1. News Overview
Recently, a complete customized bar heat treatment production line equipped with a compact casting experimental furnace has been officially put into trial operation in a domestic metal material laboratory. This customized production line is mainly used for heat treatment process verification and small-batch trial production of carbon steel, alloy steel, and stainless steel bars. It effectively solves the pain points of high energy consumption, large temperature difference, and inconvenient parameter debugging in traditional small casting and heat treatment equipment. The stable operation data in the trial period shows that the equipment has excellent temperature control accuracy, energy-saving performance and operational flexibility, providing a reliable experimental and trial production solution for material research and development enterprises, metal casting factories and scientific research laboratories.
2. Project Background
With the upgrading requirements of high-precision bar materials in machinery manufacturing, automobile parts and metallurgical industries, enterprises and scientific research institutions have higher and higher requirements for heat treatment process verification. Traditional large-scale bar heat treatment production lines are costly, occupy a large area, and are not suitable for laboratory small-batch sample testing. Moreover, the independent casting experimental furnaces on the market have problems such as single heating function, poor compatibility with heat treatment production lines, and unstable temperature uniformity.
In response to the above industry demands, the equipment manufacturer optimizes and integrates the technological process, independently develops a compact casting experimental furnace, and matches it with an intelligent bar heat treatment production line. The integrated equipment realizes one-stop processing including raw material melting, casting forming, quenching, tempering and annealing of bar samples, which greatly shortens the experimental cycle of material performance testing.
3. Core Equipment Configuration & Technical Parameters
3.1 Bar Heat Treatment Production Line
The production line adopts advanced
intermediate-frequency induction heating system, which is specially designed for round steel bars with a diameter of 10-120 mm. It supports continuous heat treatment processes such as quenching, tempering and normalizing. Equipped with an intelligent constant temperature control system, the internal temperature deviation is controlled within ±5℃. The production line is equipped with an automatic feeding and discharging mechanism, which reduces manual intervention and improves processing consistency. In addition, the closed circulating cooling system effectively reduces water resource consumption and meets industrial environmental protection standards.
3.2 Small Casting Experimental Furnace
The matched small casting experimental furnace is a periodic energy-saving melting furnace, adopting drawer-type trolley structure, which is easy to load and unload materials. The furnace body is made of high-temperature resistant refractory materials, with good thermal insulation performance. The rated melting temperature can reach 1650℃, which is applicable to melting and casting of ductile iron, gray cast iron, high chromium wear-resistant steel and other metal materials. The equipment is compact in size, covers an area of less than 5 square meters, and is suitable for laboratory layout. It can complete preheating to casting molding within 30 minutes, and the energy-saving effect is prominent, with a power saving rate of up to 60% compared with traditional experimental furnaces.
4. On-site Operation Effect & Case Advantages
4.1 Stable Process Performance
During the one-month trial operation, the integrated production line completed more than 200 groups of bar casting and heat treatment experiments. The metallographic structure of the processed bar samples is uniform, the hardness fluctuation range is controlled within 2HRC, and the product qualification rate reaches 99.2%. The multi-temperature zone independent temperature control system eliminates the defect of excessive local temperature difference in the furnace, ensuring the repeatability and accuracy of experimental data.
4.2 Energy Saving and Environmental Protection
Different from traditional open heating furnaces, this set of equipment adopts fully enclosed heat preservation design and dust removal and exhaust devices. No harmful flue gas is discharged during the casting and heating process. The circulating
water cooling system and optimized heating element layout reduce heat loss. According to the operation data statistics, the annual power saving of the equipment can reach more than 50,000 kWh, which significantly reduces the operating cost for the laboratory.
4.3 Strong Compatibility and Flexibility
The small casting experimental furnace can work independently or be connected with the bar heat treatment production line through the conveying mechanism to realize seamless docking of casting and heat treatment. The equipment supports customized temperature curves and processing parameters, which can meet the experimental requirements of different materials such as spring steel, bearing steel and cold heading steel. It is not only suitable for material formula research and development in laboratories, but also for small-batch customized production of high-precision bar workpieces.
5. Industry Significance & Future Outlook
The successful application of the compact casting experimental furnace matched with the bar heat treatment production line fills the market gap of integrated small-scale casting and heat treatment equipment. It provides a low-cost, high-efficiency experimental verification platform for the metallurgical casting industry, and solves the dilemma of difficult process debugging and high test cost for small-batch bar samples.
In the future, the equipment manufacturer will continue to optimize the intelligent control system, add data monitoring and remote debugging functions, further improve the automation level of the production line, and expand the application scope in new metal materials, special alloy casting and other fields, helping the industry to realize intelligent, green and low-cost heat treatment processing.
