Pit Type Gas Carburizing Furnace

Pit Type Gas Carburizing Furnace - Vertical Heat Treatment Solution for Deep Case Hardening

When your production demands precise carbon penetration on heavy, long components, our Pit Type Gas Carburizing Furnace delivers proven results. This vertical furnace achieves temperature uniformity of ±5°C (Class 2 per AMS 2750F) and carbon potential control precision of ±0.02%, ensuring consistent case depth across your workload. Built with a high-nickel alloy retort (Cr25Ni20 or SUS310S) and high-speed centrifugal fan for forced atmosphere circulation, the system handles loads up to 50 tons while maintaining thermal stability. Operating temperatures range from 100-1300℃ with power configurations from 5-3000KW, tailored to your specific production requirements.

What Makes This Furnace Different?

Vertical Design Advantages

The pit-type setup offers normal convection and gravity-assisted solidness. Your long shafts, gears, and bars stay vertically situated amid treatment, dispensing with warpage dangers common in flat formats. This plan permits for indeed warm dissemination all through the stack, basic when you're preparing components that weigh a few tons.

Advanced Insulation Structure

We utilize a composite separator framework combining ceramic fiber modules, ultra-lightweight high-strength microsphere vacuum ball bricks, and heavy-duty high-alumina bricks. This multi-layer approach decreases warm misfortune, brings down working costs, and quickens warming cycles. You'll take note the contrast in your vitality bills.

Precise Atmosphere Control

The coordinates PLC framework oversees multi-stage 'boost-diffuse' carbon profiling naturally. Oxygen tests and infrared CO₂ gas analyzers screen air steadiness in genuine time. This exactness anticipates carbide arrange arrangement on your parts whereas accomplishing the correct surface carbon concentration your application requires.

Technical Specifications

How It Works?

Stacking Stage: Your workpieces enter the heater through the best get to opening. The vertical introduction obliges long components like transmission shafts and landing adapt parts without requiring over the top floor space.

Heating Stage: Electric warming components or gas burners raise the inside temperature to your indicated setpoint. The high-speed centrifugal fan strengths warmed air circulation, guaranteeing uniform temperature dispersion over the whole stack zone.

Carburizing Stage: Controlled carbon-rich climate encompasses your parts. The PLC framework consequently alters gas stream rates to keep up exact carbon potential all through the boost and diffuse stages. This makes the solidified surface layer whereas protecting center ductility.

Cooling Stage: Modified cooling arrangements avoid warm stun and guarantee appropriate microstructure arrangement. Extinguishing frameworks can be coordinates based on your metallurgical requirements.

Unloading Stage: Once the cycle completes, lifting gear evacuates the treated stack. The vertical plan disentangles taking care of of overwhelming components.

Where You'll Use This Equipment?

Control Transmission Fabricating: When you're creating expansive gears and shafts for wind turbines or mining hardware, this heater accomplishes profound carburizing layers surpassing 3mm. The vertical plan anticipates auxiliary warpage on components weighing different tons.

Aerospace Component Preparing: Landing adapt components and specialized clasp require strict climate immaculateness and microstructure control. This framework meets those non-negotiable guidelines whereas preparing long, high-value parts.

Automotive Drivetrain Generation: Clump handling of transmission gears and pinions gets to be effective in this controlled carbon-rich environment. The heater handles high-volume loads required for 24/7 car supply chain operations.

Tool and Pass on Fabricating: Warm treatment of long drills, reamers, and cutting devices benefits from the uniform vertical warming design and exact case profundity control.

Quality Control Features

Your quality group will appreciate the built-in confirmation capabilities. The framework underpins Temperature Consistency Overview (TUS) and Framework Precision Test (SAT) conventions. Thermocouple unwavering quality is persistently monitored.

Post-process assessment centers on Compelling Case Profundity (ECD) estimation utilizing the microhardness strategy (Vickers HV0.5) concurring to ISO 2639. Metallographic examination confirms martensite and held austenite levels, regularly accomplishing Review 1-4 classifications.

The heater plan follows to GB/T 9452 and bolsters CQI-9 warm treatment framework evaluation prerequisites.

Frequently Asked Questions

What's the ordinary viable case profundity range?

Depending on cycle time and temperature, you can accomplish case profundities from 0.5mm to over 3mm. Longer cycles at 900-950℃ create more profound infiltration for heavy-duty applications.

Can this heater handle distinctive portion geometries in one load?

Yes, but you'll get best comes about when portion cross-sections are comparable. Blended loads may require longer diffuse times to guarantee uniform carbon dissemination over diverse portion thicknesses.

How frequently does the counter require replacement?

With appropriate support and operation inside indicated parameters, anticipate 3-5 a long time of benefit life. Variables incorporate working temperature, environment corrosiveness, and cycle frequency.

What gas sorts does the framework use?

Typically endothermic gas or nitrogen-methanol blends. We arrange the air era framework based on your accessible utilities and quality requirements.

Is explosion-proof plan available?

Yes, we can join explosion-proof components and security interlocks when preparing in possibly dangerous climates. Indicate this necessity amid the citation phase.

What upkeep plan do you recommend?

Weekly review of thermocouples and environment tests, month to month fan bearing oil, quarterly answer assessment, and yearly full framework calibration guarantee solid operation.
