24mm lap joint (usually referring to a lap width of 24mm / interface size) heat-resistant and wear-resistant gray cast iron parts are common custom-made items in the industry and can be produced. Common grades:
- HT250 / HT300 (basic wear resistance)
- High silicon gray iron (Si 3.5–5.5%) (heat-resistant up to 500–650°C)
- Cr–Ni alloyed gray iron (dual excellence in heat resistance and wear resistance, suitable for boilers / grates / high-temperature conditions)
Core properties:
- Wear resistance: Graphite self-lubrication and oil retention, suitable for sliding / impact wear
- Heat resistance: Anti-oxidation, anti-thermal deformation, and anti-growth
- Vibration damping, pressure resistance, and easy casting

 

 

 

With the convenient splicing performance of the 24mm standard lap, the shock absorption and compression resistance of gray iron, and the heat resistance (up to 650℃) and wear resistance, the 24-lap heat-resistant and wear-resistant gray iron castings are suitable for high-temperature, high-wear and splicing-required working conditions in various industries, easy to install and replace. The core application scenarios are as follows:

I. Boiler and Incinerator Industry (Core Scenario)

Suitable for various industrial boilers and incinerators, mainly used for grate segments and liners, solving the problems of easy deformation and rapid wear under high temperature.

Boiler Grate Segments: Spliced in series with 24mm lap, able to withstand high temperature of 300~650℃, resist fuel wear, suitable for various boilers, and easy to inspect and replace.

Incinerator Liners: Form a protective layer by splicing, resist high-temperature flue gas (500~600℃) and slag scouring, and extend the service life of equipment.

II. Mining, Crushing and Screening Industry

Suitable for crushing, screening and conveying equipment, forming a wear-resistant protective surface through lap joint to cope with impact, friction and medium-low temperature working conditions.

Crusher Liners: Cover the inner wall of the equipment, resist ore impact and friction, reduce vibration and noise.

Screening Machine Screens: Lap joint ensures flatness and firmness, suitable for screening high-temperature materials, preventing deformation and cracking.

Conveyor Chute Liners: Resist material scouring, suitable for working conditions ≤350℃, and prevent leakage.

III. Metallurgy and High-temperature Equipment Industry

Suitable for metallurgical and heat treatment equipment, using heat-resistant and wear-resistant properties to solve the problems of component oxidation and deformation under high temperature.

Metallurgical Furnace Accessories: Withstand high temperature of 400~650℃, resist impact of metal furnace charge, and protect equipment.

Heat Treatment Pallets: Form a supporting surface through lap joint, withstand high temperature ≤600℃, prevent deformation, and suitable for workpiece heat treatment.

IV. Industrial Platform and Mechanical Foundation Parts Industry

Suitable for large-area splicing scenarios, using compression and wear resistance, used for industrial platforms and mechanical guide rails.

Industrial Wear-resistant Platforms: Laid on the ground by lap joint, resist rolling and friction, suitable for high-temperature environment ≤300℃.

Mechanical Guide Rail Lap Parts: Ensure the guide rail is flat and firm, wear-resistant and shock-absorbing, and extend service life.

V. Other Special Scenarios

According to material selection, it can also be applied to: power plant pulverized coal conveying pipeline liners, building materials industry kiln accessories, large agricultural machinery wear-resistant connectors, etc.

Summary: It is mainly suitable for "high temperature + wear resistance + splicing required" working conditions. The 24mm lap can flexibly adapt to different sizes, and the material can be selected on demand, making it an ideal accessory for reducing maintenance costs.
