Technical Parameters

Fire-baked brick machines (also known as imitation stone fire-baked brick forming machines) are a new type of building material machine that uses hydraulic pressing followed by a subsequent fire treatment to transform raw materials (such as gravel, sand, cement, and pigment) into a surface with a texture that mimics the fire-baked texture of natural stone. The fire-baked bricks produced by these machines combine the texture of natural stone with the high strength of concrete, while being more cost-effective and environmentally friendly. They are currently a mainstream building material for municipal roads, plaza paving, and landscape trails.

Unlike traditional fired brick machines, fire-baked brick machines eliminate the need for high-temperature sintering. Instead, they produce bricks through a process of "hydraulic forming" followed by natural curing. They consume only one-third the energy of traditional equipment and eliminate the emission of exhaust gas and dust during the sintering process, complying with current environmental protection regulations.

Daily Maintenance and Care of Fire-Boiled Brick Machines

Hydraulic System Maintenance: Check the hydraulic oil level weekly (must be between the oil gauge lines). Replace the hydraulic oil every three months (use 46# anti-wear hydraulic oil). Clean the hydraulic filter monthly to prevent impurities from clogging the oil lines and causing insufficient pressure.

Mold Maintenance: Apply a release agent (such as a mixture of waste engine oil and diesel) to the mold surface before each production run to prevent bricks from sticking. Polish the mold edges after every 10,000 production runs to ensure dimensional accuracy. During extended downtime, apply anti-rust oil to the mold surface to prevent rust.

Flame System Maintenance: Check the spray gun nozzle daily for blockage. If clogged, clear it with a wire. Check the gas pipeline for leaks weekly (use soapy water to test; no bubbles are considered acceptable) to prevent gas leaks and potential safety incidents.

Electrical System Maintenance: Check for loose connections monthly and clean dust inside the electrical cabinet. Waterproof the electrical cabinet during the rainy season to prevent short circuits. Regularly back up the PLC control system to prevent program loss.

FAQ:

Q1: What is the essential difference between a fire-baked brick machine and a traditional sintered brick machine?
The core differences between the two lie in their production processes and environmental performance:
Traditional sintered brick machines rely on "raw material forming and high-temperature sintering (1000-1200°C)", which consumes large amounts of coal and emits pollutants such as SO₂ and dust. This results in high energy consumption (approximately 8-10 kg of standard coal is consumed to produce 1 m2 of bricks).
Fire-baked brick machines utilize "hydraulic high-pressure forming" combined with surface sintering and natural curing. They eliminate the need for sintering and consume only 30% of the energy of traditional equipment (2-3 kg of standard coal is consumed to produce 1 m2 of bricks). Dust emissions are ≤10 mg/m³ (in compliance with GB13271-2014 standards). They can also utilize solid waste materials, making them more environmentally friendly and compliant with circular economy requirements.
Q2: What is the difference between "fire-baked bricks" produced by fire-baked brick machines and natural sintered stone? The main differences lie in cost, strength, and environmental friendliness:
Natural flamed stone requires the mining of natural rock (such as granite), which is then cut and flamed. This results in high raw material costs (approximately 80-120 yuan/㎡), and the mining process is also detrimental to the environment.
Fire-fired bricks, made from crushed stone, stone dust, and construction waste, cost only 30-50 yuan/㎡ (40%-60% lower). They offer a compressive strength of ≥30 MPa (compared to approximately 25-30 MPa for natural stone) and are more freeze-thaw resistant (no cracks after 25 freeze-thaw cycles at -30°C). They also achieve "solid waste recycling" and are more suitable for large-scale municipal projects.

II. Technical Principles
Q3: Why is "high pressure" emphasized in the "hydraulic forming" process of fire-fired brick machines? How does the pressure affect the finished product? High-pressure forming is key to ensuring the strength of fire-baked bricks:
Fire-baked brick machines typically apply a pressure of 15-30 MPa (equivalent to a 200-300 ton weight per 1 square meter). This allows the raw material particles to adhere tightly and reduces internal porosity (achieving a density of 2.3-2.5 g/cm³).
If the pressure is insufficient (e.g., <15 MPa), the brick density will be low (<2.0 g/cm³), prone to cracking and chipping. The compressive strength may fall below 20 MPa, failing to meet the load-bearing requirements of municipal roads (e.g., ≥25 MPa for sidewalks and ≥30 MPa for driveways).
Q4: Why is the surface "fire treatment" temperature controlled at 800-1200°C? What happens if the temperature is too high or too low?
Temperature control directly impacts the effect of the fire-burned texture and brick quality:

Too low a temperature (<800°C): The aggregate (e.g., quartz) on the brick surface won't fully crack, resulting in a shallow and uneven texture. The anti-slip coefficient may be less than 0.5 (not meeting the municipal requirement of ≥0.6), making it slippery on rainy days.

Too high a temperature (>1200°C): The brick surface may melt, discolor, or even crack, damaging the internal structure. This reduces the flexural strength (possibly less than 3.0 MPa) and shortens the brick's service life.
