Reciprocating grate furnaces are suitable for the commonly used furnace types in slightly high-quality coal and biomass combustion devices. Reciprocating grate mainly consists of fixed grate plates, movable grate plates, transmission mechanism and reciprocating mechanism, etc. The tail end of the movable grate plate is clamped on the movable crossbeam, and the front end is directly placed on the adjacent next-level fixed grate plate, forming a stepped structure and having a certain inclination Angle to facilitate the downward movement of fuel. The movable grate is driven by an electric motor to drive the eccentric wheel and push and pull rods to reciprocate back and forth for a stroke of about 30-100 mm at a frequency of 1-5 times per minute
Gray cast iron support frame HT200-300
Products Description
Core application scenarios
1. Machine tool equipment support
Bed/chassis: Gray cast iron (HT250-300) with high damping (vibration absorption capacity is about 10 times that of steel) significantly reduces equipment vibration noise and ensures machining accuracy.
T-shaped groove track: the combined support platform meets the positioning requirements of large equipment through splicing, and the horizontal deviation is controlled less than 1mm/m, which is used for detection or assembly fixture.
2. Heavy load-bearing structure
Bearings: Using the compressive strength of gray cast iron (about 3-4 times the tensile strength) to bear high radial loads, widely used in mining machinery, transmission system.
Bridge crash barrier bracket: the structure of bull horn elbow (such as 350x83mm) is suitable for steel pipe guardrail, and the surface is sprayed with anti-corrosion paint to protect the main structure of the bridge.
3. Precision inspection tooling
V-shaped positioning frame: single or split V-shaped frame (such as 105×105×80mm) to support shaft workpiece, the symmetry of V-shaped groove is less than 0.01mm, used for geometric measurement.
The use of special performance drive
1. Vibration and noise reduction components
The flake graphite structure of gray cast iron can absorb mechanical vibration energy, which is suitable for engine base, stamping equipment bracket and other noise reduction scenarios.
2. Wear-resistant functional parts
The micro-lubricating characteristics of pearlite matrix + graphite make it the preferred material for machine tool guide rails and brake disc support frames.
3. Low cost complex structural parts
The casting fluidity is excellent, and it can produce support shells with internal cavities or irregular shapes (such as hydraulic valve seats), which is significantly lower than the cost of welded steel structures.
Application restrictions and substitution trends
Disallowed scenarios:
The full load-bearing frame is prohibited to use the portal steel pipe cast iron structure.
Impact load environments (such as forging equipment) need to be changed to ductile iron or cast steel to avoid brittle fracture of gray cast iron.
Lightweight alternatives:
In the automotive field, high strength ductile cast iron (such as SiboDur 800-5) is gradually used to replace the traditional gray cast iron bracket, achieving a weight reduction of more than 30%.
