Industrial Resistance Furnace

With excellent reliability and wide applicability, our industrial resistance furnace has become the core equipment in the heavy machinery manufacturing industry, and can be used for overall heat treatment of large structural parts such as excavator arms, crane girders and shield machine cutter heads to ensure that the workpieces have sufficient strength and fatigue resistance. In the shipbuilding field, the equipment is suitable for post-weld stress relief treatment of ship crankshafts, propellers and hull steel plates, meeting the strict quality standards of the shipbuilding industry. At the same time, the product is widely used in the wind power equipment industry, and can complete heat treatment of key components such as wind power gearboxes, main shafts and blade flanges, ensuring the service life of wind power equipment for more than 20 years. In response to the needs of the rail transit industry, our equipment can carry out precision heat treatment of core components such as high-speed railway wheels, axles and bogies to ensure the safety and stability of train operation.

We have established a full-process industrial-grade quality control system for industrial resistance furnaces, focusing on strengthening the detection of structural strength and operation reliability. All steel structural parts are subject to material inspection before blanking to ensure compliance with national standards; gas shielded welding process is adopted for welding, and 100% ultrasonic flaw detection is carried out for key welds to eliminate welding defects. After the bogie load-bearing components are assembled, a 125% rated load static load test is carried out for 24 hours without deformation or cracking before entering the next process. After the electrical system is assembled, it will undergo withstand voltage test, insulation test and continuous 72-hour power-on operation test to ensure stable operation in the complex industrial electromagnetic environment. Before the equipment leaves the factory, we will conduct a load test simulating the actual production conditions of customers, and all performance indicators will be up to standard before shipment. We accept full-process supervision by third-party testing institutions designated by customers to ensure that product quality meets international industrial standards.

We always adhere to high-standard production. The design, manufacture and inspection of industrial resistance furnaces strictly follow the ISO9001:2000 quality management system standard, and a quality control process covering the whole product life cycle has been established. We are an executive director unit of Zhejiang Heat Treatment Society, Shanghai Heat Treatment Association and Shanghai Forging Association, and participate in the formulation and revision of a number of industry standards. The company has independent goods and technology import and export rights, and its products meet the EU CE safety standard and US UL certification requirements, and can be directly exported to more than 100 countries and regions around the world. We have 3 national utility model patents, among which the "industrial furnace energy-saving thermal insulation structure" and "intelligent temperature control system" have been widely used in our industrial resistance furnace series products, significantly improving the energy-saving effect and automation level of the equipment.
