Energy-Saving Upgrade of Industrial Long Structural Parts Tempering: Technical Value Interpretation of Ceramic Fiber Module Furnace Linings 2026-03-14 Energy-Saving Upgrade of Industrial Long Structural Parts Tempering: Technical Value Interpretation of Ceramic Fiber Module Furnace Linings   Core Breakthrough of Energy-Saving Upgrade of Industrial Long Structural Parts Tempering: Furnace Lining Technology Innovation   Under the background of dual carbon goals and industrial cost reduction and efficiency increase, the energy-saving upgrade of quenching and tempering heat treatment for industrial long structural parts has become an important direction of industry technology optimization, and the material and structural innovation of furnace lining is the core breakthrough to realize energy saving in the heat treatment process, and also an important technical starting point for the industry to improve production efficiency, enhance product quality and reduce enterprise costs.   Traditional furnace lining materials have large heat storage capacity and high heat loss, which not only increase the energy cost of enterprises, but also easily lead to furnace temperature fluctuation and affect product quality. At the same time, the slow heating efficiency restricts the production progress, which cannot adapt to the 950℃ high temperature and long-cycle quenching and tempering process requirements of long structural parts, so the innovation of furnace lining technology is imminent.   Core Technical Value of Ceramic Fiber Module Furnace Lining: Low Heat Storage + Low Heat Loss, Quality Improvement and Cost Reduction   The application of alumina ceramic fiber module furnace lining provides an efficient solution for the energy-saving upgrade of industrial long structural parts quenching and tempering, and the CAILONEN RJ series gas pit type quenching and tempering furnace is a typical application of this technology, realizing the dual implementation of quality improvement and cost reduction from the core link of the furnace body.   The furnace lining adopts an alumina ceramic fiber module structure, with the characteristics of low heat storage and low thermal conductivity, which greatly reduces furnace heat loss, reduces natural gas fuel consumption and directly helps enterprises reduce energy production costs; the modular design makes the furnace lining heat preservation more uniform and the furnace temperature fluctuation smaller, perfectly adapting to the high temperature maintenance needs of the furnace for long structural parts and effectively improving product quality.   Industrial Synergy Value and Development Trend of Ceramic Fiber Module Furnace Lining, Efficiency Improvement Implementation   Ceramic fiber module furnace lining is not a single energy-saving design, but also can form a synergistic effect with the equipment heating system: combined with the natural gas high-speed pulse burner heating system, it improves heat utilization efficiency while reducing heat loss, accelerates workpiece heating speed, shortens the quenching and tempering process cycle, effectively improving production efficiency, and the flue gas emission is more in line with the GB9078-88 national standard, taking into account environmental protection and production needs.   From the perspective of industry development, the application of alumina ceramic fiber module furnace lining has promoted the upgrading of industrial furnace body heat preservation technology, provided a replicable path for the energy-saving and green development of long structural parts quenching and tempering heat treatment, and also realized the integrated satisfaction of the three core needs of improving production efficiency, enhancing product quality and reducing enterprise costs, becoming an important reference for the subsequent design of industrial gas pit type quenching and tempering furnace.
Roller Shaft Heat Treatment Selection: Key Points for Choosing a Gas Pit Type Quenching and Tempering Furnace with Precision Temperature Control 2026-03-14 Roller Shaft Heat Treatment Selection: Key Points for Choosing a Gas Pit Type Quenching and Tempering Furnace with Precision Temperature Control   Core Selection Consideration: Temperature Control Precision is the Key for Roller Shaft Heat Treatment   In heavy machinery production, the quenching and tempering heat treatment of roller shaft workpieces directly determines the mechanical properties of products. The selection of gas pit type quenching and tempering furnace not only affects process accuracy, but also is directly related to production efficiency, product quality and enterprise cost control, among which temperature control precision is the primary consideration index.   Most roller shafts are heavy long structural parts with a weight of ≤10 tons and a size of ≤φ900x6500mm. Temperature deviation will directly lead to non-compliance of workpiece performance and increased rework rate, which not only reduces production efficiency but also raises enterprise production costs. Therefore, high-precision temperature control equipment should be prioritized during selection.   Core Design Requirements of Gas Pit Type Quenching and Tempering Furnace with Precision Temperature Control   The CAILONEN RJ series gas pit type quenching and tempering furnace achieves stable temperature throughout the heat treatment of roller shafts with a temperature control precision of ±1℃, avoiding temperature deviation problems from the root, directly improving product quality and reducing cost loss caused by rework.   The equipment is equipped with a uniform layout of high-speed pulse burners on both sides, combined with an air-fuel ratio combustion control system. Each burner is equipped with an independent combustion controller, realizing automatic ignition, flame detection and fire alarm gas cut-off, ensuring the stability of the temperature control system at the hardware level, adapting to the mass heat treatment needs of heavy shafts and effectively improving production efficiency.   Practical Selection Points for Roller Shaft Heat Treatment Furnace   In addition to temperature control precision, the selection of gas pit type quenching and tempering furnace needs to match the core parameters of the equipment: the adaptability of heavy workpieces with a loading capacity of ≤10 tons and the customization capacity of furnace size. Matched parameter design can further improve equipment operation efficiency and help enterprises reduce production link costs.   At the same time, it is necessary to confirm whether the flue gas emission of the equipment complies with the GB9078-88 Emission Standard for Industrial Kiln and Furnace Flue Dust, to ensure that the equipment is not only suitable for the production process but also meets the requirements of industrial environmental protection compliance, avoiding additional cost expenditure from the compliance level and taking into account the multiple needs of quality improvement, efficiency improvement and cost reduction.
Prevention and Control of Oxidation and Decarburization in Heat Treatment:Protecting Surface Quality via Sealing and Atmosphere Control 2026-02-28 Prevention and Control of Oxidation and Decarburization in Heat Treatment:Protecting Surface Quality via Sealing and Atmosphere Control   At high temperatures, iron on the workpiece surface readily reacts with oxygen inside the furnace to form scale. Carbon may react with oxygen and carbon dioxide and escape, resulting in decarburization.   This reduces workpiece hardness and fatigue strength, and an excessively thick oxide layer also impairs the precision of subsequent machining.   The higher the temperature and the longer the holding time, the greater the risk of oxidation and decarburization. Low-carbon and medium-carbon steels are especially sensitive to this issue.   The core prevention and control technologies focus on dual control of atmosphere and sealing:   Adopt controlled protective atmosphere. Select nitrogen-based atmosphere, endothermic atmosphere, or ammonia-cracked gas according to process requirements.   Monitor carbon potential in real time using carbon-oxygen probes and infrared analyzers to maintain equilibrium with the surface carbon content of the workpiece, preventing decarburization or excessive carburization.   Upgrade the furnace sealing structure. Use graphite rope or silicone rubber gaskets for furnace doors, inspect and replace aged components weekly.   Conduct regular leak detection on dynamic and static sealing points such as fan shafts and thermocouple penetration devices to ensure a slight positive pressure of 20–40 Pa inside the furnace and prevent air ingress.   Optimize the heating schedule. Reduce the process temperature and shorten the high-temperature holding time while meeting performance requirements.   Use closed structures or protective covers during workpiece transfer to minimize exposure to air.
