Hongso 18" Cast-Iron Plate Setter Conveggtor for 18" Kamado Grills — Heavy-Duty, 3-Leg Heat Deflector

Hongso 18" Plate Setter Conveggtor is a heavy‑duty cast‑iron heat deflector that converts 18" kamado grills into an efficient indirect‑heat oven for even cooking and crisp pizza crusts.

If you own a large Big Green Egg, an AKORN 18" kamado, or another 18" kamado-style grill, this plate setter acts as a thermal barrier between charcoal and food so you can roast, bake, and slow-cook with better temperature control. Built from high‑density cast iron and engineered with three supporting legs, the device stabilizes ceramic pizzas, roasts, and delicate foods while improving heat distribution across the cooking surface.

How does this plate setter improve heat distribution?

The Hongso conveggtor spreads heat more uniformly across the grill cavity by creating an insulated cooking zone above the coals. Cast iron stores and radiates heat, smoothing out hot spots that can char food unevenly.

• 18" diameter provides broad coverage for large kamado bowls.
• 3-leg design elevates the stone to allow air circulation and steady heat transfer.
• Cast‑iron mass absorbs peak heat and releases it evenly for consistent cooking.

Can I use it to bake pizza and other oven-style dishes?

Yes — the plate setter doubles as a pizza grilling stone and indirect-heat deflector, giving you a crisp base while protecting toppings from direct flame. It performs well for pizzas, bread, casseroles, and roasted vegetables when paired with the right temperature management.

• 18" pizza stone surface fits large pies and multiple smaller items.
• Durable cast iron produces attractive grill marks and a crisp crust.
• Recommended technique: preheat the stone and use steady, indirect heat for best results.

What maintenance and cleaning steps keep the plate setter lasting longer?

Cleaning is simple but important: avoid harsh detergents and mechanical abrasion that can remove the seasoned surface. Gentle soaking and soft brushing preserves the cast‑iron finish and extends the stone's life.

• Soak in hot water with mild detergent briefly, then scrub lightly with a soft brush.
• Do not use the dishwasher, steel wool, or strong soaps that strip seasoning.
• Air‑dry fully and store in a sealed bag to prevent rust when not in use.

Will this fit my grill and how do I confirm compatibility?

Fitment depends on your kamado's internal diameter and accessory clearances; this unit is designed for 18" large Big Green Egg and compatible 18" kamado models like AKORN. Measure your grill’s internal cooking ring or existing plate setter before ordering to ensure a proper fit.

• Overall diameter: 18" (measure your grill’s inner dimension).
• Height: 2.5" total; check lid clearance when using pizza stones or tall roasts.
• If in doubt, compare to your current plate setter or contact the grill maker for internal dimensions.

Who is this for? The Hongso 18" Plate Setter Conveggtor suits home grillers and backyard chefs who want to expand their kamado’s capabilities beyond direct grilling. It’s ideal for pizza lovers seeking a crisp crust, cooks who roast or bake in the kamado, and anyone needing steadier, more even heat across a large cooking surface. Make sure your grill measures 18" internally and follow the simple seasoning and cleaning guidelines to get long, reliable service from the cast‑iron plate setter.
