Ceramic fiber fabric for Howrah foundry and furnace insulation
Most Howrah foundries melt in cupolas, while about one in ten runs an induction furnace for ductile iron and steel. That difference decides the cloth: a cupola screen wants stainless reinforcement for strength, while a wrap near an induction coil must carry no metal at all. We make both Signature builds, from 1.5 mm to 6.0 mm, cut them to your length × width at our Ahmedabad factory and dispatch them to your unit.
For furnace covers that are lifted every heat
Graphite Coated Ceramic Fabric DSZGCF3.0 has a sealed black face on both sides, so a door or lid cover that is handled every charge wears more slowly and sheds fewer fibres.
Cupola or induction: choose the build first
Before thickness, decide whether the cloth may carry steel. In a cupola shop the reinforcement is an advantage. Beside an induction coil it is a problem.
| Attribute | SS reinforced | Non-metallic |
|---|---|---|
| Models | DSZCF1.5, 2.0, 3.0, 3.0P, 4.0, 5.0 and 6.0 | DSZCF3.0NM only |
| Thickness and weight | 1.5 mm to 6.0 mm, 800 to 3500 GSM | 3.0 mm, 1000 GSM |
| Listed temperature | 1000 °C to 1760 °C (1.5 and 2.0 mm); 1260 °C to 1760 °C (3.0 mm and up) | 1260 °C to 1760 °C |
| What the build gives you | Stainless strands in the yarn add body and tear resistance when the cloth is pulled tight or moved | Plain ceramic cloth with no metal to conduct, heat up or mark the surface |
| Typical Howrah job | Cupola tapping screens, ladle-area barriers, furnace-door and lid wraps | Wraps and covers near induction coils, busbars and furnace panels |
Howrah foundry localities and the cloth to start with
Howrah's foundry cluster, around 320 units across the river from Kolkata, is concentrated in a handful of localities, with newer units in organised parks further out in the district. The furnace each area runs decides where to start.
| Area | Furnace work there | Start with | Order |
|---|---|---|---|
| Liluah and BelgachiaFoundry and steel re-rolling localities | Cupola melting for grey-iron castings, plus reheating furnaces in the Liluah re-rolling mills. Screens at the tapping spout and wraps on furnace doors take radiant heat and get pushed aside many times a shift. | DSZCF4.0 or DSZCF5.0 | |
| Salkia and Benaras RoadCupola foundry belt, north Howrah | Cupola foundries casting the cluster's typical sanitary, pump-body and machinery work. Lining repairs between melts need insulating covers over the cupola shell and spout while the crew works. | DSZCF3.0P or DSZCF4.0 | |
| Dasnagar and BalitikuriFoundries beside engineering units | Foundries working next to engineering units. Where a unit melts ductile iron or steel in an induction furnace, cloth near the coil, panels or busbars should carry no steel. | DSZCF3.0NM near the coil; DSZCF3.0 elsewhere | |
| Jangalpur and SantragachiFoundry localities, south Howrah | Repeat casting runs, with annealing furnaces used for finishing across the cluster. Door seals and lid wraps are opened every charge, so the cloth face wears before the heat damages it. | DSZGCF3.0 or DSZCF3.0P | |
| Foundry Park, Ranihati–Amta RoadOrganised foundry park, Howrah district | New and expanding melt shops. Commissioning a furnace calls for a mix of thicknesses at once: thin cloth for small fittings and heavy cloth for fixed barriers. | DSZCF2.0 to DSZCF6.0 on one order | |
| Uluberia Industrial ParkWBIIDC industrial park, Howrah district | Iron and steel casting alongside engineering and fabrication. Heat-treatment and pre-heat wraps on fabricated parts, and fixed barriers near furnaces during plant maintenance. | DSZCF3.0; DSZCF6.0 for fixed barriers |
Thickness, weight and listed temperature by model
With the build chosen, pick the thickness. More millimetres and GSM put more insulating mass between the heat and what sits behind the cloth. Note that the two thinnest builds start at a lower listed temperature. For how to read these ranges, see our guide to temperature ratings.
| Model | Thickness | Weight | Build | Reference roll | Listed temperature | Order |
|---|---|---|---|---|---|---|
| DSZCF1.5 | 1.5 mm | 800 GSM | SS metallic reinforced | 1 × 30 m | 1000 °C to 1760 °C | |
| DSZCF2.0 | 2.0 mm | 950 GSM | SS metallic reinforced | 1 × 30 m | 1000 °C to 1760 °C | |
| DSZCF3.0 | 3.0 mm | 1000 GSM | SS metallic reinforced | 1 × 30 m | 1260 °C to 1760 °C | |
| DSZCF3.0P | 3.0 mm | 1500 GSM | SS metallic reinforced | 1 × 30 m | 1260 °C to 1760 °C | |
| DSZCF3.0NM | 3.0 mm | 1000 GSM | Non-metallic ceramic cloth | 1 × 30 m | 1260 °C to 1760 °C | |
| DSZCF4.0 | 4.0 mm | 1800 GSM | SS metallic reinforced | 1 × 30 m | 1260 °C to 1760 °C | |
| DSZCF5.0 | 5.0 mm | 2500 GSM | SS metallic reinforced | 1 × 30 m | 1260 °C to 1760 °C | |
| DSZCF6.0 | 6.0 mm | 3500 GSM | SS metallic reinforced | 1 × 20 m | 1260 °C to 1760 °C | |
| DSZGCF3.0 | 3.0 mm | 1000 GSM | Graphite coated both sides, black | 1 × 30 m | 1260 °C to 1760 °C |
The three 3.0 mm builds differ in how they are made, not in thickness. DSZCF3.0P is denser at 1500 GSM, DSZCF3.0NM has no steel, and DSZGCF3.0 is graphite coated. All DSZCF cloth is white; the reference rolls are formats, not minimum orders.
Ceramic or fiberglass for your furnace?
Not every furnace job in a foundry needs ceramic fibre. Check the working temperature first, then pick the material.
- Ceramic fiber fabric fits when
- The cloth sits close to molten metal, a cupola spout or a furnace opening, where glass or silica cloth would be out of its range. That is the job DSZCF and DSZGCF cloth are made for.
- Compare with fiberglass when
- The furnace runs at a modest temperature, as many annealing and stress-relief furnaces do. Read the furnace's real working temperature against each material's listed range before you pay for ceramic.
Our fiberglass vs ceramic fiber guide compares the two materials job by job.

Frequently asked questions
Answers for Howrah and Kolkata foundry, furnace and maintenance buyers ordering Signature ceramic fiber fabric.
Which ceramic cloth should hang beside a cupola tapping spout in a Howrah foundry?
A heavier SS metallic reinforced build. DSZCF4.0 (4.0 mm, 1800 GSM) and DSZCF5.0 (5.0 mm, 2500 GSM) are listed at 1260 °C to 1760 °C and keep their shape when a screen is pushed aside at every tap. For a screen bolted in place that rarely moves, DSZCF6.0 (6.0 mm, 3500 GSM) puts the most mass between the spout and the floor behind it.
Our unit melts in an induction furnace. Which build is safe to use near the coil?
DSZCF3.0NM. It is plain ceramic cloth with no stainless steel in the weave, at the same 3.0 mm and 1000 GSM as DSZCF3.0 and the same listed 1260 °C to 1760 °C. Every other DSZCF model carries SS reinforcement, so keep those away from the coil and live electrical parts.
Do I need ceramic fiber fabric for an annealing furnace, or will fiberglass do?
Check the furnace's real working temperature first. Ceramic fiber fabric is meant for duty where glass or silica cloth is out of range. If your annealing furnace runs well inside a fiberglass cloth's listed range, fiberglass may be the more economical choice. Our fiberglass vs ceramic fiber guide sets the two side by side.
Why are DSZCF1.5 and DSZCF2.0 listed differently from the 3.0 mm cloths?
The two thin builds are listed at 1000 °C to 1760 °C. DSZCF3.0 and every thicker model are listed at 1260 °C to 1760 °C. When a furnace job sits between 1000 °C and 1260 °C, specify 3.0 mm or thicker instead of relying on the thin cloth, and confirm the range on the variant you pick on the product page.
Our 3.0 mm furnace-door wrap keeps wearing through. What should we try?
DSZCF3.0P. It stays at 3.0 mm, so it still fits the same door frame or clamp, but it weighs 1500 GSM against 1000 GSM on the standard DSZCF3.0. That gives a denser cloth without stepping up to the 4.0 mm build.
When is the black graphite-coated fabric worth it on a foundry floor?
When the same cover is lifted, dragged or refitted every heat. Signature Graphite Coated Ceramic Fabric DSZGCF3.0 is 3.0 mm and 1000 GSM, graphite coated on both sides and listed at 1260 °C to 1760 °C. The sealed face resists rubbing and sheds fewer fibres than the white cloth. For insulation that is fitted once and left alone, the uncoated DSZCF cloth is enough.
We are replacing old asbestos cloth on furnace doors. Is this a direct swap?
Ceramic fibre is the usual non-asbestos replacement for asbestos cloth in furnace and foundry work, and Signature Ceramic Fiber Fabric contains no asbestos. Match the thickness to the old cloth and check the listed temperature for the door. Handle and cut it under your site procedure for ceramic fibre, since it is still a high-temperature mineral fibre.
How do we order the fabric in the sizes our furnaces need?
It is sold by the square metre. On the product page, choose the model and enter the length and width in metres, and the fabric is cut to that size. The 1 × 30 m roll (1 × 20 m for DSZCF6.0) is only a reference format. For several furnaces, list each piece as its own model and size line.
Can ceramic rope and tape for door seals go on the same quotation?
Yes. Signature Ceramic Fiber Rope (DSZCRP, 6 mm to 50 mm, round or square, sold per kg) and Signature Ceramic Fiber Tape (DSZCTP, 3 mm and 5 mm sections, sold per kg) can be quoted with the fabric. Put each item on its own line with the size or diameter and the quantity.
Do you have a branch or stock in Kolkata or Howrah?
No. Darshan Safety Zone, an ISO 9001:2015 certified manufacturer, makes Signature ceramic fiber fabric at our factory in Ahmedabad, Gujarat, and dispatches it to the unit address on your order in Howrah, Kolkata or elsewhere in West Bengal. The quotation confirms dispatch for your models and quantities.
Relining a cupola or refitting furnace doors in Howrah?
Send the furnace type, the build, each piece's length × width and the date you need it. We will quote fabric and seals together from our Ahmedabad factory.
