Application of customized box type resistance atmosphere furnace in the metal industry

The customized box type resistance atmosphere furnace is widely and crucially used in the metal industry. The following will elaborate on multiple specific application scenarios and advantages:

Application scenarios
Heat treatment process
Annealing: Heating the metal to a certain temperature and keeping it warm to release internal stress and optimize the structure. Customized box type resistance atmosphere furnace can stably control the temperature during annealing process, and can introduce specific atmospheres (such as nitrogen, hydrogen, etc.) according to the type of metal and process requirements to prevent metal oxidation and ensure metal stability.
Quenching: Rapidly cooling the heated metal to obtain hardness and strength. Customized furnaces can quickly heat up to the desired quenching temperature, while precisely controlling the atmosphere inside the furnace to avoid metal surface oxidation and ensure quenching quality.
Tempering: As an important process for restoring toughness after quenching, the uniform heating characteristics of customized furnaces can ensure the consistency of tempering temperature and effectively improve the comprehensive performance of metals.
Automotive parts manufacturing: Valve springs for automotive engines are usually made of spring steel with high carbon content. During the production process, customized box type resistance atmosphere furnaces are used to quench and temper the valve springs. If the valve spring is heated to 850 ℃ -880 ℃ and quickly quenched in oil, then tempered in a furnace at 450 ℃ -500 ℃, it can achieve high strength and elastic limit, meet the performance requirements of the engine for valve springs during high-speed operation, and improve the reliability and durability of the engine.
Aerospace field: High temperature alloy blades of aircraft engines are one of the key components, and their performance directly affects the performance and reliability of the engine. Using customized furnaces for solid solution treatment and aging treatment of high-temperature alloy blades, such as solution treatment in a furnace at 1050 ℃ -1100 ℃ and aging treatment at 750 ℃ -850 ℃, can achieve good high-temperature strength, fatigue resistance, and oxidation resistance of the blades, meeting the requirements of aircraft engines for use in harsh conditions such as high temperature, high pressure, and high speed.
Mold manufacturing: Mold steel needs to be pre treated before manufacturing molds to improve its processing performance and structural properties. Customized box type resistance atmosphere furnace can be used for spheroidization annealing treatment of mold steel. For example, Cr12MoV mold steel can be heated to 780 ℃ -800 ℃, kept for 2h -4h, and then slowly cooled to below 500 ℃ in the furnace before being air cooled out of the furnace. This can spheroidize carbides in the mold steel, reduce hardness, improve cutting and processing performance, prepare the structure for subsequent processing and final heat treatment, and ultimately improve the accuracy and service life of the mold.
Metal Melting
Customized box type resistance atmosphere furnaces are widely used in small batch, high-precision metal alloy production. Due to its fast and controllable heating process, it can achieve precise temperature regulation for different metal melting process requirements.
Different types of metals, such as aluminum, copper, stainless steel, etc., have different temperature and atmosphere requirements during the melting process. Customized furnaces can achieve optimal melting conditions for each metal through their multi-stage temperature control system, providing high-quality metal materials for subsequent casting and forming.
powder metallurgy
Used for sintering metal powders to prepare high-performance engineering components. Customized box type resistance atmosphere furnace can accurately control sintering temperature, atmosphere, time and other parameters according to the requirements of powder metallurgy process, ensuring the quality and performance of sintered products.
Alloy Melting and Composition Control
Ensure the uniformity and purity of alloy composition in high temperature environments. Customized furnaces can precisely control the melting temperature and atmosphere, avoiding oxidation, volatilization, or segregation of alloy elements during the melting process, ensuring the quality and performance of the alloy.
advantage
Accurate temperature control: Customized box type resistance atmosphere furnaces are usually equipped with high-precision temperature control systems, which can accurately set and monitor the temperature in real time, meeting the strict temperature requirements of different metal heat treatment and melting processes.
Flexible atmosphere regulation: Different atmospheres (such as inert gases, reducing gases, etc.) can be introduced according to the characteristics and process requirements of the metal material to prevent oxidation or other adverse reactions at high temperatures, ensuring the quality and performance of the metal.
Customized design: The furnace size, heating power, temperature uniformity, atmosphere control system, etc. can be customized according to the specific needs of the metal industry to meet different production scales and process requirements.
