Product Description

Product Overview

This Wear Resistant Toothed Plate is cast with a Triangular Serrated Grate Bar profile, where each tooth crest supports the fuel bed and each valley forms an even air channel. Typical grades include High Chrome Cast Iron Grate Bar and heat resistant alloy for higher temperature duty, so the Sawtooth Grate Plate keeps its tooth shape longer under abrasive clinker. Segments are machined to tooth pitch tolerance and checked before packing, letting a worn piece be replaced without scrapping the whole grate row. We supply Boiler Grate Spare Parts for chain, step and reciprocating stokers, and as a Grate Bar Manufacturer China we keep drawings of common furnace models on file. Each order ships with material certificates, hardness records and dimensional reports, packed in fumigation-free cases for 15 to 25 days delivery.

Triangular serrated teeth support the fuel bed and form even air channels, so the Wear Resistant Toothed Plate keeps combustion stable and avoids the local hot spots that shorten grate life.

High chrome cast iron gives the Grate Plate a hard wearing surface, and the tooth profile stays sharp longer than plain carbon steel bars, cutting replacement frequency in clinker service.

Each segment is machined to the same tooth pitch, so a Sawtooth Grate Plate row lines up without steps, keeping fine fuel on the bed instead of letting it fall through the joints.

Reinforced tooth roots resist bending when clinker lumps drop onto the bed, keeping the Triangular Tooth Grate Bar flat and the air gap unchanged through the whole working cycle.

Segments are cast and finished as single pieces, letting maintenance replace one worn Grate Bar Wear Plate instead of an entire grate row, which cuts spare parts cost per shutdown.

For sintering strands the Sintering Machine Grate Bar keeps a controlled slot width, so air passes evenly through the bed and the burn-through point stays at the same position along the strand.

Drawing-based customization: send a 2D drawing or 3D model covering tooth pitch, slot width, height and mounting, and we cast the Wear Resistant Toothed Plate to match, confirming a first article before production.

Material customization: choose high chrome cast iron, heat resistant alloy or another grade, and specify hardness and heat treatment so the Grate Bar matches the temperature and abrasion of your furnace.

Profile customization: triangular, trapezoid or stepped tooth profiles can be produced, with tooth height, pitch and air slot adjusted so the Serrated Grate Plate fits your existing stoker without modification.

Packing and branding customization: neutral plywood cases, your shipping marks, rust film and desiccant, or private label cartons with logo and part number, plus mixed loading with seals and pins.

1	High chrome iron gives the Wear Resistant Toothed Plate a hard wearing face, so tooth crests keep their profile through abrasive clinker instead of rounding off, and the row holds its air gap longer.
2	Triangular Serrated Grate Bar geometry supports the fuel bed on the crests and forms even air channels in the valleys, so combustion stays stable across the furnace width without hot spots.
3	Every High Chrome Cast Iron Grate Bar is hardness tested before dispatch and the report travels with the goods, so incoming inspection has a real number to compare with the drawing.
4	Sawtooth Grate Plate segments are machined to a single tooth pitch, so a replaced row lines up without steps and fine fuel stays on the bed instead of dropping into the ash hopper.
5	A reinforced tooth root keeps the Boiler Grate Bar flat when clinker lumps fall onto the bed, so the air gap stays constant along the row and combustion does not drift towards one side of the furnace.
6	The Chain Grate Bar profile is produced for common stoker widths, so one spare parts line covers several boiler models and the store keeps fewer sizes while still covering every unit on site.
7	Step Grate Bar versions use a thicker toe section, which suits reciprocating stokers where the bar is pushed forward and back under load all day, and resists the toe lifting that causes uneven fuel feed.
8	Grate Bar for Chain Grate Boiler is supplied with matching side seals and pins, so the whole row can be renewed in one shutdown window instead of being pieced together over several stops.
9	Heat Resistant Grate Plate grades are selected against the measured strand or cooler inlet temperature, avoiding early scaling and cracking in the hottest zone and keeping the air slot open longer.
10	Sintering Machine Grate Bar slot width is held to drawing, so air passes evenly through the sinter bed, the burn-through point stays at the same position and the strand runs without hot streak defects.
11	Sinter Plant Grate Bar orders can be mixed with cooler plates in one container, cutting freight per piece when a plant renews several wear parts at the same time, and simplifying customs clearance.
12	Cooler Grate Plate slots follow the drawing, distributing cooling air along the full cooler length, so no dead zone forms near the inlet or the discharge end and clinker cools evenly.
13	Clinker Cooler Grate Plate uses the same wear grade as the crusher plate, so one material standard and one inspection rule covers both spare parts families and store keeping stays simple.
14	Crusher Grate Plate teeth are cast with a wider base, giving the plate bending resistance when oversized material hits the top of the grate, and reducing tooth breakage on primary crushing duty.
15	Wear Resistant Cast Iron Grate castings are shot blasted before machining, so sand and scale are removed and the finished face shows clean metal, making surface defects easy to spot at incoming check.
16	Serrated Grate Plate can be supplied in triangular, trapezoid or stepped profiles, so an existing stoker can be re-barred without modifying the frame, and the air pattern can be tuned by profile choice.
17	Triangular Tooth Grate Bar single piece supply lets maintenance replace only the worn segment, which lowers spare parts cost compared with a full row purchase and shortens the shutdown work list.
18	Boiler Grate Spare Parts kits include bars, seals and pins in one box, so the store issues a complete set and the fitter does not have to chase missing items during the shutdown window.
19	Every Grate Bar Casting is checked for blow holes before machining, so porosity does not open up after a few weeks of thermal cycling, avoiding the cracks that start from a hidden gas cavity.
20	Chain Grate Boiler Spare Parts drawings for common models are kept on file, so a repeat order years later is cast to the same dimensions without re-measuring the boiler on site.
21	Reciprocating Grate Bar versions are dimensioned for waste and biomass fuels, where bed depth changes quickly and the bar must keep pushing material evenly without stalling the stoker drive.
22	Biomass Boiler Grate Bar handles straw, wood chip and pellet fuels, with tooth height chosen so the lighter bed is not blown through by under-grate air, keeping the fuel on the grate until burnt out.
23	Coal Boiler Grate Plate is cast in a wear grade matched to ash content, so high ash coal does not wear the tooth crests flat before the next planned outage and the air gap stays predictable.
24	Alloy Grate Bar options include nickel and chromium additions for hotter zones, letting one drawing be supplied in two grades for different positions on the same grate and extending the row life.
25	Grate Bar Wear Plate is a bolt-on design on many models, so a worn plate is swapped with hand tools instead of cutting and re-welding the grate frame, cutting the shutdown to a few hours.
26	Tooth Shaped Grate Segment castings are weight checked against the drawing, keeping the row balanced so the stoker drive does not see uneven load and the chain or linkage runs smoothly.
27	Grate Bar Replacement Parts are stocked for fast shipment, so an unplanned stop caused by a broken bar can be closed without waiting a full production cycle, protecting the plant output plan.
28	Grate Bar Manufacturer China service includes mounting photos and clearance guidance, helping fitters set the row gap correctly on the first attempt and avoid rework after a hot test run.
29	Wear Resistant Grate Bar Supplier quotations are issued from drawing within 24 hours, with MOQ negotiable and export documents prepared in house, so purchasing can move to approval quickly.
30	Wear Resistant Cast Iron Grate and toothed plate orders ship in fumigation-free plywood cases with rust film, arriving dry and undamaged after long ocean transit, ready to go straight into store.

FAQ

1	What is a wear resistant toothed plate?	It is a cast grate segment with triangular teeth; the crests carry the fuel bed and the valleys form air channels for combustion.
2	Which material do you recommend?	High chrome cast iron for abrasive clinker, heat resistant alloy where temperature is higher; final grade is set against your drawing and duty.
3	Can the tooth profile be changed?	Yes. Triangular, trapezoid and stepped profiles are all producible, with tooth height, pitch and slot width adjusted to your stoker.
4	Do you supply single segments or full rows?	Both. Single piece supply lets you replace one worn segment without scrapping the whole row.
5	How is tooth pitch controlled?	Each segment is machined to the drawing pitch and measured per batch, so the row lines up without steps after replacement.
6	Why do bars warp in service?	Usually uneven air distribution or over-temperature; both cause local hot spots. Check the air gap and the grade selection together.
7	Is the air slot width customizable?	Yes, slot width is cast and finished to drawing so cooling or combustion air matches your equipment.
