, and everything else you require.

We want to be your one-stop supplier.
