Stainless Steel Anchor

A stainless steel anchor is a structural component. It connects and fixes lightweight refractory materials to the metal siding of the furnace. It also fixes integrated thermal insulation board and integrated board. The anchor increases the force area of the screw, which makes the board and the wall stronger.

Topower makes the anchor in Shandong, China. We select the structure and the material for each order from three inputs: the structure of the industrial furnace, the temperature of the furnace, and the surrounding environment. That is why we supply the anchor in several shapes and two steel grades instead of one fixed part.

Our product list covers Pin, Washer, Insultwist Stud, and Anchor Bolt, plus V-anchor, Y-anchor, and U-anchor forms. Each shape does a different holding job on a lining.

A pin holds a ceramic fiber module. Module grades run from STD to PC, up to 1600°C specification temperature. A washer spreads load under a fastener. A V-anchor, Y-anchor, or U-anchor wraps around or hooks into a board or a casting.

Ceramic fiber board covers 1000°C to 1550°C working temperature. Straight, cross, and L types cover the common fixing patterns.

Selection starts before the part is made. We look at how the lining is built, what holds the module or the board, and where the hot face sits.

Grade selection comes first, and it starts from the composition. The technical criteria on this page name it. 0Cr18Ni9 is 18% chromium and 9% nickel, which is why it holds an application temperature of 870°C. Cr25Ni20 is 25% chromium and 20% nickel, which is why it holds 1035°C. The extra chromium and nickel buys the extra 165°C.

Forming follows the shape. Rod forms are cut to length and bent. The V, Y and U shapes close on themselves, so they take a weld. On a lining, that weld is a load point, not a finish detail. It carries the weight of the module or the board.

After forming, the part is cleaned before it is packed.

We supply stainless steel anchor in SS304 and SS310. Choose the grade by application temperature and classification temperature. SS304 runs to an application temperature of 870°C and a classification temperature of 1260°C. The technical criterion for that grade is 0Cr18Ni9.

SS310 runs to an application temperature of 1035°C and a classification temperature of 1400°C. Its technical criterion is Cr25Ni20.

If your furnace runs hot and the anchor sits in the hot zone, SS310 is the grade that carries the higher numbers. If the anchor sits in a cooler zone, SS304 covers the job.

The stated suitable temperature range for our anchor products is 800°C to 1400°C. Stay inside the range of the grade you pick.

Send the furnace temperature, the anchor position, and the lining type, and we will match the grade and the form to that build.

We list our forms under one product group: Pin, Washer, Insultwist Stud, and Anchor Bolt, plus V-anchor, Y-anchor, and U-anchor.

The right dimensions follow the lining, not a catalogue page. Rod diameter, length, and hook size are set by the lining thickness and by the load the anchor carries.

Custom work is standard. Send a drawing with the furnace structure and the anchor position, and we will confirm the form, the grade, and the packing before the order.

We pack the anchors in wooden boxes, and the minimum order is 100 pieces.

We load the packed anchors at our factory and ship on the terms agreed in the quotation. Send your destination country and port with the inquiry, and we will include the delivery terms in the quotation.

These anchor bolts are used in these areas:

• Fixing of ceramic fiber modules
• Fixing of various refractory bricks and castables
• Anchoring devices for fiber spraying
• Fixed connection of various high-temperature boards and equipment

In a module or a board lining, the anchor ties the insulation layer back to the steel shell. The layer stays in place as the furnace heats and cools. In a castable lining, the same anchor holds the refractory to the shell. Low cement castable grades cover application limits from 1580°C to 1800°C.

Brick linings use the same anchor to hold the brickwork to the shell. The common choice is SK33 or SK34 fireclay brick. For fiber spraying, the anchor gives the sprayed layer something to grip. Where wear is heavy, high alumina castable runs from 45% to 80% Al2O3.

In every case the anchor keeps the light refractory material tied to the furnace siding. Send the furnace structure, the lining type, and the anchor position, and we will match the form and the grade to your build.

Is the stainless anchor the same as a stainless anchor bolt?
In our product list they sit in the same anchor group. The group covers Pin, Washer, Insultwist Stud, and Anchor Bolt, plus V-anchor, Y-anchor, and U-anchor. Send the drawing and we will confirm the exact form.

What does the anchor do?
It is a structural component. It connects and fixes lightweight refractory materials to the metal siding of the furnace, fixes integrated thermal insulation board and integrated board, and raises the force area of the screw.

What is the difference between SS304 and SS310?
SS304 has an application temperature of 870°C, a classification temperature of 1260°C, and the technical criterion 0Cr18Ni9. SS310 has an application temperature of 1035°C, a classification temperature of 1400°C, and the technical criterion Cr25Ni20.

Which anchor shapes do you supply?
Pin, Washer, Insultwist Stud, and Anchor Bolt, plus V-anchor, Y-anchor, and U-anchor. The general shapes are straight type, cross type, and L type.

Can I get a sample, a price, or a small order?
Yes. Minimum order is 100 pieces. Send your anchor form, material, application temperature, quantity, and drawings. We will return a quotation with the price and the delivery terms.

How are the anchors packed?
They are packed in wooden boxes. Send your form and quantity and we will confirm the packing plan before shipment.
