GENERAL SPECIFICATIONSARC STUD WELDED ANCHORS

ARC STUD WELDED REFRACTORY ANCHORSMATERIAL: Standard in low carbon steel and 302/304/305 stainless. Monel, inconel, and

other grades of stainless steel are available.PLATING: Plating is not standard. Cadmium to ASTM A 165, type TS and zinc to ASTM

B 633 are available. Non-weldable plating is removed from the weld end toavoid contamination of the weld.

ANNEALING: Low carbon steel can be annealed to a maximum of 75 Rockwell B and stainlesssteel to a maximum of 90 Rockwell B.

WELD BASE: Solid flux is provided where required.

DESIGNING WITH SUNBELT ARC STUDWELDED REFRACTORY ANCHORS:

Advantages: SUNBELT arc stud weldedrefractory anchors reduce costs and downtime andincrease production through speedier installationand improved product quality. Arc stud weldingsystems are portable and require minimalinstruction or maintenance for use. Speed ofanchor application and ease of use reduce laborrequirements and eliminate other complicatedfastening systems while maintaining excellent weldquality and improved refractory holding power.

The temperatures indicated are those encounteredin continuous service. Slightly higher temperaturescan be withstood if the fluctuation is cyclic innature. For applications above 2500 F, theanchors can be made of inconel or other specialmetals.

HOW TO APPLY THE REFRACTORY ANCHORANCHOR LENGTH & SPACING: All information given in this section is general and mayvary according to special service conditions encountered. Therefore, this information should onlybe used as a guide. The anchor length shown is the after-weld length of the longest section of theanchor. The lengths (in table #3) are recommended to insure good refractory holding power, whilepreventing rapid oxidation of the anchor and preventing spalling of the refractory surface.Generally the anchor length should be about 75% of the refractory depth, however, the end of theanchor should never be closer to the refractory hot face than 1. The anchor spacing will bedetermined by the type and density of the refractory used, and how and where it is to be applied.For anchoring purposes, the refractory can be classified as LOW DENSITY (25-90 lbs. per cu. Ft.)and HIGH DENSITY (100-200 lbs. per cu. Ft.). High-density material can be used in onecomponent linings of any thickness. Low-density material is only used in one component linings toa depth of 6. Frequently, in sections more than 6 thick, high-density material composes theworking lining with a back up of low-density material.

REFRACTORY ANCHORS:ANCHOR PATTERNS

ANCHOR PATTERNS

The three anchor patterns (shown below) are in use today; the latter two being the more popular.The important factor is that an irregular pattern is achieved by opposing anchors so that secureretention of the refractory in all directions is achieved.

NOTE:The expansion of the steel anchor is usually greater than that of the refractory material,especially in dense, high strength castables. Metallic refractory anchors can be coated withvarious materials that will burn off and allow room for the anchor to expand

Consult your refractory supplier for the proper refractory and coating material to meet yourapplication needs.
